What Kind of Sub-Flooring (Substrate) is Needed?

Cork tiles can be installed directly over concrete or plywood sub-floors and over un-primed drywall.

Plywood sub-floors:

Plywood substrate must be clean and free of all adhesives, paint, grease, oil, dirt and other foreign matter. All fasteners must be recessed from the surface area. All seams and voids can be flashed with cementious patching cement only. (Example: Ardex Feather Finish). Never use a gypsum-based product. Plywood should be installed within specified trade practices. Deflections of no more than 1/8″ in 10 feet should be kept. Plywood should be secured via staples and glue. Nails and screws have a tendency to creep up after some time passes. The use of a self-leveling cement works best, giving a truly leveled floor.

Cement or Concrete substrate:

Cement or concrete must be cured, free of paint, oil, dirt, grease and foreign matter, salts and alkaline, moisture content of less than 2 lbs. per square foot. Cement or concrete must be troweled smooth with a cementious patching cement, free of all voids and nubs. Best results are achieved with a self-leveling cement with deflections of no more than 1/8″ within 10 feet. In both cases, the sub-floor must be smooth, clean and free of any bumps or cracks. Any unevenness will show through the surface of the cork floor. Be sure the floor is swept and vacuumed clean before starting the installation. More technical subfloor information is available.

Can I Install the Cork Tiles over other Floor Surfaces?

(Ceramic Tile, Wood Parquet, Vinyl Tiles, or Carpet)

No. If you have carpeting, vinyl, sheet vinyl, rubber etc., it will need to be removed and either the floor will need to be sanded until smooth or easier, a new plywood sub-floor be installed. (For example: Multi-ply plywood comes in sheets of 48x48x1/4″) The problem exists with the previous adhesive residue in the substrate. The new adhesive will not adhere to such a condition. Best results: use an all purpose type of adhesive and glue and fasten the new plywood in place. Follow the section concerning “plywood sub-floors”. If you have ceramic or stone tiles and they are secure and not loose, float a cementious patching cement over tiles making the surface free of all deflections, grout lines and tile cushioning. The sub-floor must be flat and smooth and free of all paints, dirt, oil, grease and other foreign matter.

Moisture Problems in Sub-floor

You can buy a moisture test kit, known as a calcium chloride test. The moisture reading for installing cork flooring should be at or below 3#/1000ft over 24 hrs. Of course a moisture test tells you the moisture levels only at the time that you do the test. If you want to create a vapor barrier for a damp cement subfloor, you need to purchase Visqueen (plastic) in 4-6mm thickness or use a product like Laticrete. Lay out the Visqueen covering the floor and overlapping the seams by a good 6″. Then tape the seams. Additionally, when you get to the walls, run the Visqueen up the wall about 6-8″. On top of the Visqueen, use a self-leveling cement, approx 1/2″ in thickness. The self-leveling cement will hold the plastic in place, maintain the vapor barrier and give you a nice flat, smooth floor to work on. You can trim off the excess Visqueen at the walls where it extends above the new cement.

Can Cork Floors go over Radiant Heat?

You can install cork tiles over hot water radiant heat (but not electric) as long as the surface temperature does not go above 84 degrees. Because of its insulative properties, the cork will be slower to warm up and slower to cool down that other materials with higher conductivity. However, cork is naturally a warmer floor than any other material except carpeting. At the time of installation, you should have the heat on for 3 days at a warm temperature with the tiles unpacked to allow them to acclimate before installing them. The cork tiles will contract when in contact with a heated surface as well as in dry environments so you’ll want them to do this as much as possible before you glue them down. You want to be sure to use sufficient adhesive also.

Can Cork Tiles be Installed over Vinyl Tiles? Can it be used with Access Flooring?

There are many types of access flooring, most of which the panels screw down. Some have a raised lip around the perimeter of the panel (at a specific height depending upon the floor covering to be used). In either case, surface mounted screw heads will be seen flush with the cork. Floating floors are an interlocking system that engages all 4 sides and not readily used for easy access to raised floors.

Preparing for Installations https://corkfloor.com/preparing-for-installations https://corkfloor.com/preparing-for-installations#respond Fri, 23 Oct 2020 14:47:25 +0000 https://c97389x1.entnet9.com/?p=2078

Before You Install Your Cork Tiles (Opening Boxes & Staining the Floor)

When you receive the boxes of tiles, remove them from the boxes a few days before you’re going to install them. Carefully cut down opposite corners to open the boxes and lift out the tiles. Let the tiles acclimate in to your normal room temperature for roughly 3 days. You should also shuffle the tiles as there is naturally some shading variations and you’d want to mix slightly lighter or darker tiles throughout rather than have them fall all in one section.

Removing Old Adhesive

A mechanical method of removing old adhesive from concrete is called ” Shot Blast”. It’s a machine with a square foot print. Once you’ve finished shot blasting the floor and cleaning up all the residue, you would have to smooth the rough concrete with a cementious patch or a cementious self-leveling cement. Let it cure as per manufacturer’s instructions. Once cured, you can put our cork tiles down directly on the cement floor.

Will Your Adhesive Work on my Floor?

Our water-based latex contact adhesive works fine over hot-water radiant heated floors, concrete and wood. Linoleum and vinyl should be removed or you can put a 1/4″ plywood subfloor over top of it. You need to glue and staple the plywood down and then sand across the joints to one foot on either side so the plywood seams won’t show through.

Installation Questions https://corkfloor.com/installation-questions https://corkfloor.com/installation-questions#respond Fri, 23 Oct 2020 14:46:25 +0000 https://c97389x1.entnet9.com/?p=2081

How is a Cork Floor Installed?

[Click here for detailed instructions] After proper conditions of the substrate are met (see below), the installation continues with the layout of the room area. To establish centerlines in the same manner as other tile installations, run a parallel line from the centerline at the entryway. The substrate is then coated with Globus Cork reciprocal adhesive. The adhesive is applied with a paint roller, (paintbrush for the perimeter), to the substrate. A 3/8″ nap roller generally works best. The reciprocal adhesive must cover 100% of the substrate. Let adhesive dry clear, which usually takes about 45 minutes depending upon the substrate and humidity conditions. (Do not allow any foot traffic to the adhesive area.) Apply reciprocal adhesive to as much of the area of the substrate that will be covered with tile within a day’s work. Installation begins with the first tile aligned to your layout lines. When the tile is in its proper position, secure the contact between the tile and substrate using a rubber mallet. Once a few tiles are in place, you can use a small block of flat wood or plywood as a tapping board for the rubber mallet. Once the tile is tapped, it CANNOT be removed. Continue the installation in the same manner. Cut in the perimeter as you go or when field tile is completed.

Note: Globus Cork tiles are shipped to you pre-glued and must be installed within 40 days from the date of shipment from Globus Cork. If the installation of tile exceeds 40 days from the date of shipping, a refreshing coat of adhesive must be applied to the back of the tile. The adhesive must cover 100% of the back of the tile. Allow adhesive to COMPLETELY dry before proceeding. Clean any and all overspill of adhesive from the edges of each tile. Clean up of adhesive while wet is done by with a damp cloth. Clean up of the adhesive when dry is done by simply rubbing the excess adhesive off the edges like rubber cement.

You need to apply the reciprocal adhesive to the substrate for proper installation. The adhesive is available in 1 gal. tubs at an additional charge from Globus Cork and will be shipped with your order. Request it when you place your order.

Who can install it?

A reputable flooring installer who is comfortable with installing vinyl, wood or ceramic tiles can install Globus Cork tiles. We do provide telephone consultations to anyone installing our tiles. Many of our homeowner customers consider this a DYI project. If you have some experience laying vinyl tiles, you might want to install the cork tiles yourself. Our product is shipped with an installation guide. If you choose to use a flooring installer, have them give us a call to fine-tune their cork installation practices or ask questions about substrate floor preparation.

Installer Selection

You should look for a local flooring installer that lays luxury vinyl tiles or ceramic tiles in a precise and professional manner . Our tiles are very easy to install and the skill is more in the attention to details, tight fits and straight lines. There are no special tools required to install our tiles and we do give free telephone consultations to any installer that calls us. Please take a look at our installation slideshows. Many homeowners actually install the tiles themselves.

Restaurant Installs

Daily care is easy with a damp mop and a mild detergent. Don’t use any bleach, abrasives or ammonia products (think of this as a wood, which it is). In a restaurant situation, you’ll want to make sure that the porters don’t dump a bucket of water down and then mop it up. You don’t want to get a lot of water under the tiles. The water doesn’t damage the cork or finish but it can loosen the water-based adhesives that we use. So if you wet mop or spray down the kitchen areas, you’ll want to have a transition piece between the areas to keep the soaking water away from the finished dining room floor. We don’t recommend using cork in commercial kitchens because of the typical cleaning techniques in restaurants.

Quick Wall Installation Instructions

For wall installation, first draw your horizontal and vertical lines that you’ll need to line up the start of your tiles. The wall surface (drywall or plywood) should not be painted or primed. If it has been, you’ll need to rough up the surface with a light sandpaper sanding and then remove the dust so the adhesive can get a good grip. Next simply roll our adhesive on the wall or you can use a paint brush to apply the adhesive if its a small area. Wait until the adhesive dries to tacky and clear state (about 30- 45 mins.) and you’ll be able to see your lines again.

Important: After the first coat of adhesive is dry (and clear), apply a second light coat of adhesive and let that dry. This ensures that you have the appropriate amount of adhesive for a vertical surface.

To install the tile, align one corner of the tile against your 2 lines and then carefully push down the rest of that tile. Press tightly against the first tile with the edge of the next tile to tightly align it to the first one and continue to stick the tiles to the wall. Carefully place each tile tightly against the next one because once the tile sticks, its very difficult to remove. When the tile is in place, smack the tile with the palm of your hand to hold it temporarily and then hit with a rubber mallet or a hammer and batten board all across the tile to ensure that all parts of the tile have made positive contact with the wall adhesive. You should not have any gaps between tiles when installed correctly.

Installing on Painted or Sealed Concrete Floors

A cement subfloor should not have a sealer, paint, or primer on it.

If the cork were to be applied to painted concrete, the cork could pull up any loose paint might not get a grip into the cement. You can shot-blast the concrete to remove the paint, put a patching cement over the top if the paint is secure or put down a plywood subfloor. You should not use any chemical paint removers as this will seep into the concrete and cause an adhesion problem.

Dry Climates- Low Humidity

Humidity levels for installation and use of cork flooring or any other wood should be above 50%. If you have low humidity in your area, this will cause cork (as a wood) to contract so you want to let the tiles acclimate for at least a week before putting them down. Once down, the base of the tile will always be tight on the floor and will not move but the surface area of the tiles can still contract. The effect of that will be that the seams between the tiles may look larger. Extremely low humidity levels will cause more extreme contraction and could even change the shape and dimensions of the tiles. The tiles will not all contract in the same manner as there is no dimensional stability in cork such as there is in hardwood which also contracts. Larger tiles will contract visibly more than smaller tiles, especially 24″x24″ tiles. Installers need to take extra time to make adjustments when laying the tiles in order to adhere to required pattern alignment. Techniques such as compression fitting should be used rather than trimming any tiles. Globus Cork can provide more information on this technique by calling our technical service at: 718.742.7264.

Am I Restricted to the Colors & Patterns on your Website?

A talented designer can envision many color and design possibilities in flooring. We encourage such creativity and offer tile layout patterns as well as some photos to help spark new ideas. Additionally, we can also cut cork tiles to your custom specifications.

We are always working on new colors and try to keep our website up to date. We also have the ability to modify one of our current colors as well as developing a custom color for you. If you have a color sample that you’d like us to match, contact us and we’ll discuss how to proceed. There are minimum order of 100 sq. ft per custom color along with a custom surcharge.

Do You Send Out Samples?

We do send out color samples within the US so people can see our product. If you’d like to receive samples (up to 3 for free), please let us know your color selection along with your mailing address. Additional samples are $1.50 each. The samples are 4×4″ in size.

What are the Standard Tile Sizes?

6×9 — 6×12 — 6×18 — 6×24 — 6×36 — 9×9 — 9×12 — 9×18 — 9×24 — 9×36 — 12×12 — 12×18 — 12×24 — 12×36

What about Thicker Cork Tiles?

Some cork manufacturers sell a thicker tile (5/16″ is another common size). Thicker tiles are stiff and tend to cup up at the edges when installed, especially when installed using a common “wet” adhesive like DriTac. This is a single part adhesive that is troweled down thick enough to ooze up around the tiles. You have a wet material along the bottom of a dry tile and the cork is going to react during the hours of cure time as DriTac sets up and dries. This is a standard install practice in the industry and it is a source of problems.

Our approach is very different because we’ve taken all these problems into consideration and use different adhesives and finishes which are higher quality and also a bit more expensive. The first difference is our cork which is 4mm or 3/16″ thick. This tile has more flexibility than the 5/16″ size which is stiff. We use only a contact adhesive which is similar to a rubber cement application. Both the tile and the subfloor surface have the adhesive rolled on them with a paint roller. We apply the adhesive to the tiles here at the factory where they dry to slightly tacky before shipping. The installer rolls the same adhesive on the subfloor and waits 1 hour til it is tacky. When you stick the tacky tile to the tacky subfloor, the bond is immediate and extremely strong. No cure time and no movement. This also means that the tile can not warp, cup or curl. The tile is essentially molded tight to the floor. The only way that the cork moves from that point forward is the surface part of the tile in response to temperature and humidity changes. This is also why we put a micro-beveled edge on the floor tiles. This allows for movement in the top of the tile without the possibility of one tile expanding and peaking over the other which could occur with a 90 degree angle tight against another 90 degree.

Maintenance of Cork Floors https://corkfloor.com/maintenance-of-cork-floors https://corkfloor.com/maintenance-of-cork-floors#respond Fri, 23 Oct 2020 14:44:05 +0000 https://c97389x1.entnet9.com/?p=2110

Can you give me a Maintenance Overview?

The Globus Cork tiles arrive at you prefinished with a premium water-based finish and preglued. For best results and protection from moisture leeching into the seams, an additional coat of the same varnish is being applied after the tiles are installed at your location. Globus Cork sells this premium commercial-grade varnish and will ship it with your tile order. Tiles must be clean and free of adhesive, dust and dirt before the final coat of varnish is applied. Regular cleaning with a vacuum, fine bristle broom, or a damp mop with a ph-balanced cleaner Avoid products with ammonia or abrasives. Periodically you should refresh the finish layer on the tiles. Either a new layer of the topcoat of finish can be applied or use Globus Floor Polish which produces a protective wear layer for Globus Cork tiles.

This application can be applied once every year or so depending upon the traffic on the floor. You will never be stripping or buffing your floors.

What about Cleaning?

You should vacuum your cork floor regularly and for more thorough cleaning, damp mop it with a mild soap. Use only a slightly damp soapy mop to clean and then wipe over it again with a clean slightly damp mop to pick up the soap residue. You should use a mild Ph-balanced soap like Liquid Joy dish soap and never an ammonia-type or abrasive product. Globus Cork will sell a Concentrated Cleaning product, which you can purchase directly from us. You should never wax your floor. We do not recommend steam cleaning cork flooring as it is not good for wood floors.

Never use an abrasive or ammonia-based cleaning product!

Sweep, vacuum, or damp mop the installed floor regularly. Do not flood the floor with water.

Clean the floor by using a damp mop regularly with a ph-balanced detergent such as Liquid Joy to clean and keep the surface free of grit or sand. You can also purchase a concentrated cleaner from us.

Refresh the finish on the tiles on a regular basis with another coat of our finish or our floor polish product. Apply once or twice a year for a residential installation and more frequently for a commercial installation. Frequency is dependent upon usage.

Should I keep the Tiles Sealed and Varnished?

This application can be applied once every year or so depending upon the traffic on the floor. You will never be stripping or buffing your floors.

How Often Does the Floor Need to be Refinished?

A well-maintained cork floor will last for decades. Depending on how much foot traffic the floor receives, you’ll want to apply Globus Cork Floor Polish or another top coat of finish on a regular basis. This could be once every year or two in a residential location or several times a year in a busy retail location.

Durability – Cork Floors Are Tough! https://corkfloor.com/durability-cork-floors-are-tough https://corkfloor.com/durability-cork-floors-are-tough#respond Fri, 23 Oct 2020 14:43:04 +0000 https://c97389x1.entnet9.com/?p=2116

What about Cork and Water?

Cork does not absorb water or liquids which is why it’s been used for centuries to float fishermen’s nets and as stoppers for wine bottles. Finished cork glue-down tiles are great for kitchens and baths and Globus Cork will not stain as it has several coats of finish on it. We use only solvent-free, water-based products in the manufacturing of our cork tiles and that includes the adhesive also. If you have a flooding situation (ie: not daily usage), the standing water could possibly re-emulsify the adhesive and thus loosen a few tiles. That’s the only foreseeable damage that might be possible by water but this does not typically happen. The tiles can usually be dried out and reapplied with new adhesive after the subfloor has dried also.

Cork does not absorb water and mold does not grow on cork so water, moisture or high humidity is not a problem with glue-down cork tiles. Floating floors which have a center fiberboard are not recommended for water areas because they are mostly fiberboard and can swell when they get wet. If floating floors buckle, they cannot be saved and will have to be replaced. Only the 100% cork tiles which are a glue-down product are recommended for any potentially wet areas.

How Durable is Cork?

You should vacuum your cork floor regularly and for more thorough cleaning, damp mop it with a mild soap. Use only a slightly damp soapy mop to clean and then wipe over it again with a clean slightly damp mop to pick up the soap residue. You should use a mild Ph-balanced soap like Liquid Joy dish soap and never an ammonia-type or abrasive product.

Refresh the finish on the tiles on a regular basis with another coat of our finish or our floor polish product. Apply once or twice a year for a residential installation and more frequently for a commercial installation. Frequency is dependent upon usage.

Will Heavy Usage Wear Through the Color?

Wear on your floor will always be on the finish layers. There are 4 layers of finish on the tiles by the time the install is completed. Our recommendation is to use a polish product which is a thinner version of the finish for on-going maintenance. “Frequency is dependent upon usage”. You can also At no point should you be walking on the cork without finish on it so there is no way to wear off the color. The finish is a wear layer that protects the cork. If damage occurs to the cork such as a gouge or scrap which removes the finish, color, and some of the actual cork, then you’ll need to do a repair by either re-staining the cork or replacing a tile or panel. When you calculate the overage in order, you should plan on having a few leftovers for possible replacements. The majority of residential installations are kitchens, followed by bathrooms. Our cork is installed in commercial locations that have much higher use than homes and it holds up fine. Cork will last many decades although it will age just like other woods and can fade in direct sunlight without UV protection just like other woods.

What About Cat or Dog Pee?

The cork does not absorb liquids and it would be difficult to stain it due to the multiple layers of finish on the cork. If your pet repeatedly pees at the same spot then over time, the ammonia might start to degrade the finish over time so try to prevent that from occurring.

Will Large Dogs Damage the Tiles?

If you have large dogs at home or dogs that love to race through the house, then you know they have the ability to scratch almost any surface – resilient, wood or even harder surfaces. Just walking on a cork floor by a heavy dog will not cause any damage. As a basic comparison, cork holds up better than hardwood floors because it gives under foot. Our commercial grade finish will minimize the appearance of scratches in the finish coat. You can also use a cork floor polish or apply a new finish coat as needed to refresh the floor which will fill in any scratches that are in the finish layers. You can replace a single tile if necessary.

Rolling Office Chairs

We’ve not found there to be any problems with rolling office chairs. We have cork in our offices and don’t have any scratching from the rolling chairs. However, it is best to have rubber wheels on the rolling chairs and not the inexpensive plastic wheels.

What About Heavy Weights or Home Gyms?

Glue-down cork tiles which are 100% cork are the best choice for a home gym. We don’t recommend the floating floors under heavy equipment for 2 reasons. First, the floors are supposed to “float” on top of the subfloor which allows them to expand and contract as the wood needs to do. If they are pinned down, they can’t do this. Secondly, the engineered floating floors have a center fiberboard (MDF) which is not resilient like cork is. Since the cork is adhered to this fiberboard, it cannot react independently of it. Therefore dents will be permanent in a floating floor panel but they would not be permanent in a glue-down tile.

Can Cork Fade?

As cork is a wood, it can fade and age like other woods. The addition of color to the cork provides our cork with a measure of protection as does the varnish that we use which has some UV protection. Our colored cork will fade less quickly than uncolored cork. Within our color range, darker colors fade less than lighter colors as measured in xenon fade tests. However, all cork will fade from UV rays.

If you would really enjoy living on a cork floor and you want to place the cork in front of strong direct sunlight, the best bet would be to treat your windows. You could give all your home furnishings some UV protection that way! Investigate a product like this: www.energy-film.com

Low E Glass Windows

Even the highest performing low-E products can come up short on UV protection. Low-e glass will not protect your furnishings from fading. You need a special window film that blocks UV radiation.

Will the Finish Peel Off?

Every cork manufacturer uses different finishes and different adhesives. Some cork manufacturers will even put a vinyl layer on top of the cork. Over time the vinyl edges begin to separate from the cork tiles and peel. Our product is 100% cork so this can not happen with our tiles. Some manufactures use a less expensive hardwood finish on their cork tiles. The hardwood finish is too inflexible for cork and in a short amount of time, it will develop spider cracks as the cork gives under foot but the finish doesn’t. Globus Cork only uses and recommends a European finish that is formulated specifically for cork. It is a water-based varnish that does not crack, peel or separate. It is possible to apply too many coats of finish in the on-going maintenance of the floor and have dirt trapped in between the layers of finish. This could cause some peeling to occur. For this reason, we suggest using our cork polish product for ongoing floor care.

No. If you have vinyl tiles, sheet vinyl, rubber, etc., it will need to be either removed and the floor will need to be sanded until smooth OR best option, a new plywood subfloor should be installed. (For example, Multi-ply plywood comes in sheets of 48x48x1/4″) The problem exists with the previous adhesive residue in the substrate. The new adhesive will not adhere to such a condition. For best results when installing a new plywood substrate: use an all-purpose type of adhesive (not a contact adhesive) and glue plus staple the new plywood subfloor in place.

Does Cork Dent?

Cork has a unique honey-combed structure that is filled with an air-like gas. The cork cell membranes are very flexible allowing cork to be both compressible and elastic. When cork is subjected to pressure or heavy weights, the air in the cells is compressed. An example would be when a cork stopper is pressed into a bottle opening. Once the pressure is released (or in the example, the cork is removed from the bottle), cork returns to within 80-95% its original shape over a short period of time. In cork flooring, this means that although its possible to make a dent in cork with a heavy object or high-heeled shoes, the cork will probably recover to near its original shape, unlike hardwood floors which can not recover. Placing pads under heavy objects to cushion or disperse the weight will help. Also as a last resort, you can replace single tiles in those dented spots as you should also order a few extras to hold on to.

What About Scratching?

Wear and tear on a floor means walking on it. Thats the normal wear you should consider. Cork floors are in the Library of Congress for many decades now as well as many other public libraries, court houses and churches since the 1920s, 30s and 40s. If you draw a sharp edge across it you’ll have a scratch just as you can scratch many other flooring materials. Even hard surfaces like granite or stone can be scratched.

Water Damage Repair

If you have a flooding situation (ie: not daily usage), the standing water could possibly re-emulsify some of the adhesive and thus loosen a few tiles. This does not typically happen. That’s the only foreseeable damage that might be possible by water. If a few tiles loosen, the tiles can usually be dried out and reapplied with new adhesive after the subfloor has dried also. So the first step is to use fans and dehumidifier in the room for a few days to see what the actual need is. Use our adhesive on the backs of the tiles and subfloor and follow our installation instructions. Let the adhesive on the tile and subfloor dry to a tacky state before sticking the tile down. If the tile is still partially attached to the floor, prop up the tile with toothpicks or small shims of wood to keep them separate while the adhesive tacks up.

If you need to order replacement tiles, we’ll need a small piece of the original cork tile for a color match. All cork products are made to order in a batch process strictly for you and additionally cork will age over tile and can shift in color. An aged cork tile will be difficult to match with a freshly colored cork tile. If you installed a cork floating floor, the fiberboard center will be permanently warped and cannot be fixed. You would need to order a new floor.

What About Curling?

Cork, as a wood product, has some characteristics similar to hardwoods in that it expands and contracts with changes in temp & humidity. That’s why its so important to acclimate the product in your home (not garage) at your living room temperature (not in new construction without the heat on). These are problems common to all wood products.

Can Cork go in a Kitchen, Bathroom, or Laundry room?

Finished cork in glue-down tiles are great for kitchens and baths. We use only solvent-free, water-based products in the manufacturing of our cork tiles and that includes the adhesive also. You do need to put down a top coat of finish after the tiles are installed to protect the underlying adhesive from water. Caulking around the tub, sink and toilet in bathrooms also helps. Cork does not absorb water and mold does not grow on cork either so water or moisture is not a problem with glue-down cork tiles. Floating floors are not recommended for water areas because they are mostly fiberboard and can swell when they get wet. Only the 100% cork tiles which are a glue-down product are recommended for any potentially wet areas.

Cork flooring on stairs

You can use glue-down cork tiles on both the riser and tread of a staircase. You will need to use a nosing on the front edge of the step to protect the tiles from chipping. The wood or metal nosings are available at large hardware stores in both wood and metal.

Can the Cork Tiles be used as a Bulletin Board?

Yes, you can use the cork tiles as a bulletin board as long as you are mounting it to dry wall. You could also put it in a picture frame or mount it on foam board. The cork tiles are 3/16″ so a thumbtack will stay within the cork and a pushpin will extend through the cork into the sub-surface.

What is Cork & Why is it so Unique

Cork is an all-natural product, harvested from the bark of the cork oak tree. Perfect for green construction, cork oak is the only tree whose bark regenerates itself after harvest, leaving the tree unharmed. The bark is harvested every 9 years as mandated by governmental agencies resulting in an all-natural, environmentally responsible product with exceptional physical properties. Aside from the rich texture, numerous patterns, and beautiful colours of Globus Cork tiles, cork flooring is appreciated for its soft give under foot, resistance to dents, and its thermal & acoustical insulative qualities. Review all the benefits of cork.

Softness

The first thing most people notice about cork is how soft it feels underfoot. Soft enough that your back, hips and knees feel better after standing on your feet for long periods of time but yet it doesn’t feel spongy. Cork’s cellular structure is made up of millions of tiny, sealed air-like pockets which provides many of the benefits of cork. This provides the soft feel underfoot.

Resistance To Moisture & Liquid Penetration

While natural cork is not completely impervious to moisture penetration, its cellular structure gives it a high resistance to penetration by water. Globus Cork tiles are coated with a premium water-based finish and are highly resistant to stains or water damage. So yes, you can install cork tiles in the kitchen or bathroom.

Resiliency

Heavy pressure does not break down or destroy the tiny air cells that are unique to cork, pressure only compresses the air within the cells. The cork begins to spring back when the pressure is removed. This resiliency allows the cork to give under pressure while still maintaining its beauty and finish. In your home this means that if you make a dent in a cork floor, over a short period of time the dent will disappear unlike hardwood flooring which maintains a permanent dent. However if you need to move heavy equipment across the floor such as a piano or refrigerator, protect your floor your floor first before rolling across it. Sharp edges can make cuts in the floor during this move.

Acoustical Insulation & Impact Noise Resistance

Cork, with its 200 million air cells per cubic inch; of which 60% is air, essentially acts as an “air cushion”, absorbing vibrations and direct impacts. This means cork is great for music rooms, recording studios, and entertainment rooms. You should consider cork for your floor, walls or ceiling if you have high ceilings and wide expanses of hard surfaces. Cork will help to muffle the sound or noise in these situations.

Thermal Insulation

The minutely divided air spaces within cork make it one of the most efficient non-conductors of heat/cold. The unique cell construction of cork provides this property. Additionally, cork maintains a warm temperature in your home. Therefore a cork floor will always feel warmer to the touch than stone, ceramic, vinyl or even hardwood floors. Test have proven this.

Anti-Allergenic

Bugs, mold, mites and even termites are repelled by cork due to a naturally occurring waxy substance in cork called Suberin. So if you’ve removed all your carpeting and installed hard but cold surfaces in your home due to allergies, now you can consider warm, soft cork. Suberin also prevents cork from rotting even when completely submerged under water for long periods of time.

Difference Between Commercial & Residential Cork Floors

The difference between commercial grade or residential is actually in the finishes applied to the cork, not the cork itself as long as it is cork meant for flooring and not bulletin boards. The top sealer coat that is applied to our cork after it is installed is a commercial grade finish formulated expressly for cork, meaning it is strong but also has flexible strength which is needed for cork. Each manufacturer will should be able to tell you what uses are appropriate for their cork, ie residential only or commercial. There are a variety of finishes for cork ranging from a vinyl layer (which can separate) to UV-cured (which is a thin hard layer) to multiple coats of varnish/polyurethane which have different grades.

Temperature and Energy Efficiency

Cork maintains a standard temperature to the touch in that if feels in the 60-70 degree range year round. It doesn’t get very hot or cold. Additionally, cork’s insulating benefits are based upon the existing temperature within a room. Cork will help maintain whatever the ambient temperature is within a room so it will help with energy efficiency. It also is not a conductive material so it does not transfer heat from the surface behind it.

Compare Glue-Down Tiles to Floating Floors

Your planned area of use and the condition of your subfloor are often the determining factors in a decision between glue-down tiles and floating floors. Floating floors are not recommended in water areas such as kitchens and baths because they have a fiberboard center which could swell if sufficient water seeped through the seams. Glue-down tiles are good for kitchens and baths.

Here are some other comparisons:

Subfloors

When installing glue-down tiles, you need to have a nice flat floor – no voids, no bumps as these will telegraph through the tiles. Level is not important but flat is. On a cement floor, any subfloor problems can be easily addressed by the pouring a thin layer of a self-leveling cement down on your current floor. It dries overnight and gives you a beautiful flat surface. Floating floors are a little more forgiving of lumpy surfaces but only moderate bumps and voids. Larger ones will cause uneven alignment of the planks, bouncing, squeaking and possibly even breakage if the bumps are large enough. Floating floors can go over top of linoleum, vinyl tiles, ceramic tiles, meaning that they do not need to be removed first as they do for glue-down tiles. Glue-down tiles are 3/16″ thick and the floating floors are 7/16″ thick.

Appearance

Our glue-down tiles come in more than 20 different sizes and shapes giving you a multitude of design possibilities. The size and shape of the tiles you select is an important design decision. All floor tiles have a small beveled edge so you do see the edges of the tiles. As a wood, cork expands and contract with heat and humidity changes. The beveled edge is necessary to allow the surface of the cork tiles to expand when necessary without tiles peaking or popping over surrounding tiles. The cork floating floor panels are available in only one size (roughly 12″x36″). The cork panels do not have beveled edges and handle expansion differently. Since the cork panels are not adhered to the floor (they’re floating), the entire floor expands when it need to which is why you have spacer gaps where the floor reaches the wall.

Installation

Both products are very easy to install and because our tiles have several coats of finish and are pre-glued, the installation time is about the same. Both products need to have a final top coat of finish applied after installation. Cuts are easier to make in glue-down tiles so if you have a lot of them, this is a consideration. A circular saw is necessary for the floating floor planks. Cleaning is in the same manner for both. Repairs are easier with the glue down tiles because its easier to remove or patch a single tile. Its very tough to remove a single panel of a floating floor if its not at the perimeter of the floor. A floating floor feels a bit harder floor than a glue-down tile floor and is noisier than the 100% cork tiles.

Dimensional Stability

Cork is different from other flooring materials but not difficult to work with. The key to remember is that you are working with wood in a tile form. So although you are laying it down in tiles, cork still acts like a wood. It must be acclimated before you install it. As a wood it will expand with heat, contract with cold, expand with higher humidity and contract with low humidity. During acclimation, the tile can alter its size and shape a bit and unfortunately, it may not expand or contract uniformly. This means that although the tiles can leave the factory perfectly squared, after acclimation either in transit or onsite, the tiles can be slightly out of square. The most common shift can be a slight shrinkage inward at the corners. Our general recommendation is to lay cork tiles in an ashlar pattern (brick) instead of on a grid layout so that your eye is not searching for the straight perfect lines. Cork is a natural material and will not appear as uniform as a vinyl tile.

Cork is different from other woods as it does not have a fibrous structure to help it maintain its shape. Hardwoods have long string-like fibers running horizontally through the planks. Hardwood will shrink or expand primarily in one direction across the grain.

Cork flooring has no structural fibers. If you look at the back of a floor tile, you’ll see that it is made up of small cork pieces. Whether they are coarse or fine, these pieces are simply mixed with a small amount of binder and heated to form the cork in large blocks that are then sliced down into slabs and tiles. This cork form is very durable but it doesn’t have the same dimensional stability that hardwoods have.

Why are there Beveled Edges?

The depth of the bevel on the tiles is approx. 1/16″ which is a third of the depth of the tile. It is also a micro bevel, only about a 5 degree bevel. The beveled edge is a stronger edge than a 90″ angle edge and therefore resists chipping better. The bevel also allows for the natural expansion and contraction to occur which happens with all natural products and the bevel permits this to happen without one tile peaking over another. A tile that pops up would be prone to chipping over time as you walk over the surface. Think of the beveled edge as a safety value.
