Frequently Asked Questions

Since I've installed cork in my home, I'm constantly being asked question about it. Therefore, I decided to write down the most frequently asked question along with the answers.

Why is cork so Unique?

To start with, cork is an all-natural product, whose harvest does not contribute to deforestation of our planet. Cork is harvested every 9 to 14 years from the bark of the cork oak tree, which regenerates itself, leaving the tree unharmed. In fact, cork is considered a 'Green Home Environmental Products,' meaning that it's safe for our environment.

Cork feels warm and soft underfoot. This is because of cork's honeycomb cellular structure, which is comprised of millions of micro-sized air pockets, which helps to provide the cork resiliency, as well as making the cork soft underfoot.

Because of these tiny honeycomb cells, cork can withstand intense pressure. This means that cork will not dent, break down, or be destroyed by heavy traffic, or having heavy furniture or objects placed upon it. Once the pressure is removed, cork starts recovering its shape. However, because cork is pliable, when you have to move heavy equipment over cork flooring such as refrigerator or entertainment center, you must protect your cork flooring prior to moving the heavy furniture as sharp edges can and will cut into the cork flooring.

In addition these same tiny air pockets, which makes up the cork thermal insulates the cork making it non-conductive of heat and cold. This makes cork flooring always feel warm to the touch when compared to stone, ceramic, vinyl, and even hardwood floors.

Cork also is known to repel insects including mites and termites. It also retards mold growth. This is due to a waxy substance called Suberin that cork naturally produces. This waxy Suberin also makes cork water resistant and prevents cork from rotting when submerged under water for any period of time.

How many colors and patterns are available in Cork?

Cork tiles and planking are available in several colors as well as designs including mosaic tiles. The colors of cork flooring range from natural shades of very light to extremely dark hues as well as reds, blues, greens, and even yellows. With cork tiles and planking, you can use your creativity to design a unique floor patter that's completely and exceptionally yours.

How difficult is cork to install and can the average person do-it-themselves?

Installing cork is relatively simple, providing that you have the proper tools and adhesive. In addition, you have to take extreme care in properly preparing the subfloor. Once the subfloor has been properly prepared, you will next establish a centerline and work out toward the walls and entryway. Once you have established the centerline, you will next apply the adhesive, and then align the first tile to the centerline. Once the tile is the correct position, carefully secure the contact between the tile and substrate by using a rubber mallet. Then after you have a few tiles are in place, you can use a small piece of plywood as a tapping board along with the rubber mallet. It is important to understand that once you have tapped the tiles in place, they cannot be removed without damaging the tiles. After the infield has been laid, then you will cut in the perimeter.

After all the tiles have been installed, allow the adhesive to completely dry. You will need to clean all overspill adhesive from around the edges of each tile, using a damp cloth while the adhesive is wet or by simply rubbing the excess adhesive off the edges when the adhesive has dried.

If the cork tiles are natural and unfinished you will immediately have to coat them using urethane or flooring wax. Make sure that you follow the manufacturer's instructions.

What kind of substrate or sub-flooring can cork be installed?

Cork tiles can be applied directly on to of sealed concrete, which is above grade, on plywood sub-floors, or even over primed drywall.

Can cork tiles be installed over other types of floor surfaces such as wood parquet, vinyl tiles, carpet, or ceramic?

The answer for this is, no. Carpeting, vinyl tiles, sheet vinyl, etc., will have to be completely removed and the subfloor sanded until smooth or a new plywood sub-floor will have to be installed prior to installing the cork tiles. The adhesive used to apply the cork will not adhere to other surfaces, resulting in the tiles pulling away.

For ceramic and stone tiles, first you must ensure that non of the tiles are loose, then you will have to float cementious patching cement over tiles to fill in all deflections, and grout lines. It is vital that the subfloor be smooth, flat, and free of all defects as well as clean of all paints, dirt, oil, grease, and other foreign matter. If the subfloor is not smooth and free of all defects, these can transfer through the cork tiles.

Can anyone install cork flooring?

If you are good at do-it-yourself projects, and have installed other types of flooring, then you will probably not have any difficulty. However, if you have never installed any form of flooring, then you may wish to employ a reputable flooring installer who is experienced in installing vinyl, wood, or ceramic tiles. If you decide to have your cork floors professionally installed, ensure that they are familiar with the product and brand that you have chosen.

How difficult are cork tiles to maintain and keep clean?

For the proper maintenance and to protect against moisture leeching into the seams, apply an additional coat of water-based varnish to the tiles after they are installed. Before applying the finish, the tiles must be clean and free of adhesive.

Once you have applied the second coat of finish, to keep the cork tiles clean all you must do is vacuum regularly, or sweep with a fine bristle broom followed by damp moping with a ph balanced cleaner. Do not use any products that contain ammonia or abrasives. You should never wax your cork floors.

Will my cork floors ever need to be refinished?

If you keep your cork floors well maintained they should last for decades. If you apply a cork floor polish, or another topcoat finish once every year or two depending on the traffic your cork floors should not need to be refinished.
