Thermally and Acoustically Insulated
The presence in cork of over 100 million air cells per cubic inch and the prism shape of that cellular structure incapacitate the effects of temperature and sound. Cork floors reduce impact noise, a great asset for applications such as multi level housing, office spaces, museums and places of worship.

APPLICATION
CORK to SUBSTRATE
Apply cork adhesive according to manufacture’s instructions. Spread cork adhesive using a 3/32" x 3/32" notched trowel. Apply adhesive only to an area the cork underlayment can be set in the adhesive while it is still wet and tacky. Butt seams together, leaving a 3/8" space around all vertical abutments. Fill in with an appropriate acoustical sealant per manufacture recommendation. As soon as the placement is completed, roll down the entire surface with a 70lb. Linoleum type roller. Roll right angles, inside to outside. This will insure proper contact with adhesive and remove any air bubbles.
SETTING CERAMIC TILES
Use any of the following products to install ceramic tiles over composition cork underlayment: Flexible thinset mortar, Modified epoxy mortar, 100% Solid epoxy mortar, Multipurpose mortar and Sanded thinset gauged with high strength admix. Follow product information sheets for specific instructions. To grout, use the appropriate grout for the tile type, etc. For the installation of hardwood flooring consult manufacture for the correct adhesive and specific installation instructions.
