APC Cork Cork Flooring Underlayment

Cork Flooring Underlayment

Cork underlay is a cost-effective solution for reducing airborne and impact noise problems. Due to the unique 40 million cells per cubic centimeter honeycomb structure of cork and the special nature of the resin binder, it performs outstandingly under floating and laminated floors, wooden floors, ceramic tiles, natural stone, linoleum, and vinyl floors. During the cork agglomeration process, an antibacterial additive (Microban®) is added to deliver continuous antibacterial and antifungal protection and contribute significantly to the acoustic performance of floors improving environmental comfort.

APPLICATION OF CORK to SUBSTRATE
Apply cork adhesive according to the 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 ensure proper contact with the adhesive and remove any air bubbles.

SETTING CERAMIC TILES
Use any of the following products to install ceramic tiles over composition cork underlayment: Flexible thin-set mortar, Modified epoxy mortar, 100% Solid epoxy mortar, Multipurpose mortar and Sanded thin-set 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.
