5. 70-115 moisture barricade 6mil plastic can be used in conjunction with cork
underlayment over concrete slabs for floating applications of engineered wood and
laminate flooring products.
PERIMETER ISOLATION STRIP: TO IMPROVE ACOUSTICAL PROPERTIES
1. Keep hard surface flooring material from direct contact with walls, cabinets, columns
and other fixed vertical objects for optimal acoustic insulation performance.
2. Using a utility knife with a sharp blade and a straight edge, cut the cork into long strips
approximately 1” wide.
3. Install strips vertically around the entire perimeter of the install and any fixed objects.
Adhere or tack to the wall for positioning.
4. Trim the Perimeter Isolation Barrier flush with the surface of the finished floor.
5. Prior to the installation of any base or trim, apply non-hardening acoustical grade
sealant on the top edge of the trimmed Isolation Barrier.
ELECTRICAL HEATING SYSTEM
It is important to read and follow the Electrical Heating Systems Manufacturers Instructions
COMPLETELY with regard to the installation of and the connection of the system to the
Electrical System of the building.
1. When fastening any clips or retaining devices for the wire heating system, it may be
necessary to use a mechanical fastener that will fully penetrate the CORK product and
go into the subfloor. Please follow the heating system manufacturer’s instructions with
regard to their fastening requirements.
2. Be sure to perform any connectivity testing prior to the installation of the finished
flooring.
INSTALLATION of CORK: CERAMIC TILE
1. Cut the Natural Cork sheet or roll to the desired length and loose lay directly over the
substrate starting in a corner of the room. Butt the cork against the perimeter isolation
barrier.
2. Place the end crown of the rolled material down. Any temporary end curl of the rolled
material will easily flatten out, once fully installed.
3. Pull back on half of the length of the loose laid cork and apply adhesive to the subfloor,
using either a 3/32”x3/32” or 1/8”x 1/8” V or U notched trowel.
4. For ceramic tile installations, use Roberts 7250 Premium Adhesive or a Type I Ceramic
Tile Mastic or polymer modified thinset mortar compliant to ANSI A136.1 as the bonding
