Installation Instructions for DuraCork C61

Loose laid Installation
The DuraCork C61 must be installed around all the perimeter walls with the joint butted tight together using single sided carpet tape. It should be loose laid up to the gripper or previous fitted under it. In this last case, the carpet gripper is nailed onto the perimeter strip. Fit the carpet using the gripper around the edge of the room to secure the carpet and give it a neat finish. Carpet grippers are ideal for use with DuraCork C61.

Bonded Installation
Fold back one half of the underlay and using a notched trowel apply acrylic glue to the subfloor ensuring a complete coverage. Unfold the DuraCork C61 onto the area with glue and repeat this method to the other half of the underlay. Trim in the DuraCork C61 tidily around the margins. Position the carpet precisely on the underlay before any adhesive is used. Unfold the carpet onto the adhesive previously applied on the DuraCork C61 surface. Repeat this method for the other half.

Final Flooring
Always follow manufacturers recommended installation instructions.
