INSTALLATION

Use Mapei W55 adhesive to Adhere, the “groove side” of Quiet Floor to your sub floor. Allow 24-48 hours for adhesive to cure. It is recommended that another layer of marine grade or exterior grade plywood be adhered (with Mapei W55) to the “flat” or top side of the underlayment before installing the finish floor.
