1. Loose lay the battens, felt side down, in continuous rows at recommended centres. Allow for perimeter battens at the ends of the batten runs. All perimeter battens must be isolated by at least 25mm from the walls.

2. When planning the floor layout leave a 10-15mm expansion gap around all perimeters, fix the flooring to the battens using a generous amount of Hush-Bond Panel Adhesive and secure with ring nails or screws. The fixings must not penetrate the resilient layer to the underside of the battens. At the same time the flooring boards should be glued at all teegee joints board to board.

3. Press Hush-Seal 20 Perimeter Seal into the perimeter expansion gap ensuring that the floor floats freely of the walls maintaining acoustic isolation or use perimeter detail as per Robust Detail instructions using Hush-RD Flanking Strip.

Skirting should be fitted a minimum of three millimeters clear of the floor surface. (PCT only).
