Cut boards to size using a fine-toothed saw or sharp knife. For floor applications, lay boards over a DPM on a clean, level substrate. Butt joints tightly and stagger in a brick-bond pattern. Tape joints with foil tape. Install a polythene slip membrane over insulation before screeding. For wall and roof applications, fix mechanically or adhesively as appropriate. Refer to manufacturer guidance for specific application details.
