Pre-installation checks
Before fixing, inspect the board for any visible damage or delamination. Store boards flat and off the ground in a dry, ventilated location to prevent moisture absorption and warping. Check that your supporting structure is level and properly spaced to support the 11mm thickness without excessive deflection. Confirm that fixings, adhesives, and any additional materials are compatible with structural OSB applications and meet building regulations for your specific use.
