    OSB3 Tongue & Groove ( Oriented Strand Board ) is the roof deck of choice for laying a new fibreglass roof. It’s rough textured surface allows the resin to get a firm grip and key into the board, meaning there is very little chance of delamination ( the matting peeling away form the surface of the wood ).

    • Vigorously abrade plywood to improve bond with 40-60 grit red aluminium oxide paper
