OSB

OSB (Oriented Strand Board) is an engineered wood panel made from compressed wood strands bonded with resin. It is widely used in construction for flooring, wall sheathing, and roofing.

OSB can be used outdoors only if it is specifically rated for exterior use and properly sealed. Without protection, prolonged exposure to moisture can cause swelling and deterioration.

OSB board can tolerate limited moisture, but repeated or prolonged wetting can lead to swelling and loss of structural integrity. Proper sealing is recommended in moisture-prone areas.

Yes, OSB can be painted after applying a suitable primer and sealer. This helps reduce texture visibility and protects the board from moisture and wear.
