Magnesium oxide sheeting is essentially blast proof drywall. The problem the various producers faced was finding a coating that could adhere to the smooth glass-like finish of the board, that match the anti bacterial and flame resistance of their product. Weatherskin is the solution to their problem. Our fire-rated coating and specially designed bonding primer is built and tested to last on the modular structures and pre-fabricated buildings that are built with this amazing board.
