Choose the right sealant
Wood shrinks. Buildings can settle. In some areas of the country, buildings are designed for seismic situations. That is why we formulated WF300 Firestop Caulk. During installation, the product is great for overhead applications and offers adhesion to wood and gypsum. Once dry, it forms a flexible membrane that can accommodate various building movements. Any gaps or voids that may develop due to excessive shrinkage or building settlement can be accommodated under fire exposure conditions
