Bostik “PWC,” Interior & Exterior Acrylic Caulk

Bostik’s new PWC offers an advanced formula, fortified with silicone for long-lasting flexibility and excellent adhesion, ensuring a protective barrier against moisture both indoors and out. It provides a watertight seal around most building materials and common household surfaces including: trim, windows, door frames, sinks, tubs, shower surrounds, countertops, ceramic tile and natural stone.
Once cured to a smooth, satin finish, the caulk becomes mold and mildew resistant. Paintable in just a few hours, Bostik PWC is compatible with both latex and oil-based paints and complements pre-finished white trim.
Additionally, Bostik PWC is non-hazardous, non-flammable, low-VOC and meets/exceeds the specification standard for latex sealants ASTM C-834-10, Type OP, Grade -18°C.
According to Kevin Ray, Bostik’s Product Specialist, “PWC is extremely user-friendly because it is easy to clean and can quickly be applied with conventional hand or air-powered caulking equipment. Its working time, low shrinkage and superior flexible properties make it the ideal product for even the most demanding of applications.”
