OSI® QUAD® Advanced Formula Window, Door & Siding Sealant OSI QUAD Window, Door & Siding Sealant is an advanced formula sealant designed for superior performance on exterior window, door, siding and trim applications. OSI QUAD can be applied to wet or dry surfaces, even at freezing temperatures. And unlike other sealants, QUAD resists dirt & dust collection, yellowing and water washout. QUAD is self tooling and once cured, it is paintable. OSI color specialists work closely with leading window, door, siding and trim manufacturers to ensure perfect color matches.
OSI QUAD Advanced Formula Window, Door & Siding Sealant is specially designed for sealing around windows, doors, fiber-cement siding, vinyl siding, roofing and gutters. It bonds without a primer to most common substrates like cedar, fiberglass, aluminum, masonry and concrete.
