LePage QUAD® window, door and siding sealant is composed of elastomeric polymers and high-quality synthetic resins. This product offers the superior adhesion characteristics and unmatched elasticity found in high-performance sealants. It yields a tough, rubbery seal which resists outdoor weather related elements like water, oxygen, ozone, heat and UV light. The formula skins over in a short time to resist dirt and dust pick up. It goes on smoothly and has easy cut off without stringing. When cured, the surface displays a slight sheen similar to some silicone sealants. QUAD® window, door and siding sealants are paintable with either latex or oil-based paints.
