LePage® Quad® Window, Door & Siding Sealant

LePage QUAD Window, Door & 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 pickup. 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 & Siding Sealants are paintable with either latex or oil-based paints.
