Arm yourself against the elements with LePage QUAD Invisible Window, Door & Siding Sealant. LePage QUAD Invisible Window, Door & Siding Sealant is an all-season formula designed for superior performance on exterior window, door and siding applications, fibre-cement and vinyl siding, PVC trim, and much more. It can be applied to wet or dry surfaces, even at freezing temperatures and, unlike other sealants, it resists dirt and dust collection, yellowing and water washout. LePage QUAD bonds without a primer to most common substrates like cedar, painted or stained woods, fibreglass, vinyl, coated aluminum, steel, metal, brick, masonry and concrete. With resistance to UV and extreme temperatures (-7°C to 38°C) and proven wet surface application, LePage QUAD is the versatile and durable choice for professional contractors. LePage QUAD is self-tooling and once cured is paintable with latex paints. When cured, this invisible sealant displays a slight sheen that’s similar to silicone. LePage offers an arsenal of adhesives, caulks, and outdoor construction sealants for the true professional. LePage Works. Period.
