Description

Arm yourself against the elements with OSI Quad Window, Door & Siding Sealant. OSI Quad Window, Door & Siding Sealant is an all-season formula designed for superior performance on exterior window, door and siding applications, fiber- 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. OSI Quad bonds without a primer to most common substrates like cedar, painted or stained woods, fiberglass, vinyl, coated aluminum, steel, metal, brick, masonry and concrete. With resistance to UV and extreme temperatures (20°F to 120°F) and proven wet surface application, OSI Quad is the versatile and durable choice for professional contractors. OSI Quad is self-tooling and once cured is paintable with latex paints. Our color specialists work closely with leading window, door and siding manufacturers to ensure perfect color matches. OSI Quad is composed of elastomeric polymers and high quality synthetic resins. OSI offers an arsenal of adhesives, caulks, and outdoor construction sealants for the true professional. OSI: Tougher Than the Elements.

  • Almost a glue! Great stuff indeed!
Size: 10 fl oz
This stuff is almost a glue form of caulking, it sticks well, covers great, but once you squeeze it from the tube, don't touch it! You will be living with your mistake of touching it before it's cured for the rest of your life. but it's amazing aside from the need to be careful while applying

  • Old Favorite
Size: 10 fl oz
I've used this stuff many times for exterior projects. It is the best I have ever found. Although it is hard to smooth with a finger, it is tenacious as all get-out once it is cured, so the smoothing issue can be forgiven. It doesn't shrink much at all, so there is (in my use) none of the dreaded gap with the substrate once dried. It can be used with a much larger gap than most other caulks- specs on the product packaging can be trusted. Adherence strength is very high. Comes in many colors including black (rare) to match my trim. Also, paintable. I know of no better caulk- exterior. ... show more

  • The best
Size: 10 fl oz
Never buy any other caulk. It's hands down the best in the caulking buisness.

  • Best window and door sealant
Size: 10 fl oz
Stuff is paintable and it can be flattened with a putty knife. Easy to use. Pay the price and get great results

  • Tricky to use but done right, it's the best.
Size: 10 fl oz
Fantastic stuff for exterior applications. Used this in black color to coordinate with the trim on an RV. The stock clear silicone was giving up and peeled off readily with minimal effort. Quad will stick around much, much longer. After masking the bead line for a nice clean edge, add a bead just large enough to fill the gap. Though tooling is not recommended because of how fast it skins over, lightly feathering ensures good adhesion and a clean line. Work quickly and remove the masking as soon as possible to reduce the chances of disturbing rapidly developing skin. Product is waterproof in minutes but will stay "gooey" for many days (once it cures it's pretty much bulletproof but stays pliable for... A long time). ... show more

  • Best caulk ever!!
Size: 10 fl oz
I live right on Lake Michigan. The waves crash against my sliding glass door and windows. We had terrible flooding. This past summer we sealed everything with OSI Quad. Problem solved. No water at all inside. Really fantastic stuff. Super strong and durable. Just don't get it on your hands. It's very hard to get off. ... show more
