Customer Reviews for OSI QUAD Advanced Formula 10 fl. oz. Brown #285 Exterior Window, Door, and Siding Sealant (12-Pack)

This stuff is super hard to use but is excellent. I use this sealant in hard to get to places or places I know will be extra exposed to the elements. I find it impossible to apply it without tooling it so I do so by dipping my finger in mineral spirits and smoothing out the bead.

Works like it should

Master electrician and I've done numerous other construction projects. Purchased two tubes, used about 1/8 of it, closed it up and taped the tube end. Went to use it a few weeks later and the stuff ABSOLUTELY would NOT come out of the gun. I think it bent my caulking gun. The instructions say it has a two year shelf life but NOWHERE on the tube does it give you a USE BY DATE They printed THEIR CODE on the bottom Z3133 53. What MIGHT have been the date code has now wiped out by plunger.

does the job--spreads easily in the color I wanted

Excellent sealant if surfaces are clean and prepped.

Easy to use and long lasting

Great sealant fast shipping.

Sticks well. Cutting after drying is easy.

GOOD STUFF EASY TO USE

Purchased for sealing the cracks developed around the exterior of the window over time. Worked well.

Probably the best all around caulk I've used. On clean surfaces it adheres extremely well and remains flexible for a long time.

Excellent caulking for exterior windows, very thick, viscous consistency makes it way easier to work with. Perfect color match to bronze Anderson renewal windows, ( it’s what the company used when windows were installed) It works well for larger gaps, you do not “tool” it or use your finger to spread or flatten, it just seats itself and ends up more like a rubber seal. I poked the interior of the tube first & it worked (a couple people said the “inner breakaway seal” didn’t easily open & pressure built up in the caulking gun.) This caulk lasted 10 years the first time, then became slightly loose on edges & faded slightly. This caulk is well worth it, it was easy to apply & looks professional/ neat. I’d buy it again & recommend it to a friend.
