OSIQuad Window, Door and Siding Sealant Beige 425, 10 fl oz, 1, Cartridge

Excellent quality caulking. Applies smoothly out of the gun, easy to smooth and work with excellent adhesion. High recommend.

Excellent flow and stays consistent for ease of usage. Product is some of the best on the market. Great seal and smooth final texture.

All the pipe and pvc cracks in my home. Excellent sealer.

We used this to caulk our LP smart side lap siding that we just installed on our house. We did the project in November and into December. The coldest day we caulked was 28° and it cured wonderfully. It is rated at 20° as the lowest application temperature. The cheaper stuff is only rated at 40° so it would not have cured. It is definitely a bit more difficult to work with, but it cures amazingly and if you need to caulk in cold weather, it's your best bet!!

Works as it should and Amazon had the lowest price around when I purchased the product! Price may have fluctuated by now

The caulk itself seems to be of good initial quality for the price ."Guns " easily and sticks great with minimal sag .I wouldn't want to use a large amount indoors , in an occupied area . Smell is pretty strong and probably not healthy to breath .

This product hardens to a consistency that I think caulk should be. It has a little flex, but is very tough and sticks well. It's my go to for all outside caulk jobs. It comes in a lot of colors and matches well to all of my jobs. Take a look at the OSI website to see all of the colors, then order from Amazon.

Need to be fast. It skins over in 30 minutes. Works really well.
