Westly—December 3, 2023✓ Verified purchase

Use to seal around windows and other wall penetrations on the interior of your house. Don’t use on exterior or exposed surfaces. Way better than just spray foam Read more

AirDam is a gun-grade waterproofing sealant that combines the best of silicone and polyurethane properties. This single component, Silyl-Terminated-Polymer (STP) is easy to gun and tool in all weather conditions. Installed as the interior air sealant, R-Guard AirDam creates a long lasting, weather-tight seal that prevents moist outside air from entering, and conditioned indoor air from escaping around window and door assemblies. This ensures that wind driven rain and condensed water are diverted to the flashing membrane and the water resistive barrier before it can enter the living space. Read more

like super thick caulk and Very sticky

gorsuch—January 9, 2025✓ Verified purchase

I used this to Air dam the top ridge of my shed...more as belt and suspenders and the exterior had 2 layer of waterproofing so the heavy bead was mostly cosmetic. I also used it under some trim around a window and door. I let it dry before I trimmed out the interior. It takes a lot longer to dry that chalk but that makes sense as it feels much denser.
