Cures quickly; bonds with brick, plastic, & wood.

Would Recommend

Unlike some other products, this sealant is easy to work with which results in minimal mess. It also dries quickly and adheres to multiple surfaces, and performed very well when resealing the seamed areas around our garage door.

Let's caulk about water sealants that work!

Would Recommend

This is the best concrete caulk...no more water coming in where the walls meet the basement floor. Just one smooth line and done! Dries ready to paint. Easy clean up. Loved it!
