Great product


Great product. The smell is not as bad as some competing brand products. I used a small roller to apply and it dried very fast. You will have maybe 30 seconds to do this from the first brush stroke before it starts to dry. Overall, it's a great product and I'm confident it will hold up.



This stuff is amazing. Two coats on your backer board and you are done. Smells better than the red stuff. Only downside is it hard to see any lines.

Will compete with Hydroban and Red Guard


Used this stuff for years for showers as well as crack isolation on floor.
