Better than some of the more runny products out there, especially for waterproofing corners.

TERRIBLE product - it FAILS A FLOOD TEST! May 23, 2013
Reviewer: Jeff K from Bristol, PA  
This is the poor man's version of Hydroban - which IS a good product.

This stuff is NOT good.  I cleaned the surface thoroughly, put down 1 coat, gave it 24 hours then a 2nd coat - and that cure for a full 36 hours then did a proper flood test.  Only 24 hours later the "waterproofing" was bubbling up in places and so soft that you could rub it off with your finger.

This would have been a total disaster, had I trusted the material and the manufacturer.  Thank goodness I did a flood test.

If you really want to use a liquid, try Hydroban or Redguard.  As for me, I switched to using ONLY membranes like Wedi and Mapei.  NO leaks, reasonable prices, and very easy and fast to install.
