Love it when a plan comes together !
My Bilco outside basement doors were needing some repair of some sanding and painting. My friend told me about this product for sealing out water that was leaking in on the steps. I figured why not try it so I painted it on all the seams that the doors were sitting on. Wasn't but a day or two it got a good drenching of rain. When I opened the inside dioor to the steps I was a surprise to see absolutely no water on the steps. Worked Great!! now for the last coat of paint and they will work and look like new. Easy to use, water cleanup and paintable.

Does a great job!
This product does as advertise. Fairly easy to apply and looks great! Been on the block wall for 1 month and we have had heavy rains. NO LEAKAGE!

Stick and white
Nice and thick but still two coats. You’ll need to scoop it out of the can

Applies with airless paint sprayer
I used a graco true coat 360. Applies great. Used that tool cause it draws from a cup and didn’t have to waste material in hose line. Applied to a sub grade wall that would get damp after a really hard rain.

No more leak on slide out
I put couple coats on rv slide-out . I'm happy, no more leaks when it storms outside.
