Q:I applied Aqua-Proof Prep MD859 24 hours ago as a primer. Rate=1 gal/55 sq ft. Today there is one spot about 2 1/2 inch dia that is skinned over but is soft when pressed on. Uncured material underneath? What do you recommend? Top coat over it or wait?

      A:  Hi Paul, you can apply the Aqua-Proof Primer and then you have to topcoat. If you are going to be walking on top of it then we suggest to use tiles or type of similar walking surface.

        A:  Hi Mary, the Aqua-Proof Prep for roofs it's used as a waterproofing coating under a roof sealer system or as part of a repair system. Must be top-coated with a compatible roof coating product, applied to manufacturer specification, within five days of application to protect from UV exposure.

          This product is what it is and applied as designed. Delivery was great and the kind folks made the experience very good. I'm giving it a "good" rating because it didn't get on the roof and apply itself. :)

          The product arrived 10 days after I ordered it, even though HD.com said that it was in stock. The product arrived damaged, and I was told that I needed to wait another 8 days to get a replacement. If you need to fix your roof anytime soon, order something else off the shelf.
