Ames Research Laboratories AMES BMX1WRG 1 Gallon Blue Max, White Waterproofer, Regular Use in Interior & Below-Grade Exterior-Concrete Sealer, House Paint and More. Liquid Rubber

Used it for basement wall, works great. Be warned, it’s very thick.

This Prague is amazing. I use it all the time for leaky basement.

I did extensive research on the best product to water proof an interior block wall. Blue Max is amazing. Easy to apply with a small roller and the coverage is very good. I applied two good coats. I did have to open a window for a couple of days to hold the odor down. I painted over it with typical good wall paint and any lingering odor was completely gone. I purchased the Ames peel and stick tape for along the floor and I applied it to the first area...then used the Blue Max Liquid over it. On another side I did not apply the Tape and I have to say the seal was so good I did not need to use the Tape the first time. I finished my job without it...only using the Blue Max.I do not have running water through the wall, just lots of moisture. It is Springtime here in the Pacific NW and there are seeps and springs on the outside of this wall. So I did not finish off this wall for the last two months, in order to see if what I applied would actually work. It Has! The wall and floor are dry. There is no musty smell and the paint has not changed in any way. I am now ready to complete my project and turning this area into good livable dry space.

This product seem to change the moisture level right away and my basement. It was not messy or hard to use. ONE 5 gallon bucket goes along ways!

It goes on a lot different than I expected and it dries translucent. Had to do 6 coats for it to be as thick as I needed but it’s on a water trough the dogs use to swim in. So far, no issues!

Haven't used it yet but I've seen it used and man oh man it is great at waterproofing whatever it's painted on. I will use it as a primer for my travel trailer roof reseal job. And look how well it was packaged in shipment.

Impressed with the coverage and the strength of the bond. Very easy to apply.

We used this to cover the floor deck to our house prior to having it protected by walls and a roof. It protected the tongue and groove plywood from water, and water did not seep into the tongue and groove ceiling for the basement below. We used 3 coats and tarped it, sweeping rainwater off the tarp and occasionally removing the tarps so everything could breathe and dry out. We have used it on our barn decking during construction as well (see photo). No smell or harsh chemicals!
