AMESBMX1RG 1 Gallon Blue Max Regular Liquid Rubber Waterproofer, Blue Liquid Rubber Waterproofer Interior and Exterior

Great liquid rubber...coated my wishing well bottom to hold water...

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.

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

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

Going to give this 4-stars. I'm using it to seal a cave I put in my shower to accommodate a soap insert in the wall. For my purposes it works. This product feels like liquid rubber in the can, but when you apply it, it thins and some of your brush/roller will wipe some of it away. You can probably get a true membrane with a sprayer, but I do not see this thick pasty stuff spraying well. As for brushing and rolling, it will work, but you will need about three coats, with the stroke of each coat 90-degrees to the prior coat, in order to get a truly sealed membrane. I would also not recommend using this as a final coat on an outside wall, as I can see peeling as a potential problem. When it comes to leaky walls, including basement walls, I have always done the following (it's expensive and a lot of work, but the only way to assure the leak stays on the outside): 1. Seal cracks on the outside wall with water plug cement and coat with tar when dry. 2. Seal the cracks on the inside wall with water plug cement. 3. Apply a coat of thinset and screw in cement board over the wall. 4. Fill cracks between cement board sheets with thinset. 5. Apply a coat of thinset to the cement board and finish with ceramic tile. 6. Grout tile. If I were to do it again, then I can see this product being used as extra protection by sealing the wall before step 3 and sealing the cement board before step 5.

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!

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

Love the product this is my third 5 gallon purchase. It does not help your package and product when the deliverer drops the box from his shoulder directly to the ground, while i was approaching the gate. This Side up means up not end up sideways after dropping the box from that high up.
