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

This is great stuff. I have repainted my stock tank pool with it works great. One thing to note is that this is not like regular paint more of a consistency of runny snott. But does a great job water proofing over a primer also the white takes usniversal pigment really well. I added blue to it so i would have a light blue inside to my stock take pool.

Happy with initial application of this product on interior lower garage wall concrete foundation . It’s only been on for a week , but, so far, it is as advertised

A great waterproofer. I purchased this item as part of a system designed to repair my leaky metal roof. Two roofers tried to repair it and failed. I sent photos of my roof to Ames Research, and their customer support department advised me on what to purchase. The product instructions were clear and easy to follow. It's fixed once and for all now.

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.

worked great for me so far so good.

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.

It done good! It wasn’t what I thought it was!
