We used it on our basement walls and about 2 inches of the floor where is met the walls. We used about 6 coats. It went on very easy. I would use it on a floor if I were coating it with some other layer- seeing as it is tacky and even when dry it is still rubbery in a way that would not be easy to sweep. **Q: Can you paint over this? How about applying stucco finish over it?** A: i,m not sure if you can paint over it,i didn,t have good luck with this product,applied over concrete wouldn,t stick,water leaked right through. **Q: Can you use this for a liner of a stock tank that I turned into a swimming pool? And does it feel like rubber on your skin?** A: It's noy recommended for use in pools but we have had customers do it. It does end up with somewhat of a rubbery feel. If you do use it, keep in mind everything above the waterline must be top coated because it is UV sensitive. **Q: does this product work well on brick? -- I have seepage in a basement that has brick wall (seepage is not to bad)** A: Yes, it will adhere to brick just fine. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Review *by A***T on 9 February 2026* I actually used this to seal my subfloors after attempting to neutralize pet stains. The stains were the worst! This product is amazing, easy to use, very easy to clean up. Would use 10 out of 10 for any waterproofing need. ### ⭐⭐⭐⭐⭐ Review *by J***E on 1 April 2026* Good stuff can’t go wrong here easy to apply more than one way to do it ### ⭐⭐⭐⭐⭐ Review *by G***Y on 1 August 2025* You are not going to believe how I used this product. I build a whole water tank just with the product. No mortar used. Nice and thick but no pasty. Application easy I used ketchup bottles to spread. I used 2 of them on a cabin roof and painted over for water proofing. If you are DIY. You need this. This is my 8 bucket order. ## Frequently Bought Together - Ames Research Laboratories BMX5RG Blue MAX Waterproofer, Regular Use in Interior & Below-Grade Exterior Concrete Sealer and More.
