Ames Research Laboratories BMX5RG Blue MAX Waterproofer, Regular Use in Interior & Below-Grade Exterior Concrete Sealer and More. Liquid Rubber, 5 Gallon (Pack of 1), 640 Fl Oz

Wow, what a great coating to support my underlayment cement board. The elasticity and water proof quality provides extra added durability to the cement board. One coating is great -2 would even be better.

This served as a primer for an elastomeric coating, over a weathered modified bitumen roof. It's important that you clean the surface first with a soft wash or light pressure wash to get rid of any accumulated gunk that may block adhesion. But once you've got a dry & clean surface, this stuff sticks like, well, glue. I laid down two coats several days apart. It dried / cured fairly quickly, so I was able to walk on it after 24 hours (after each coat). Rain doesn't seem to hurt it after it's had a few hours of initial cure time. Just get it good and dry before re-coating. I'm now finish coating it with AMES Elastomeric white roof coating, with good results so far.

Used for a crack in my tub. Just ended up going over the whole thing and it works great.

Used this to waterproof a window sill in my shower, the previous owners painted it with regular water based paint. 🤦‍♀️ Needless to say, the paint eventually cracked and peeled, so the sill was in desperate need of the proper type of paint for this situation, Blue Max was perfect, I prepared the surface, and applied a few coats, it works great, and no odor, love it!!!

Seems to do what it's supposed to. Definitely stinky for a product that's non-toxic and VOC free . I don't recall red guard smelling this bad or taking this long to dry. Smell cleared up after a week or so. Also, can says it dries in 4 hours, It stayed pretty tacky/sticky and wet feeling for over 4 days after application. This was in the desert at 95 weather/5-10% humidity. Lastly, this blue does take extra coats to cover. Too bad this is the only color available without extra shipping time.

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.

Works but needs a top coat if used outdoors in the sun. Didnt know that when i bought it.

I put couple coats on rv slide-out . I'm happy, no more leaks when it storms outside.

Very good products sealed like it should. We'll by again.

Works great

Très bon produit il s’applique très bien

This product is very sticky when it dries The video says if turns grey which is a lie Never buy this product so many better cheaper options available

Got another galon to experiment with brush. Stunning luck of i formation. No word states on; Is any solvent available / what kind of if any ( it's possible to thin it with water or anything else? ) I would like to use this paint with an air spray gun- does it need a special equipment / hardware to do so?) Where is MSDS information about this chemical? I was hoping to get all of it along with the product, but NOTHING was attached to it! Taking two stars because of that.
