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

My Bilco outside basement doors were needing some repair of some sanding and painting. My friend told me about this product for sealing out water that was leaking in on the steps. I figured why not try it so I painted it on all the seams that the doors were sitting on. Wasn't but a day or two it got a good drenching of rain. When I opened the inside dioor to the steps I was a surprise to see absolutely no water on the steps. Worked Great!! now for the last coat of paint and they will work and look like new. Easy to use, water cleanup and paintable.

This product does as advertise. Fairly easy to apply and looks great! Been on the block wall for 1 month and we have had heavy rains. NO LEAKAGE!

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.

Nice and thick but still two coats. You’ll need to scoop it out of the can

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 used a graco true coat 360. Applies great. Used that tool cause it draws from a cup and didn’t have to waste material in hose line. Applied to a sub grade wall that would get damp after a really hard rain.

I've use this ames brand for years on my florida aluminum roof. It keeps the water out of cracks and it has lasted over 6 years and it's just now starting to need a refresh coat. I also use it to applied to concrete and aluminum joints and it sticks great, just be sure to use multiple coats following products recommendations. Its expensive, but you get what you pay for. I have used different brands from hardware stores to be only disappointed in quality and lifetime of products. Using ames is one coating you will not be worried about not fulfilling it's capabilities. I recommend using rubber gloves when working with this product because it sticks like it's supposed to.

They advertised, that it was good for a cattle troff then they said it wasn't, when I got it all finished ,also saying it's not good in the heat,it basically, Now has a rash inside the entire trough witch is 309 gallons Anyway, worthless waste of time money,now it's gonna cost more time and money to redo the entire thing,I wouldn't have Not Used this product otherwise
