Drylok 27512 Latex Water Proofer, 1 Quart, White

I painted some basement walls with this stuff more than 20 years ago. They had had continual problems with mold and mildew. Washed them down with TSP and bleach and installed drylock and an overcoat of colored paint. On the whole wall there is only one 3 inch spot where efflorescence has occured and requires special treatment.Likewise painted a pump room off the basement that had been always wet and damp. Now it is dry and cool and no mold or mildew has formed on the pump surge tank since.When the directions are followed it works as advertised.

I used this product to paint and seal a 3d aquarium background made out of styrofoam after hearing recommendations from other people. The textures gives a great rocky-like look when a few layers dry and so far it has worked perfectly. I waited a week for it to fully dry and it is completely waterproof. I've had fish in the aquarium with the background for a month with no problems so it's not toxic when it dries. Get some Quikrete Cement Colors to mix with the Drylook for your desired color.

This is the best water sealer that I have found. I use this sealer to seal my outside water fountain. It's better than caulking or silicone to seal masonary material from leaking water. Because it's exposed to the AZ sunlight I have to re-seal every few years. Apply just like latex paint and cleans easily also.

The application of this product was easy, it only takes time for coverage. We had an intense rainstorm recently and Drylok did the trick.

I sealed up my basement walls from water seeping in and this paint looks good on my outside porch columns also!

This may be a good product, but sadly I paid for something I couldn’t even use this. First of all, I couldn’t find it. Lasership left it in front of the garage door instead of the front door. This easily could have been driven over. Then when I opened the box, the lid was not on the paint can, and at least half of the contents had spilled out all over the box. What a waste!

Seals beautifully. I didn't know that it was a grainy/gritty "no slip" finish. I wanted a smooth finish. So, 5 stars for effective, but minus 2 stars for not being a smooth finish.

This here stuff is just like heavy paint and concrete got together and had a Bambino. And that Bambino will plug up any reasonable leak in a concrete wall or even a floor. The water comes and looks at this stuff and just turns around and goes back.
