Customer Questions & Answers


aftet the floor is painted and cured what can i clean the floor with and how?
Asked by: dave
Hi Dave, You can actually just use soap and water to clean this paint, however it's not designed for use on floors. If you need a waterproofer for your basement floor due to hydrostatic pressure, none of our products would be recommended. If you just need a floor paint, try our 1 Part Epoxy: Best of luck with your project!

Will this work on a cellar whose interior has a three-part stucco concrete surface

My cellar was installed sometime in the 1960's. I was questioning another company about their product and was told theirs would not work on a three-part stucco surface that used tar paper as its second layer. In fact, I felt like this company was trying to talk me out of using their product at all as they told me flat out that they wouldn't stand behind it. "Nuff said, I'll look elsewhere." I also need information as to what will work on the floor of the cellar as it does appear to be fully concrete and also seems to be responsible for a lot of my seepage problem. . Considering that my floor will be wet because it is accessed from outside, I need something that won't be super slick when wet. Will this adhere to hydraulic cement patching? How much of it do I have to buy to cover a 10 x 12 cellar area for the walls, and for the floors of the other product.

Hello and thank you for your question. The BEHR PREMIUM® Basement & Masonry Waterproofer can be used on properly prepared stucco. We unfortunately do not make any product for use on basement floors. Be sure to follow all back label instructions and best of luck on your project.

Do I need to use a primer with this or can I put this straight on the cinder blocks?

Asked by: DIYcrazy
Hello DIYcrazy, Thanks for your question. For below grade, this product can go directly on the cinder block without primer, and for above grade we'd recommend using a primer like our No. 436 Multi-Surface Primer & Sealer. Please follow all label instructions for best results. Well wishes for your project!

Rated 5 out of 5 by from Best Basement Paint This paint is great because it goes on smoothly and covers well.

Rated 5 out of 5 by from Excellent Easy Coverage, Minimal Smell My husband and I purchased this to basement waterproofer to coat the walls in our home built in 1978. Unlike previous experiences in other homes using Drylock, this Behr had a very minimal smell making it much easier to do this project on our own. When purchasing this, the gentlemen at Home Depot noted that the price difference between this and Drylock was minimal, but that the Behr quality was much superior. He noted that Drylock hasn't updated their formula in the last 30 years and that Behr has much better technology. I couldn't agree more. We were really impressed with the ability to tint the color of the Behr paint and ended up going with a nice shade of light grey. The application of the paint was easy and the coverage was great. The can noted that you could apply it to slightly moist surfaces which was a relief because we did have a small area were the cinderblock was already moist. We applied two coats and wow, what an improvement over the bland cinderblock! I would definitely recommend to anyone that has a moist basement. [This review was collected as part of a promotion.]

Rated 5 out of 5 by from Excellent performance and easy application! We purchased an older home with a leaky basement, and have tried a few different products to seal the walls. One waterproofing paint was so thick and sticky it was like painting with thick maple syrup. The second one didn't cover well and the smell was awful. I started to think we were going to have to hire a contractor if we were ever going to have a dry basement. After some serious frustration and quite a bit of money spent, we tried the Behr waterproofer. What a difference! The paint went on smoothly without any drag at all, even over some rough areas where the wall had been textured with sand. The coverage was great. It has been on the walls for a couple of months now and no water or moisture yet! Very pleased! [This review was collected as part of a promotion.]

Rated 4 out of 5 by from Great but very thick I have used this in several areas. It worked great in an underground basement, although it took 6 coats to finally stop the water penetration. I have also used it to paint my stucco home. The material went on quite easily and with 2 coats, it looks like new several years out. The biggest challenge is that it is really thick, think frosting and you get the idea, particularly on a cold morning. Don't try to stir it to mix in the pigment, you will be all day. Every day I was planning to paint, I took it to my local home depot to shake it. Never had a problem that way. It is really hard to roll on and I couldn't imagine spraying it, even though the directions say you can. I used a brush, which took a long time, but it seems very durable so it was effort well spent. I have also used this on wood and it works but it takes several coats, since wood is porous. But once I was done, it was really water proof and looked great. Finally, the custom color selection is pretty extensive, but don't expect every possibility. Deep colors are just not possible and the finish is totally matte, but very smooth to the touch.

Rated 5 out of 5 by from Best thing we've found! We were at our wits' end when we came across BEHR PREMIUM® Basement & Masonry Waterproofer. We seriously couldn't have found a better product! Our tiny cracks in the foundation were seeping water every time we had a bad storm and this totally did the trick! We can't thank you enough, BEHR!

Rated 5 out of 5 by from Great paint exceeded my expections!!! My daughter purchased her first home, and the garage walls showed some mold and effervescent. We cleaned the walls, read all the reviews on several companies. I had previously used another product to prevent water from entering my home. So I was surprised at the lack of odor. We picked almond cream. It took two coats, the color was great. The coverage was great. One tip I would say is to work the roller lightly, until the paint is applied, use more pressure when the roller is emptied, working the paint into the holes. Use a full roller to go over areas not completed covered. applied with a full roller. The garage is 14 feet high, I used an extension on the roller, and never climb a ladder. Covered wall great. It has only been up for day, but it looks wonderful. I would not hesitate to recommend this product. Second coat was done in half the time of the first coat.

Rated 5 out of 5 by from Changed my dark moist basement into a usable space I love this product. I was hoping to clean up the basement and make it less damp but I was suprised to find that it made it dry. Although the prep time was very long and tedious, it was well worth it. My preping properly which included regrouting lots of the mortar between the bricks, it was well worth it to do it right. I now have a very usable dry basement that I don't fear to go into!
