Questions & Answers

Can I use this to seal and waterproof granite grip?
ByJun 30, 2026
1 Answer | 
Answer This Question

Hi Lorena, thanks for your question. No, our Basement & Masonry Waterproofer DryPlus coating is not recommended to be applied over our Granite Grip coating, and it’s also not recommended for horizontal surfaces. Instead, I can suggest checking out our Wetook Sealer or our Low-Lustre Sealer. These water-based sealers will waterproof, protect, and enhance the look of your existing coating while providing a low-luster or high-gloss finish. Have a great day! -Angie

    Answer This Question

    Hi Maria, thank you for your question. The Basement and Masonry Waterproofer is not a floor paint, and should not be applied to a humid floor. I suggest checking with your local store for a recommendation on a suitable product you may be able to use for your project. Have a great day! -Giovanna

        Can this paint also be used on steel beams? Or do I need to prime the beams first with an oil based paint?
        ByMay 14, 2026

        Answer This Question

        Hi Amap, thanks for your questions. We don't recommend using our Dry Plus Waterproofing Paint on a steel surface. Also, it's best to apply this product to a bare surface; otherwise, it may not provide the waterproofing benefit. I'd recommend finding an alternative product for your steel beam project. Have a great day! -Christina

                  Impressive coverage, low odor, nice color
                  First of all, this paint is very heavy! I'm a very petite woman and didn't think 5 gallons would be quite that heavy. (You may want to buy it by the gallon unless you are fairly strong!) I have a 100 year old home with an historically wet basement, but the water issues were remediated with the installation of perimeter drainage system and multiple pumps. This paint was applied to simply reduce moisture transfer and to look nicer. I had very stained walls which were well cleaned prior to application, but even just the first coat of this paint completely covered the stains! I still did a second coat and it was much easier to apply. I was impressed that the paint is very low odor. I have asthma and i hate working around smelly paint but this barely was any issue. I am very happy with the final job and it was worth the effort. It dries very quickly as well, maybe partly because i run a dehumidifier in my basement, but in any case that was a plus. I am adding some before/after images of the worst parts of my basement walls.

                    Nice coverage for bare concrete with 2-coats. Sadly, the pitted walls pretty much ate the thick paint up. Time will tell about the moisture proofing, but my walls are dry to begin with. Nice color options. My basement safety and storage room looks great and more welcoming.

                    Several years ago I sectioned one half of the basement to build a workshop area. I used this paint on the concrete floor. It worked well to seal the floor as well as to make cleaning the floor easier. I recently decided to refinish the other half the basement and used the same paint. I like the fact that one coat is all that is needed.

                    The paint was awesome for my situation (sealing a retaining wall). It was quite thick and ended up with a flat finish. There was no seepage through the wall later after a very heavy rain. I removed a star because of the color. The color was such a bright white that I suspect no tint was added to the base color. Will not buy paint again online because of the color issue.

                    The paint goes on very well. Easy to manage and easy to clean up. Very disappointed in the color, it says POWER gray which actually it should be called wimpy Gray. Other than that the paint did Cover pretty close to the square footage it said it would. I put 2 coats on, I'll have to wait and see how it handles the moisture.
