Extreme 5 Gal. Bright White Flat Latex Interior/Exterior Basement Masonry and Concrete Sealer Waterproofer

Yes, this product can be applied using a paint sprayer. It can also be applied with a brush or roller.

For applying DRYLOK Extreme, a roller with a thick nap is generally recommended. A 3/4 inch or 1 inch nap roller made of a synthetic blend or lambswool is ideal. This type of roller helps to push the thick waterproofing paint into the pores and irregularities of masonry surfaces like concrete, cinder blocks, and stucco, ensuring good coverage and adhesion.

For a latex-based masonry waterproofer like DRYLOK Extreme, it is generally recommended to use a high-quality acrylic latex caulk with silicone. This type of caulk is typically paintable and offers good adhesion and flexibility, making it compatible with the DRYLOK product. Ensure the caulk is fully cured before applying the waterproofer over it.

DRYLOK Extreme is designed for masonry surfaces such as concrete, cinder blocks, stucco, and brick. It is not recommended for use on plywood subfloors.

DRYLOK Extreme is primarily designed for application on bare masonry surfaces such as concrete, cinder blocks, stucco, and brick. When applying it over a previously semi-gloss painted basement wall, proper surface preparation is crucial to ensure adequate adhesion and the waterproofing effectiveness of the product. To prepare a semi-gloss painted surface for a new coating like DRYLOK, you generally need to: Clean the surface: Ensure the wall is free of dirt, dust, grease, and any loose or peeling paint. Dull the sheen: Semi-gloss paint has a smooth, somewhat slick finish. For better adhesion, the surface should be dulled by light sanding or by using a liquid deglosser. Consider priming: Depending on the specific recommendations for DRYLOK, a specialized primer designed for adhesion to glossy surfaces might be necessary before applying the waterproofer. For definitive guidance on applying DRYLOK Extreme over previously painted surfaces, it is highly recommended to consult the product's "Use and Care Manual." This manual will provide specific instructions and recommendations for surface preparation and application in such scenarios.

Joseph, DRYLOK Extreme is not recommended for floors. The only DRYLOK Waterproofer that is effective on floors is the DRYLOK Floor and Wall. Because DRYLOK Extreme is made of a softer resin, therefore it will not hold up to foot traffic.

While the product description mentions its use on basement walls, foundations, and other masonry surfaces, it doesn't specifically say whether it can be used on basement floors. I recommend checking the product's "Use and Care Manual" for definitive guidance.
