How masonry paints, cement-based coatings, penetrating sealers and epoxy floor coatings differ in what they do and where they work.
Coatings and sealers are sold in every home store, and the labels promise a lot. Masonry waterproofing paint forms a thick film on a wall. Cement-based coatings are applied like a slurry and bond to concrete and block. Penetrating sealers soak into the surface and repel water without forming a film. Epoxy coatings protect floors. Each has a place, and none replaces drainage when water is pressing on a wall.
In many Nashville basements, a coating is a finishing step after drainage and repairs, not the first step. Painting over a wet wall can trap water and cause blistering. Using a film-forming sealer on a wall that needs to breathe can do the same. We explain how to match the product to the surface and the moisture, and we are happy to tell you when a coating is not the answer.
A thick film for dry or damp walls with light seepage.
A slurry that bonds to masonry and resists water.
Soaks in, repels water and lets vapor out.
Protects floors from stains and some moisture.
Clean, sound, bare surfaces are key to bonding.
Coatings do not replace drainage under pressure.

Paints are easy, but good preparation matters for any coating.
Usually not. Old paint often has to be removed so the new product can bond.
