Basic waterproof floor coating addresses common moisture problems in below‑grade and slab‑on‑grade concrete where groundwater vapor migrates upward, causing adhesive failure, tile lifting, mold odors, and surface dusting. Water‑based epoxy or acrylic sealers penetrate slightly then form a thin protective skin that reduces vapor transmission rates to acceptable levels for most flooring toppings.
Unlike heavy‑duty systems, basic coatings prioritize cost‑effectiveness and ease of application over extreme chemical or mechanical resistance. They handle occasional spills, routine cleaning, and residential foot traffic while blocking the majority of moisture vapor that causes problems. Two or three thin coats build cumulative protection without the thickness that traps moisture beneath.
Preparation focuses on cleanliness rather than heavy profiling: degreasing, pressure washing, and etching ensure good bite. Neutral primers address alkalinity and pH issues common in new concrete. The result withstands household cleaners and provides a clean base for tiles, vinyl, or carpet.
