Coo-Var Anti-Damp Paint Protects Interior Walls from Moisture

Manufactured by Coo-Var

Coo-Var Anti-Damp Paint is a professional, low-odour, resin-based interior primer that protects walls and ceilings from dampness, efflorescence, and moisture-related staining. Engineered with an active reagent, this specialist coating interacts with surface moisture to control its release, helping keep damp areas cleaner, brighter, and more hygienic. The included biocidal components preserve the dry film, inhibiting mould growth and preventing unsightly discolouration.

Unlike standard emulsion paints, Coo-Var Anti-Damp Paint forms a breathable, moisture-resistant barrier that escapes water vapor while preventing further damp penetration into the wall surface. It is suitable for various substrates, including plaster, cement, and stone, providing excellent adhesion even on slightly damp walls. Once fully cured, it can be overcoated with conventional interior paints to complete your decorating project.
