CWC Stop Condense is a white interior coating for cold walls that condense. Latex with nanoporous minerals holds the painted surface up to 5°C warmer than an ordinary painted wall, keeping it above the dew point so condensation and mould stop forming. Rated for rooms up to 90% relative humidity, like bathrooms, kitchens, thermal bridges and uninsulated corners. Two coats by roller or brush; tintable with water-based paints. Indoor use only.

    Frequently Asked Questions

    What is C.W.C. Stop Condense used for?
    It's an interior thermal paint for cold walls, pillars and thermal bridges. It holds the surface up to 5°C warmer, so condensation and mould stop forming.

    Does it need a primer?
    No. It goes straight onto a clean, sound surface, including old paint that's still well bonded. Concrete or masonry needs to be slightly damp when you start.

    Can I seal it with Aquafloor Eco?
    No. Aquafloor Eco seals the surface at µ = 1932, and CWC Stop Condense is a highly breathable finish at µ = 8.

    Can I paint over it?
    Yes, with a breathable water-based paint like Limepaint.

    How many coats should I apply?
    Two coats, the second once the first is dry (about 6 hours at 23°C). Add a third where mould or the cold spot is severe.

    Is it waterproof?
    No. It’s a thermal paint for interior walls; water coming through a basement wall needs WATstop.
