Coo-Var Anti-Condensation Paint is a professional-grade condensation control coating designed to prevent condensation from forming on cold surfaces, eliminating the black mould, ceiling drips, and damp patches that occur in bathrooms, kitchens, bedrooms, and poorly ventilated spaces. Unlike standard emulsions that simply cover mould temporarily, this specialist coating stops condensation at the source by creating a protective insulating layer that prevents moisture from condensing.

Particularly effective on metal interior roofs where condensation causes constant dripping and water damage. Metal surfaces are especially prone to condensation because they conduct cold temperatures rapidly, causing warm air to condense into droplets. Coo-Var Anti-Condensation Paint creates an insulating barrier on metal roofs, preventing drips and eliminating the water damage, rust, and mould growth that occurs in garages, workshops, sheds, and industrial units with metal roofing.

Developed by Coo-Var with over 100 years of British coating expertise, this anti-condensation paint is the professional solution for condensation control, mould prevention, and creating dry, healthy indoor environments. The water-based acrylic formulation contains specialist particles that create a slight textured finish, which is essential for the insulating layer that prevents moisture from condensing on treated surfaces.

When warm, moisture-laden air meets cold surfaces (walls, ceilings, metal roofs, windows), it cools rapidly and releases moisture as condensation. This creates drips, damp patches, and the perfect environment for black mould growth. Coo-Var Anti-Condensation Paint's specialist formulation prevents condensation from forming by creating an insulating barrier that keeps surfaces warmer, eliminating the conditions that cause mould and drips.

The formulation includes biocidal protection to prevent mould and mildew growth on treated surfaces, making it ideal for high-humidity areas like bathrooms, kitchens, utility rooms, and bedrooms with poor ventilation. It creates a dry, drip-free matt white finish with a slight texture that stays cleaner and healthier for longer.

Suitable for interior walls, ceilings, and metal roofs on plaster, cement, brick, metal, and previously painted surfaces affected by condensation, mould, or drips. Apply 2 coats for best results, allow to cure, then enjoy a dry, mould-free environment. Can be topcoated with emulsion or left as a standalone matt white finish (the slight texture will remain but can be covered with decorative finishes).

What is Coo-Var Anti-Condensation Paint and when should I use it?

Coo-Var Anti-Condensation Paint is a professional-grade condensation control coating that prevents condensation from forming on cold surfaces, eliminating black mould, ceiling drips, and damp patches. Use it in bathrooms, kitchens, bedrooms, metal interior roofs, and poorly ventilated spaces where condensation causes mould growth and dripping ceilings.

How does anti-condensation paint work?

Anti-condensation paint contains specialist particles that create an insulating layer, reducing the temperature difference between warm air and cold surfaces. When surfaces are warmer, moisture in the air doesn't condense into droplets. This prevents drips, damp patches, and the conditions that cause black mould growth.

Does Coo-Var Anti-Condensation Paint stop damp?

No, this paint prevents condensation (moisture from warm air condensing on cold surfaces), not rising damp, penetrating damp, or water ingress from leaks. If you have structural damp issues, you must address the source (fix leaks, install damp-proofing, improve drainage) before painting.

Does Coo-Var Anti-Condensation Paint create a textured finish?

Yes, Coo-Var Anti-Condensation Paint creates a matt white finish with a slight texture. This texture is caused by the specialist particles that create the insulating layer, which is essential for preventing condensation. The texture is barely noticeable but functional. If you prefer a completely smooth finish, you can topcoat with emulsion after 4 hours (the insulating layer will continue to work underneath).

Can I use Coo-Var Anti-Condensation Paint on metal interior roofs?

Yes, Coo-Var Anti-Condensation Paint is ideal for metal interior roofs in garages, workshops, sheds, and industrial units where condensation causes dripping and water damage. Metal surfaces are especially prone to condensation because they conduct cold temperatures rapidly. The insulating layer prevents moisture from condensing on metal roofs, eliminating drips, rust, and water damage. For bare metal, prime with SPO All Metals Primer first. For previously painted metal, ensure coating is sound and well-adhered.

Do I need to prime bare metal before applying Coo-Var Anti-Condensation Paint?

Yes, for bare metal surfaces (unpainted metal roofs, ceilings, or walls), you must prime with SPO All Metals Primer first. This ensures optimal adhesion, prevents rust, and creates a stable base for the anti-condensation coating. Allow the primer to dry completely before applying Coo-Var Anti-Condensation Paint. For previously painted metal, ensure the existing coating is sound and well-adhered.

Can I use Coo-Var Anti-Condensation Paint in bathrooms and kitchens?

Yes, Coo-Var Anti-Condensation Paint is ideal for bathrooms, shower rooms, kitchens, and utility rooms where condensation causes mould and drips. The condensation control coating prevents moisture from condensing on walls and ceilings, whilst the biocidal protection prevents mould growth. You cannot apply to areas that are exposed to constant water like the walls of a shower enclosure.

Do I need to remove mould before applying anti-condensation paint?

Yes, you must treat and remove existing mould with Fluxaf Mould and Mildew Remover before painting. The paint prevents new mould from forming, but it will not remove existing mould. Clean the surface thoroughly and allow to dry completely before application.

How many coats of Coo-Var Anti-Condensation Paint do I need?

For severe condensation areas (bathrooms, shower rooms, kitchens, metal roofs), apply 2 coats for complete insulation and condensation prevention. For lightly affected areas (bedrooms, living rooms), 1 coat may be sufficient. Allow minimum 4 hours between coats.

How long does Coo-Var Anti-Condensation Paint take to dry?

Touch dry in 2 hours, hard dry in 4 hours at 20°C. Allow minimum 4 hours before recoating. Wait 24 hours before exposing to moisture or steam (e.g., hot showers). Full cure is 24 hours. Drying times may be extended in cooler temperatures or high humidity.

Can I topcoat Coo-Var Anti-Condensation Paint with emulsion?

Yes, you can topcoat with emulsion or vinyl matt after 4 hours if you want a decorative colour. Coo-Var Anti-Condensation Paint can also be used as a standalone matt white finish. Two coats of top coat typically required for full coverage. The slight texture will remain but can be covered with decorative finishes.

Will anti-condensation paint stop my bathroom ceiling from dripping?

Yes, Coo-Var Anti-Condensation Paint prevents moisture from condensing into droplets on ceilings. The insulating layer keeps the ceiling warmer, preventing condensation from forming and eliminating drips, damp patches, and water marks.

Is Coo-Var Anti-Condensation Paint safe to use indoors?

Yes, Coo-Var Anti-Condensation Paint is a water-based acrylic coating with low VOC content (≤ 30 g/L) and is safe to use in occupied indoor spaces. Ensure good ventilation during application and drying. Touch dry in 2 hours means rooms can be used quickly.

How much coverage can I expect from Coo-Var Anti-Condensation Paint?

Coo-Var Anti-Condensation Paint provides approximately 8–10 m² per litre per coat on smooth surfaces. A 500ml tin covers 4–5 m², a 1L tin covers 8–10 m², and a 2.5L tin covers 20–25 m². Porous or textured surfaces may reduce coverage. We recommend ordering 10–15% extra for surface variation and touch-ups.

Does Coo-Var Anti-Condensation Paint prevent mould growth?

Yes, Coo-Var Anti-Condensation Paint contains biocidal protection to prevent mould and mildew growth on treated surfaces. The insulating properties prevent condensation from forming, eliminating the damp conditions that cause mould. However, you must treat existing mould with Fluxaf Mould and Mildew Remover before painting.

Will anti-condensation paint work if I have poor ventilation?

Anti-condensation paint prevents moisture from condensing on cold surfaces, but it works best when combined with improved ventilation. Open windows, use extractor fans, and improve airflow where possible to reduce overall moisture levels. The paint prevents condensation, but good ventilation reduces the amount of moisture in the air.

What products do I need to complete my anti-condensation treatment?

We recommend using SPO All Metals Primer for bare metal surfaces, Fluxaf Mould and Mildew Remover to treat and remove existing mould before painting, and professional Brushes, Rollers and Trays for application. These products ensure the best results and proper surface preparation for long-lasting condensation control.
