Coo-Var Anti-Damp Paint - Paint Damp Walls Without Peeling | Interior Damp-Tolerant Paint

• Paint walls or ceilings that are damp or recovering from leaks without waiting for complete drying

• Prevent peeling and flaking when decorating damp-affected walls where standard emulsions fail

• Work on leak recovery, flood damage, or emergency redecoration projects with tight deadlines

• Decorate damp basements, cellars, or damp-prone areas where moisture is present in the substrate

• Seal efflorescence (white crystalline salt deposits) and water marks on damp surfaces before decorating

• Use an oil-based paint that adheres to damp plaster, cement, stone, and brick where water-based paints peel

• Apply biocidal protection to prevent mould and mildew growth on damp-affected surfaces

• Use as a standalone matt white finish or overcoat with emulsion or oil-based top coat for decorative colours

• Block, seal, or waterproof moisture sources (this paint adheres to damp surfaces but does not stop damp or prevent moisture ingress)

• Achieve fast touch-dry times under 2 hours (this requires 8 hours touch dry—use SPO Anti-Damp Paint for 2-hour touch dry)

• Treat exterior walls or facades (this is for interior use only—consult our experts for exterior-grade damp solutions)

• Solve the underlying source of damp (this paint tolerates damp but does not fix rising damp, leaks, or condensation issues)

• Apply to dripping wet or saturated surfaces (surface should be damp to the touch but stable, not dripping wet or with standing water)

Coo-Var Anti-Damp Paint is a specialist oil-based paint designed to adhere to damp surfaces, preventing the flaking and peeling that occurs when decorating walls and ceilings affected by damp or recovering from leaks. Unlike standard emulsions that fail on damp substrates, this oil-based formulation bonds to wet plaster, cement, stone, and brick, allowing you to decorate without waiting weeks for surfaces to dry completely.

Developed by Coo-Var with over 100 years of British coating expertise, this damp-tolerant paint is the professional solution for decorating walls suffering from damp, leak recovery, flood-damaged surfaces, and emergency redecorations where time is critical. The oil-based chemistry adheres to damp surfaces where water-based paints peel and flake, providing a stable coating that withstands moisture without compromising adhesion.

When walls are affected by damp, condensation, leaks, or flood damage, standard emulsions build up pressure behind the coating as moisture tries to escape, causing peeling and flaking. Coo-Var Anti-Damp Paint's oil-based formulation adheres to damp substrates and tolerates moisture, preventing paint failure whilst the wall continues to dry naturally.

The formulation includes biocidal protection to prevent mould and mildew growth on treated surfaces, making it ideal for damp-prone areas like basements, cellars, bathrooms, and kitchens. It also seals efflorescence (white crystalline salt deposits) and water marks, preventing them from bleeding through the coating.

Suitable for interior walls and ceilings on plaster, cement, stone, brick, and other mineral substrates affected by rising damp, penetrating damp, condensation, leaks, or flood damage. Apply 1–2 coats depending on surface condition, allow to cure, then use as a standalone matt white finish or overcoat with emulsion or oil-based top coat for a decorative finish.

Manufactured in the UK to rigorous standards and trusted by professional decorators, property maintenance teams, and flood recovery specialists for reliable performance on damp surfaces and rapid turnaround projects.

Coverage may vary depending on surface porosity, texture, and moisture content. Porous, textured, or heavily damp surfaces may require more paint. For accurate project planning, we recommend ordering 10–15% extra to account for surface variation and touch-ups.

Important: For heavily damp surfaces or severe efflorescence, 2 coats recommended for complete coverage and adhesion. Lightly damp surfaces or minor leak recovery may only require 1 coat.

Surface Preparation:

Damp Walls & Ceilings:
• Remove any loose, flaking, or peeling paint with a scraper or wire brush
• Clean surface to remove dirt, dust, grease, and organic growth (mould, algae)
• Treat mould with fluxaf Mould and Mildew Remover wash and allow to dry before application
• Brush off efflorescence (white crystalline salt deposits) with a stiff brush - do not wash off as this reintroduces moisture
• Surface can be damp but should not be dripping wet or have standing water
• The paint will adhere to damp surfaces, but ensure surface is stable and not saturated

Leak Recovery & Flood-Damaged Surfaces:
• Ensure leak source is repaired before application (this paint adheres to damp surfaces but does not fix leaks)
• Allow standing water to drain and remove any saturated materials (wallpaper, loose plaster)
• Clean surface to remove mud, silt, and contamination
• Treat with Fluxaf mould and Mildew Remover if mould is present
• Surface can be damp but should not be saturated or dripping
• Apply as soon as surface is stable (no need to wait weeks for complete drying)

Walls Suffering from Damp:
• Identify and address the source of damp if possible (rising damp, penetrating damp, condensation)
• This paint will adhere to damp surfaces and prevent peeling, but it does not solve the underlying damp issue
• Remove loose material and clean surface as above
• Apply to damp-affected areas to prevent paint failure whilst investigating or resolving damp source

Application:
• Stir paint thoroughly before use and occasionally during application
• Apply in temperatures between 10°C and 25°C for optimal drying
• Ensure good ventilation during application and drying (oil-based product)

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

Coo-Var Anti-Damp Paint is a specialist oil-based paint that adheres to damp surfaces, preventing the peeling and flaking that occurs when decorating walls affected by damp or recovering from leaks. Use it when you need to paint damp walls without waiting weeks for complete drying, or when standard emulsions are peeling due to moisture in the substrate.

Does Coo-Var Anti-Damp Paint block or seal damp?

No, Coo-Var Anti-Damp Paint does NOT block or seal moisture sources. It adheres to damp surfaces and prevents paint peeling, but it does not stop damp, waterproof walls, or solve the underlying damp problem. You should still identify and address the source of damp (leaks, rising damp, condensation) for a permanent solution.

Can I apply Coo-Var Anti-Damp Paint directly to damp walls?

Yes, you can apply it to damp surfaces, but they should not be dripping wet or have standing water. The surface should be damp to the touch but stable. Remove any standing water, allow excess moisture to drain, then apply. The oil-based formula adheres to damp substrates where water-based paints peel and flake.

Will Coo-Var Anti-Damp Paint stop my walls from being damp?

No, this paint does not stop damp or prevent moisture ingress. It adheres to damp surfaces and prevents paint peeling whilst the wall continues to dry naturally or whilst damp is present. To solve damp problems, you must address the source (fix leaks, install damp-proofing, improve ventilation, etc.).

Do I need to overcoat Coo-Var Anti-Damp Paint with a decorative finish?

No, Coo-Var Anti-Damp Paint can be used as a standalone matt white finish. However, if you want a decorative colour, you can overcoat with breathable emulsion, vinyl matt, vinyl silk, or oil-based top coat after 24–48 hours. Two coats of top coat typically required for full coverage.

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

For lightly damp surfaces or leak recovery, 1 coat is usually sufficient. For heavily damp walls or complete coverage, apply 2 coats. Allow minimum 16 hours between coats. Always assess the surface condition before deciding on coat quantity.

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

Touch dry in 8 hours, hard dry in 16 hours at 20°C. Allow minimum 16 hours before recoating. Wait 24–48 hours before overcoating with decorative finish (if desired). Full cure is 7 days. Drying times may be extended in cooler temperatures, high humidity, or on very damp substrates.

Can I use Coo-Var Anti-Damp Paint on exterior walls?

No, Coo-Var Anti-Damp Paint is for interior use only. It's designed for interior walls and ceilings affected by damp, leaks, or flood damage. For exterior damp control, consult our experts for suitable exterior-grade solutions.

Can I spray Coo-Var Anti-Damp Paint?

Yes, you can spray Coo-Var Anti-Damp Paint using airless sprayer or HVLP spray gun. Thin with Coo-Var Thinners 14 (max 10% by volume) for spray application. Ensure good ventilation and wear appropriate PPE. Brush and roller application do not require thinning - apply as supplied.

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

Coo-Var Anti-Damp Paint provides approximately 9 m² per litre per coat on smooth surfaces. A 1L tin covers 9 m², and a 2.5L tin covers 22.5 m². Porous, textured, or heavily damp surfaces may reduce coverage. We recommend ordering 10–15% extra for surface variation and touch-ups.

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

Yes, Coo-Var Anti-Damp Paint contains a biocidal component to prevent mould and mildew growth on treated surfaces. However, it's important to address the source of damp (leaks, condensation, poor ventilation) to prevent recurrence. For existing mould, treat with fungicidal wash before application.

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

Coo-Var Anti-Damp Paint is an oil-based (solvent-based) product with high VOC content and is flammable. Ensure good ventilation during application and drying. Avoid application in occupied spaces with poor airflow. Keep away from heat sources and open flames. Wear appropriate PPE and follow safety guidance on the label and SDS.

How do I clean tools after using Coo-Var Anti-Damp Paint?

Clean brushes, rollers, and spray equipment immediately after use with white spirit or SPO Brushwash and Thinners. Do not allow paint to dry on tools. Dispose of cleaning materials responsibly according to local regulations.
