• Surface Prep: Remove any loose/flaking paint and mould; lightly clean walls.
• Application: Stir thoroughly. Use a brush, short pile roller, or spray—avoid pooling or streaks.
• Drying/Curing: Wait ~16 hours before applying a breathable topcoat. Ensure good ventilation.
• Maintenance: Store leftover paint sealed. If damp persists, investigate the source of moisture. Paint can help but root causes must be addressed.

1. What is Coo-Var Anti-Damp Paint used for?

Coo-Var Anti-Damp Paint is formulated to be applied directly to walls that are still damp from leaks, floods, or rising/penetrating damp. It helps prevent paint failure by controlling moisture release and blocking efflorescence on walls and ceilings.

2. Can I apply this paint on walls that are wet to the touch?

Yes. One of its main benefits is that it can be applied even when the wall is still wet, saving you the hassle of waiting weeks for surfaces to dry. Its special active reagent reacts with surface moisture, ensuring a flake-free finish.

3. Does it help reduce mould or discolouration?

Absolutely. This product contains biocidal protection that minimises mould growth and discoloration, preserving a fresh, healthy look on damp surfaces.

4. How long should I wait before overcoating?

Typically, you should wait about 16 hours before applying a conventional topcoat. Once dry, you can paint over it with a standard breathable emulsion or other compatible finish.

5. Is it suitable for exterior as well as interior use?

Coo-Var Anti-Damp Paint is primarily intended for interior damp areas such as basements, bathrooms, or flood-prone walls. For exterior walls, consult our experts about alternative or additional protective measures.

6. How much coverage can I expect?

Coverage is approximately 9 m² per litre, though it varies depending on how porous or damaged the substrate is. Applying an even coat helps maximise coverage and performance.

7. Does it emit strong odours?

No. Although it’s oil-based, it’s formulated to be low odour, making it more comfortable to use in enclosed or frequently used areas. Always ensure adequate ventilation during and after application for best results.
