Coo-Var Alkali Resisting Primer Sealer
This primer is best suited for use on internal and external walls, plaster, brick, and screed. It stabilises these surfaces, providing a strong, even base for subsequent coatings. The primer seals the surface, preventing the topcoat from deteriorating due to alkali damage, commonly seen in new plaster or concrete surfaces.
- Walls and plaster
- Brick and screed
Application Instructions
Before application, ensure the surface is clean, dry, and free from grease, oil, or other contaminants. For unstable surfaces, use a masonry stabiliser to prepare the area. The primer can be applied with a brush or roller. Apply in temperatures above the dew point to avoid condensation issues.
Limitations
Do not use the primer on surfaces with excessive moisture or where there is a constant water presence. The product should not be applied in poorly ventilated spaces or where temperatures are below 5°C. Do not apply over damp substrates or on surfaces exposed to high humidity without proper ventilation.
Additional Recommendations
For the best results, use a suitable topcoat after applying the primer. If you require a topcoat that complements this primer, consider our range of compatible masonry paints. Always consult the product data sheet before use to ensure compatibility and correct application techniques.
Health and Safety
