Product Information
Full details
The Coovar All Purpose Primer in White is designed for DIY enthusiasts and professionals seeking a single, reliable primer for a wide array of surfaces. Its key benefit is its versatility, acting as a preparatory coating that enhances adhesion, seals surfaces, and provides a uniform base for your chosen topcoat. A minor caveat is its water-based formulation, which may require specific application techniques for optimal results on certain non-porous materials. This 1-litre can offers a matt, white finish that is touch dry in 1.5 hours and hard dry in 4 hours, with recoating possible after 6 hours.

Troubleshooting
Primer not adhering well
Ensure the surface was properly cleaned and prepared (free of dust, grease, and loose paint). Roughen glossy surfaces to create a key. Stir the primer thoroughly before application.
Uneven finish after topcoat
The surface may have been too porous or not adequately sealed by the primer. Apply a second thin coat of primer if necessary, ensuring adequate drying time between coats. Ensure even application of the primer.
Primer remains tacky after several hours
This could be due to thick application or poor ventilation. Apply thinner coats and ensure good airflow. Check environmental conditions; high humidity can slow drying. Avoid recoating until fully dry.
Difficult brush marks visible
Apply primer evenly using a good quality brush and avoid over-brushing. Work in manageable sections and maintain a wet edge. Thinning the primer slightly with water may help in some cases, but follow manufacturer recommendations.

Setup, Compatibility & Care
Setup: Ensure the surface to be primed is clean, dry, and free from dust, grease, and loose material. Sand any glossy surfaces to provide a key. Stir the primer thoroughly before use. Apply using a brush in a well-ventilated area.
Compatibility: This water-based primer is generally compatible with most water-based and solvent-based decorative paints. However, it is always recommended to test on a small, inconspicuous area first, especially when using high-performance or specialist topcoats. It is suitable for wood, plaster, masonry, and metal (including aluminium).
Care: Store in a cool, dry place, away from direct sunlight and frost. Keep the container tightly closed when not in use. Clean brushes and equipment immediately after use with water.
