Surface Preparation

Ensure the surface to be primed is clean, dry, sound and free from wax, grease and oil. If you are preparing wood or plaster, remove loose/ flaking paint, clean to a bare surface and sand smooth. Remove any fungal growth or mould with Blackfriar Concentrated
Fungicidal Wash prior to application. Treat any knots or resinous wood with Blackfriar Patent Knotting and allow to dry before applying Blackfriar Multi-Surface Primer. If preparing iron and steel, remove any rust and mill scale with a wire brush, clean back to a bright surface, and prime immediately. 

Technical Data

• Interior and exterior use.
• For multiple surfaces prior to painting.

Up to 12m2 per litre per coat. Coverage may vary depending on method, rate of application and roughness of surface. 

Directions for Use

Stir thoroughly before use. Apply one coat of product by brush or roller except on ferrous metals and porous surfaces where two coats are required. For porous surfaces, dilute the first coat with 10% water. If applying two coats lightly sand the first coat prior to applying the second to remove any imperfections. Please note when applying to copper, the primer coat may turn blue - this colour will not be visible once a top coat is applied.
