Method of use
Preparation:
Apply by brush. Preparation of the surface is of great importance for any surface coatings and will influence the degree of adhesion obtained and the life of the coating. All surfaces must be stable and thoroughly clean.
Metal surfaces should be wire brushed to remove rust. Where long term protection is required, an initial treatment of a rust inhibitive product such as zinc phosphate should be used. A minimum of two coats should be applied, the first being allowed to dry before the second is applied.
NOTE: Anticorrosive bitumen black paint may bleed through any paints subsequently applied over it. Apply a primer recommended by the paint manufacturer before painting over it.
