Primarily used for priming concrete roofs, floors, cementitious screeds, and renders, EVERBUILD BLACK JACK 902 BITUMEN & FLASHING PRIMER is also suitable for bitumen felt, asphalt, mastic, weathered corrugated iron, steel, and wood. Additionally, it serves as an excellent primer for applying BLACK JACK FLASHING TAPE.
Surface Preparation:
Proper surface preparation is essential to ensure strong adhesion and durability of the coating. All surfaces must be sound, stable, clean, and thoroughly dry. Metal surfaces should be wire-brushed to remove rust, and for long-term protection, a rust-inhibitive product like red lead or zinc phosphate is recommended. Remove loose or blistered paint, including tar-based systems. New galvanized surfaces should be roughened with a wire brush or treated with an etch primer.
Application:
EVERBUILD BLACK JACK 902 BITUMEN & FLASHING PRIMER is ready to use and should not be thinned. Apply by brush or spray, ensuring a thin, even coverage by scrubbing it in well with a brush. Avoid pooling when using spray applications. For fiber-cement or rag felt, apply generously to fully saturate the surface.
Cleaning of Tools:
Clean tools with white spirit, and wipe away any spillages before the primer sets.
Limitations:
- Do not use in areas where contact with solvents is expected.
- Avoid inhaling vapors, especially in confined spaces.
- Ensure sufficient drying time before overcoating.
