1. Surface Requirements
- The surface must be:
- Clean – Free of dust, oil, grease, wax, and old flaking paint.
- Dry – No moisture present.
- Smooth and uniform – To ensure the hammer effect develops properly.
2. Surface Preparation by Substrate
- Bare Metal (Iron/Steel):
- Remove rust, scale, and old paint by wire brushing, sanding, or grit blasting.
- Wipe with a solvent or thinner to remove grease/oil.
- Apply a suitable Multilac metal primer (e.g., Red Oxide Primer or Zinc Phosphate Primer) for enhanced protection.
- Allow the primer to dry fully.
- Galvanized or Aluminum Surfaces:
- Lightly sand or abrade the surface to dull the sheen.
- Clean with a degreaser or thinner.
- Apply Multilac G.I. Adhesion Promoter as a bonding primer.
- Let it dry completely.
- Previously Painted Surfaces:
- Remove loose or flaking paint with sanding or scraping.
- Smooth out glossy areas with sandpaper.
- Clean and degrease thoroughly.
- Spot prime bare metal if exposed. Final Cleaning: Wipe surface with a dry lint-free or tack cloth to remove all dust particles.
- Ensure the surface is completely dry before painting.
3. Ready for Application
- Once the surface is:
- Rust-free.
- Primed (if needed).
- Clean and dry.
- It is ready for applying Multilac Hammer Finish Paint using a brush, roller, or spray (spray recommended for best hammer effect).
