SURFACE PREPARATION AND APPLICATION
Mild steel, previously painted
1. Check adhesion of existing paint using a cross-hatch adhesion test. Using a Stanley knife to cut through the paint surface. Do this vertically and horizontally to the substrate, approximately 3mm apart, creating little squares. If the edges of the squares curl up, and the square can easily be removed, this means the adhesion of the old paint system is failing. If the paint system is failing, remove all coating and bring the metal surface area back to bright steel.
2. Prime bright steel with 2 coats of EnviroPrime or 1 coat of AllPrime Plus (see Data Sheets).
3. Apply 1 coat of Paintcor’s UniSub Universal Undercoat. Allow drying.
4. Finally apply 1 or 2 coats of Paintcor’s HiGlo, LoGlo, or EnduraCoat Enamel.
5. If the existing paint system is adhering well, degrease the surface area if necessary. Rinse well and allow sufficient time to dry.
6. Lightly sand the existing paint system to a clean matt finish. Wipe the surface with a moist cloth to remove any sanding dust. Allow drying.
7. Apply 1 coat of Paintcor’s UniSub Universal Undercoat. Allow drying.
