Painting a Metal Roof. Painting with an airless paint sprayer.

What happens here

Using an airless spray gun, apply a DTM (Direct-to-Metal) bonding primer to the entire clean and masked metal roof surface. The primer, which appears white/light gray, should be applied evenly. Work systematically across the roof, ensuring complete coverage to promote adhesion of the final paint coat and provide a uniform base. The painter moves across the roof, carefully spraying each panel.

Goal: Prime the metal roof for paint adhesion
