Paint a Metal Roof or Awning
Doug owns a bank building with a metal awning over the entry way. How do you paint the metal awning?
- Pressure wash to remove dirt, grime, chalk, and other contaminants.
- Sand to remove and loose paint and feather edges.
- Clean with mildew retardant solution if necessary. Let dry thoroughly.
- Scuff sand if coating is high gloss and wipe off sanding residue.
- The pitch of the roof or awning must be greater than 2/12. If it is not, you will need a roof membrane system (not available at Rodda).
- If, on the current roof or awning, water beads up like on waxed paper, do not paint. Paint adhesion will likely fail.
Caution! Things to consider
- Roof or awning must have slope, as paints will blister with standing water.
- Maintaining a wet edge while painting is critical.
- Wind can affect overspray drift distances.
- If roof or awning is non-ferrous metal, use XIM UMA as the primer.
- Please read manufacturers instructions prior to coating.
- Check substrate temperature prior to coating. Try to avoid painting in direct sunlight. Overcast days work best.
