How to Prepare a Metal Roof for Painting
Painting a metal roof is not as easy it one may think. Paint will simply not properly stick to a metal roof if the roof has not been prepared for the paint job. Properly preparing a metal roof for painting will eliminate the need of having to paint it a second time because the paint didn't stick.
Supplies needed
Ladder
Water hose
Cleaning brush
Paintbrush
Self-etching primer
Bucket
Roller
Extension pole for the roller
Get the cleaning brush and climb the ladder to get on the roof. Clean the roof with the cleaning brush. This will help loosen up dirt and any rust particles that may be on the roof.
Climb down the ladder and turn on your water hose. Climb back up the ladder and clean the roof with the water hose. Let the roof dry for at least a 12 hours before you move on to the next step.
Get your bucket and pour the self-etching primer into it.
Climb the ladder and bring the bucket of self-etching primer to the top of the roof. Use your roller to apply the primer to the surface of the roof. For spots that are far away, use the extension pole for the roller. Coat the roof thoroughly with the primer and be sure not to miss any spots.
Use the paintbrush to get the primer on any spots that may be hard for the roller to coat. The paintbrush is great to use on crevices that the roller does not coat.
Let the primer dry for a day before you start painting.
