In this video, painter Jim Clark shows how to ready old, faded aluminum siding for a fresh coat of paint.
1. Don rubber gloves and mix one cup bleach and one cup TSP with one gallon of water in a 2-gallon bucket.
2. Dip an abrasive pad into the cleaning solution and scrub the siding of all dirt, mold, mildew, and chalky pigment residue.
3. Wipe the siding dry with clean cloth.
4. To clean larger areas, use a pressure washer fitted with fan-spray tip. Work from top of wall down, making sure not to shoot water under siding. Always wear safety goggles when using the pressure washer.
5. To remove paint from siding, use a random-orbit sander and 100-grit abrasive disk, Attach the sander to a wet/dry vacuum that's equipped with a HEPA filter.
6. Once the siding is clean and dry, apply one coat of 100 percent acrylic-latex primer, followed by two coats of 100 percent acrylic-latex paint.
