What To Know About Painting Aluminum Siding

Aluminum siding is an older type of siding, but a lot of people do still have this type of siding on their homes today. If you still have this siding on your home, it may have begun to chalk and may be stripped of its color. If you have this issue but your siding is still in good condition, you may want to consider painting it to give it new life. Read on for everything you should know about painting aluminum siding.

What You Need For The Job:

  • Exterior paint
  • Paintbrushes
  • 3/8" nap rollers
  • Extension poles
  • Siding cleaner
  • Garden hose


  1. To start, you should clean your siding to help remove any chalking that has started, as well as stains on your siding and dirt that has accumulated. Use a scrub brush or sponge to remove stains that are tougher to get off with just a garden hose. You don't want to use a pressure washer on the siding, as it can damage the siding and leave it with dents or dings.
  2. Once the siding is clean and dry, you should inspect it for any damage. You can repair damage in aluminum siding using paintable exterior caulk and a sanding block to smooth it out. Repair holes or cracks in the siding before you paint it.
  3. After your siding has all been repaired, you can begin painting it. Be sure that you have plenty of sunshine in the forecast and warm enough weather so you don't have issues with your paint being ruined by rain or by weather that is too cool (or too hot). Your paint can dry too quickly on days that are too hot, and it can gum up on days that are too cold.
  4. Begin painting by cutting in around the edges using a paintbrush. Paint around the gutters, soffit and fascia, and other trim work you aren't planning on painting, then use the paintbrush to paint beneath the clapboard pieces.
  5. Blend all of your paint together using the roller to roll the paint on the face of the siding. Roll the paint on evenly and smoothly. Continue painting until you have painted all sides of your home. Allow the paint to dry, then apply a second coat if needed. If your aluminum siding was chalky and worn down to the point that you could see the silver color below, you may need several coats of paint.

If you have aluminum siding and it is in good shape, give it new life by painting it. Painting the entire exterior of a home is a major job to take on. If you don't think you can handle a job of this magnitude, you should hire a company that offers exterior home painting services to do the work for you.
