DIY painting aluminum siding can be done in both ways using a paint roller or spray paints.

How To Paint Aluminum Siding With A Roller

Paint With A Roller

Painting on Aluminum Siding with a roller is quite easier than any other material. Because aluminum is not porous in nature, it doesn’t even soak paints on them, saving a significant amount of paint. In fact, primer is not essential in repainting aluminum siding.

Here is what you will need to paint aluminum siding with a roller

  • Exterior Paint ( Exterior acrylic latex paints are best for aluminum)
  • Paint roller
  • Paint tray
  • Drop Cloth
  • Abrasive Sponge
  • Cleaning Solution
  • Dry Brush
  • Roller Extension Pole
  • Ladder

Here is how you should paint aluminum siding with a roller.

Step 1: Clean the aluminum surface before using a roller on it. If any mildew is formed on the aluminum surface, use a cleaning solution made of 1:4 bleach and water. Spray all over the mildew area and rub with an abrasive sponge. Repeat the process several times and let the place dry completely. However, because aluminum is more subjected to dents and scratches, applying pressure washers can be too much for the surface and result in reverse damage.

Step 2: Use the paint tray and pour some inches of paint on it. Place your paint roller in the tray and gently move it backward and forward over the ribbed part. This will make sure paint is equally distributed to the roller, and excess paint or loose paint is left behind.

Step 3: Use the roller extension pole to hold the roller and start applying the paint with mild pressure. Too much pressure will create paint stroke marks on the aluminum surface. Apply a thin layer of paint on the aluminum surface.

Step 4: While painting, follow the proper direction of the aluminum sidings. Apply paint up and down if the sliding is up and down for each block. For series siding, apply a brush from side to side. This will allow you to have an evenly applied paint all over the entire aluminum surface and have a perfect finish.

Step 5: Once you are done, apply another thin layer of paint on the aluminum surface after a certain time. Avoid using a single thick layer of paint for smooth results. Let the first layer dry completely before you put another layer of paint on it.

If you are using an acrylic primer, let both the primer and paint dry completely before applying another layer of paint.

Step 6: When you are done with each layer, use a dry brush to remove any bumps on the paint.

Note: Keep in mind that you may have to use a brush on edges or corners where it is impossible to paint with a roller.

Also, while having an interior painting project, use a drop cloth to cover all the essentials before beginning the process.
