How To Paint Aluminum Siding?

Many homeowners in Toronto tend to remove the old aluminum sidings. Instead of replacing the old aluminum siding, it is more cost-efficient to repaint it. It is a simple process that can be completed in less time than you think. Often the question arises on how to paint the old Aluminium siding? In this article, we discuss the process in simple steps.

Steps to be Followed in Painting Aluminium Siding

Step 1: Repair the Damages

Repair all the damages that are present on the siding. Any sagging and separation, especially where the roof meets the wall, should also be inspected.

Step 2: Clean the Surface

Use sandpaper to scrub the surface of the siding. After using the sandpaper use a pressure or power washer to clean up the surface.

Step 3: Fill the Gaps or Holes with Caulk

Siding with holes will not be beautiful after painting. So be sure to fill all the gaps on the siding surface. Caulking is the best process to fill up the holes. Use a caulking solution to fill up the holes and cracks in the siding.

Step 4: Apply the Primer

Before going to the actual painting, first, apply the primer. The primer must be well paired with the paint that you are going to use on the siding. Always use two coats for that extra protection of the siding. Avoid using latex primer as it reacts with aluminum siding and fails to stick to the paint applied afterward.

Step 5: Apply the Paint

Depending on the paint you chose, the number of coatings can be changed. But always be sure that you have a minimum of two coats applied. Depending on the surface and your convenience you can use rollers or brushes. Spraying is also another technique used, but be sure that the climate is not too windy when using the sprayers for painting.

Step 6: Keep an Eye on the Climate

Do not go for painting if it’s too hot or raining. Always give a gap of one day after applying the primer to the siding. Give time for the primer to stick well to the surface.


Painting an Aluminum siding is more complicated than the painting surfaces of the wall and other surfaces, there are many real-world scenarios in Canada where homeowners attempted the job and tend to fail which leads to the loss of hard-earned money and valuable time. So, it is a wise decision to hire a professional to paint your exterior aluminum sidings rather than doing it yourself or removing the sidings to save you thousands of dollars.
