Aluminum siding can last for many years with minimal maintenance, but it will eventually need to be repainted. Not only does paint peel and crack over time, but your aluminum siding painting project is also a great opportunity for you to do a damage assessment.

With the right preparation and techniques, you can paint your aluminum siding like a pro and achieve a long-lasting finish. In this blog post, we’ll show you how to do just that.

So whether you’re planning to repaint your aluminum siding or are just considering it as an option, read on for some tips that will make the process go smoothly.

What To Do Before Painting Your Aluminum Siding

Newly painted aluminum siding

  • Check the weather to make sure it’s mild enough for painting and that it won’t rain. Keep in mind that an exterior painting job, especially if it is DIY, may take more than one day or even a weekend to finish
  • Get high-quality tools and materials so your paint job will look its best and last for a longer time
  • Do a damage assessment of your aluminum siding. You may have to replace certain areas if the damage is bad enough that repairing it is out of the question
  • Look out for wasp and bird nests; they are not fun to run into unexpectedly

How To Paint Aluminum Siding In 6 Steps

1. Prepare The Area

Prepping a house for painting

Following proper preparation procedures before you paint aluminum siding helps make cleaning up much easier. Here’s what you can do:

  • Trim any plants back so you and a ladder can fit. This prevents you from crushing your plants or them scratching you
  • Put down drop cloths. This protects your plants from errant paint, which can be toxic for them

2. Make Any Repairs

By taking the time to repair any damage to your house exterior before painting, you can be sure that your paint job will last for years to come. Not only will this save you time and money in the long run, but it will also help to keep your house looking its best.

One of the most common problems with aluminum siding houses is scratches and dents. This damage can not only be unsightly, but it can also lead to moisture damage and mold growth. Luckily, repairing aluminum siding is relatively easy; you can simply sand down the damaged area and then repaint it.

Another common issue is cracking or chipping paint. This can happen for a variety of reasons, but it’s generally caused by temperature changes or moisture damage. The best way to fix this problem is to scrape off any peeling paint and then sand it flat.

*You may also need to apply a primer before painting, depending on the severity of the damage

3. Clean The Siding

Power washing siding

If you’re painting aluminum siding, it’s important to give the surface a good cleaning beforehand. This will help the paint to better adhere to the siding and will also provide a more even paint job.

To clean the siding, start by using a power washer to remove any dirt, dust, or cobwebs. Once the surface is dry, use a mild detergent to scrub away any remaining grime. You also have the option of adding TSP (trisodium phosphate) to your pressure washer to get a two-for-one deal. Rinse the area well and let it dry completely.

*Keep in mind that it can take several days for the exterior of a house to completely dry. Painting on a damp surface will only cause your paint to fail faster, meaning you will have to repaint it again sooner.*

You may have to replace the boards if the damage is bad enough. Painting over damages will only result in the paint peeling or chipping more quickly, harming your curb appeal.

4. Mask Windows And Doors

Masking on windows and doors

When it comes to painting the exterior of your home, one of the most important things you can do is mask off any windows and doors. This will protect them from paint splatters and drips and will ensure that you get a clean, professional-looking finish.

Painter’s tape is readily available at any hardware store, and it’s relatively inexpensive. Just be sure to use a high-quality tape that is designed for use with paint, as this will help to prevent peeling and flaking.

5. Apply Primer

Primer helps to create a smooth surface for the paint to adhere to and also helps to protect the underlying material from weathering and wear. When painting aluminum siding, for example, primer can help to prevent the paint from chipping or flaking over time. In addition, primer can also help to hide any imperfections in the surface of the siding.

When applying primer to a wall, it’s important to start at the top and work your way down. This will help to prevent streaks from forming. Once the primer is applied, you’ll need to allow it to dry completely before proceeding with paint. For best results, paint primer should be applied in thin, even layers. When applying primer to aluminum siding, it is important to use a primer that is specifically designed for this purpose.

6. Paint Your Aluminum Siding

Right after painting aluminum siding is done

You can use rollers, brushes, or a paint sprayer. While there is a debate on spray vs brush painting, we recommend using a combination of the three.

Using A Paint Sprayer

If your paint sprayer is equipped with different tips, use a wider tip for large areas and a thinner tip for smaller areas or detailed work. If you’re using an airless paint sprayer, thin the paint according to the manufacturer’s directions. Typically, you’ll add about 10 percent water to oil-based paint and 5 percent water to latex paint.

Simply pour your paint into the paint sprayer, hold down the trigger, and start moving the paint sprayer back and forth across the surface. Be sure to overlap each stroke so that you don’t miss any spots. It’s a great idea to go back over the area with a roller or brush before it dries to smooth out the paint.

Once you’ve finished painting, always clean the paint sprayer thoroughly according to the manufacturer’s directions to avoid paint buildup and clogs.

Using Rollers And Brushes

If you are using a roller, you will need to paint in sections and use a ladder to reach the top of the house. Start by painting the trim around the windows and doors first. Then, paint the body of the house in large sections, starting at the top and working your way down.

If you are using a brush, start at the top of the house and work your way down. Be sure to paint in the direction of the grain of the aluminum siding.
