How to Paint Aluminum Gutters

how-to-paint-aluminum-guttersKnowing how to paint aluminum gutters gives you a tool that can help you make your gutters look nicer. Painting them can also help improve their lifespan (though seamless aluminum gutters come with a 30 year lifespan as it is).

Painting your gutters is a simple job, if not exactly an easy one. Here’s what you’ll need.

  • Sandpaper
  • Paint scraper
  • Sponges and scrub brushes
  • Soap and water
  • Paint brushes
  • A ladder
  • An oil-based metal primer or acrylic bonding primer
  • An oil-based satin or gloss enamel
  • Oil-based paint

Before you go to the paint store you need to note a couple of paint tips. First, you need to look for ammonia-free primers. Ammonia reacts with aluminum to create a layer of gas between the aluminum and the paint, which can create a bubbling effect. Eventually, this bubbling will ruin your paint job.

Second, you need to make sure your enamel is satin or gloss because these will help your gutters repel water simply because they are non-porous.

You might want to make sure that you’re going to have a few days of dry weather before you tackle this project. Check the forecasts!

Start by performing a standard gutter cleaning, getting rid of all debris. You’re also going to need to remove any previous paint. That means that you’re going to have to take the sandpaper or the scrubber to your gutters until every scrap of the old paint has been removed.

Once you’ve done that you’re actually going to have to scrub down your gutters with soap and water. Sadly, you can’t simply pressure-wash them for this project.

Once your gutters are squeaky clean you can start with the primer.

Then, you’ll need to let the primer dry. This will take about 48 hours.

The enamel comes next. You’re going to need two coats, and, again, you’re going to need to let each one dry. 48 hours is a safe number once more — you can see why you were looking for several days of good weather.

You can then apply the paint in its final color. This will make your whole exterior look fresher! It’s not a bad project to take on if you’re planning to sell your house, since it will help make everything look a lot fresher.

    Thanks for reading our blog and leaving a comment! You’ll want to use a clear acrylic bonding primer or an oil base metal primer. If you go with the latter, you’ll need to thin it with thinner. The best thing to do is go to a professional paint store like Sherwin Williams and ask them what primer they would recommend. Our aluminum gutters come pre-painted with a 50-year paint warranty so we haven’t had to deal with painting gutters. Usually when we get calls from customers that have old, faded aluminum gutters they just want them replaced so we don’t have a lot of experience actually painting gutters ourselves – but we know it can be done as some people go this route.
