How To Paint Gutters

| 16 August 2017

Many people choose to paint their gutters so that they fit better with the overall theme of their home. Some people purchase a home with existing gutters that they feel need some TLC. Regardless of the reason you are painting your gutters, below are some tips to help you make sure that you do it correctly, and don’t do any damage to the gutter installation. The way that you paint your gutters will differ depending on the material. The two most common gutter materials are aluminum and steel. Below are tips for painting each.

Tips For Painting Gutters


Before you start you are going to need the following: a paint scraper, primer, grout sponges, safety gear, paintbrushes, a ladder, a hose, and dish soap.

The first thing you need to do is remove the old paint. Use the paint scraper to remove as much of the existing paint as possible. Next, in order to ensure that the new coat of paint really sticks, you need to clean the gutters with the grout sponges and soap and water. Once you’ve cleaned the gutters, apply the hose and thoroughly rinse them. Make sure no water pools in the gutters while you are doing this.

It is now time to prime the gutters and then apply the paint. It is a good idea to wear gloves and goggles during this step so that you avoid getting any toxic primer on your skin. It is also a good idea to make sure you buy primer that doesn’t contain ammonia, as it is liable to interact with the aluminum and create gas bubbles under the paint.


To paint steel gutters you are going to need the following: a ladder, a bucket, grout sponges or scrub brushes, metal snips, asphalt flashing cement or gutter patch, oil-based rust inhibitor primer, gloves, a hose and spray nozzle, dish soap, silicone caulk, a putty knife, a foam sanding block, a paint scraper, and paint.

The steps for prepping your steel gutters for repainting are quite similar to those of aluminum gutters. First, you need to remove the downspout braces, as you’ll paint those separately. Next, clean your gutters out thoroughly. Using the grout sponge or scrub brush, apply the soapy water and give the gutters a good scrubbing.

Because steel is prone to rusting in a way that aluminum is not, you might find that the oxidation has actually cracked and eaten holes in certain parts of the gutter. You need to fill the cracks with caulk and let it dry. The holes need to be sealed up with the asphalt flashing cement, using the putty knife to smooth the material out before letting it set and dry.

Sand the gutters and downspouts so that the are free of oxidization after you’ve repaired any rust damage. Then, apply a good oil-based primer with rust protection. You need to apply a good 3 or 4 coats (allowing each one to completely dry in between). Now it is time to paint. Use an oil-based enamel, or exterior latex paint. It’s best to use a stain, gloss, or semi-gloss paint to repel water, dirt and grime.

Painting your gutters is not as simple as it sounds, so you should consider bringing in gutter installation experts to make sure you get it done right the first time. If you are thinking about repainting your gutters, and you know a bit about gutter installation, keep the above information in mind to make sure your gutters look great, and continue to protect your home.
