How to Paint Galvanized Gutters

As mentioned already, a galvanized gutter system is a smart investment. Offering the right balance of cost-effectiveness and durability, it’s a fantastic addition to your home. But gutters can take a beating, particularly in areas with severe weather or four seasons. After a while, your gutters might be in need of a recoating. Let’s check out how to do so step by step.

Step 1: Clean

If you’re dealing with brand-new gutters, then a washing (with water-based cleaner and then white vinegar) will suffice. If recoating, then you’ll need to either wash thoroughly or (if the current paint is in fairly worn condition) use a scraper, wire brush, and some other items.

  • Be sure to use gloves (and eye protection) while using chemical cleaners.
  • To start, you’ll need a ladder (preferably an extension one), bucket, sponge, lint-free cloth, scouring pad, and a water-based cleaning agent or mild dish detergent. Apply reasonably firm pressure to ensure proper removal of heavy sediment, oil, and other materials. Once you’ve fully cleaned your gutters, allow to dry.
  • Next, take white vinegar and apply it to the gutters. This will etch the surface and ensure that new paint will adhere properly. Again, allow to dry prior to the next step.
  • When dealing with peeling paint and the like, you’ll need to break out some more tools. These can include a wire brush and paint scraper. Also, you can consider using an infrared paint remover. Gently remove loose paint with tools (as well as any rust or residues).  
  • Finally, if you’ve had to follow the brushing and scraping step, thoroughly clean the gutters and allow them to dry. This will ensure proper paint adhesion down the line.

Step 2: Sand

Have older gutters or live in an area with severe weather conditions? You might notice the paint starting to form a chalky substance. If this is the case, you’ll want to sand your gutters.

Take sanding paper – coarse grit for rough spots and finer grit for smoother areas – and use a light amount of pressure across the length of the gutters. You can increase pressure for more stubborn spots, but just be careful to not apply too heavy-handed sanding. This is important because the gutters might be in a weakened state, which can lead to breakage.

Once you’re done sanding, you should have a nice smooth surface without any chalky residue. Make sure to clean off any dust before you start mixing primer. 

Now, on to the actual painting!

Step 3: Prime

Painting prep done? It’s time to lay down some coats! Remember, not any primer will do. You’ll need to source one that’s latex-based and specifically designed for metal.

Using a large paintbrush, coat all exposed areas of the gutters. Your painting technique doesn’t have to be perfect. Just make sure there’s ample coverage and it’s decently smooth. Apply the first coat evenly, let dry, and then apply a second coat.

Primer serves two purposes. It allows the finishing coats to adhere to the surface, as well as provide a protective layer against rust and other forms of damage.

Step 4: Paint (High-Quality Latex)

Ready to freshen up the look of your gutters? Once you’ve primed them and allowed them to fully dry, you can apply the paint. Again, you’ll want to get your hands on a high-quality latex product. It’s also recommended to use the same brand of paint as the primer.

As with the priming, use large and clean paintbrushes. Make sure to cover all exposed surfaces of your gutters with an even coat. Apply paint with back-and-forth brush strokes along the length of the gutters. Then, let it fully dry. If a second coat is required, repeat the process.

Note: Always ensure that your ladder is firmly on the ground while painting. It can be easy to place your ladder in a precarious position, especially if you’re tired or it’s getting dark. Always practice safety when painting from any given height.

If you are not comfortable with painting your own gutter system (or simply don’t have the time, energy, or ability to do it yourself), you can always count on SPOUT to connect you with fast, efficient & affordable gutter specialists!

Step 5: Clear Coat

Okay, so you’ve gotten through the first four steps. Congrats! But we’re not finished yet.

To provide even greater protection, you’ll want to apply a clear coat. Wait at least a day for the latex paint to dry prior to application. Once ready, take a paintbrush and apply a single layer of clear coat. This will safeguard your hard work from rust and inclement weather.

And there you go! With these easy-to-follow steps, you can protect your investment and improve the aesthetics of your home.
