Five steps to coloring your aluminum gutters

Decide if you need to remove the gutters for painting.

Before you do anything, you must decide on the feasible removal of your gutter system.

To begin with, if you are painting the entire system, suppression may not be customary.

You’ll probably do a better job of painting every nook and cranny looking great, but remember that your gutters hang well above the floor level of your house.

Will anyone notice a small patch on the undercarriage that didn’t receive a finished brush from that second cover?

Of course, when we talk about downspouts, it makes more sense since they run along the side of your house and have a huge aesthetic impact.

The same happens if you are painting one or two parts of the gutter system to correct the visual clash of previous damages in one sector so that the respective parts match with the rest.

Then there are those of you with a moderate to high fear of heights who shudder at the thought of spending all that time there painting an entire sewer system.

Here again, it makes sense to remove part by part and paint them in the safety of your grounds.

Instead, fill a bucket with not too hot water, add a healthy dose of liquid dish soap, add a large sponge, and bring in a bristle scrubbing brush.

Proceed to scrub the gutters with a circular motion, cleaning away loose paint dirt and debris accumulating in the foam.

Once cleaned, inspect the gutters for protruding notches and scratches that will cause the brush to snag and leave a scratched facade.

Sand these spots with aluminum oxide or silicon carbide sandpaper. When your gutters are clean and smooth, you can elaborate them for painting.

Some great acrylic primers work very well: Perry & Derrick “Chalk-Tite Clear” (800-227-2468) and William Zinsser “Bulls Eye 123” (732-469-4367).

The oil-based primer should be diluted with a solvent. Read the instructions on the can of base paint and finished acrylic paint. They will tell you how long to let the primer dry.

It is not an acceptable initiative to wait much longer than suggested, or the finish coat will not adhere properly to the primer and will peel prematurely.

Your paint must be equal to your primer and enamel, so be sure to check with your hardware store manager when you pick up your cans.
