If your home has steel gutters, you know that over time their exposure to outside climates can cause rust spots and peeling paint. This can make your home look run down and neglected and lower your property value. You could replace your gutters, but why do that when you can save time and money by painting your steel gutters yourself. With the proper primer and paint, you can make your gutters look brand new and protect them from future exposure. A fresh coat of paint is all you need to improve the exterior appearance of your home.

Step 1: Clean the Gutters

Before you can do anything with your steel gutters, you must thoroughly clean them. To clean them, it is best to start at one end of your gutters and work your way down. Place your ladder securely at the end you’re starting with. With your gloves on and a plastic trash bag in hand, scoop all the leaves and debris out of the gutter and place them in the trash bag. Do this the whole length of your gutter. Make sure you inspect the downspout. Scoop any leaves and debris out of it also.

Next, add dishwashing liquid to your bucket and fill with water. Move the ladder back to the end of the gutter you started with. Use a grout sponge or scrub brush and clean your gutters with the soapy water. This does take some work. Your gutters must be free of grime and dirt to ensure the best paint job. After your done washing, you need to rinse the soap off with your water hose. Make sure you spray at a downward angle and rinse thoroughly. You are now ready to inspect and repair your steel gutter.

Step 2: Repair Any Leakage

Before you paint your steel gutters, you want to repair any holes or cracks in them. Fixing Cracks are the easiest. Fill them with silicone caulk and let dry. Fixing Holes is more complicated. Measure your hole. If you have a gutter patch you can use it. If not, cut a patch from the metal flashing that is just a bit bigger than your hole with your metal snips. Use your putty knife and apply the asphalt flashing cement to the back of the piece you just cut or your patch. Place over the hole. If there is adhesive oozing out, smooth with your gloved finger. Let dry. If you have leaking joints, remove the joint, clean, caulk, and put everything back together. Make sure you test all your repairs with water before you proceed.
