Aluminum siding used to be all the rage some 25 years ago, but now the more modern vinyl siding has followed in its footsteps. The foregoing not withstanding, aluminum siding is a singularly durable exterior product, and those whose homes are ensconced are loath to give it up. Learning how to repair a hole in aluminum siding allows you to keep your exterior looking great for years to come.
How to Repair a Small Hole in Aluminum Siding
Clean the area around the hole with soapy water. Rinse it thoroughly to remove any soap and debris, and then dry the area with an absorbent paper towel.
Sand the area around the hole lightly to increase adhesiveness. Remove any dust from the sanding with a moist paper towel.
Follow the instructions on the two-part epoxy product and carefully mix a small batch. Since the specifications vary by brand, it is crucial to read the package insert in its entirety ahead of time to avoid any surprises and last-minute trips to the hardware store.
Apply the two-part epoxy filler quickly. Unless you purchase the kind that can only be applied with an applicator gun, it is best to put on the mixture by hand with a small putty knife.
Let the substance dry for about 30 minutes. Gently sand it down to match it to the surrounding aluminum area.
Primer and paint the repaired section of aluminum siding so that it matches the rest of the siding. Protect the area from moisture and dirt for at least 12 hours.
How to Repair a Large Hole in Aluminum Siding
Take the X-acto knife and cut out the portion of the aluminum siding that contains the large hole. The less you have to cut, the better.
Sand the corners of the area you cut and lightly sand an area of about 1 inch on both sides, the top and bottom of the gap.
Cut a portion of the intact siding material to match the piece you just cut out. Add an additional inch on either side and to the top and bottom measurements of the piece.
Apply the adhesive caulk around the area of the cut, and place the cut to fit piece of new aluminum siding over it. Press down gently until a bit of overage squeezes out all the way around.
Allow the caulk to dry overnight. Cut away the overage very carefully with the X-acto knife.
