painting corroded aluminum window frames
Posted: Thu Dec 20, 2018 3:28 pm
The forward window frames of our 2006 power cat had corroded in spots. They were getting to look pretty bad. I went on the internet and researched ways that people have successfully cleaned and painted aluminum window frames and came up with the process listed below. I was able to do the frames in a day. They now look like new. The new white painted areas blend into the unpainted areas perfectly. Here's what I did.
Scrape off the loose flaking paint.
Sand the area with my Fein Multimaster oscillating sander, 150 grit.
Sand with dry 220 grit then 280 grit paper.
Sand with 400 grit wet. Carefully feather edges from bare aluminum to painted areas.
Wash bare aluminum several times using 50/50 mix of white vinigar and warm water.
Let area dry then carefully tape edges. Tape paper at least 1 foot from frames to be painted. 2 feet is better to catch overspray.
Spray 2 light coats of Fastline Etching Primer, gray, FA3XEP.
Spray 2 light coats of Rustoleum Professional Aluminum Primer.
Spray 3 coats of Rustoleum Professional High Performance gloss white enamel.
Remove paper and tape, then smile.
