1980 Aluminum Siding - Cleaning for Paint
Posted: Sun Oct 15, 2017 9:34 pm
Hi, I have a 1980 SW. It has never been painted to my knowledge. The aluminum siding is in ok shape, no rust or dents, but I do want to paint it.
So when I started washing it, I just used a 5 gallon bucket of water with some bleach in it (for algea) and a long handled brush. The algea came off fine, but so did a lot of pigment? Old paint? Not sure what it is, but the water ran in the color that was on the siding: white for the top third, and tan for the middle stripe.
I'm just wondering, do I have to get all that stuff off, like wash until water runs clear? Or can I do a basic wash with a pressure washer and leave it at that? I was planning on using BIN Primer.
Thanks for your help!
