Title: Repainting ETC S4's
Post by: Frank Czar on January 10, 2018, 06:19:39 am
Hey Guys,

I have 16 ETC S4's that are showing their age, some of the paint has started to flake off with a white corrosion on the S4.  I would like to paint them. I have before with a combination of sandpaper, wire brush/wheel done this before with other lekos but was looking for any other less labor intensive alternatives. Has anyone used any type of sand/media blast or a chemical strip?

Thanks in advance

Aluminum is not easy to paint - it actually oxidizes very quickly after sanding (minutes) which affects paint adherence.  You will want an “etching primer” to cut through that before painting.  Both primer and paint need to be rated to at least 400 degrees.

I don’t have any insight into chemical methods of stripping.  Sand blasting can work, but it will significantly pit the soft aluminum, so unless no one will ever see the fixtures from closer than 20’ and you’re willing to forego any resale value, I’d stick to sanding.
