Painting galvanized sheetmetal flashing & gutters require a little bit of "prep" work before the painting begins. I know it's not what you wanted to hear but "good prep"...."good paint job". If you paint your galvanized sheetmetal flashings & gutters "before" the proper steps.....then prepare yourself for a shocker. You don't want this to happen to you so here's what you're going to do:
* You will notice that your galvanized sheetmetal flashing(s) &/or gutters has an "oily" substance on it. This oily substance needs to be cleaned off before painting since your paint would vertually "slide off". Use a de-greaser cleaner of some sort. Wipe it on then wipe it off.
* It's now time to apply some vinegar to the galvanized sheetmetal flashings/gutters. Why? Because I said so that's why.....just kidding......this will clean any remaining oils or cleansers that may still be on there but more importantly, the vinegar (believe it or not) will "etch" the surface of the galvanized sheetmetal flashings/gutters thereby letting the primer & paint "stick & adhere" to the clean metal surface......pretty cool huh?
* Now you're ready to apply an exterior grade primer to the sheetmetal flashings/gutters (your "friendly neighborhood" paint store will help you determine what primer is best). One coat of primer will do.
* Applying 2 coats of finish paint to the sheetmetal flashings/gutters is the way to go when finishing your project (oh by the way...use a miniroller where able). And again....your "friendly neighborhood" paint store will be glad to help you decide what paint type & color you may need.....just ask.
* Painting galvanized sheetmetal flashing & gutters can be a "fun" project if......you know the right steps.
* That's it. Sounds like alot of work but the "finish is in the prep" so if you want a great looking outcome to your project then you've got to do your time & follow the right steps. Hey, you can pay a painter to do it or you can do it yourself.....& save.....& it will still look like a pro did it! What could be better?
