I have a finished basement with exposed ductwork that has been previously painted brown and is in bad shape, paintwise. The pain has flaked in some areas. I really don't know what type of paint it is, but sanding to bare metal is definitely out of the question. Last night I roughed up the good areas with sandpaper and then removed all the chipped and flaked paint. I am thinking of priming first (with a spraygun, Graco project painter) with Zinsser Bullseye water based primer, then just spraying with a Satin Latex. I figured the latex paint would be flexible and be able to stand the temperature changes of the ductwork.
Now my question is this - what do I use to seal the seams of the duct work that is paintable? Is aluminum foil tape paintable? Or should I paint the ductwork first, then just get a white DUCT tape (not the foil stuff)?
I found this foil tape that claims to be paintable (but it is the only one that says it is paintable):
If you need pictures, let me know.
