I have never painted vinyl siding......too afraid of a paint failure due to the lack of adhesion and expansion and contraction. Done tons of aluminum siding over the years, but I know aluminum is a much different material when it comes to painting. I recently bought a used pre fab garage that is vinyl sided and needs some TLC(paint job)
to really match it to my house color and make it look decent. Any tips from somebody here who has done it? I know pressure washing would be the first step, but would an acrylic bonding primer(STIX or equivalent) be needed? or just a high quality waterborne or acrylic house paint do the trick?
