[QUOTE=Lumen Miner;486018]I am a bit shocked Gary didn't pick up on the fact that you said "interior" paint. Although his description of the undercoat is adequate, unfortunatley the under coat is not the main reason for painting defects. It is the top coat used. No undercoat will fix, the wrong topcoat.
Hi,
As to cause of painting defects - I respectfully disagree, poor preparation and no top coat will ever be any good. Certainly the choice of top coat must be correct, but put the right top coat on an incorrectly prepared substrate and your screwed.
I didn't worry about the topcoat as his question was about whether he needed a primer. I also reasoned that since it was not going to be left outside and subjected to UV day in and out using a bit of interior would be Ok. Same as most spray can varnishes are interior rated and hence if going down that path and being picky choose an exterior one.
cheers
Gary
