paints. think the trick might been to solvent clean and maybe sand a
bit. suspect the pvc has a mold release agent on it (maybe?). Spray
paint with it strong high solvent based seems to work well.
Ditto that, except I don't think ultra clean or anything special is needed.
If it's too shiny to take paint easily, sand lightly and wipe/blow the dust
off. Spray is easiest, if it works for your situation. If you do it by
hand, use a foam brush or pad instead of bristles. Apply it any reasonable
way you can, but come back and "sponge" it to finish this (primer) coat.
Relatively even coverage is close enough. When it's bone dry, do another
coat. In this situation, no matter how you apply it, or what type of paint
you use, two coats will outlast one by a gazillion years, or until your
house needs repainted, whichever comes first.
The secret is to prep with a primer containing talc. It costs more than the
paint. Of course, you will want to topcoat with a high quality paint as
well. Sherwin-Williams will have what you need. Just tell them you need to
prep PVC for paint............................
Of course, If I were you, my big worry would be that the soffit flexes too
much for *any* paint.
Go to a real Paint store like sherwin williams and get a primer they
recommend and follow instructions. XIM has been "The" plastic primer
for near 30 years, I use it on all plastics that can be painted, XIM
has an expiration date on the can so read it that you dont get old
stock. PVC inside I have cheated without primers and had good results,
but this is outside so do it right.
