About 6 months ago I hired a painting contractor to paint a rental
property that I own. The building was painted with white flat latex,
sprayed on. It was a "budget" job, which I am now regreting, as all
of the dust, pollen, etc. sticks right to the paint. The paint was
also put on too thin for my liking.

My question - Can I apply a quality semi-gloss exterior latex directly
on top of the flat latex without priming? The flat latex has a
surface that looks and feels (to me, a non-painter) just about like a
primer. Opinions?

Paint is fine, dirt is not. Powerwash it first, and remove any peeling
paint obviously. Otherwise, flat paint essentially is primer (although it's
not stain blocking of course.)
