Our painter sprayed a primer for latex paint onto our new
smoothly-textured drywall.

After a few days, he sprayed on two (2) coats of a low-sheen latex
enamel.

After drying, the ceilings and walls have a number of areas that are
lower/higher sheen than the rest, as seen by looking along the walls,
ceilings.

Do those areas correspond to where seams in the drywall were taped and mudded?
If so - if the sheen on the drywall is different from the sheen on the mud -
the cause is probably cheap primer, or not enough primer, or both. Since it
was sprayed, it was probably thinned first to facilitate spraying, and
probably should have had two prime coats instead of one.

Is this the inevitable downside of sheen enamel on drywall or could it
be the painter/paint, etc. The painter claims a 3rd coat will fix
everything.

Probably will.

Possibly the sheen contrast will reduce to zero over time, but I'm not
optimistic.

Doubtful.

Not sure what the primer was, but the enamel is Frazee Mirro-Glide.

Any suggestions? Thanks.

Find out what primer he used....
