Got another renovation problem...
There were some bullet holes - well, holes - in my walls that mostly weren't
too bad so I spackled and sanded the spackle to even. The paint job over
the spackle doesn't look right, though. Is there a substance I should have
appiled over the spackle before painting?
Primer will usually do the trick. I bet you're referring to how smooth the
paint looks over the spackle and the rest of the wall has the texture from
the roller, right? Hit those areas again with the roller and it will build
up the texture from the knap of the roller - it may take a couple of times.
Some things to look at:
-Texture: There might be a slight texture difference between the
spackled area and the rest of the wall. Apply primer and dab at it with
a rag or swipe with a drywall knife, etc. Whatever it takes to make it
look like whatever was done to the rest of the wall.
-Shrinkage: Spackle will shrink just a bit when drying - not like wall
board joint compound, but a bit nonetheless. Apply more Spackle proud
of the wall, let dry thoroughly, and sand smooth.
-Backing: If the hole is not all the way through the wall (e.g. you
have plaster screen or more wood to which the holy wall is mounted), you
should not have a problem here. Wooding siding or dry wall could stand
something to back up your patch. Wadding a bit of newspaper into the
hole (or something fire resistant!) will provide that. Some sort of
plug wedged in just shy of the surface is another way.

Here's the long answer:
You are probably seeing "flash" from the texture difference. Some lighting
can make this difficult to hide without doing a skim job or level 5 finish.
On my last project, I used water based primer. During rolling, the roller picked
up the dusts and pulled off the spackle. That left the edges full of small pits.
When the primer dried, the patch shrinked. It was nice and flat before priming.
I would probably opt for spray on oil based primer next time. Water based roll
on primer messed up badly.

it was your application technique; not the product that
resulted in problems, Sean. Zillions of gallons of water
based primer are applied over fresh spackling and drywall
mud without incident. the fact that the patch shrank AFTER
you applied primer indicates you didn't let the patch cure...

PVA, polyvinyl acetate. It is a primer used on spackle. When you
are filling and repairing with spackle, check your work using a
trouble light against the wall before thinking about any paint--you'll
see your mistakes!
That's wood glue, should you not have the primer available. Dilute 1:5 for
If you have a sponge handy, you can use it for "texturing" a bit while
feathering by blotting the surface of the spackled area.
