Primer questions
 
I have used spackle to repair wall damage. I will be repainting the walls with the same color (very close to it). The paint I am going with is a paint+primer. Will two coats of such a paint conceal the spackled spots well enough?

Or do I have to use a separate primer first? If I use a primer first, is it a MUST to sand the primed wall before applying the paint?

Thanks in advance.

Paint and primer in one is a scam.
Make 100% sure there repaired areas are perfectly smooth. Run you hand over it.
No paint or primer is going to fix flaws.
You Zinsser 123 to prime then two coats of quality paint.

Thanks for the quick reply.

Is it ok to paint directly over the primer without sanding first? I'd like to avoid the effort of sanding if possible.

Thanks

Actually 2 coats of paint+primer often will cover patches. What is the sheen - flat, eggshell....? I would definitely sand the. You don't normally have to sand the primed areas if you don't want to.

I am thinking of going with eggshell but can switch to flat if that's better in this case.

You should put on what you really want in the end. Just keep in mind:

- flat: hides flaws in the wall better, usually don't need to prime patches, easier to touch up later, but harder to scrub and keep clean.

- eggshell: shows wall and patch flaws more, must use multiple coats and/or a primer to cover patches, harder to touch up later, easier to scrub and keep clean.

If it were my project, I'd definitely roll primer on the spackled spots before painting them. Maybe two coats.

Primer & paint in one does NOT do the same thing that priming first, then painting, does.

Might want to check out the search function to read the dozens of people dealing with trying to paint with no primer and the paints flashing and the repaired areas are still showing.

You still need to prime or at the very least double coat with finish paint patches even when using flat paint.

To answer the question, no, you do not need to sand the primer

I plan to only put primer on the spackled areas. After two coats of paint will there be a noticeable contrast between the primered and nonprimered areas?
I.e do I need to put primer on the entire area?

Thanks

You only need to prime the patched areas. After primer and 2 coats of paint the spots should blend with the rest of the wall.

I would just prime the spackled areas, and "feather" out the edges. It takes just a little finesse, but you'll have no problem doing it.

Back to the topic at hand. Whenever possible primer is always best for any patchwork. Sometimes it is not feasible to use primer for just a couple spots. If that is the case then use your finish paint as a primer. And no, finish paint is not a primer. Paint the patched spots and allow it to dry, then your 2 follow-up finish coats on the entire wall should make the patched areas match the surrounding area. One coat of flat paint is never going to work over any patched areas. It “may” look ok straight on but it will stick out like a sore thumb when viewed at an angle. You are not just matching the color, you have to build up the texture to insure uniformity.
