Yes. The purpose of primer is to seal the raw plaster/gypsum/drywall and create a better surface for finish paint that won’t soak it up. As long as the rest of the wall is properly cleaned before painting (paint doesn’t bond well to dirt, grease, etc), your finish coat should look even and consistent.

Will primer hide drywall imperfections?
The texture of your primer will significantly impact how well you’re able to cover drywall imperfections. If you’re looking for an incredibly smooth finish, using a high-build primer is a must.

Can you paint directly over spackle?
Go over the repaired area just as you would any other area. The texture and color should match perfectly, once everything has dried.

Can you paint directly over joint compound?
Priming the wall seals the joint compound, which has a different texture than the rest of the wall and absorbs more paint than the drywall. Priming blends the joint compound and the drywall, so the surface is uniform. Use a primer designed for painted walls. Apply with a paint roller and use a brush for smaller areas.
Do you have to put primer over spackle?
