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?

Spackle is a more porous substance than the materials that make up the surrounding wall.

It is important to use primer on the spackle spot prior to painting the wall.
