5 Prep Steps That Make Interior Paint Jobs Look Professional

← Back to Blog

Paint quality matters, but preparation is what separates a paint job that looks great for years from one that starts peeling in months. These are the steps professionals never skip.

1. Clean the Walls

Dirt, grease, and fingerprints prevent paint from adhering properly. Wipe walls down with a TSP substitute or mild detergent before you open a single can.

2. Fill Every Hole and Crack

Use spackling compound for small nail holes and mesh tape with joint compound for larger cracks. Sand smooth when dry. Painting over unfilled holes makes them more visible, not less.

3. Prime Bare Spots and Stains

Fresh patches, bare drywall, and stains need a coat of primer before painting — otherwise they'll show through the topcoat no matter how many coats you apply.

4. Caulk the Gaps

Run a bead of paintable caulk along baseboards, window frames, and crown molding where it meets the wall. This eliminates shadow lines and gives a crisp, finished look.

5. Protect Everything Else

Use high-quality painter's tape, drop cloths on the floor, and plastic sheeting on furniture. Rushed prep leads to paint where you don't want it — and that's the hardest kind to fix.
