The single biggest factor in how a paint job looks at the end is how the drywall was prepared at the beginning. Paint does not hide flaws — it accentuates them, especially under modern LED lighting and large windows. This article walks Jonesboro AR homeowners and DIY painters through how professionals prep drywall for paint and what to look for if you are hiring it out.
Step 1: walk the wall under raking light
Hold a strong light at a low angle to the wall and walk slowly down its length. Every dimple, ridge, screw pop, and taping flaw will jump out under raking light. This is the inspection that should happen before any priming. Mark every flaw with painter's tape and address them before continuing.
Step 2: fill and sand any remaining flaws
Apply a thin coat of lightweight compound to any marked flaws, feather wide with a 10–12 inch knife, let dry, sand smooth. Repeat as needed until the raking-light inspection comes back clean. This step is where DIY paint jobs usually fall short.
Step 3: pole-sand the entire wall
Even walls that look smooth benefit from a light pole sanding to knock down any minor surface inconsistencies and to give the primer something to bond to. Use 220-grit sandpaper. Vacuum afterward with a HEPA vacuum, then wipe down with a damp microfiber cloth to remove fine dust.
Step 4: prime with the right primer
New drywall and fresh patches need primer — paint over bare drywall will absorb unevenly and show every patch and taping line through the finish coat. Standard PVA drywall primer works for most situations. Stain-blocking primer (oil- or shellac-based) is required for water-stained areas, knot bleed-through, or any darker existing finish. For Level 5 surfaces, a high-build primer that helps fill micro-imperfections is worth the premium.
Step 5: inspect again under raking light
After priming dries, run the raking-light inspection one more time. Primer often reveals flaws the bare drywall hid. Mark any new flaws, patch, sand, spot-prime, and re-inspect.
Texture considerations
If the wall has texture (knockdown, orange peel), the primer step is even more important — paint absorbs unevenly into texture and any unprimed area will show. Use an extra coat of primer and roll texture surfaces with a thicker nap (3/8 to 1/2 inch) to fully coat the texture surface.
Paint sheen and wall prep level
The shinier the paint, the more critical the wall prep. Flat and matte paints forgive minor flaws; satin reveals more; semi-gloss and gloss reveal everything. For semi-gloss and gloss applications, prep to Level 5 and prime with a high-build product or you will be unhappy with the result.
Tools and materials professionals use
Pole sander with 220-grit paper, HEPA vacuum, microfiber cloths, lightweight all-purpose compound, 10–12 inch knife, PVA or high-build primer, 3/8-inch nap roller for smooth walls or 1/2-inch for texture, angled brush for cut-in. Skipping any of these tools shows in the finished work.
When to hire it out
If you have a great room with large windows, a hallway with raking light, or any wall that will receive semi-gloss paint, the prep work is genuinely difficult and worth hiring out. For smaller bedrooms with flat paint and forgiving lighting, DIY prep is reasonable if you are patient.
