1. Prep the room
Move furniture to the center or out of the room. Cover floors and remaining furniture. Remove outlet covers. Fill nail holes with spackle, sand smooth when dry, and wipe dust off walls.
Painting techniques for a clean finish
A clean paint job is mostly prep and patience. Follow this order so coats lay evenly and lines stay sharp.
2. Clean and prime if needed
Wash greasy or dusty walls with mild soap and water; let dry fully. Prime raw drywall, stains, or big color changes (especially dark to light). Primer improves adhesion and often reduces total coats of finish paint.
3. Cut in first
Use a 2–2.5 inch angled brush to paint a 2–3 inch band along ceilings, corners, trim, and around openings. Work in sections so you can roll while the cut-in edge is still wet ("keeping a wet edge").
4. Roll walls in a W or M pattern
Load the roller evenly (not dripping). Start a few inches from a cut-in edge, roll a large W or M, then fill without lifting the roller. Work top to bottom in 3–4 foot sections. Avoid pressing hard — let the roller nap hold the paint.
5. Apply a second coat
Most walls need two coats for even color and durability. Wait until the first coat is dry to the touch (often 2–4 hours for eggshell/satin; check the can). Sand lightly only if you see raised grit or brush marks.
6. Finish trim and cleanup
Paint trim after walls if walls are the new color (easier to cut a clean line). Remove tape before paint fully cures. Wash brushes and rollers promptly; store leftover paint sealed and labeled for touch-ups.
Pro tips
- Buy enough paint for two coats up front — running out mid-coat creates a hard edge that is hard to hide.
- Paint ceilings before walls when doing both.
- Good light matters: use daylight or a bright work light to spot holidays (missed spots).
- Humidity and cold slow drying — follow the label for recoat windows.
Know gallons before you roll
Two coats only work if you bought enough paint. Get your exact gallon count, then optionally email yourself an advanced product recommendation.
