Now that all install work is done, the second coat gives the even color. The first coat is always patchy — that is normal.

Step by step
Step 1 of 9
Repair install damage and spot-prime
Walk the walls with a flashlight at an angle. Fill dings, sand flush, spot-prime every patch, and wipe off dust before the final coat.
Step 2 of 9
Tape the trim once the enamel has cured
Tape the trim once the enamel has cured the time on the can (often 24 hours or more) — use delicate-surface tape on fresh enamel.
Step 3 of 9
Cut in the corners, ceiling line, and around windows and doors
Same as the first coat. Brush every edge before rolling.
Step 4 of 9
Roll in 3×3 ft sections, W pattern, then even out top to bottom
No pressure on the final strokes.
Step 5 of 9
Keep a wet edge, one wall in one pass
This is the coat that gives the even color.
Step 6 of 9
Step back and check for misses and drips
Every 2–3 sections, from 6 ft away, at an angle.
Step 7 of 9
Pull the tape at 45° while the paint is still slightly soft
Along the line, not away from the wall.
Step 8 of 9
Put the cover plates back, remove the floor protection
Furniture goes back no sooner than 24 hours. Keep a labeled can of leftover paint for touch-ups. Wash latex tools in water; take the rest of the paint to a paint take-back site (PaintCare in California and several other states) or your city's household hazardous waste drop-off — never pour it down a drain.
Step 9 of 9
Final check with a flashlight at an angle
No misses, no drips, no roller marks, no brush lines in the corners.
Common mistakes
- Second coat too soon. The roller lifts the first coat. Wait the recoat time on the can.
- Pulling tape after full dry. Ragged edge. Pull at 45° along the line while the paint is still slightly soft.
