- • Premium interior paint (eggshell for walls)
- • Spackle
- • Painter's caulk
- • TSP substitute cleaner
Step-by-step
- 1
Clear and protect the room
Move furniture to the center and cover with plastic. Lay canvas drop cloths on the floor — plastic is slippery and paint pools on it. Remove outlet covers and switch plates.
- 2
Wash, patch and sand
Wipe walls with a damp sponge, especially above the stove and in bathrooms. Fill nail holes with spackle, let dry, then sand smooth with a fine sponge. Caulk any gaps between trim and wall.
- 3
Tape the trim
Run painter's tape along baseboards, window casings and door frames. Press the edge down firmly with a putty knife — that's what prevents bleed.
- 4
Cut in with a brush
Cut in a 3" band along the ceiling, corners and trim using the angled sash brush. Work in 4–6 ft sections so the cut edge stays wet when you roll into it.
- 5
Roll the walls
Load the roller until it's saturated but not dripping. Roll a large W or M pattern in a 3x3 ft area, then fill it in with light, parallel strokes. Always finish each section rolling top to bottom in one direction.
- 6
Apply coat two
Wait the full recoat time on the can (usually 4 hours). Repeat cut-in and roll. Two thin coats always beat one thick coat.
- 7
Pull tape and clean up
Pull the tape at a 45° angle while the last coat is still slightly tacky — that gives the cleanest line. Wash brushes and rollers immediately; dried latex paint destroys tools.
