Painting a Room Like a Professional
Paint a room with clean lines and smooth coverage. This guide covers prep, cutting in, rolling, and clean up.
Choose paint and calculate quantity
Pick the finish and color. Measure wall area and buy enough paint for two coats.
Most walls need two coats for even color.
Protect the room
Move furniture to the center and cover floors. Remove switch plates and hardware.
Label plates so they go back to the right spots.
Clean and repair walls
Wash greasy areas, fill holes, and sand smooth. Dust the walls before painting.
Painting over dust causes a rough finish.
Prime where needed
Prime repairs, stains, or bare drywall. Let it dry fully before paint.
Tinted primer helps with strong color changes.
Cut in edges
Cut in around ceilings, trim, and corners with an angled brush. Work one wall at a time.
Feather the edge so it blends with the roll.
Roll the first coat
Use a roller to cover the wall in a W pattern, then fill it in. Keep a wet edge to avoid lap marks.
Do not overwork the paint once it starts to set.
Roll the second coat
Let the first coat dry, then apply a second coat. This evens the color and sheen.
Follow the dry time on the can.
Clean up and reinstall
Remove tape while the paint is slightly tacky. Reinstall plates and clean tools.
Let the paint cure fully before heavy cleaning.
