Step-by-Step Guide
Prep the Room
Remove furniture or move to center and cover. Remove outlet covers. Fill holes with spackle, sand smooth when dry. Clean walls with damp cloth. Apply painter's tape to trim, ceiling edges, and windows.
Prime if Needed
Prime if: walls are stained, patched, new drywall, or changing from dark to light color. Use paint + primer combo for most repaints.
Cut In Edges First
Use a 2-inch angled brush to paint a 2-3 inch border around edges, corners, trim, and ceiling line. This is called 'cutting in.' Work in 4-6 foot sections.
Roll the Walls
Load roller with paint, roll off excess on tray. Apply in a W or M pattern, then fill in without lifting roller. Work in 3×3 foot sections. Apply two coats, waiting 2-4 hours between.
Frequently Asked Questions
How much paint do I need?
One gallon covers ~350-400 sq ft with one coat. Measure room: (height × perimeter) - windows/doors = wall area. For two coats, double the amount. Buy a little extra for touch-ups.
What's the best paint finish for walls?
Eggshell or satin for most rooms (easy to clean, hides imperfections). Flat/matte for ceilings and low-traffic areas. Semi-gloss for kitchens, bathrooms, and trim.
How do I avoid roller marks?
Keep a wet edge (don't let sections dry before blending). Use quality rollers with appropriate nap (⅜" for smooth walls, ½" for textured). Don't overload the roller with paint.
