Wall Painting Tips
- Subtract about 20 sq ft per standard door and 15 sq ft per window from your total wall area.
- For an entire room, add up the length of all walls and multiply by the ceiling height.
- Use painter's tape to protect trim, ceilings, and edges for clean, professional-looking lines.
- A coat of primer is essential when covering dark colors with lighter shades or painting new drywall.
- Eggshell and satin finishes are popular for walls as they are easy to clean and hide minor imperfections.
- Roll paint in a "W" pattern for even distribution, then finish with straight vertical strokes.
