Painting Tips
- Two Coats: Most paint jobs require two coats for even coverage and color depth.
- Surface Prep: Clean, prime, and repair walls before painting for the best results.
- Buy Extra: Purchase 10-15% more than calculated for touch-ups and waste.
- Quality Matters: Premium paints cover better and last longer, potentially needing fewer coats.
