Painting Tips & Guidelines

📏 Accurate Measurements

Measure walls carefully and subtract areas for doors and windows. Add 10% extra for touch-ups and waste.

🎨 Surface Preparation

Clean walls, fill holes, and sand rough spots before painting. Good prep ensures better coverage.

🧱 Primer When Needed

Use primer on new drywall, stained surfaces, or when making dramatic color changes.

🌡️ Weather Conditions

Paint in temperatures between 50-85°F with low humidity for best results and proper drying.

🔄 Multiple Coats

Two coats typically provide better coverage and color depth than one thick coat.

🖌️ Quality Tools

Invest in good brushes and rollers. They hold more paint and create smoother finishes.
