About This Material
Paint cost varies significantly by quality tier. Economy paints ($20 to $30 per gallon) like Behr Flat and Glidden Essentials are suitable for rental properties, ceilings, and areas where appearance is not critical — they require more coats and have shorter lifespans. Standard paints ($30 to $40 per gallon) like Behr Premium Plus, Valspar Signature, and Sherwin-Williams SuperPaint offer good coverage and durability for most residential applications. Premium paints ($45 to $55 per gallon) like Benjamin Moore Regal Select and Sherwin-Williams Duration provide superior coverage (often true one-coat hide), excellent washability, and a 15+ year lifespan on interior walls. Ultra-premium lines ($60 to $80 per gallon) like Benjamin Moore Aura and Sherwin-Williams Emerald feature the highest pigment loads, self-priming formulas, and advanced color technology for the most demanding applications. Beyond paint, budget for supplies: a quality roller frame and covers ($10 to $15), angled brushes ($8 to $12 each), painter's tape ($5 to $8 per roll), drop cloths ($8 to $15), paint tray liners ($5), and extension poles for ceilings ($15 to $25). Professional painters typically charge $2 to $6 per square foot for interior painting, which includes labor, paint, and supplies.
Installation Tips
- •Buy all your paint at once to ensure color consistency across the batch.
- •Invest in quality rollers and brushes — they make a noticeable difference in finish quality.
- •Use painter's tape on trim, baseboards, and ceiling lines for clean edges.
- •Keep a wet rag handy to wipe drips immediately before they dry.
Common Mistakes to Avoid
- Choosing the cheapest paint for high-traffic areas — it will need repainting in 2 to 3 years instead of 7 to 10.
- Forgetting to budget for primer — skipping primer on new drywall doubles the topcoat needed.
- Not buying enough paint — matching a custom color later is nearly impossible.
- Ignoring sheen selection — flat hides imperfections but is hard to clean; satin and eggshell are the best all-around choices for walls.
