Frequently Asked Quentions
1. What's the average cost to paint a 12x12 room?
The average cost to paint a 12x12 room ranges from $400 to $800 for DIY and $1,200 to $2,000 professionally. Our calculator provides exact estimates based on your specific materials, wall height, and surface conditions.
2. How much does epoxy floor coating cost per square foot?
Epoxy floor coating costs $3 to $12 per square foot installed. DIY kits cost $2 to $5 per square foot for materials alone. Professional installation includes surface preparation, multiple coats, and flake systems.
3. How do I calculate how much paint I need?
Calculate paint needs by: 1) Measure total square footage, 2) Divide by coverage rate (typically 350 sq ft/gallon), 3) Multiply by number of coats, 4) Add 10% waste factor. Our calculator automates this with precision.
4. What's more expensive: painting or staining?
Staining typically costs 20-40% less than painting for materials but requires more frequent reapplication. Paint provides better coverage and longer lifespan, while stain enhances natural wood grain with less surface buildup.
5. How much does it cost to hire a professional painter?
Professional painters charge $2 to $6 per square foot or $50 to $100 per hour. Rates vary based on location, project complexity, surface preparation needs, and time of year.
6. Can I paint over stained wood without sanding?
You cannot properly paint over stained wood without sanding. Stain penetrates wood fibers, requiring thorough sanding to create a paintable surface. Use a stain-blocking primer after sanding for best results.
7. How long does surface treatment typically last?
Interior paint lasts 5-10 years, exterior paint 7-10 years, wood stain 2-5 years, epoxy coatings 5-20 years, and waterproofing 3-7 years. Proper preparation and quality materials extend lifespan significantly.
8. What's the cost difference between brush, roller, and spray application?
Brush application costs least ($0.10-0.30/sq ft materials) but is slowest. Rollers balance cost and speed ($0.15-0.40/sq ft). Spraying is fastest but costs most ($0.25-0.60/sq ft) with higher material waste.
9. How much does surface preparation add to the total cost?
Surface preparation typically adds 25-40% to total project costs. This includes cleaning, repairs, sanding, priming, and protection. Skipping proper preparation reduces finish quality and longevity dramatically.
10. When is the best time of year for exterior surface treatment?
The ideal time is spring or fall when temperatures are 50-85°F with low humidity. Summer mornings work if temperatures stay below 90°F. Avoid winter application below 50°F or during high humidity periods.
