Frequently Asked Questions
How much chalk paint do I need for a piece of furniture?+
Small side table: 1/2 pint. Dresser: 1 pint. Large wardrobe: 1 quart. Chalk paint covers approximately 150 sq ft per quart. Bare wood absorbs more; add 20%.
How many square feet does a quart of wood stain cover?+
Oil-based stain: 150-200 sq ft per quart. Water-based stain: 200-250 sq ft per quart. Gel stain: 100-150 sq ft per quart. Bare wood absorbs more; reduce coverage by 20-30%.
Do you need more paint for porous or bare wood?+
Yes. Bare wood absorbs 20-40% more paint than sealed surfaces. End grain absorbs even more. Use a primer or first coat as sealer. Calculate 1.3-1.5x the area for bare wood.
How do you calculate paint coverage for small projects?+
Calculate total surface area in square feet. Divide by coverage rate (sq ft per container). Multiply by number of coats. Add 15-20% waste. For small projects, round up to nearest container size.
How much polyurethane is needed for a dining table?+
Standard dining table (36×72 inches): approximately 1 pint per coat. For 3 coats: 1 quart. Water-based poly spreads thinner; use 1.5x. Oil-based: 150 sq ft per quart.
How many coats of paint are needed for raw wood?+
Minimum 2 coats for raw wood. First coat acts as sealer. Second coat provides color and protection. For high-traffic surfaces: 3 coats. Always sand between coats.
What is the average coverage of a 2 oz bottle of craft paint?+
A 2 oz bottle covers approximately 4-6 square feet with one coat. For a 12×12 inch surface: about 1/4 of the bottle. Coverage varies by brand, color, and application method.
How do you calculate paint coverage per square inch?+
Convert coverage rate to square inches: 1 sq ft = 144 sq in. For 150 sq ft per quart: 150 × 144 = 21,600 sq in per quart. Divide your project area in sq in by this number.
Does a paint sprayer use more paint than a brush?+
Sprayers can use 20-30% more paint due to overspray. HVLP sprayers are more efficient (10-15% waste). Brushes and rollers waste less but take longer. Factor in application method.
