About Paint

Paint Coverage

Most quality paints cover 350 square feet per gallon on a smooth surface. Coverage varies based on surface texture, color changes, and application method.

Paint Types

• Latex (Water-based): Easy cleanup, low odor, fast drying, good for most interior walls
• Acrylic: Durable, long-lasting, great for exterior use
• Enamels: Hard finish, great for trim and cabinets
• Specialty Paints: Primers, semi-gloss, high-gloss for specific applications

Number of Coats

• 1 Coat: Touch-ups and refreshing existing color
• 2 Coats: Standard recommendation for optimal coverage
• 3+ Coats: Dramatic color changes or premium finish

Paint Cost Estimates

Budget $25-50 per gallon for quality interior paint, $30-60 for exterior. Premium brands cost more but last longer.

About Roofing

Roof Pitch Impact

Steeper roofs require more materials due to increased surface area. The pitch multiplier accounts for this slope factor.

Shingle Types

• Asphalt Shingles: Most common, affordable, 15-20 year lifespan
• Wood Shingles: Beautiful, natural look, requires maintenance
• Metal Roofing: Durable, energy-efficient, 40+ year lifespan
• Composition Shingles: Mix of materials, good value

Roofing Measurement

Roofing is measured in "squares" - 1 square = 100 square feet. Most shingles cover about 3 squares per bundle.

Roofing Cost Estimates

Budget $3-5 per square foot installed. Asphalt shingles are cheapest; metal and premium options cost more.

About Flooring

Flooring Types

• Tile/Ceramic: Measured in square feet, durable for kitchens and bathrooms
• Laminate: Budget-friendly, measured in planks or boxes
• Hardwood: Premium option, measured in board feet
• Vinyl Plank: Waterproof, durable, measured in planks

Waste Factor

• 5%: Simple layouts, rectangular rooms, minimal cuts
• 10%: Standard for most projects
• 15%: Complex layouts, diagonal patterns, irregular shapes
• 20%: Intricate patterns, many cutouts, shaped rooms

Installation Considerations

Professional installation adds $3-8 per square foot. DIY installation requires proper tools and patience but saves labor costs.

About Drywall

Drywall Sheet Sizes

• 4x8 (32 sq ft): Standard, most common, easy to handle
• 4x12 (48 sq ft): Faster installation, fewer seams, heavier
• 4x16 (64 sq ft): Professional installations, requires equipment

Drywall Thickness

• 1/2 inch: Standard for most residential
• 5/8 inch: Fire-resistant, better sound control
• 1/4 inch: Repairs, curved surfaces, underlayment

Drywall Supplies Needed

Joint tape, joint compound ("mud"), screws, and primer/paint. Budget 1 gallon joint compound per 150 sq ft of drywall.

Installation Labor

Professional installation runs $1-2 per square foot. DIY requires skill but saves significantly on labor.

Material Coverage Reference

Note: Estimates based on standard applications and 2 coats of paint. Actual quantities may vary.
