Types of Concrete Patios
Plain (broom finish): Standard gray concrete with textured broom finish. Most affordable option. Cost: $6-$12/sq ft installed. Slip-resistant when wet. Can be stained or painted later.
Stamped concrete: Textured to mimic stone, brick, slate, or wood. Stamps pressed into wet concrete. Wide variety of patterns and colors. Cost: $12-$25/sq ft installed. Most popular decorative option.
Stained concrete: Acid or water-based stain applied to cured concrete. Translucent color with natural variation. Cost: $8-$16/sq ft (new pour + stain). Can be applied to existing concrete: $2-$5/sq ft.
Exposed aggregate: Surface concrete washed away to reveal decorative stones. Natural, textured appearance. Excellent traction. Cost: $10-$18/sq ft installed.
Polished concrete: Ground and polished to a smooth, glossy finish. Modern, industrial look. Cost: $8-$15/sq ft. Best for covered patios (slippery when wet).
Colored concrete: Integral color mixed into concrete before pour. Consistent color throughout slab. Cost: $8-$14/sq ft installed. Add $1-$3/sq ft over plain concrete.
Design and Sizing
Common patio sizes: Small (dining for 4): 10x10 to 10x12 feet (100-120 sq ft). Medium (dining + seating): 12x16 to 14x14 feet (192-196 sq ft). Large (outdoor living room): 16x20 to 20x20 feet (320-400 sq ft). Extra large (entertaining): 20x24+ feet (480+ sq ft).
Thickness: Standard patio: 4 inches. Heavy use or hot tub: 6 inches. Vehicle traffic: 6 inches with rebar reinforcement.
Reinforcement: Wire mesh: standard for residential patios. Rebar: for heavy loads and larger slabs. Fiber mesh: added to concrete mix for crack resistance.
Drainage: Minimum slope: 1/4 inch per foot away from house. Prevents water pooling. French drain at patio edge for large slabs.
Finishing Options
Broom finish: Broom dragged across wet surface. Creates slip-resistant texture. Most common and practical. No additional cost.
Stamp patterns: Ashlar slate: most popular stamped pattern. Cobblestone: European look. Wood plank: mimics wood deck. Herringbone brick: classic. Large stone: natural stone appearance.
Color options: Integral color: mixed in (most consistent). Color hardener: broadcast on surface (richer color, harder surface). Stain: acid or water-based (translucent, natural). Paint: surface coating (least durable).
Sealer (recommended): Protects from stains, moisture, UV damage. Enhances color (wet look or matte). Apply every 2-3 years. Cost: $0.50-$1/sq ft per application.
Cost
Per sq ft installed: Plain broom finish: $6-$12. Colored: $8-$14. Stained: $8-$16. Stamped: $12-$25. Exposed aggregate: $10-$18.
By project size: Small patio (100 sq ft): $600-$1,200 plain or $1,200-$2,500 stamped. Medium patio (200 sq ft): $1,200-$2,400 plain or $2,400-$5,000 stamped. Large patio (400 sq ft): $2,400-$4,800 plain or $4,800-$10,000 stamped.
Additional costs: Demolition of old patio: $2-$5/sq ft. Gravel base preparation: $1-$3/sq ft. Permits: $50-$300. Sealer application: $0.50-$1/sq ft.
DIY savings: Plain concrete is DIY-possible for small patios. Save 30-50% on labor. Stamped concrete requires experience (not recommended DIY). Requires: forms, gravel, concrete delivery, finishing tools.
