Fixing a Sloped Concrete Patio: Self-Leveling Overlay vs. Epoxy Resurfacing

A concrete patio sloping toward the house causes water intrusion. Self-leveling mortar can work for minor corrections, but epoxy resurfacing offers more durability and design options.

Self-Leveling Mortar

• Good for 1/4" to 1" thickness.
• Requires precise surface prep (clean, prime, dam edges).
• Follow manufacturer steps exactly—no shortcuts.
• Can crack if substrate moves.
• Broom finish uses long-handle brooms.

Epoxy Resurfacing (Often Better)

• Thin (1/8"-1/4"), bonds tenaciously.
• Can be stamped (flagstone, tile patterns), stained, colored.
• Resists cracking, fading, chemicals.
• Non-slip additives available.
• Professional application recommended.

Material Calculation

Area (sq ft) × desired thickness (ft) = cubic feet. Divide by 27 for cubic yards. Add 10% waste. For bags: check coverage per bag at your thickness.

Critical First Step

Fix the drainage! Re-grade perimeter, install channel drain at house, or add French drain. No overlay lasts if water pools underneath.

Epoxy costs more upfront but eliminates recurring repairs—ideal for sloped patios at house foundations.
