Exterior Concrete Substrates

(Also see Concrete and Other Exterior Substrates)

Tiling an exterior concrete patio can help transform a backyard into a fun outdoor living space for relaxing or entertaining. Exterior concrete substrates that are not even should be corrected using a quality exterior concrete repair product.

All exterior concrete substrates should be clean, dry and free of dust, dirt, oil, grease, paint, tar, wax, soap, concrete curing compounds, concrete color stains, concrete sealers, clear coats, loosely bonded toppings, any primers that are not MAPEI brand, old adhesive residues (unless otherwise recommended by MAPEI), and any other substance that may prevent, reduce or affect adhesion or performance.

Concrete patios, driveways and balconies should be sloped so that water drains off the area and no large puddles of water are left over after rain. When no slope is present, MAPEI recommends hiring a professional to create the required slope using an appropriate exterior-rated cement-based product.
