Tiling an exterior concrete patio can help to 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-rated concrete repair product such as Mapecem Quickpatch or Planitop 330 Fast.
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 after rainfall. When no slope is present, MAPEI recommends hiring a professional to create the required slope using an appropriate exterior-rated, cement-based product.
