GGCL Guide: How to install porcelain tiles on concrete floor
It has been observed that concrete has proved to be the most stable working platform in the world. Concrete is also the most preferred choice of builders and architects to use as a foundation when laying down the porcelain floor tiles. The concrete foundation adds to the durability and strength of the porcelain floor tiles and ensures that the installation lasts forever. In fact it can be safely said that porcelain floor tiles installed on the concrete foundation can last much longer than the usually one to five year warranty that other floor finishes have.
To start off, apply a layer of primer and paint or any other water proofing, anti-fracture material on the concrete surface. You can use the fine tip paint brush to cover all the nooks and crannies, and roller to cover the majority of the area. Let this dry off for 24 hours. Dry fit the tiles on the floor for the measurement and layout purposes. Mark the tiles that either needs to be cut or trimmed. Use chalk lines to draw the crosshair at the center of the area to be tiled. This is where you would be starting from.
Mix the thinset and let it rest for 5-10 minutes according to the manufacturer’s instructions. With a paddle, apply the thinset on the grid marked crosshair. Carefully place the porcelain floor tile on the thinset and apply even pressure to ensure proper bonding. Repeat the process till all the tiles have been laid down. Next apply the grout between the edges and joints. Let the grout sit for 20 minutes and then use the grout scraper to wipe off the excess grout. Use a clean damp sponge to wipe off the installation. Let the grout and thinset mortar dry for 24 hours before beginning the regular use.
