How to Tile a Concrete Basement Floor

Laying your concrete basement floor with tiles such as ceramic tiles is an excellent way to enhance the beauty as well as increase the lifespan of your concrete basement floor. The early application of tiles as floor finish was not as successful as it is today as tiles made before easily breaks. However with new technology applied to the making of tiles, their durability and appearance have tremendously been improved making the use of tiles a favorable option to various flooring repairs. The practicality offered by the use of tiles on a concrete basement floor is its direct installation on the surface without having to make additional structural support.

Step 1: Inspect your Basement Floor for Damages

Inspect your basement floor for cracks, rough surfaces, leaks and any flooring anomalies before installing ceramic tiles. These damages must be repaired first and uneven surfaces need to be thoroughly leveled out in the area where the ceramic tiles will be installed. 

Step 2: Cleaning the Concrete Flooring

Remove all the dusts and debris found in your basement concrete floor using a vacuum cleaner and a broom. Remove stubborn dust and dirt using a mop soaked in a solution of bleach and water. Make sure to mop the entire floor area of your basement as any dirt and dusts present are potential hazards to the success of your tiling job. After mopping, allow your concrete basement floor to completely dry.

Step 3: Preparing the Tiles to be Installed

Decide on the pattern to be installed and dry-set it. With a tile nipper, cut the tiles to the desired size. Then mark the room flooring to make quadrant divisions with horizontal and vertical lines once the tiles have dry-set. This will be the guide to ensure that the tile application will fit the area of the flooring. Take out the tile pieces and be ready to apply the thinset mortar. 

Step 4: Applying the Thinset Mortar

Read the product instructions found at the label of the thinset mortar that you purchased. Different manufacturers have different ways to mix their thinset so make sure to follow the manufacturer’s instruction to the letter. Work with one quadrant at a time on applying the thinset mortar. Put this mixture onto the concrete flooring using the flat side of a trowel. 

Step 5: Setting Down the Ceramic Tiles

The ceramic tiles should now be positioned into the mortar. Securely tap the ceramic tile in its rightful location with the use of a rubber mallet. Spacers should be utilized to act as a barrier for the grout. Finish up filling the whole concrete flooring area and have the mortar fully dry.

Step 6: Applying the Grout and Drying the Area

Per manufacturer’s instruction, the grout should be mixed thoroughly as needed. Take out the spacers in-between the tiles and wipe grout into it and allowed to settle for some time. Remove any excess grout with a soft cloth. The grout should then be allowed to cure which should take a day or two. The tiled concrete flooring can now be walked on.
