Essential Aspects to Consider

Before embarking on your tile installation project, it's crucial to consider several essential aspects to ensure a successful outcome:

Concrete Condition: The concrete floor must be structurally sound, free from cracks, and have a smooth, level surface. Any uneven areas or cracks should be repaired before tiling.
Moisture Content: Concrete naturally contains moisture, but excessive moisture can compromise the adhesion of the tiles. The concrete should have a moisture content below 5% before tiling to prevent issues like delamination or cracking.
Flatness and Levelness: The concrete floor should be flat and level to within 1/4 inch over a 10-foot span. Any deviations from this flatness can result in uneven tiles or grout lines.
Expansion Joints: Expansion joints are necessary to accommodate movement in the concrete floor due to temperature changes or moisture fluctuations. These joints should be installed around the perimeter of the room, as well as in large areas or where different flooring materials meet.
