Best Practices for Tiling Onto Concrete Floor

If you decide to tile directly onto a concrete floor, follow these best practices:

Prepare the surface: Clean the concrete thoroughly, remove any debris, and repair any cracks or holes.
Check for moisture: Use a moisture meter to ensure that the concrete has a moisture content below 2.5%.
Apply a moisture barrier: Install a moisture barrier, such as a polyethylene sheet or a latex-based primer, to prevent moisture from seeping through the concrete.
Level the floor: Use a self-leveling compound to create a smooth and even surface for tiling.
Use thinset mortar: Use a thinset mortar specifically designed for concrete substrates, as it provides a strong bond and prevents moisture intrusion.
Grout properly: Grout the tiles carefully to fill any gaps and create a waterproof seal.
