If marble dust is found at the bottom of the tile, what should be done?

When marble dust is found at the bottom of the tile, it is essential to wash the dust off. Marble dust can affect the adhesion of the tiles and create a poor bond between the tiles and the substrate. If the dust is not removed, it may lead to problems such as tile lifting, cracking, or improper sealing, ultimately undermining the integrity of the installation. Washing it off ensures that the surface is clean, allowing for a better adhesion of adhesives or grouts used in the installation process.

Maintaining cleanliness during tile installation is crucial, as this can prevent future issues with the flooring. Each installation step should check for contaminants that might interfere with the final result, and addressing them promptly ensures a successful and durable flooring project.
