What should be checked before floor tile is set?
The floor should be checked for flatness, movement, damage, residue, moisture concerns and height changes before tile is installed.
Floor preparation handles cleaning, flattening and surface readiness. Subfloor prep looks at the structure below. If the floor is uneven, self-leveling compound may be part of the plan.
Skipping those questions can turn a tile choice into cracked grout, lippage or a doorway that suddenly feels wrong.
