As I travel around the country, I continue to hear the same statement no matter where I go. The statement goes something like: “The general contractor won’t pay for prep work” or the statement from the GC is “Just get it done, it will be fine.”
Well in most cases, it will not be fine and neither the owner nor the general contractor will accept the completed work. Surface prep, whether for the wall or floor, is critical to the completed job being acceptable to the end user. If the substrate is not flat, the finished surface will mirror the irregular substrate—which is especially true when ceramic tile is installed over concrete block walls.
