Proper vs Improper Tile Setting

As bathroom specialists we often speak with prospective clients about tile selection, waterproofing systems and the proper installation techniques. Tile setting goes hand in hand with bathrooms and when done correctly can add home value and protection from water damage and mold. But, when tile is installed improperly, it can lead to thousands of dollars in damage and can contribute to mold production. Recently we were called into inspect a faulty install that had tile set using what is known as the “spot bonding” technique in a large shower. This technique is often used when tile setters are attempting to place large format tiles onto a surface that has not been properly leveled and plumbed. Tile setters use spot bonding to help place tiles flush and thus avoiding “lippage” or uneven adjacent surfaces.

This technique is a disaster waiting to happen and should not be used in any circumstance. Proper tile setting involves time spent on stud/framing preparation, plumb and level backer installation and proper troweled mortar bed and back buttered tile. Spot bonding weakens adhesion, tile surface strength and over time leads to water penetration and damage in the void areas between thinset. Thinset should be combed with proper notched trowels with a minimum of 90% coverage. In addition proper thinset selection promotes adhesion to the surface of the tile that is set in place.
