With the increased popularity of larger tile formats in recent years, the necessity for an efficient system to manage lippage issues has grown as well. Lippage is the condition where one tile edge is higher than an adjacent edge, resulting in a finished surface having an uneven appearance. This is a major concern for property owners, as it can be a safety or tripping hazard, as well as being unsightly.
Inherent bowing of tiles can add to the lippage problem, especially the wood-look plank offerings. And increased weight associated with larger tiles can cause tiles to slump.
An effective tile leveling system should be strong enough to align and support large-format and heavy tile surfaces, and have the ability to apply enough force to effectively eliminate bowing while securing tiles in place as the mortar bed dries.
With the advancements in porcelain and compact-surface manufacturing available today, the industry is seeing an enormous increase in the popularity of “thin” tile or gauged porcelain tile panels (GPTP), noted Steve Sprung, Product and Marketing Manager, RTC Products. Installing these panels or slabs not only requires extensive knowledge, but also a certain amount of training and/or certification. The common skill set for standard tile installation may apply, however current tooling will not suffice.
“This introduces our craftsmen to an entirely new segment of tools and installation products,” he explained, “as well as a new standard specification, which can be found within ANSI A108.19 Interior Installation of Gauged Porcelain Tiles and Gauged Porcelain Tile Panels/Slabs by the Thin-Bed Method bonded with Modified Dry-Set Cement Mortar of Improved Modified Dry-Set Cement Mortar. With this written standard, installers now have access to information on methods and best practices to install a material – that until recently – had many unknown factors.”
