Self-leveling underlayments (SLUs) have become increasingly popular as the degree of flatness and smoothness required for floor covering products has increased.
Many projects today call for ever-increasing tile sizes, many of which are rectangular shapes such as 12" x 24", 18" x 36", 24" x 48" and larger, creating difficulties for the installer when bonding the tile to the substrate.
Recently during a CTEF Educational Program, an installation manager for a large company complained that installing movement (expansion) joints in any application is a pain in the butt.
Expansion joints, also known as movement joints or movement accommodation joints, are critical to the success and longevity of ceramic and porcelain tile installations.
