Understanding Tile Lippage
Lippage refers to differences in height between the edges of adjacent tile modules. This variation is defined in the ANSI A108.02 standard.
Several factors can influence the perception of lippage, including the inherent thickness and warpage of the tiles themselves, as well as the spacing between them.
Factors Affecting Lippage Perception
The angle of natural or artificial light can accentuate otherwise acceptable variations in tile height. Highly reflective tile surfaces can also make these variances more noticeable.
Variations in the underlying substrate plane can also impact lippage. When tile is installed using the thin-set method over an uneven substrate, the finished surface may not meet lippage standards.
Tile Warpage and Substrate Plane
The ANSI A137.1 standard defines allowed warpage for tiles. Warpage refers to the allowable deviation from flatness in a tile module.
Uneven substrates are a common cause of lippage, particularly when using the thin-set installation method. Ensuring a level substrate is crucial for a proper tile installation.
Calculating Tile Material Needs
Proper planning is essential for any tiling project. This includes accurately calculating the amount of tile and grout needed to avoid waste and ensure a consistent appearance.
