How do you know if Lippage is tile?

2 Answers. Lay a straightedge of a suitable length* across the tile. Use a leaf-type feeler gauge to determine the gap at the widest location. Holding the straightedge snugly to the floor, find the gauge leaf (or combination of leaves) that just fits under with slight resistance when pressed down tight to the tile.

Does grout cover Lippage?

Lippage standards are 1/32″ for grout joints up to 1/4″ wide and 1/16th of an inch for joints over 1/4″ wide. As to adding more grout, making a grout “ramp” from one tile to another is more effective with wider grout joints. Like most things though, if you’re going to do this, the sooner it is done, the better.

Why does Lippage happen?

Lippage is a tile phenomenon that occurs when tiles are not laid uniformly, creating an uneven floor surface that is visible. In some cases, lippage is so extreme that it is visibly noticeable from a distance, as the tiles fail to form a flat surface. In all tile installations, lippage can happen.

What is slab tolerance?

Traditionally allowable tolerances of concrete floor slabs were determined by checking the slab surface with a 10 foot straightedge. Common tolerances were 1/8 inch or 1/4 inch in 10 feet. Depending on where the measurement was made, the slab may pass or fail the specified tolerance.

How do you calculate tile warpage?

Warpage is calculated by dividing the actual measured amount that the tile deviates from flatness by the length of the edge or diagonal, then multiplying by 100 to get a percentage. In the American National Standard for tile manufacturing, ANSI A137.
