On a large-format porcelain tile floor, lippage (one tile edge higher than the neighbor) is a common complaint. Which practice BEST minimizes lippage?
a.Using a leveling/lippage-control clip system and checking substrate flatness before setting
b.Setting tiles as fast as possible with minimal mortar
c.Using extra-wide grout joints only
d.Choosing the most warped tiles first
Explanation
Lippage is controlled by a flat substrate, proper mortar coverage, and mechanical leveling (lippage-control) clips that hold adjacent edges even until the mortar cures. Rushing with thin mortar, relying only on wide joints, or using warped tiles make lippage worse.
