Finish TradesQuestion 409 of 700
When installing large-format porcelain floor tile, keeping mortar coverage high under the tile is MOST important because it primarily prevents which problem?
a.Excess grout width
b.Color variation between tiles
c.Slippery surface texture
d.Cracking or hollow spots under point loads
Explanation
High mortar coverage (few voids) supports the tile fully so point loads do not crack it or create hollow-sounding spots. Grout width, color variation, and surface slip resistance are governed by other factors like spacer size, tile lot, and finish, not by mortar coverage.
