Glossary: Grout Joint
A **Grout Joint** is the space left between individual tiles, filled with grout paste to seal the subfloor from water, protect tile edges, and absorb minor structural movement.
Grout Spacing Application
Grout joints commonly range from 1/16 inches (for rectified tiles) to 1/4 inches or wider (for quarry or hand-made tiles). Sizing dictates whether sanded or unsanded grout is specified to prevent shrinkage cracks.
