Where would flexible sealant be used in place of grout?
A flexible sealant should be used where tile work abuts restraining surfaces (e.g. perimeter walls, dissimilar materials, curbs, columns, pipes, ceilings, and where changes occur in backing materials) and to honor all changes of plane, expansion, control, construction, cold, and seismic joints. Allowance for movement, using a suitable sealant product, helps prevent or minimize damage caused by structural movement and by loads placed on the structure.
