What is the proper method of installing over minor cracks in a slab?
UNIFLEX 916 or ULTRACURE 971 have elastomeric or stretchable properties to suppress seasonal opening and closing (1/16) of cracks that often damage/split ceramic tiles or natural stones set with conventional setting mortars. This excludes cracks or joints in slabs that move in a hinge, stair-step, twist/cant or relieve building movement (i.e. expansion joint, saw-cut joint, control joint, etc).
