No sealers or curing compounds should be used on concrete slabs which are to be covered with tile, etc.

Freshly poured slabs should be covered and damp cured for a minimum of seven days; have a broom finish; be true to within 1/4" in ten feet (that is, there should be no more than 1/4" difference in elevation from one end of any ten-foot distance measured to the other end); and pitched to drains, where required.

Areas requiring fill, leveling, or patching, should be prepared using Super-Tek's Super-Flexcote, Super-Patch, or Super-Level. Asphalt-based leveling compounds should not be used.

The surface to be tiled must be left clean, free of dust, grease, oil, sealers and foreign matter.

When in doubt about the surfaces adhesion, prime it with Super-Weld.
