Examine the Surface

Prior to contracting for a job or awarding a project- the contractor must conduct a survey of the concrete surface in its current shape.

If excessive laitance is present (a weak layer of cement and fines on the concrete surface), this material must be removed down to solid concrete. The coating or overlay will not bond properly to the weak layer of concrete.

The surface should be checked for existing sealers, curing materials, grease, oil, efflorescence, and dirt that need to be removed. In short, you want no surprises.
