The product data sheet states the following under directions for use;

To ensure homogeneity shake well before use. Scrape or sweep away grease, oil, dirt and all other surface contamination as much as possible. Degrease by means of alkaline cleaning, high pressure (steam) cleaning or, for small patches, by volatile solvent cleaning. Apply Surfa-Etch 108 Etching Solution liberally and scrub it into the surface with a nylon brush or broom. Allow to stand for 10-15 minutes, depending on temperature, and clean thoroughly by flushing with plenty of fresh water.

Do not allow the Surfa-Etch 108 Etching Solution to dry before rinsing! Concrete and masonry may need a second treatment. After cleaning, remove any remaining water and allow to dry completely, as moisture left on the surface or entrapped into pores may cause failure of the coating system. Large surface areas or poor drying conditions may require longer drying times before a coating system can be applied.

It is not possible to provide an accurate length of time before the floor can be coated as this will depend on many factors such as temperature, air flow, humidity, porosity of the substrate, amount of water used to flush the area, etc. The product you intend to coat the floor with will have a maximum moisture content requirement for the substrate it is to be applied to. A definitive answer could be achieved by taking moisture readings of the floor with specialist equipment and only applying the coating once it has met the desired figure.
