Suitable substrates include but are not limited to permanently dried concrete and wood.
To eliminate the telegraphing effect of defects in the substrate through the flooring, the substrate must smooth.
Remove all dust, dirt, grease, and foreign materials from the substrate.
Moisture in the substrate negatively affects an adhesive product and should be eliminated prior to installation.
CAUTION- cinder fill, vermiculite, pumice and other aggregates which are hygroscopic in nature cause the concrete to be very slow drying. This type of concrete will easily absorb excessive moisture from the atmosphere and other sources. Any concrete curing compound must be completely removed.
