Five numbers worth remembering

  • Spray when the sheen is gone. Not before, and within minutes, not hours.
  • 200 ft² per gallon is a common data sheet rate and the ASTM C309 test rate. Your product may differ.
  • 3 hours. Rain within 3 hours of spraying means re-spray.
  • 7 days of curing as a common minimum.
  • 72 hours. Run a bond test for at least this long before laying flooring on a slab that had compound.

Tools that do the math

The coverage calculator turns slab size into pails. The product chooser asks up to three questions about the job and points you to a type. The VOC table shows the limit where you are working.
