MIXING

Thoroughly stir the entire pail of Liquid Flashing SW, Liquid Flashing WW, SarnaRoof Liquid Flashing Color Base, or Liquid Flashing Primer at a slow speed (200 – 400 rpm) using an electric drill with a stirring paddle for two minutes.
After stirring, pour 1 liter of Liquid Flashing into a clean plastic container and then add the appropriate amount of Liquid Flashing Catalyst (see below). Mix at slow speed using an electric drill and a disposable mixing paddle for two minutes. Do not re-use the mixing paddle after mixing the Liquid Flashing product and Liquid Flashing Catalyst.
The amount of Liquid Flashing Catalyst used may be altered depending on the ambient and surface temperatures. The mixing rates shown below are based on the mid‐range temperatures to provide an approximate pot life of 10 – 15 minutes after mixing.
