Choosing the Right Dur-A-Glaze in Cooler Temps

February 14, 2020

In temperatures below 60 and above 45 degrees Fahrenheit, you can decrease your broadcast cure time by using Dur-A-Glaze #4 Fast Hardener.

  • Use Fast Hardener in the patching, and broadcast coats only.
  • Do not use as a grout/topcoat as yellowing/ambering will occur.
  • Do not use performance topcoats such as Armor Top or Accelera — they will not bond to the Fast Hardener.

For systems requiring a high performance topcoat, you will want to use a Dur-A-Glaze #4 Regular Hardener for your grout coat.

  • If it is below 60 degrees F, know it will take longer to cure (24-36 hours).
  • Do not use Dur–A-Glaze #4 Water Clear Hardener below 70 degrees F. (This product is best used in the warmth 70-90 degrees F).
