TIP when using Heat Stop Premixed.  For best results:

  1. Mix all of the contents in the container thoroughly before using.
  2. If, after mixing, the product still appears dry, add a little clean water and remix it thoroughly.
  3. For firebrick installation, keep the joints 1/16″ to 1/8″ thick.

This product may take longer to dry if the joints are thicker than 1/8″, and/or if conditions are extremely humid (such as after a recent rain).  To enhance the drying in such conditions, open the damper, place a fan in front of it, or use other means to get some air or heat passing by the installation.
