Product Spotlight: INSUL STICK

March 1st, 2017

Insul Stick is ideal for use in smooth parging over firebrick in the fireplace smoke chamber. With its combined insulating value and strength, Insul Stick meets the strict ASTM E-136 requirements for sealing walls for utility passthrough.

Insul Stick is very versatile in nature and can be cast, parged, troweled, or sprayed.

It is typically used to cast special shapes for:

  • wood stoves
  • fireplace hearths
  • walls
  • boilers
  • furnaces
  • and other high temperature applications.

When using Insul Stick, add clean water (¾ to 1 qt.) for each 5 pounds of product and mix thoroughly. For best results, Insul Stick should be applied no thinner than ¼ to ½ inch thick. When applied correctly, approximately 2.5 pounds of product will cover one square foot.

Insul Stick will stick to virtually any non-slippery surface and will strengthen any wall. Click here to watch our instructional video on Parging with Insul Stick.
