For chimneys with cracked or spalled flues that are otherwise sound, the Resurfacing System is used to apply a coating over the entire flue. Cameras are used to verify repairs.
To restore your chimney’s flue by resurfacing the interior, a custom made foam applicator plug is placed at the bottom of the flue and attached to a winch on top the chimney.
First, a “tie coat” material is applied to the flue walls as the plug is pulled upward by the winch. The “tie coat” cleans any remaining dust in your flue and acts as a primer for the HeatShield® Cerfractory® Flue Sealant.
After the tie coat dries, the HeatShield® material is then applied onto the flue at a thickness of about ¼” with the foam plug as it is pulled upward by the winch. This unique application method is known as “slip casting” or “slip cast extrusion”.
As your professional HeatShield® Installer, we will then verify that your newly restored chimney is completely sealed and smoke-tight by video scanning your completed repair.
