Options for Relining a Chimney
As there are various levels of disrepair of a flue, there are also various options for restoring it, ranging from filling in gaps in the mortar, to resurfacing with a ceramic flue sealant, to a complete relining with either a stainless-steel liner or a ceramic-steel sleeve sandwiched between two coats of flue sealant.
Mortar joint repair
If your flue has gaps in the mortar between tiles, HeatShield® Cerfractory® Flue Sealant can restore it. A custom foam applicator blade fits your chimney, positioned below each gap. The HeatShield® mixture fills voids, extruded by the tool, leaving a smooth repair.
Flue resurfacing
- For chimneys with cracked or spalled flues that are otherwise sound, the Resurfacing System is used to apply a coating over the entire flue. After that, a custom-made foam applicator plug is placed at the bottom of the flue and attached to a winch on top of the chimney. Subsequently, a “tie coat” material is applied to the flue walls as the plug is pulled upward by the winch. Following that, this cleans any remaining dust in your flue and acts as a primer for the flue sealant. Additionally, the HeatShield® material is applied onto the flue at a thickness of about 1/4″ with the foam plug as it is pulled upward by the winch. Then, this unique application method is known as “slip casting” or “slip cast extrusion.” Eventually, the HeatShield® Installer verifies that your newly restored chimney is completely sealed and smoke-tight by video scanning your completed repair.
CeCure® Sleeve relining
- In chimneys with more serious defects or unlined chimneys, HeatShield® can be used with the CeCure® Sleeve Relining System. The CeCure® Sleeve is a thin-profile ceramic insulation reinforced with stainless steel fabric that is sandwiched between two coats of HeatShield® Cerfractory® Flue Sealant. Afterwards, Your HeatShield® Installer will then use a video camera to verify that the CeCure® Sleeve has been completely coated, ensuring the integrity of your newly relined chimney. In most cases this is a much more affordable option than installation of a stainless steel liner.
