Uses

Xtrabond® HT can be used for a variety of applications including, but not limited to, sealing around heating elements, furnace vent pipes, industrial ovens, smoke stacks, engine parts, fireplaces, HVAC, etc.

Direction for Use

• For best results, prepare a clean surface
• Cut nozzle to desired bead size
• Apply with caulking gun, forcing sealant onto the substrate, then tool if needed
• Clean excess material with mineral spirits or similar solvent

Surface Preparation

• The substrate must be clean, dry, frost free, sound, and free of any oils, grease or incompatible sealers, paints or coatings that may interfere with adhesion.
• Do not apply if surface is damp or contaminated.
• It is recommended all substrates are tested prior to application.
• Primers are not required for most substrates.
