UltraClear Gap Sealant

Clear, Odourless Sealant for A Draught-Free Home.  

Draught proof your home to stop the entry of outside air and keep your heating and cooling where it counts. Because a draught-free home is a home that’s thermally efficient and cheaper to run.

Seal off those tiny cracks on every nook and cranny of your home with Fuller UltraClear Gap Sealant, the best solution for creating a tight seal on stubborn gaps and spaces.


How it Works:
UltraClear is a water-based gap sealant that is white when applied and clear when dry (not invisible). This virtually invisible sealant is flexible enough to expand and contract with most movement of the building.

Like most sealants, UltraClear is applied to gaps and cracks using a caulking gun to effectively prevent draught. It can be used to effectively seal cracks and gaps around architraves, skirting boards, windows, and air vents.

During the caulking process, excess sealant can be easily cleaned up with a damp cloth when wet.
