FulaSeal 701 Ultra Clear Gap Sealant | Ultraclear - About

How it Works:

FulaSeal 701 Ultra Clear is a water-based, highly flexible gap sealant that is white when applied and clear when dry. This virtually invisible sealant is flexible enough to expand and contract with the movement of a building.

Ultraclear is applied to gaps and cracks using a caulking gun and effectively draughts around floorboards, architraves, skirting boards, windows and air vents.

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

Suitable For:

  • * Sealing floorboard gaps

  • * Sealing gaps in cathedral ceilings



  • * Ensure the area is thoroughly cleaned before the sealant is applied to ensure thorough adhesion.
  • * Clean up any excess immediately after application. Removal of excess product after Ultraclear has dried is challenging.
  • * If you are sealing really big gaps, you might find that you need a second application of Ultra clear to fill the gap to the same surface level as its surroundings.


Care Instructions:

  • Once applied, there is no “after care” needed but do make sure it is fully dried (cured) before cleaning the area for the first time.
