How To Seal Windows with X-Seal

Of course, you can seal windows with Tec7, but X-Seal was specially developed to be the ultimate sanitary sealant for all challenging areas. Extreme cases where X-Seal is required could include: areas with a very high propensity for mould or bacterial growth, areas that will be exposed to aggressive cleaning chemicals, or intense UV radiation (such as windows!).

Step 1: Preparation

Important for a permanent optimal adhesion:

  • Remove loose dirt and dust with a brush or hoover.

  • Clean the substrate using Tec7 Cleaner and/or Multiclean: apply, leave for a while, rub off with a clean, lint-free cloth and remove residues with a second clean cloth.

Important for a perfect result:

  • Cut the nozzle of the X-Seal cartridge at an angle of 45°. The opening must be slightly smaller than the intended joint.

  • Use a Tec7 Gun, with the black plastic lip at the back facing upwards: when the trigger is released, the piston goes back a little so that there is no more pressure on the cartridge, and the sealant does not run.

Step 2: Sealing

  • Hold the Tec7 Gun at an angle of 45°. So the sealant can always touch both edges.

  • Dispense enough product to fill the joint.

Step 3: Finishing

  • For the finishing, the surface determines the product to be used:

  • Use Tec7 Cleaner on non-porous surfaces such as PVC, metal, hardwood and lacquer.

  • Use HP Clean on porous surfaces such as natural stone, concrete or brick.

  • In case of doubt or combined surfaces, use HP Clean.

  • Moisten a joint spatula (such as the Perfect Finish tool) with the chosen cleaner and smooth the joint off.

  • Remove excess sealant from the joint spatula with Powerwipes. Re-moisten your joint spatula with the selected cleaner.

  • Remove any excess sealant with the cleaner you have already used.

  • Wait around 2 hours before painting over the joint.
