How to use

Sealants

Substrate preparation

If applicable, remove the old sealant cutting it out with a cutter. Then wipe out the remaining marks by using White spirit as helping solvent. The joint should be clean, dry and clear of dirt, loose material and old sealant. Apply masking tape on both sides along the joint in order not to overflow on the adjacent surfaces.

Application

  • Place the cartridge into the silicone applicator.
  • The tip of the nozzle should be cut off as lant (at about 45 degrees) according to the joint width.
  • Apply the adhesive on one of the joint surface by zigzag or small frequent points and wait for 5 minutes.
  • Pull the trigger to apply sealant into the joint. Ensure sealant is applied evenly and has good contact with both sides of the joint.
  • Apply the sealant between 2 adhesive strips, pushing forward to fill the join and make it watertight.
  • Smooth sealant with a smoothing tool within 5 minutes. Remove excess sealant immediately with a smoothing tool or your finger dripped in liquid soap (depending on the product).
  • Remove the tape before the sealant cures. The seal will be perfectly straight and smooth.

CLEANING

Tools and stained surfaces can be cleaned with white spirit before the sealant is cured.
