Instructions for use

Substrate must be dry, free from dust and grease. For filling the bottom of the joint, you can use closed-cell plastic.

Unscrew the cap from the extrusion tip, then cut open the cone. Screw the tip in place and cut to an appropriate size. Extrude sealant into the joint, then smooth immediately using a trowel or fingertip moistened with water. Once finished, leave the extrusion tip in place and close the cartridge properly. To facilitate cleaning, apply, for example, masking tape onto both sides of the joint. Remember to remove the tape right after application.

Always remove the old silicone from joints before applying new, and remove possible mould spots by using, for example, Kiilto Kodin Klorite according to instructions.
