FUGI forming tool. Produces step-by step profiles without masking tape or cleaning afterwards. 
The kit includes...
1 Tool - 12 different ways of use:
1 x 180°C angle
1 x 90°C angle
4 x 45°C angle (16, 10, 8, 5mm)
3 x concave grooves (20, 14, 10mm)
3 x convex shapes (r = 10mm)
Removal Knife, 1 jagged blade and 1 stanley style blade

This multifunctional tool can be used for many flexible sealants and caulks.

A releasing agent (soapy water) is not needed to apply the soft caulking mass (silicone). 
This process results in better adhesion and prevents mould from forming underneath. In the event that the profile application is not perfect, it is possible to remake isolated parts without having to remove the entire profile.
