This multifunctional tool can be used for many flexible sealants and caulks. The kit includes: 3 Tools - 16 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 (r = 5, 10, 15mm) 7 x convex shapes (30, 25, 20, 15, 10, 8, 6 x 3mm) Swallow-tail tool for tight corners and hard to reach areas All pastes, silicone, acrylic and polyurethane can be applied as a sealant, and flexible grouts are able to be formed paying attention to the Manufacturer's instructions. By holding the applicator so that it fits seamlessly to the wall and floor, slight pressure is applied so the flexible cutting edges fit well into the wall angle. Always use the absolutely smooth edge for spreading. Work step by step, by only doing short distances. Should the sealant go above the applicator, stop spreading, and clean it with a household paper towel. The applicator can be used on all smooth, rough or wave-like surfaces. When working on uneven surfaces push a little harder onto flexible edges. *Packaging may differ from that illustrated Returns Policy - Changed Your Mind?
