Product details & application tips

The joint smoother is made of flexible plastic and is cut at an angle at the tip – depending on the desired joint width. After injecting the sealing compound, the joint smoother is placed directly on so that the edges lie tightly against the joint flanks. By pushing forward evenly, the compound is smoothed; excess material collects on the tool and can then be removed easily.

Tip: Wipe the tool regularly so that the joint stays evenly smooth. Prepare several cut-offs for different joint widths. Suitable for bathroom, kitchen, window construction and indoors and outdoors.
