1 Alte Dübel, that are no longer needed after the renovation, must be removed first. This works best with a thick one, self-tapping wood screw and strong pliers, So-called grip pliers are ideal. Always turn the screw in by hand as far as possible.
2 Mit einem normalen Staubsauger und aufgesetzter Fugendüse wird loses Wandmaterial aus dem Bohrloch restlos herausgesaugt.
3 Zum Füllen der Bohrlöcher ist gebrauchsfertige Spachtelmasse aus der Tube ideal. Insert the grommet as far as possible into the drill hole. When squeezing out the filler, slowly pull the spout out of the drill hole and fill the hole from the bottom up.
4 Danach soll die Spachtelmasse leicht über die Wandoberfläche hinausstehen. It is immediately smoothed off with a spatula. This should be two, happened three times in different directions.
