### ⭐⭐⭐⭐⭐ Regentonne jetzt dicht ...
*by M***O on 15 July 2019*

Meine Regentonne war an ihrem Bodeneinlass leider trotz festen Anziehens der Kontermutter und auch mit Dichtring nicht ganz dicht zu bekommen. Daher habe ich mir dieses Produkt gekauft. Was soll ich sagen: ich bin total begeistert. Es ist von der Konsistenz wie Knet und bleibt auch elastisch, härtet also nicht aus. Ich habe eine kleine Wurst (,- 6-7cm lang und 1 cm Durchmesser) um den Einlauf gelegt und ordentlich anmoderiert, das ganze von außen und auch von innen: Wasser in die Tonne gelassen und es war alles dicht. Auch jetzt (Monate später) hält alles dicht! Absolut empfehlenswert für Abdichtarbeiten.
