Great product and worth learning to use if it is new to you.
To repair badly damaged and poorly built walls in a cellar. It worked well despite that I didn't have several specialised tools needed with me, the crimper in particular is necessary to make the structural track and channel (or stud, as it is sometimes known in the UK) solid enough to work on.
I was delighted to find that Everbond's dry lining Pink Foam worked on it brilliantly.
