If you've got a gap behind where the tape is going you'd be better off filling it out first with something quick setting. Easifil maybe.Hi ,
Yes that is the roller . Have you ever used one ?
Yes I have a corner trowel which is OK and I can get a decent angle with that and a straight trowel but sometimes when there are gaps at the top of the wall board it's more difficult. For me the customer will inspect that corner and expect it to be perfect . Sometimes the following day I may have to tidy up the angle with some more filler which is a pain .
Thanks for the replies
