Hello. The hallway in my flat still looks great after decorating 5 years ago but cracks have appeared where some walls meet at the 90 degree angle. The lady upstairs had a badly levelled washing machine which I think was the cause. When I did the decorating all of the walls where they meet were like this and I used filler so it’s the filler that’s cracked.
I’d like to fix this with as little disturbance as possible to the rest of the walls.
I can carefully cut it out with a Stanley knife, leaving a groove.
What do you suggest is the best product to fill it with, that won’t crack under potential slight vibration?
Once the grooves have been filled I will paint with emulsion.
Thanks!
