Hi
i used it a couple of weeks ago to make good some imperfections in a small bathroom, I was very happy with the result, first time using it but a bit of elbow grease required to sand down some areas that I had not properly skimmed over.
If you have had plaster removed then you will need to use a standard filler like polyfilla to bring it almost up to surroundid area as ready to roll is def not a filler.
I will be using it ongoing as a little goes a long way if you are redecorating its brillant for taking out small imperfections.
Good luck with the work
