Hi,
I notice in B&Q where they sell the plaster that they sell these metal mesh corners in a variety of different sizes. Am I right in thinking that you place these on, naturally, corners and then plaster over them to give crisp hard edges to walls?
If so, how do you fix them and I also see that they come in a variety of sizes - how do you judge what size you want? Are they a necessity?
Thanks,
J.
