Hi, what is the best way to level/square up an old wall frame? I have removed the lath and plaster from 2 walls and plan to replace it with Marmox backer board, however the existing timbers are not very flat across the width of the wall. I plan to screw cls to the sides of these but was wondering if this is the best method.
Cheers,
Stu.
