I have just installed a kitchen in a summer house. However, the wall is not square in the corner where the kitchen counter is placed. When I have put everything together so that cabinets and countertops are straight and nice, there is quite a large gap to the wall in the corner.
I would need to "add" about 13 mm for it to be good with the tiles later.
How is this best done?
I am considering filling this in with the help of cut strips (1000 long and "fall" from 0-13), similar to plastering a wall. Which filler would you use in that case?
