How should the lath be applied?
The lath should be applied horizontally; Surface should be rough as you rub your hand upward. This will make the lath angle down against the wall forming little cups that will help in catching the mortar for the scratch coat. There should be NO bubbles or bounce in the lath – Don’t try to nail down bumps or bubbles once you have started putting up stone! (If there are any, and you have started putting up stone, they can be fixed with screws and fender washers).
