Hello,
I want to install natural stone window sills myself inside our house.
At the building materials store, they recommended hydraulic lime mortar for the installation.
... So far, so good ...
What should I pay attention to during the installation?
Is the mortar applied with a notched trowel (like for tiles)?
Or, based on my intuition, should I lay the stone slabs into a "mortar bed" and then level them with a spirit level?
Do I need to treat the slabs or the substrate beforehand, such as with a primer?
The window sills will be attached to sand-lime bricks and the plaster on top of them.
