Hi there, I'm going to be building the dwarf wall on my porch out of the local soft limestone.
I know that when it comes to repointing this should be done with Lime mortar, and I will indeed be pointing my porch with it. But I was intending to lay the stone with a cement mortar as I assumed this would be stronger, leaving enough depth for pointing later with lime mortar. (inside will be renderned with waterproofed cement, slurry then render again.
Am I wrong in thinking this (bearing in mind the wall is only single skin 150mm so I I leave 25mm for pointing I lose 1 sixth of the contact for cement)
Should I just build it with Lime paste from the start? (Certainly more hassle)
Thanks for any tips,
Tom
