I will hopefully get 50 sqm of Indian sandstone down before the bad weather starts (did it ever end?) on a full mortar bed. I understand that there has to be a fair depth of gap for the Romex so I will remove the mortar from between the flags while it's still wet. What would be the best depth?
If I don't get the patio finished and pointed before the winter, will I be okay to leave the Romex until next spring?
Does anyone know of any stockists in the north of Scotland?
