A colleague of mine has bought a (limestone) stone fire surround and hearth.
The hearth is black granite and fitted OK.
The fire surround consists of 4 parts. 2 legs 1 lintel and the mantel.
We have figured out how it fits together but need help on how it is actually fitted to the walls.
The legs are not solid stone but made from flat stone panels formed into a U shape (ie a hollow leg)
The legs do not have any mounting brackets or holes for brackets on them. Theroetically they need fixing in place at the bottom where it sits on the hearth and at the top to hold it to the wall.
(the lintel and mantel then site on top of the legs)
Can anyone advise on how to fix the top and bottom of the legs in position?
Do we need to join the lintel and mantel using any kind of special mortar?
