Thanks all
The limestone for the hall is from Manderine Stone and it is Marfil Honed 600 x 400 x 20,
Tough stuff m8 shouldnt need sealing b4 you start go gentle with it is very hard so chips and can break along the veins. White flexible adhesive would be favourite I would think
The limestone for the bathrooms is once again the same Marfil but polished and 610 x 305 x 10.
Mandarin are known to mesh their 10mm mafil so will take a little longer to go off once on the wall. Same adhesive as floor and again I would seal after. Check if its beveled as might look better with a 3mm spacer.
Oh yes, the hallway is concrete and the two bathrooms are floorboards so I guess I have to ply line them and then hardibacker?
UFH ?? if not straight onto concrete providing its well cured and in a good state of repair. Overboard with 10mm poly no advantage to using hbacker once over ply'd will need a uncoupling membrane tho over the ply.
The honed stuff says it is suitable for high traffic. Anyone used this before?
Easy one of the best to be having a start with.
Many thanks for all the useful advice.
