We're just in the process of fitting a new gas fire with new hearth. As we're adding a new hearth, the floor in the fireplace itself is now 50mm too low and needs to be raised so its flush with the hearth before the fire is fitted - what would be best way of doing this?
Si
paving slab, readymix postfix concrete, sand/cement mix... there's loads o ways of filling gaps.
Cut down paving slab.
P.
Fill it with cement?

Would a self levelling compound be any good?
Si
for 50mm ? no.
use a 4:1 sand cement mix, a fairly /dry/ mix. lob a bucket full in the hole, spread it out using a plastic float. leave it for half an hour and tool it flat. it's not going to be on show so as long as it's level it'll be fine.
No, that's much too deep: 5mm would be more like it for SLC. Just get yourself a bag of readimix from B&Q or Wickes.
