self levelling compound to raise hearth

mjl117 · 27 Oct 2021

Hi

I've opened up an old fireplace and want to tile the hearth and the inside (floor) bit. I want the tiles to sit approx. with the finished carpet level (the carpet is not fitted yet)

Can I use self-levelling compound to 'raise' the hearth by say 10mm or would it not be strong enough?

I don't really want to remove the current hearth (which sits level with the wooden floor) as it is in a fair (and flat) condition

Thanks

Hi,

I'm only a DIY'er, so feel free to ignore!

But it sounds to me like you could just lay a sheet of cement board (cut to fit!) on top of the original hearth and that would be good enough to tile over?

Though, are you going to have a fire in the hearth?
There is a good reason for having the hearth and carpet at different heights!

Yes you can no problem. Made sure it’s a moisture tolerant smoothing compound ( latex, bag & bottle ) like Laybond ultimate , ardex NA , Mapei trade plan , f ball 1200 pro

Thanks, I should add that the fireplace won't be used. It will just be decorative! So the "fireplace" is now just an opening with new lintel fitted and boarded up inside. I just want to have the hearth and interior floor of the opening tiled

Good idea about the cement board, I'll take a look, although I will still need to level the inside of the fireplace (I'm sure that bit has a name) as it is currently quite bumpy. I'm not sure what it consists of but it is rock hard and has stones in it, the house was built around 1900 if that's useful.

I believe it's called the....
...'inner hearth'!

Thanks, why does it need to be moisture tolerant? (genuine question!) It is for a fireplace on the first floor, cheers

Slightly old picture but just to give some context, the sides and back has been boarded/skimmed now and the hole at the back fill with cement

Didn’t think to ask that. Should be ok with any then as you won’t have any moisture to worry about.
