Hi all.
I fancy using slate tiles for a hearth and back.
So it would be 4 x 30cm square tiles for a 1.2m length hearth
but how should I build up the height to the usual hearth depth?
n.b.
I will be surrounding the front and sides with timber to cover the
edges of laminate flooring.
I used a mortar bed.

Make sure you check minimum hight above existing floor and depth
required for any type of fire you might use there. ISTR gas fires
require 2" (or probably 50mm nowadays) above existing floor
coverings, and I can't recall the depth required.

How did you set shutter the mortar bed?
And what mix of mortar?
And..did you set the tiles on tile cement...

Look I've done it many ways.

Concrete blocks laid on the side bedded on about 3:1 mortar is good for
deep stuff. For less depth use straight mortar with sharp sand and a bit
of aggregate thrown in, and reinforce with wire. You ar probably not
advised to go less than about 50mm with concrete though..less than that
is practically a matter of simply hoping the substrate is not flexible,
and using just a thick mortar bed. And slapping slates straight on top.


Ive used thick tile cement for up to 1.5" depth. Proper stuff. None of
yer shed 'tubs'. Ardurit fast setting.
