new hearth too low

[rodstrottertrading]

We've bought a new hearth, as the old one was cracked when we moved in. The only problem is, it's a slightly thinner than the old one. There is now a approx. 1/2 inch gap between hearth and the fireplace (which appears concreted in place).

Any suggestions on how I could raise the hearth to close the gap?

Thanks

What's the hearth set on to....is it concrete?
If so, either lay a thin cement screed or dot and dab until you get the correct height.

Yes exactly - concrete. I've only ever dry-laid concrete for a patio, and a few times wet mix for filling big gaps. So basically, build it up to the right level, use the spirit level, let it dry and then put the hearth back on top?

Thanks

You can certainly do it that way, or you could put some wet cement pads down, drop the hearth on them and gently tap down until all is level, pointing up the edges when you are happy with it.

Great, thanks John. Can I just put the wet cement straight down onto the concrete floor, i.e. I don't need a wooden frame or anything?

We got some new laminate flooring put down around the new hearth. I'm guessing the height (created by the underlay+laminate) will help keep the concrete in place as it dries.

You aren't pouring wet concrete into shuttering - you are using a stiff'ish cement/mortar mix to bed the hearth onto - very similar to laying a slab based garden path using 'dot and dab'.

The mix needs to be stiff enough to stay where it is put and to support the weight of the hearth.
