Hello all,

we have opened up our fireplace, and are getting one of these fitted:

The fireplace is currently bare brick back and sides, , and a cement/floorboard floor.

As the bricks are not in the best condition, and plasterers have told us the cost of heatproof plaster is excessive, we are planning to get a local fabricators to make us a 1.5 or 3mm thick steel liner (finished in black) if that makes sense, which will sit inside the fireplace and cover the back and sides.

We have bought some exterior slate effect, but what I believe are sandstone tiles from Jewsons

And we have bought some BAL grey heat resistant grout to grout them in.

What we are unsure about is whether to use a simple sand/cement mix to pay them, or whether we need a specific adhesive that is flexible, and will reduce the risk of cracking.

What would people suggest?

Additionally is there a good spacing for the grout, I see some people said not to use any at all, and others said they kept it to a minimum, but I couldn't really understand why.

I have no idea how much heat will reach the actual hearth, as obviously it is on legs.

Anyone have any suggestions?

Cheers

Dan

Hi Dan,

The temperature at the base will be less than 100c assuming that your stove is compitable with 12mm hearths.

I'm planning the same as you. But I'm, well, confused! Look at these links.

Tell us how you get on.
Thanks for those links, I see where the confusion stems from!

We are having a go this weekend, chap who fits them is adamant sand/cement is fine, and i'm inclined to trust him with 25 years experience.
