Tiling fireplace (calcium silicate boards)

[Torbjärn]

Hello,

Is it possible to tile regular tiles on my fireplace which is currently only built with calcium silicate boards? The idea was initially to plaster it, but now I'm considering that glazed tile.



Does anyone know how to go about it?

Best regards,

Torbjärn

Do I need any special material that withstands heat well?

You need a polymer-based fix, e.g., Kiilto Highflex S2 DF, which can accommodate thermal expansion.

Thanks! What about the grout, anything special there?

Should one use mesh behind the tiles or is it enough to prime the boards?

I used regular grout and it has worked without cracks for 2 years. I think you should be careful to get a good fix with the adhesive. I applied it on the substrate and also on the tiles. It holds.

Thanks. When you light a fire in your stove, do the tiles get warm then?

Thanks. When you burn in your stove, do the tiles get hot?

Yes, so hot that you can't touch them.

Ok I'll give it a try

Had forgotten about this thread, but here's the final result:


When I light the fire, the plates at most become lukewarm, not warm
