is there such a thing as mechanical fastenings for large/heavy stone tiles - Tile Advice

[Julian 'Farmer' Bonsall]

Thanks for the feedback.

What did you tell them the temperature range is?

I have a wall the opposite side to an Aga and its chimney (paraffin burner) to do in the near future. The wall gets warm but I logged the temperature (you could use something like Mini Digital LCD Thermometer Temperature Hygrometer Probe Indoor Room Office CE | eBay - https://www.ebay.co.uk/itm/Mini-Digital-LCD-Thermometer-Temperature-Hygrometer-Probe-Indoor-Room-Office-CE/152628487236?epid=15005621374&hash=item23895de444:g:QZcAAOSw2kZZbbNA&autorefresh=true). The maximum I saw was around 64DegC.

Anyway my project is different but the attached document may be helpful. It states a temperature upper limit of 90Deg C like most of the Mapei products [Maybe most tile cements have this property I have investigated] The Keraflex Maxi S1 states the highest bond strength after heat ageing but not for natural (its what I think I will use). The Keraflex may work. Anyway I don't know how hot your boards get or if you need a material to insulate the tiles from the heat of the chimney.

I have attached an Ardex document which I found useful for my project.

It’s not like you Paul to be so slow

I’ve done them over the years and never had any problems. I’ve used a bagged S1 adhesive like Weber low dust spf and added in some Weber ad250 additive and grouted with a flexible powder grout. Primed walls first with acrylic primer diluted then neat and never used mechanical fixings unless over 3 metres. Notch the wall aswell as small notch the back of tiles.

I'm struggling to find any enthusiasm at the moment to be honest. I need a pint of "Pull yourself together"..

Could you use a mini saw such as this works one (has bevel capability) or a grinder / dremel to make the incisions for the wall brackets?
