Ledgestone veneer 1 1/2 to 2 inch stone was added around a gas fireplace. This installed directly on hardy backer board with Licote proline Premium adhesive. My question is there ANY chance that the heat from the gas fireplace with break down the adhesive over time and stones will fall off the wall? thank you
According to this document it can sustain 250 degree F with occasional exposure. It will be difficult to determine just how hot it gets at the glue layer, since the stone and backer board act as a heat sink, and what is on the surface of the stone, will not be the same at the glue layer.
