Can construction adhesive be used behind cultured stone on dura-rock near a woodstove? I was talking with a mason and he said that they sometimes used const. adhesive on the stones instead of buttering the back and sticking them to the scratch coat. Wouldn't the heat from a stove be bad for the adhesive? Off gasing, or potential fire hazzard? I know it is not as flamable when dry but I would think it would still be a no-no, not to mention I have not seen this by the mfg companies.
