Ceramic on fireplace hearth
I am considering the installation of wall grade ceramic tile on a smooth concrete fireplace hearth.
What types of heat resistant adhesives do the professionals use for fireplace applications?
I have both horizontal and vertical surfaces to cover.
I was told to consider the heavy duty adhesives in the tube for added strength but is that really the best approach?
many thanks

Adhesive in tubes and buckets are mostly junk and thinset mortar should be used in this application.

I am with Daniel. The tube stuff can turn brittle if exposed to heat around the fireplace thus loosing its grip and on a horizontal surface it will leave air pocket voids under the tile due to the ribbon application method which could cause a tile to crack under an extreme point load condition. A modified thinset is absolutely the way to go.
