Tiling A Fire Hearth - TilersForums.com

[Andy Allen]

I got 2 fire hearths to tile next week in 900 x 600 black limestone 20mm thick.
Fire off some sort will be sat on top after. Gas or wood burning.
Was going to use bal p t b adhesive do you think we this will be OK with the heat ?...think it's OK up to 200 degrees .

personally i don't like the way ptb mixes and trowels but it'll certainly do the job. i'd use any decent spf which allows a decent bed depth.
