tiling a fireplace

[helpmeplease123]

Hi, I have a fireplace that is tiled. I would like to re-tile it using tumbled marble or tumbled tile. I would like to leave the old tile in place, is that possible? Also, is there some kind of glue or pre-made mortar strips(not sure what it is called) that I can use to do this? Thank you for your input.

Hi 123, welcome to the forum. Got a first name we can use?
Most of the top end (most expensive) thinset mortars will bond to existing tile. What kind of tile is on there now? Tiling over a fireplace does give you a thickness problem at the edges though. You'll need some kind of trim, depending on what new tile you pick, to hide the exposed edge of the old tile.

Thanks THulse for your previous answer regarding tiling over an already tiled fireplace. The tile that is on there now is 12inch ceramic tile with a smooth finish. Is there such a thing as tile tape to use for this kind of job? Thank you for your help. Jack

Fire place are super easy to tile,just run a board across top opening of fireplace,set all your tile from the board up,when it is set ,remove board tile lower portion and youre ready to grout,I tiled over brick with just a good quality thinset,I am sure you can tile over tile ,just watch that you will be able to make it look finished and that there is no place where the thickness of the tile over tile will cause a problem,it does help to scuff up any real shiny porcelin or shiny areas so the thinset will stick better,Have a great day!
