Wow, I can't believe it's been five years since I posted here:

The sunroom floor tile turned out well five years ago and still looks great. Thanks for your expert advice.

I'm thinking about a new tile project: tile over the nasty, 1960-era brick facia on the hearth and front of our fireplace:

We plan to do this before installing a new woodstove insert.

I need advice on how to install tile over the brick fascia. My wife and I were shopping for woodstove inserts and noticed nice tiled walls/hearths on a display wall at the woodstove store. The owner said the tile was from Home Creepo and relatively inexpensive:

So, can I just lay tile on thinset over the brick, or should I install concrete backer-board first?

What do I do with the corners?

Will the heating and cooling of the front/hearth cause problems with the tile?

Thanks in advance.

You can install tile directly on the brick. First, clean off the soot. I'd give the entire surface a good wirebrushing to remove the soot, dust and any lose mortar or brick parts. The, you can skim coat the surface with thinset to fill the mortar lines and level the surface, or if the tile are fairly large, skip this step and start setting the tile. I'd do the sklim coat 'cause it's easier to tile a flat surface.

That's what I wanted to hear!

What about heating and cooling of the hearth and tile. Will the expansion and contraction cause problems?

I figure I'll need to wait a couple weeks after the tile is finished before firing up the woodstove insert, right?

Heating and cooling will be negligible. The bricks, brick mortar, thinset and tile have expansions rates that are fairly close to each other, and due to their good thermal conductivity, will be at nearly the same temperature.

Waiting a couple of weeks is good.
