I'm a bit of an amateur do-it-yourselfer and thought I'd tackle my hearth with a quick retile today. Should have remembered that nothing is ever quick or done in one day..

Once I removed the first layer of tiles, there was a second layer underneath. "Alright, let's just clear them all out and start fresh!" Well under those is about 4in of sand and small rocks that I was not expecting.

Both layers of tiles were uneven and broken, so I'm guessing this sand is the culprit.

Does anyone have an idea on how to get a trusty solid layer to tile on top of? One forum mentioned using a layer of self leveling concrete. Would that work?

Any and all recommendations welcome! Thanks!

 
I'd go ahead and get all tiles and sand out of there so you can verify what the floor is underneath. Post some pics and I bet you will get a lot of ideas on repair.

It is not uncommon. But you need to know what is under there to determine a course of action
 
Thanks for the replies! I removed all of the sand and rock and there is a layer of concrete underneath. It's very uneven but looks like it's in good shape.

I'm thinking of pouring light weight cement over it to get an even layer and build it up to the hight I want. Do you think that's a good approach or have any other suggestions?
Thank you!

What is under the concrete?
