Help Leveling Two Different Slabs in Preparation for Tile

[jacobm99]

Hi, Guys.
I recently bought a house where the previous owner extended aprx 40 feet on to what was originally a standard 2 car garage (now measuring 20'x66'). The previous owner tried to transition the two slabs, but it doesn't look so great and there is approximately 3/4" to 1" difference in height. I would like to level the two so that I can install some porcelain tile, and was hoping to get some recommendations from the experts here as to how to go about doing that. Pix below.

You can either skim coat the lower slab with thin-set and a trowel to build it up or use dry pack. Doing dry pack without some background experience will not be easy.

Mud Job. Click my renovation link in my sig. My floor was way the hell more messed up. All good now.

Im not sure if you want both slabs level or just want to feather the edges. Contact your local provider to find the correct material. We use Tamms thin patch a lot. It can be troweled on from a feather edge to 1" thick if I'm not mistaken.

What ever you do clean the floor really well and I would look into a bonding agent to brush on the slab before the patch

You should use a product that will hold up well. The cheap shelf bought stuff doesn't really create a long term bond. Vinyl or acrylic based products just don't cut it. At least do a really good prep. Grind and then acid etch and don't forget to neutralize and wash.

A bag of Thin Finish and a trowel would make the floor look new again.
