How to build up slab for tiling

Post by blaubner » Sun Dec 22, 2019 7:09 pm

I've removed the tile floor that was installed in my home during the 60s. My house sits on a concrete slab. The sub floor must be raised everywhere in my house, because when I began to demolish my half bath I discussed that the tile had about 2 inches of mortar underneath it. The finished floor was 2.25 inches off the slab.

Any suggestions on how to prepare a sub floor for new tile? I don't want to mix and fill a mortar bed like the original build if possible. Do I install a sleeper floor with OSB board? Am I setting my tiles up for failure by doing that?

In all honesty, a mud bed will be the fastest and cheapest method of filling the void. Look up "deck mud", you'll find both premix products and recipes for making your own. It is simple, fast, and easy to do.

Deck mud is the consistency of damp sand, so it's easy to place, pack, and trowel to height. While you're probably not using a Schluter Kerdi membrane, they have some great videos on how to lay deck mud. Shannon may have one as well.

I don't have any videos for that , it is not a common thing to see here.
