What is margin of error for floor level?
We are installing 12x12 marble tiles on a concrete slab. After pouring self-leveling underlayment, there are still some very slight dips and rises. When we laid the tiles out in a dry run, there is some tipping to some of them. How much of this is acceptable, absorbed by the thickness of the mastik?

Hi
It's almost impossible to say without seeing the floor...but for marble... (which is not easy to lay if you are a beginner)..the floor should be as flat as possible. You will get some relief from the thin set you use(and it is thin set...do not use mastic)...but you'll get a better idea once you get started.

First off I would reccomend using thinset instead of mastic. As you have discovered a flat floor is very importaint with larger tiles. If your floor is not perfectly flat I would reccomend using a larger trowel, something like 3/8". and a 6' level to keep all the tiles on the same plane.
