Existing ceramic tiles must be checked to ensure that they are firmly fixed with no signs of any loose or drummy tiles.
Can you tile on painted concrete.
You want water to readily absorb into it.
The surface should be cleaned and allowed to dry.
Unfortunately the tile cannot be adhered directly to the painted surface.
After you have a clean concrete slab you can grind down high spots and you can flatten or level the surface by using a patching mortar for tile.
As long as there are not structural cracks in the concrete floor you can install porcelain tile over it.
If the concrete has been sealed better adhesion may be achieved by going over the concrete with a grinder to create a rough surface.
This surface is called a scratch coat.
Tile cannot be attached directly to painted concrete as the thin set will not adhere well to the paint.
All paint will need to be removed before you begin installing the tile.

A scratch coat will give the mortar something to hold on to instead of the layer of paint over concrete.
Once the concrete floor is paint free the tiling process is similar to most other floor tiling jobs.
The surface must be free from dust dirt grease oil or other contaminating material.
If you use a stripper to remove the paint be sure to flush it thoroughly to remove any residuals.
Paint used on concrete will not bond with the tile adhesive.
