You need to prepare by removing the paint and scarifying the surface to open up the pores of the concrete. Before you lay any sort of tile whether it is stone ceramic or peel and stick vinyl you must prepare your concrete floor to ensure that the tiles will go down properly and stay where they re. The tile installer is right. All paint will need to be removed before you begin installing the tile.
If you use a stripper to remove the paint be sure to flush it thoroughly to remove any residuals. As long as the paint is down well and not flaking you can go over it with some preparation. Sheets of cement backing available from most do it yourself. Once the concrete floor is paint free the tiling process is similar to most other floor tiling jobs.
