The types of protection generally present, are waxes and polymers (emulsion, pore filler or resin). A simple way to verify their presence is to wet the floor. If the water doesn’t form a continuous film on the floor it means a protection is present.
It is then advisable to scrub the floor with a solvent and to verify if foam appears.
Another way to verify is to lightly sand the floor with emery paper. You must then verify if dust is formed or if there are scratches as on a plastic support.
If a protection is present, it is advisable to start with stripping before starting the renovation of the stone.
