Limestone tiles advice

[rj1882]

good afternoon.

Went to look at a floor I’m doing. The tiles turned up and are 600x400 limestone tiles. I e got to self level the floor which is an old existing floor. Would you recommend matting the floor as well due to the make up of the tiled.

Thanks in advance.
