The invention discloses a Pandora stone floor. Firstly, an ultra-flat base layer is laid on the ground flatly, after the ultra-flat base layer is coated with a layer of binder, a millstone layer is laid on the ultra-flat base layer, then a layer of inorganic bonding material is cast on the millstone layer, coarse grinding, roll coating with a brightening agent and fine grinding are performed after curing, and the floor is prepared. The ultra-flat base layer and the millstone layer which are used for preparing the floor can be prepared in a factory in advance and then directly laid and mounted on site, so that the construction time can be significantly shortened, and the prepared millstone floor is flat, seamless, wear-resistant and pressure-resistant, has excellent mechanical strength and mechanical properties, has characteristics of diversified grains, environment friendliness, capability of saving energy, convenience in cleaning and the like and has brighter market prospect.
