The present disclosure provides an artificial floor. The artificial floor comprises a plate body with a pad portion on a surface thereof. The pad portion contacts with a subfloor when the plate body is disposed on the subfloor. The plate body could be various kinds of the simulated floor such as linen, wood, or stone. The simulated floor is poor in wear resistance. The vibration or shaking during transportation may cause wearing between the simulated floors so as to damage the surfaces of the simulated floors. The subfloor may have an uneven surface, which may affect the surface flatness of the plate body disposed on the subfloor. Therefore, the pad portion of the plate body could be used as a cushion for the transportation process to protect the collision and wearing between the plate bodies. The pad portion could also be deformed locally to close the surface of the subfloor.

This invention relates to a thin and texturized film that can be applied onto a non-smooth surface to improve hardness, corrosion resistance and wear resistance properties of the surface while maintaining the underlying profile of the non-smooth surface. An additive overlaying process can be employed to produce the thin and texturized film on the non-smooth surfaces without substantial alteration or degradation of the underlying surface texture or profile of the non-smooth surfaces so as to sufficiently preserve the underlying surface texture or profile. The thin and texturized film fully covers the non-smooth in a uniform manner and maintains the surface profile.
