How to prepare a concrete surface for the installation of a bulk floor First you need to prepare a concrete floor, clean it of dirt and dust. This is done using a powerful vacuum cleaner. Then be sure to grind the floor to improve the viscosity of the plate. This is very important before laying ceramic tiles. The tile does not allow the floor uneven.
