An abrasive machine is utilised in addition to the graded diamond pad which essentially smooths the concrete down. Concrete grinding is performed either wet or dry.
The advantages of wet grinding is a reduction in dust and removes the requirement for vacuums. However, cleaning of the resulting Slurry is required. Concrete must be dried before the application of any coating or overlay, which can take several days.
Advantages of grinding dry include ease of cleaning and the floor is ready for sealer application immediately. However, appropriate respirators and vacuums must be used when grinding concrete dry to ensure the safety for workers.
