How hard is the processed ground? How do we distinguish?



Hard concrete or soft concrete can be basically understood by scratching the ground with an iron nail or a key. Those that cannot be scratched are classified as hard concrete (Fast Change Concrete Diamond Grinding Plate With Double Bars 40x12x12mm) .




1. It is recommended to use hard base metal grinding discs, durable resin grinding discs, increase the speed of the mill, and speed up the forward speed of soft concrete floors. Three Fan Shape Segments Diamond Floor Grinding Block For Large Areas Of Thin Coating Removal .



2. For hard concrete floors, it is recommended to use soft metal grinding discs, sharp resin grinding discs, increase the counterweight of the machine, reduce the speed of the mill, and reduce the forward speed (One Round Segment And 3x1/2 PCD Diamond Grinding Shoe For Concrete Surface) .




The quality of domestic concrete floors is mostly unsatisfactory, especially the refurbishment of old floors, the flatness is not good, the ground is loose, the hardness is very poor, the water mill treatment produces a large amount of mud, and the abrasive consumption is particularly severe.


It is recommended to use medium and large floor grinders. After spraying and drying in the shade, use dry grinding. First use 30# hard base metal grinding disc to remove loose surface layer and leveling treatment, and then use 100# medium hard base or soft base metal grinding disc for grinding treatment , After processing the flatness and basic hardness, the following is much simpler.
