How To Grind Concrete Surfaces Surface Prep

The coarser grit is made up to three or four rounds for making the concrete ready for fine polishing. The finer grits will result in ultra smooth and polished concrete surfaces.To prevent the floors from attracting dust and becoming rough again, high quality concrete hardeners are applied to the surfaces. For grinding new concrete surfaces, we may wait about less than a month to let it dry completely and cure properly.

Data Sheet Tolerance for Concrete Surfaces

2018-12-13  concrete. Unformed Surface: A surface that does not require formwork to provide either shape or finish to the surface, e.g. the top surface of slabs or pavements. These surfaces generally have to meet two independent tolerance criteria: the ‘flatness’ of the surface and variation from the designed elevation (levelness).

2021-7-16  These discs can be attached to any type of portable tool and should be operated at from 3,000 to 4,000 rpm. Wet rubbing is accomplished on green concrete by a slow speed grinding wheel or disc, at the same time applying water. The water, plus the rubbing action, brings up a cement paste which results in a very smooth, plaster-like surface.
