Removing coatings with a concrete grinder
With a concrete grinder you can remove old floor coatings, level the concrete beneath and at the same time create a perfect surface for further preparations of your floor.
HTC concrete grinder for rough concrete grinding
Concrete can vary in properties a great deal. When you use a concrete grinder for hard concrete a segment with a softer bond than the standard type is required, to grind properly and avoid glazing. On the other hand, soft concrete requires a hard bond to avoid excessive wear of the tools. Therefore, always check the wear of the segments after a while, to see that no abnormal wear occurs. If so, try if another type of tool works better, with this specific type of floor and grinder.
Before starting the concrete grinding, check the floor for bolts or other metallic obstacles and remove them, as they can destroy your segments completely.
As a preparation for a carpet or thicker coating, a coarser single stage grinding is normally adequate and there we have a number of different suggestions covering all type of concrete. For thin coating or paint, a follow up with a finer segment is required. Alternative segments are available for different concrete properties there too.
Finally, if you find an extremely hard concrete, causing glazing also with the correct tooling, try to wet the floor somewhat since damp concrete is much easier to grind.
