Note that the Situp Grinder kit fitted to a 9 in (230mm) angle grinder runs too fast for diamond resin bond pads, and grits above 80 mesh will quickly heat up the segments if the concrete is medium to hard strength. If the concrete was hard you would normally need to use a slow speed grinder or grind it wet.
The polishing process After the grinding and transition stages, polishing can be done with conventional resin tools or with pads. John Heidmann, a regional sales specialist with Concrete Polishing Solutions, says his companys most popular tools for polishing are in the Sektor system, which is numbered steps 1 through 5 instead of by grit and is designed to work with any active planetary

Plus we may have a little dip in the garage floor where the garage door pad isnt snug on the concrete. You can see on this bubble level that the cement slopes towards the garage.
With grinding diameters of 5 inches or less, these tools can''t replace walkbehind surface preparation machines for profiling large areas of concrete. But they work easily in tight areas where the larger units can''t maneuver, such as in corners and close to walls.
Certain turbo cups are designed to be run dry or wet. There are also 30grit brazed metal and resinbased discs that grind less aggressively. Grinding produces vast amounts of cuttings. It is best done wet to eliminate the clouds of hazardous silica dust that are generated when concrete is ground dry.

Concrete Grinding removes the finished surface of concrete and can leave the slab more vulnerable to water penetration, and oftentimes it doesnt truly eliminate the trip hazard. It is important to note that once concrete grinding is used, there really is no other solution that can be applied to the problem.
from floor to floor) If the aggregate is deep it will not be worth grinding that deep. Running the grinder at a low RPM may increase grinding speed in the course steps (14 and 30 Grit) by allowing the diamonds to penetrate the floor without overheating. This is most effective on soft concrete or concrete less than a year old. Experiment with speed
Grinding machines meant for this purpose are equipped with disks imbued with diamond bits capable to grind down the concrete as per need to offer it the desired shine. These tools use finegrit polishing disks to offer a sleek and smooth look to the floor.
