Concrete Countertop Polishing Tips-Precast polishing

2019-01-18

Polishing pads come in a series of grits that are as follows: 50, 100, 200, 400, 800, 1500 and 3000.

Pads from 50 grit to 400 grit are actually grinding and removing material in preparation for the polishing stages. It’s better to start with wet pads to polish your countertop. When you are working hard with the pads, and there is no water to cool the pads’ resin, it turns soft and releases the diamonds. The 800 to 3000 grits will make your countertop surface smooth and beautiful. On some mixes, 1500 grit will be the last pad that you will use, although other mixes will still continue to polish at a 3,000 grit.

Generally speaking, a 50 grit would give you an exposed aggregate look. If you are just polishing the cream, you will start with a 400 grit. You will then work your way through the different grits until the desired look has been achieved.

If you’re looking for a super-high sheen, then running your 800-plus grit dry will pop a shine that many didn’t realize was achievable. At this point, the pads will not be removing any material, so you will see little to no dust at all. The hot pressed pads are by far the best dry pad for an ultra high shine.
