Polishing looks simple but the results depend on the order and the tooling. Because countertops are vertical, curved and irregular, you use flexible diamond resin discs (frequently 3-inch) used wet, working from 50 through 3000 grit stage, with special attention to rounded edges and sink cutouts. To burnish a concrete countertop or sink, demold after proper curing, abrade through a wet diamond resin pad sequence by hand on a variable-speed hand grinder, then seal.

Freshly cast concrete requires at least 5-7 days of curing before aggressive abrading; burnishing too early pulls aggregate out.
This stage decides how much reflection the floor finally shows.
What matters most in this stage.
Use a variable-speed polisher at low rotations per minute (around 2000-3000) and keep the surface wet.
Countertop work is almost always wet burnishing: it controls fine dust, prevents the resin from loading, and produces the clarity concrete designers want.
Miss this step and the gloss will not come up evenly.
The practical details.
Once the piece is fully dry, apply an impregnating sealing layer and, for food-reach out to surfaces, a food-safe topical finish.
Crews that rush this part rarely get a mirror finish.
Key points for the polishing sequence.
Use a small 3-inch disc and keep it moving.
Concrete holds water in its pores, and a freshly wet-burnished piece can take several days to dry fully.
This stage decides how much reflection the floor finally shows.
A: In short, You can with dust extraction, but wet burnishing gives clearer outcomes and protects the resin pads from overheating on small parts.
A: The practical answer is, Wait at least 5-7 days of proper curing. Too early and aggregate pulls out; too late and the concrete is much harder to abrade.
A: For most jobs, They follow the same sequence, however flexible pads and hand work are needed so you do not flatten the profile.
