Extreme high quality 4" dry polishing pads with hook and loop backing. Will attach to 4" Velcro backer pad. Can be used on a stone polisher or variable speed grinder. Ideal for jobs where a wet polish is not possible. By using a dust collection shroud on your grinder, almost all of the mess associated with polishing can be eliminated.

RPM: 2000 - 5000 (around 4000 recommended).

These pads are meant to polish smooth troweled concrete. If concrete is very gritty, you should consider wet polishing pads or start out with a diamond cup wheel before using the dry polishing pads.

For a deep grind to expose larger aggregate, wet polishing pads are also recommended.
