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.
