MUSTANG H 7-Step Polishing Pad – 4 in., #400 Grit, 3 mm Resin
MUSTANG H 7-Step Polishing Pad – 4 in., #400 Grit, 3 mm Resin
The MUSTANG H 7-Step Polishing Pad is a 4 in. resin diamond polishing pad in #400 grit, step 4 of a seven-step ladder for polishing engineered stone, granite and marble. Ocean Diamond builds the H series with a small-brick segment pattern that increases the flexibility of the pad; the resin layer is 1/8 in. (3 mm) thick and the pad is rated to a 4,000 RPM maximum. This grit is the midpoint of the ladder, where grinding gives way to the first stages of polishing.
Engineered stone is wet-only on this pad; Ocean Diamond allows dry or wet use on granite and marble. The full ladder runs #50, #100, #200, #400, #800, #1500 and #3000, each sold as its own listing, so the #400 pad follows the #200 pad and is followed by the #800 pad. It is not a porcelain or ultra-compact pad — for Dekton, porcelain and ultra-compact edges use the Diamax Cyclone Ultra Wet/Dry Pad – 4 in., for Dekton, Porcelain & Ultra-Compact.

Frequently Asked Questions
Where does #400 sit in the sequence?
It is step 4 of seven, a transition grit — the surface starts to close up but is still dull.
Can it be used dry?
On granite and marble, yes — Ocean Diamond allows dry or wet use. On engineered stone the pad is wet-only.
What is the maximum speed?
The H series is rated to a 4,000 RPM maximum.
How thick is the resin?
1/8 in. (3 mm).
Does it come as a set?
No. Each grit is sold as its own pad; buy the seven grits you need to build the ladder.
