The Delta resin polishing pads are extremely universal. The lower grits 30, 50, 100 and 200 can be run wet or dry with great honing results. They are nearly incapable of leaving inconsistent scratch patterns, and therefore, very safe to use on many different concrete types. When using these lower grits on overlays, run the machine approximately 25% faster than on concrete, dry only, and with the weights off.
Grits 400, 800, 1500 and 3000 should always be run dry on all surfaces. This will produce an impressive shine on a broad range of floor conditions with true and lasting results.
These pads perform like many other competing premium pads, yet they are priced as one of the most economical resin pad options available.
