How to choose the right Diamond Polishing Pads for different stone, granite, marble, engineered ston
Which Color Do You Need?
All Diamond polishing pads working surface come in different colors and the colors are based on the aggressiveness of its ability or "scrubbing" capabilities.
Typically, lighter colored pads are thinner. Polishing pads which are beige, white or off-white are used for less-aggressive tasks such as light cleaning or burnishing on engineered stone, marble, quartz. Buffing work is always at a high speed of the wet polisher, so light colored polishing pads are used to prevent staining, polluting or penetrating the countertops or floors with a darker polishing pad. We call the light color polishing pads Engineered Stone polishing pads, Marble polishing pads. We develop different formula for polishing different color stone with combination of stone hardness and texture.
For aggressive polishing work, the darker polishing pads are thicker and used at a slower speed with Variable speed wet polisher to prevent scratching the stone countertops or stone floor. Green or blue pads are typically used at a slow speed for basic sanding and red or pink polishing pads are also used at slow speeds for buffing. Please note that red polishing pads should never be used at a high speed because it will leave splashes of red dye on stone countertops or stone floor.
When polishing a stone countertop, use air wet polisher/pneumatic wet polisher or electric wet polisher with variable speed from 500-4500 RPM. You must use a adjustable speed wet polisher for different grits of diamond polishing pads or for different area of the countertops. For flat surface, you can use 4500RPM. For curved area on sinks, you must adjust the wet polisher to lower speed. It depends on operators experience.
Which Speed Do You Operate?
For coarse grit #50, you can use full speed. For #100, #200,#400, you can operate from 4000 to 3000RPM.
When restoration a floor, the speed must be very slow (about 175 RPM) and coarse pads are used. The powders of coarser polishing pads cut through the surface easier which makes it easier to grind off layers of wax, polish and other buildup from the floor. The coarsest pads are darkest in color, usually black or something close.
Diamond Polishing Pads Grits
While using diamond polishing pads, you will also have to choose the grit number which is proper for the work on hand. Grits on polishing pads are similar to the grits on sandpaper and range from 50 to 3000 grit.
The lower the grit number, the coarser a diamond polishing pad is. If you are going to remove scratches and small chips, you would typically be recommend to start with a 50 grit pad which is course enough to even the surface out. Once you have removed the scratches, you will move up to about a 200 grit to dull the surface and remove the buildup of wax and dirt. The final polishing step is to use a #3000 polishing pad to get a shine and gloss. So if you want an extra glossy, mirror-like finish, you would have to use the highest grit available such as Buff.
