Amount of water

Low grit pads, 50-100-200, can be used for dry polishing or with small amount of water. If you don’t feel the lower grit pad biting the material, chances are you are using too much water and probably too high RPM. Starting with grit 400 and higher, it is recommended to use more water. Using a suitable amount of water makes the pads work faster and increases their life.

Set the polishers RPM

Too high RPM will create excessive heat that will result in white resin pads smearing on the stone. In other cases, it will even burn the stone itself. As a rule, for 50-100-200-400 grit pads use 2000-2500 RPM and with 800-1500 grit pads use 3000-3500 RPM. If you want to compensate for the loss of RPM, you can always add an extra pass. Never use above 5000 RPM.

Use the whole pad

Here are two of the most common problems that emerge from using the middle portion of the pad:

1. When using abundant amount of water while applying pressure to the pad’s middle portion, water will get trapped between the pad and the stone, causing a hydroplaning effect. As a result, the pad won’t touch the material’s surface properly and certain spots will not be polished.

2. Users who use minimum amount of water will notice the pads flexing and cupping outward around the middle. This way, only the edges of the pad will touch the stone leaving dull spots in the middle. Applying more pressure can fix this issue, but due to the flexible nature of the pad and the thickness of hook and loop used to secure it on the backer, these blurry spots might remain. To overcome this issue, use the pad’s edges as you alternate from the top ½ to the bottom ½ while you slide across the stone edge. You should feel the pad’s contact that will allow you to release some of the pressure.

Use a rigid backer pad

Think about the automated profiling machines which all use rigid tools and backers and in the same time they generate way better results than most fabricators could achieve by hand. If the flexible backers were the key, be sure you’d see them used on all auto-edge machines. Although flexible backers work well for concave profile edges such as ogees, the truth is the need to use them on almost any other profile is rare, plus the job can be done with a rigid backer as well with patience.

Polishing Project

Lower Grits - remove scratches

Use the polisher initially at low speed (1500-2500 RPM) and then increase its speed slowly for faster polishing suitable for specific stone. Skip no grit and start polishing the material edge with side-to-side motion from the top half of the pad to the lower half of the pad. Do not move to the higher grits until you find a smooth surface that is free from all saw marks or old sealant.

Higher Grits - achieve shiny finish

With higher grits (400, 800, 1500), add more water and increase the RPM to 3000-3500 to avoid burning your stone’s surface. You will find good shine starting with grit 800, and the grit 1500 will bring a mirror like finish.

Choosing the right Pads for your project

We noticed during the time many customers who think all pads are the same and they are exactly the customers that have trouble during the polishing process. There are colored pads on the market that can reach good quality polish, but often they require more time and sometimes they even transfer the pads color onto the stone by the end of the process. Our recommendation is to use white resin pads.
