Wet stone polishing machines are used for polishing granite and other stone surfaces with wet diamond polishing pads. They have a water feed attachment that directs a steady stream of water onto the wet pads and stone surfaces. A wet polishing machine is a powerful piece of equipment that allows the user to get the job done efficiently and effectively. A high-quality wet polisher is durable and powerful and can produce a beautiful finish while evenly distributing the water and providing optimal torque control.

Benefits of buying handheld wet polishers

Wet polishing dates back to the 1900s and is the oldest form of surface preparation for concrete. Although opinions differ as to whether wet or dry polishing is better, there is no doubt that there are several benefits of buying handheld wet polishers. This type of handheld wet stone polisher offers several advantages:

1. One of the main advantages of buying/owning a handheld wet polisher is the fact that wet polishing is the oldest method of polishing. With over a hundred years of knowledge and expert opinions, it is the obvious choice for those with extensive experience as well as beginners.
2. By using a hand-held wet polisher, the surface is not abraded.
3. The water used in wet polishers acts like a lubricant. It reduces friction and cools the diamond tools during the polishing process and helps in cleaning the abrasives.
4. As in any other industry, companies and workers must comply with OSHA ( Occupational Safety and Health Administration) regulations. Using a handheld wet polisher means that work is completely dust-free and this process eliminates problems that could arise or be a cause for concern due to OSHA regulations, such as hazardous dust. However, companies and employees must still wear personal protective equipment (PPE) when using a handheld wet polisher in order to avoid harmful exposure.
5. Using a handheld wet polisher can increase the longevity of the tools. Molten resin is eliminated because polishing is done at a lower temperature, which ultimately increases tool life.
6. Dry polishing increases pitting on the floor while using a handheld wet polisher decreases pitting.
