Sintered Pressed Metal Bond diamond tools are considered the industry standard for the initial wet cuts during the surface preparation and "canvas setting" stages of the polishing process.  These tools are designed with long life and work extremely well with all makes and models of power trowels and walk behind concrete polishing machines.  We recommend using these tools wet ONLY and never dry.  Best results when used with Sika™ branded refining agent wet.
