SCP 400# SEMI-Metals

The last wet step in the SCP polishing sequence. The Semi-Metal 400# refines the slab surface after the Green Series tools and prepares it for final dry polishing with the Red Series — it's the transition point between cutting and finishing.

Yellow Series tools are dialed in for floors with a roughness average of 85 to 26. Contractors consistently report substantially longer tool life compared to 400# tooling from other manufacturers.
