EG Grout Pans for Terrazzo & Concrete

EG Grout Pans fill the pinholes and small voids in epoxy terrazzo and concrete floors — working epoxy and marble flour (calcium carbonate) into the surface so your finished floor is smoother, denser, and free of visible holes. They’re the #3.5 grout step in STI’s TPS terrazzo system, and they mount on your Prep/Master® machine.

What They’re For

• Filling pinholes and voids in epoxy terrazzo during polishing
• Filling surface pinholes in concrete
• Creating a smoother, denser surface for a cleaner final finish
• The grout (#3.5) step between cutting and polishing in the TPS system

Key Details

• Patent-pending stainless steel grout pans
• Run with epoxy and marble flour (calcium carbonate powder)
• The #3.5 step of the TPS Diamond System
• Run slow — 15Hz (electric) / 2100 RPM (propane) only, with pocket weights on the handle; never above 250 RPM tool speed (running faster shortens pan life and can burn the floor)
• Approximately 10,000 SF life

How They Work

After the grinding steps and before polishing, the floor is grouted to fill pinholes. The grout pan spreads and packs epoxy and marble flour into the surface; after it cures (8+ hours), you polish — and the holes are filled for a tighter, more uniform finish.
