STI Grout Pans

The rotary action of the Prep/Master® pushes the epoxy into the holes from multiple directions to push air out and epoxy in! The mechanical action is much faster and more effective than the traditional method of hand troweling with the calcium carbonate powder. Fills up to 95% of the pinholes! Fills the pin holes in terrazzo more thoroughly than the conventional way of hand troweling and buffing the epoxy into the holes. Works great on concrete floors too. Run pans at very low speeds to save lifetime of the pans and prevent burn marks in floor: 15Hz (electric) or 2100 RPM (propane). Use only on the Prep/Master® or any other rotary machine. Velcro-backed for easy tool change. Lasts over 10,000 SF (929 M2) if following instructions above.
