Prep/Master 3038LP Propane

Propane - for Projects up to 10,000 SF/ 929m2

Prep/Master® 3038LP (Propane Model)

Ideal for Polishing Projects up to 10,000 SF/ 929 M2

The STI-3038LP Propane machine has the same robust design as the model STI-3030, but is powered by a 38HP Kawasaki propane motor. Despite its weight and size, this grinder is extremely easy to operate due to the smooth operation of the STI rotary gear system.

It features a movable pocket weight system for multiple applications and is recommended for projects up to 10,000 SF (929 m2). Its variable speed drive easily adapts to different grinding or polishing conditions for concrete, terrazzo, marble, and stone applications. Uses four tool plates (included).
