Pump That Sprays Hardcoat Stucco

This pump can spray most Sto products, including Powerwall® Stucco, and operates off of single-phase 230V power. It has a flow rate of 21 liters/minute, and can spray up to 210'. Sto Corp. has optimized its Powerwall Stucco to work with the Sto F-21 pump, resulting in a pumpable stucco mixture that sprays on better than any stucco on the market.

Randy Dorn and Randall Scott of Applewood Drywall’s Exterior and Plaster Division, near Milwaukee, Wis., are already seeing positive results. They stated: “To watch the F-21 Pump is unbelievable! The F-21 … has enabled us to do more work in a shorter period of time than ever before.”
