Yes for grout, mortar, stucco any material contenting sand. Lower compressible materials calls for the hose to be primed. To prime the hose fill the mixing chamber with water and add 2 shovels of portland cement into the chamber. Add material to the hooper, switch on the feeding wheel and start the pump pushing the cement slurry followed by the material or pour mixed up cement directly into the hose before attaching to the pump. Failure to prime the hose can result in clog in the hose. Slurry priming not needed with fireproofing self leveling underlayment, acrylics and epoxies.
