FIELD GUIDE TO CONCRETE REPAIR APPLICATION PROCEDURES
Spall Repair by Low-Pressure Spraying
Low-velocity, low-pressure sprayed mortar used for spall repair comes in the form of prepackaged mortar. The spray is applied using small concrete pumps or heavy-duty grout pumps to force the low-slump mortar through a hose. Air is added at the nozzle to impel the mortar. Bond with the prepared substrate is achieved through a combination of proper surface preparation, low-velocity impact, and the material properties of the prepackaged mortar.
