Description
Mortar sprayers are specialized plastering workers at construction sites who spray mortar onto walls and ceilings using dedicated spraying machines, performing base adjustments and waterproofing treatments. Before starting work, they clean the substrate and apply primer, and calculate and mix the mortar ratios. After spraying, they use trowels to ensure uniform thickness and surface smoothness. The work involves high-altitude operations, scaffolding, transporting heavy mortar, and requires teamwork. In recent years, the adoption of new technologies such as polymer cement mortar and automated spraying robots is progressing.
Future Outlook
Demand for construction and renovation, as well as maintenance work, is stable, and job openings are steady due to the shortage of skilled workers. Ability to adapt to labor-saving technologies and new material applications is required.
