A cement mortar spray machine is a common piece of equipment in construction, whose core function is to spray mortar evenly on construction substrates such as walls and floors, directly replacing the traditional manual plastering work. During construction, you only need to put the mortar into the machine, which will spray it directly onto the construction surface after pressurized conveying. Compared with manual operation, it not only greatly improves construction efficiency but also produces a more even mortar coating, effectively reducing construction problems such as uneven thickness and hollowing.
This equipment also has a wide range of applications: it can meet the needs of indoor and outdoor wall spraying, cement mortar grouting, bridge grouting, waterproof and fireproof surface spraying, ceiling and wall coating spraying, as well as garden spraying, relief effect coating spraying,sound-absorbing material spraying, and so on. It is also suitable for waterproof plugging and repairing work. It is light and easy to operate for construction on various sites such as bridges, dams, hillsides, basements, tunnels, factories, and buildings.

Advantage Of Cement Spraying Machine
- The cement mortar spray machine features a well-thought-out design with an integrated pump and compressor for effortless mobility.
- The screw-type variant ensures continuous feeding without any pulse issues, boasting wide practicality for spraying ordinary mortar.
- It delivers uniform spraying with strong adhesion and comes with a full range of functions that enable both mortar spraying and grouting operations.
- The spray gun and spray pipe can be connected in any optional direction, allowing for easy and convenient operation.
Components Of Plaster Spraying Machine
- Power System: You can choose an electric motor or a diesel engine—both work stably for different job sites.
- Screw Pump System: Its core components (rotor and stator) are made of wear-resistant materials, ensuring steady mortar output.
- Agitator and Hopper Unit: The big hopper has an anti-clog grille, making sure the mortar is well-mixed before going into the pump.
- Spray Gun and Air System: The precision nozzles let you control how thick the spray is and keep it even by adjusting air pressure.
Working Principle Of Cement Mortar Spraying Machine
The cement mortar spray machine operates on a continuous automated process: uniform feeding→high-pressure compression→stable conveying→atomized spraying, fully motor-powered without manual pressurization, and operable by 1-2 people. First, pour mortar into the hopper, set spraying parameters, and close the anti-spill baffle. Start the motor to drive the screw rod for pulse-free feeding to the pressurization system. The high-pressure plunger pump compresses mortar to 8-16 MPa, with pressure/flow adjustable via the regulator for optimal effect. The high-pressure mortar is stably delivered to the spray gun through a wear-resistant pipe, then atomized into a uniform mist for even adhesion to the base—adjust the rotatable gun’s angle and speed for full coverage. After construction, rinse the pipelines and the gun with clean water to remove residual mortar and prevent blockage.
Feature Of Cement Mortar Sprayer
The cement mortar spray machine is easy to operate and outstanding in performance, combining high efficiency and economy. It can flexibly adjust the flow rate to achieve the best spraying effect. In addition to the switch on the electric control box, it is also equipped with a remote control switch for more convenient operation; the connection between the spray gun and the feeding pipe can be rotated to adapt to various construction angles, greatly improving operational convenience. The cement mortar spray machine is small in size, easy to carry on site, with low accessory costs and simple maintenance. It features high construction efficiency and good quality, being easy to use and fast, which can effectively save materials, labor, and costs. Only 3 people are needed to operate one machine, which can complete 150 square meters(2cm thick)per hour, with the material ratio of 0.7:3(cement to mortar), suitable for conventional construction needs.
Applicable Coating Materials For The Equipment
The cement mortar spray machine boasts excellent adaptability to a wide range of spraying materials, being fully compatible with various water-soluble materials commonly used in construction and meeting material needs across plastering, decoration, functional protection, and other construction processes, truly achieving multi-purpose with one machine. It can stably convey and atomize spray materials, including putty powder, latex paint, real stone paint, and other decorative coatings, cement mortar, dry mortar, thermal insulation mortar, and other basic plastering mortars, as well as waterproof, fireproof, thermal insulation, and sound-absorbing functional building materials. Simple parameter adjustments based on material properties are enough to meet different spraying requirements, with no frequent debugging needed. This greatly improves equipment utilization, satisfies diverse material spraying demands in construction, and effectively saves the investment cost of construction equipment.
