A GRC spray machine, also called a GFRC spray machine (glass fiber reinforced concrete spraying machine), GRC sprayer, GRC spraying machine, GRC shotcrete machine, or GRC glass fiber spraying machine, is a specialized device used to simultaneously spray cement mortar and alkali-resistant glass fibers onto molds or construction surfaces.
GRC (Glass Fiber Reinforced Concrete) is a composite material with cement as the matrix and alkali-resistant glass fibers as the reinforcing material. It is 70%-80% lighter than traditional concrete, yet maintains comparable structural strength and possesses excellent weather resistance, fire resistance, and plasticity—allowing for the creation of various complex curved surfaces, carvings, lines, and other shapes that are difficult to achieve with traditional materials. The core function of a GRC machine is to cut the glass fibers in real time and evenly mix them into the cement mortar during the spraying process. This “end-mixing” process ensures that the fibers are not prematurely sheared or broken, thus guaranteeing the structural strength and durability of the finished product. Without a spray machine, GRC can only be applied layer by layer manually, resulting in low efficiency, inconsistent quality, and high labor costs. GRC spray machines are also the most crucial production equipment in the GRC industry. If you are interested and would like to obtain more product information, please contact us now.

What Problems Can GRC Spraying Machines Solve for Users?
- Efficiency increase of 400%-600%. Manual spraying requires approximately 30-50 square meters per worker per hour, while a machine with two operators can achieve 200-400 square meters per hour. For the same output, the labor requirement is reduced from 4-6 people to 2, directly saving 60%-70% of labor costs.
- Material waste is reduced from 15-20% to below 5%. Manual spraying results in significant material waste due to mortar rebound and uneven fiber distribution. The machine’s closed conveyor system, combined with precise spray gun control, keeps material waste below 5%. Based on an annual production of 10,000 square meters of GRC exterior wall panels, this translates to thousands of dollars in savings on material costs alone each year.
- Product strength increased by 30%. The “end-mixing” process of the GRFC spray machine ensures that the fibers are mixed with the mortar only at the spray gun exit, avoiding the breakage and agglomeration caused by over-mixing of fibers in pre-mixed methods. The fiber distribution is more uniform, and the bending strength of the finished product is about 30% higher than that of the manual method.
- Reduced reliance on skilled workers. Manual GRC production relies heavily on the experience of master craftsmen—mortar mixing ratios, fiber usage, and spraying techniques all depend on feel. Machines are highly automated; once the basic parameters are set, ordinary workers can operate them after one day of training, significantly lowering the labor barrier.
- Expand the types of products that can be produced. With a spray painting machine, you can produce products that are difficult to achieve by hand: large-area curved curtain wall panels, intricate reliefs, thin-walled shell structures, etc. Expanding the product line directly brings new orders and profit margins.

How Much Does a GRC Spraying Machine Cost? How to Buy It Most Cost-Effectively?
Many buyers are most concerned about the price. Here is a clear reference range and influencing factors.
The market price of a standard GRC spray machine varies depending on the conveying capacity and configuration.
Key Factors Affecting Price:
- Conveying Capacity: The higher the hourly conveying capacity and the higher the pump pressure, the higher the price.
- Fiber System Configuration: Different single-fiber and dual-fiber feeding methods, and different cutting precisions, result in price differences.
- Pump Type: Screw pumps and piston pumps have different prices; higher wear resistance levels result in higher prices.
- Customization Needs: Customization features such as special materials, explosion-proof configurations, and remote control will increase the corresponding costs.
In addition to standard GRC spraying machines, YG also provides mortar spraying equipment of various specifications, which can be matched with mortar mixers, feeders, and other auxiliary equipment. Complete sets can be purchased, providing a one-stop solution for greater convenience.

6 Frequently Asked Questions About YG’s GRC Machines
A1: GRC stands for Glass Fiber Reinforced Cement, while GRFC is another name for the same material. YG equipment is compatible with both processes.
A2: It is not recommended to manually feed the sprayer with only one mixer. During continuous production, mortar is consumed quickly, and manual mixing cannot keep up with the spraying speed, leading to intermittent shutdowns. A high-speed mixer can be used to prepare materials in batches in advance, maintaining the continuity of spraying. YG’s five power combination schemes are designed for this purpose.
A3: Yes. GRC spraying requires a working air pressure of 0.6-0.8 MPa to atomize the mortar and propel the fibers. The air compressor is usually not included in the price of the sprayer and needs to be purchased separately or purchased from YG as a set.
A4: Operating a GRC sprayer is not complicated. The key points are: mastering the mortar mixing ratio, being familiar with controlling the spray gun distance and angle, and understanding the adjustment of the fiber cutting length. Most operators can operate the equipment independently within 1-2 days with manufacturer guidance. YG provides remote technical support and operation guidance.
A5: Routine maintenance mainly involves three things:
Immediately flush the pipes and spray gun with water after each use to prevent mortar from hardening (this is crucial! Once the mortar hardens in the pipes, cleaning is extremely difficult).
Check the wear of the screw/plunger weekly.
Check the seals and fiber cutter blades monthly.
Following these three points will extend the equipment’s lifespan to over 10 years.
A6: YG’s standard models are 380V/50Hz three-phase (Chinese standard). If the voltage in the destination country is different (e.g., US 220V/60Hz, Nigeria 415V/50Hz), YG can customize the motor and electrical system according to the customer’s local voltage standards. Please confirm the local power supply specifications before placing an order.
