A GRC spray machine is a specialized construction device designed to spray glass fiber-reinforced concrete mixtures evenly onto surfaces, combining cement mortar and chopped glass fibers in one continuous application. Unlike manual troweling or simple mortar sprayers, this equipment disperses fibers uniformly throughout the wet mix as it sprays, creating a dense, crack-resistant GRC layer with consistent structural strength across every section of the workpiece. It serves as the core production tool for precast GRC factories and on-site GRC construction teams, enabling faster project delivery and more reliable material performance than fully manual application methods. A high-quality GRC machine forms the foundation of efficient, repeatable GRC production for both precast and on-site projects.

Applications of GRC Spray Machine
This versatile GRC equipment supports a wide range of construction and manufacturing scenarios, each with specific performance requirements.
- Architectural decorative GRC components: Manufacturers use it to produce exterior wall panels, cornices, relief sculptures and facade elements, where uniform fiber distribution ensures long-term weather resistance and structural stability.
- Landscape and garden engineering: Teams apply GRC layers to create artificial rockwork, decorative retaining walls and themed landscape structures, where the spray method easily follows complex curved shapes that are difficult to finish by hand.
- Municipal and infrastructure repair: For tunnel lining reinforcement, concrete surface restoration and anti-corrosion lining work, the spray method delivers fast, even coverage that bonds tightly to existing concrete substrates.
- Industrial facility protection: The equipment also applies GRC protective layers to warehouses, sewage tanks and industrial workshops, creating durable, wear-resistant surfaces that extend the service life of concrete structures.
Features of GRC Spray Machine
The design of a GRC spraying machine focuses on three critical priorities for construction teams: adjustable output, consistent material mixing, and reliable on-site operation.
- Variable-speed delivery system: The equipment supports a rotation speed range of 20–200r/min and a delivery capacity of 300–1600kg/h, so operators can fine-tune spray flow to match different mix viscosities, coating thicknesses and project requirements. This adjustability prevents material sagging on vertical surfaces and reduces waste caused by excessive output.
- Integrated mixing and spraying workflow: The 60L mixer unit prepares homogeneous GRC slurry continuously, feeding directly into the spray system to avoid segregation of fibers and mortar. This integrated design ensures every sprayed layer contains evenly distributed glass fibers, which directly improves the impact resistance and flexural strength of the finished GRC surface.
- Extended effective workspace: With a 4.5m effective spray reach, the unit covers large wall panels, curved architectural components and irregular landscape structures without frequent repositioning. This extended range cuts down on setup time between work zones and keeps production efficiency high throughout the workday.
- Robust industrial power configuration: Powered by a 2.2–4.0kw motor and compatible with standard 380 V 50 Hz industrial power supply, the equipment handles long hours of continuous operation on construction sites without performance drops or frequent overheating issues.


What the YG GRC Spray Machine Can Produce?
Architectural elements. Cornices, columns, window surrounds, and decorative moldings. GRC’s ability to replicate intricate details makes it ideal for architectural restoration and new construction.
Panels and cladding. Lightweight wall panels, facade cladding, and curtain wall systems. GRC panels are durable, weather-resistant, and can be produced in virtually any color or texture.
Furniture and fixtures. Benches, planters, tables, and custom furniture pieces. GRC’s strength-to-weight ratio allows for thin, elegant designs that are still durable enough for public spaces.
Landscape products. Fountains, sculptures, and decorative garden features. GRC withstands outdoor exposure and freeze-thaw cycles better than many other materials.
4 FAQs About YG GRC Spraying Machine
A: A GRC machine integrates fiber chopping and mortar spraying into one synchronized process, ensuring glass fibers disperse evenly throughout the mix. Standard mortar sprayers only apply cement slurry without controlled fiber addition, so they cannot produce structural-grade GRC layers.
A: Yes, the equipment supports adjustable fiber feed rates and spray output settings, so it can adapt to common fiber lengths and mix proportions used in standard GRC projects. Operators can tune parameters to match each specific mix design for optimal results.
A: The unit runs on a standard 380V 50Hz three-phase power supply, which is widely available on most industrial and construction sites. It requires a flat, stable placement area and access to clean water for material mixing and post-use cleaning.
A: Under optimal conditions, the equipment reaches a production efficiency of 200–400 square meters per hour, with a material delivery capacity ranging from 300 to 1600 kilograms per hour. Actual output varies based on coating thickness and mix formulation.
