1. Standard Working Process of GRC Spraying Machine
Different from ordinary cement plaster machines that only deliver pre-mixed mortar, the GRC spraying machine runs a dual-channel synchronous workflow to integrate base mortar and reinforcing glass fiber during spraying, with seven clear operational steps:
- Raw Material Preparation & Inspection: Prepare raw materials following GRC production standards: fine aggregate, cement, mortar, and alkali-free glass fiber roving. Filter the mortar to remove large particles that may clog pipelines, and check fiber rolls for uniform thickness to guarantee consistent cutting later.
- Mortar Loading into Main Hopper: Pour the well-proportioned cement mortar into the feeding hopper of the GRC machine. The built-in stirring blade keeps the mortar from settling and maintains stable fluidity for long-duration continuous production.
- Screw Pump Constant-Pressure Mortar Delivery: A wear-resistant screw pump transports mortar steadily through one delivery hose toward the spray gun. This pulse-free pumping system ensures even mortar output without sudden flow fluctuations.
- Automatic Glass Fiber Chopping & Separate Conveyance: The independent fiber feeding module cuts long glass fiber rovings into customized short filaments via a high-speed rotary chopper. The chopped fibers travel through a second dedicated air tube to the nozzle separately from the mortar.
- On-Nozzle Synchronous Mixing: The cement mortar stream and chopped glass fiber strands converge precisely inside the spray gun head. Compressed air atomizes the mixed material evenly, so glass fibers distribute uniformly across the entire sprayed layer without agglomeration.
- Layered Spraying & Manual Compaction: Spray the mixed GRC material onto custom molds layer by layer to reach the designed product thickness. Workers compact each fresh-sprayed layer with rollers to eliminate air bubbles, boosting the finished component’s tensile and flexural strength.
- Full Pipeline Self-Cleaning & Storage: After finishing daily production, inject clean water into the hopper and activate the circulation cleaning function. The water flushes residual mortar out of the pump, hoses, and spray gun to stop cement residue from hardening and blocking internal components. Clean and store glass fiber parts in dry storage to prevent moisture damage.
7 Core Features of YG GRC Spraying Machine
Combined with the core difference table that distinguishes GRC equipment from regular spray plaster machines, the GRC spraying machine owns seven exclusive standout features that ordinary mortar spraying devices lack:
- Dual-Tube Synchronous Mixing Spraying System: The most iconic feature separating it from general spray plaster machines is the two independent transport channels for mortar and glass fiber. The materials only mix at the spray nozzle, which prevents fiber tangling inside the pump and ensures uniform fiber distribution inside finished GRC products.
- Adjustable Automatic Glass Fiber Chopping Module: The built-in rotary chopper supports customizable glass fiber cutting lengths. Manufacturers can adjust fiber size based on the strength requirements of different GRC components, from thin decorative moldings to large landscape sculptures.
- Pulse-Free Wear-Resistant Screw Pump Conveyance: YG equips every GRC machine with upgraded anti-abrasion screw rotors and stators. The pump delivers consistent mortar pressure with zero pulsation, creating smooth product surfaces and cutting down post-production polishing work.
- High Production Efficiency & Dramatic Labor Savings: One complete set of GRC equipment replaces 6 to 10 manual workers performing hand lay-up GRC production. The machine can complete dozens of decorative moldings or small sculptures per hour, drastically shortening production lead times for orders.
- Exclusive Compatibility with GRC Special Raw Materials: Unlike regular mortar sprayers that only handle pure cement slurry, this machine is engineered to process the standard GRC raw material combination: cement mortar plus alkali-resistant glass fiber roving. It supports all GFRC formula materials without blockages or material separation.
- Compact Mobile Frame with Universal Casters: The whole machine adopts an integrated compact frame installed with heavy-duty moving wheels. Factories can easily shift the equipment between different production stations, and small-scale producers can transport it to on-site decorative construction locations conveniently. Modular design also simplifies disassembly for maintenance.
- Multi-Layer Safety Intelligent Control Panel: The control system includes overload motor protection, low-pressure alarm, and remote spray start/stop switches. Operators can pause spraying directly beside molds instead of walking back to the main machine unit, lowering safety risks in busy production workshops.
8 Main Application Scenarios of the GRC Spraying Machine
Based on the application comparison in the product difference chart, the GRC spraying machine targets decorative component manufacturing rather than wall plastering work, covering eight mature industry application scenarios:
- European-Style Building Decorative Moldings & Line Profiles: Mass-produce classic European architectural trim, wall lines, cornices, and ceiling moldings. The machine creates lightweight thin-wall GRC moldings with precise surface textures that perfectly replicate traditional plaster craftsmanship.
- Roman Columns, Pilasters & Ornamental Column Components: Manufacture solid and hollow decorative Roman columns, half-columns, and column capitals for villas, high-end hotels, commercial plazas, and church renovation projects. The uniform fiber mixing delivers strong anti-crack performance for tall column structures.
- Exterior Wall Decorative Cladding Panels & Facade Tiles: Produce large-size lightweight GRC facade cladding panels for modern high-rise buildings, shopping malls, and office towers. These panels cut building load weight while retaining customizable surface textures such as stone grain.
- Landscape Sculptures, Artificial Rockeries & Stone Imitation Products: Ideal for manufacturing complex-shaped landscape artworks: garden sculptures, fake rock walls, mountain rockery sets, artificial stone benches, and decorative flower beds. The spraying technology easily forms curved, irregular surfaces that hand molding struggles to replicate.

8 GRC Spraying Machine Purchasing Guide
Many buyers confuse the GRC spraying machine with ordinary mortar plaster machines when comparing the spray plaster machine price. Follow this 8-step professional purchasing guide to select the most suitable GRC machine and avoid costly wrong purchases:
- Clarify Your Main Production Products & Daily Output: First, confirm the types of GRC components you produce most (small moldings, large sculptures, facade panels, etc.) and your target daily production volume. Small decorative workshops can choose compact small models, while export-focused mass-production factories need high-output industrial GRC equipment.
- Verify the Dual-Channel Fiber Spraying Core Function: The core difference between a professional GRC spraying machine and regular mortar sprayers is the independent glass fiber chopping and delivery system. Never purchase ordinary cement plaster machines if you need to manufacture GRC parts, as they lack the fiber mixing function and cannot produce qualified GRC components.
- Inspect Screw Pump Material & Wear Resistance Level: Focus on the material of the pump rotor and stator. Alloy wear-resistant pump parts have far longer service life than rubber standard pumps. Lower-quality pumps will wear out quickly with long-term GRC mortar feeding, raising frequent spare part replacement costs later.
- Check the Adjustable Fiber Chopping Module Function: Confirm the machine supports adjustable fiber cutting lengths. Factories producing multiple types of GRC products need flexible fiber length adjustment to meet different tensile strength standards of finished components.
- Evaluate Machine Mobility Based on Workshop Layout: If your production line requires moving equipment between multiple molds daily, select models equipped with heavy-duty universal moving casters. Fixed production stations can choose heavy-duty stationary industrial models with higher output power.
- Compare Full Configuration Instead of Only Checking Spray Plaster Machine Price: When comparing quotations and spray plaster machine price from multiple suppliers, carefully check the complete accessory list: spray gun assemblies, dual delivery hoses, spare pump rotors, fiber cutting blades, and operation manuals. Many cheap suppliers cut essential accessories to lower upfront quotes, creating hidden extra costs after delivery.
- Confirm Export Certifications If You Ship Products Overseas: For manufacturers that export finished GRC components to Europe or Southeast Asia, select brands with complete CE certification and multilingual technical documents like YG.
- Audit Brand Global After-Sales Service & Spare Parts Supply: Avoid unknown small manufacturers with no overseas after-sales support. Reputable brands such as YG maintain permanent spare parts inventory and online remote technical guidance for global clients, preventing long production downtime if the machine breaks down during busy order periods.
