Have you ever seen those exquisite European Roman columns, intricately carved exterior walls, light and airy arched window frames, and lifelike miniature sculptures? They look like stone, feel like cement, but are actually less than half the weight of stone. This is GRC (Glass Fiber Reinforced Concrete). It uses cement as the base material and glass fiber as the reinforcement, retaining the hardness of cement while significantly reducing weight and increasing toughness. The core tool for creating these complex shapes is the GRC shotcrete machine.
GRC stands for Glass fiber reinforced concrete, often written as GFRC. It is a high-performance composite material composed of cement, fine sand, water, additives, and alkali-resistant glass fiber. GRC has outstanding characteristics: lightweight (its density is about one-quarter to one-fifth that of ordinary concrete), high strength, good toughness, and strong plasticity, allowing for the creation of various complex curved surfaces and artistic shapes. It is widely used in building exterior wall decoration, interior decoration, landscaping, and municipal facilities. Whether it’s a modern curtain wall panel or a retro European Roman column, window frame, relief, fountain, or flower pot, GRC can achieve it all. If your project requires reducing labour costs, please contact us now for more product information.

In Which Scenarios Are GRC Spraying Machines Suitable?
- Production of GRC exterior wall decorative panels. GRC exterior wall decorative panels are currently the most mainstream application. Whether it’s European-style Roman columns, lines, and reliefs, or modern-style perforated panels and irregularly shaped panels, professional GRC spraying equipment is needed to ensure quality and efficiency.
- GRC products for landscaping. GRC artificial mountains, GRC flower pots, GRC seats, GRC landscape sculptures, and other landscaping products. These products have complex shapes, making manual spraying difficult; using equipment provides high efficiency and quality.
- Tunnel and subway projects. GRC lining and GRC fireproof panels for tunnels and subways. These projects are typically large-scale, with tight schedules and high-quality requirements; manual spraying simply cannot meet the requirements, necessitating the use of professional spraying equipment.
- Water conservancy and hydropower projects. GRC seepage prevention layers for reservoir dams, aqueducts, canals, etc. These projects have extremely high requirements for the impermeability of GRC, necessitating uniform spraying without voids. Professional spraying equipment is the best choice.
- Interior and exterior wall mortar plastering. Removing the fibre assembly transforms YG’s GRC spraying machine into a high-performance mortar spraying machine. It can spray interior and exterior wall plastering mortar, thermal insulation mortar, waterproofing materials, putty, etc. Suitable for both building construction and decoration.
- Slope protection and tunnel shotcrete. Replacing the spray gun and nozzle with a larger diameter one allows it to be used as a shotcrete machine for slope protection, tunnel shotcrete, foundation pit support, and other projects. One machine can be used on multiple construction sites.
- Art sculptures and handicrafts. GRC art sculptures, film props, theme park landscapes, etc. These products have complex shapes and high surface quality requirements; professional spraying equipment ensures uniform coverage of every detail.
- Old building renovation and reinforcement. Old building exterior wall renovation, structural reinforcement, and other projects. Applying a GRC reinforcement layer not only improves structural strength but also serves a decorative purpose, achieving two goals at once.

UAE Customers Use YG GRC Spraying Machines Case — Dubai Theme Park GRC Landscape Project
Client Background:
A large-scale theme park engineering contractor in Dubai, UAE, undertook the GRC landscape project for a major theme park in Dubai. The entire project required painting over 50,000 square meters of GRC, including artificial mountains, sculptures, and building facades, with extremely complex designs.
Problems Faced:
- The project had a short timeframe of only 6 months, making manual painting impossible; specialised equipment was essential.
- Dubai’s summer temperatures reach 50 degrees Celsius, making outdoor work difficult for workers.
- Theme parks have extremely high requirements for surface quality, allowing no flaws.
- The project’s complex designs, with many curved surfaces and openwork structures, made manual painting extremely challenging.
Solution:
After a global bidding process, the client ultimately selected YG’s GRC painting machine. YG specifically optimised the hydraulic and electrical systems for Dubai’s high-temperature environment, ensuring stable operation even at 50 degrees Celsius.
Usage Results:
- With three machines operating simultaneously, the average daily spraying area reached 1,500 square meters. The entire 50,000-square-meter project was completed in just 35 days, a full month ahead of schedule.
- Even at 50 degrees Celsius, the equipment operated stably without any malfunctions.
- The spraying quality for complex shapes was excellent, with even coverage of every detail and a smooth, aesthetically pleasing surface.
- The owner and supervisor were extremely satisfied with the spraying quality and recommended YG equipment for other projects.
- The three machines have been in use for over four years, with a cumulative spraying area exceeding 300,000 square meters, and are still operating well.
Client Testimonial:
Project Manager Hassan said, “This theme park project was the biggest challenge our company has faced since its inception. 50,000 square meters of GRC, a 6-month construction period, 50-degree Celsius temperatures, and complex shapes—the quality requirements were extremely high. Without YG’s GRC spraying machines, we simply couldn’t have completed this project. We’ve since undertaken several large projects, all using YG equipment. YG has become our company’s sole designated supplier of GRC equipment.”

Frequently Asked Questions about YG GRC Spray Painting Machines
A1: YG’s GRC spraying machine can spray 5- 30 mm thick layers in one pass.
If a thicker GRC layer is needed, multiple coats can be applied, allowing each coat to partially set before applying the next. This ensures good adhesion between each layer and prevents delamination.
Most architectural GRC is 15- 20 mm thick and can be achieved in one pass, making it very efficient.
YG’s GRC spraying machine is highly adaptable to various glass fibers:
* Fiber type: AR alkali-resistant glass fiber roving.
* Fiber tex: 2400tex, 3000tex, and 4800tex are all acceptable.
* Cutting length: 10- 30 mm adjustable, set as needed.
We recommend using 2400tex or 3000tex AR alkali-resistant glass fiber for the best spraying effect and most uniform fiber dispersion.
A3: YG’s GRC painting machines have been exported to dozens of countries worldwide. Major markets include: Malaysia, Indonesia, Thailand, Vietnam, India, UAE, Saudi Arabia, Qatar, Kuwait, Australia, New Zealand, USA, Canada, Mexico, Brazil, Russia, Germany, Poland, South Africa, Nigeria, and Kenya.
