In Thailand, a company specializing in architectural GRC (Glassfiber Reinforced Concrete) elements was struggling to meet rising demand. Their production line relied on manual mixing and hand‑spraying of cement, sand, water, and chopped glass fibers. The process was slow, the fiber distribution was uneven, and the rejection rate was high. Each complex decorative piece—cornices, columns, artificial rocks—required skilled workers, and even then, the strength varied from batch to batch.
The result was immediate. The Thai factory doubled its daily output, reduced labor from five workers to three, and increased product strength by 30% according to their in‑house tests. Reject rates fell by more than half.

Three Problems That Plagued Manual GRC Production In Thailand
The Thai manufacturer’s experience reflects three common challenges across the decorative concrete industry in Southeast Asia.
Problem 1: Inconsistent Fiber Distribution
Mixing chopped glass fibers by hand or with a low‑quality mixer leads to clumping. Some areas of the finished piece have too many fibers (weak in compression), others have too few (brittle). This causes rejects and field failures. Manual spraying cannot control the fiber‑to‑mortar ratio precisely.
Problem 2: Low Production Speed
A skilled worker spraying by hand can cover only about 50‑80 m² per day. With Thailand’s rising labor costs and high demand for architectural elements, manual methods cannot keep up with project schedules.
Problem 3: High Material Waste
When mixing small batches manually, overspray and leftover material are common. The cement and fibers are expensive. Waste directly cuts into profit margins.
The YG grc machine solved all three problems by automating mixing, pumping, and spraying.
Why The YG GRC Spraying Machine Transformed The Thai Factory?
The grc spray machine operates on a simple but effective principle: a screw pump delivers the mortar mixture while a separate system introduces chopped glass fibers at the nozzle. The variable‑speed motor (20‑200 r/min) allows the operator to adjust output on the fly.
Consistent Fiber Distribution Every Time
Because the machine meters the fibers and mortar together at the nozzle, every square centimeter of sprayed material receives the same fiber content. The Thai factory tested panels from the same batch and found strength variation below 5% – compared to 20‑25% with manual methods.
High Output, Low Labor
With a productivity range of 200‑400 m² per hour, the grc machine replaced five manual sprayers with one machine and two helpers. The horizontal boom reaches 4.5 meters, allowing the operator to cover large molds or wall sections without repositioning the machine. The Thai factory increased daily output from 150 m² to 300 m² with fewer workers.
Reduced Waste and Faster Cleanup
The screw pump delivers material only when the trigger is pulled. No continuous flow means no messy overspray. The 60L hopper is sized for typical batch cycles, and the smooth interior surfaces make cleaning quick. The Thai manager reported that material waste dropped by 40%.

Real Feedback From The Thai Production Team
After three months of using the YG grc machine, the factory owner shared his results.
- Output: Doubled from 150 m² per day to over 300 m².
- Workforce: Reduced from five workers to three (two on the hose, one on mixing).
- Strength: Compressive strength increased by 30%, verified by lab tests on sample panels.
- Reject rate: Dropped from 12% to under 4%.
- Payback period: The grc machine paid for itself in less than five months through labor savings and reduced waste.
The production manager said, “We used to reject one out of every eight panels because of fiber clumps or weak spots. With the automated grc spray machine, we hardly see those defects. The adjustable speed lets us spray thin layers for complex molds or thick layers for flat panels. It is the best investment we have made.”
An operator added, “The machine is easy to learn. I set the speed, pull the trigger, and move the hose. The spray pattern is consistent. Cleanup takes 20 minutes instead of an hour with manual tools.”
Which GRC Equipment Configuration Fits Your Shop?
Use this quick guide based on your production volume and available power.
- Small shop, occasional pieces (200‑500 kg/h needed): Solution 1 or 2 (2.2‑3.0 KW machine + 1.5 KW mixer). Good for small decorative items and repair work.
- Medium production (500‑1000 kg/h): Solution 3 or 4 (3.0‑4.0 KW machine + 2.2 KW mixer). The Thai factory chose Solution 4. Handles most architectural elements.
- High‑volume, continuous operation (1000‑1600 kg/h): Solution 5 (4.0 KW machine + 5.5 KW mixer). For factories making large panels, columns, or production line work.
All configurations require an air compressor. For a grc spraying machine, YG recommends an 11 KW screw air compressor (0.6‑0.8 MPa working pressure matches the machine’s requirement). The machine operates on 380V, 3‑phase, 50 Hz power – standard for Thai industrial zones.
