FRP (Fiberglass Reinforced Plastic) wall panels are composite sheets made from continuous glass fibers embedded in a resin matrix. They are lightweight, corrosion-resistant, and widely used in commercial kitchens, cleanrooms, clinics, and processing facilities.
GTOFRP panels come in smooth, embossed, fire-rated, and high-strength variants designed to meet hygiene and impact requirements while reducing maintenance.
Fine-tooth carbide circular saw
Jigsaw with fiberglass-rated blades
Diamond grit blades (optional)
Measuring tape and straight edge
PPE: goggles, gloves, dust mask
Table saw with integrated dust extraction
CNC cutting system for precise production work
Industrial vacuum for dust management

Use a straight edge and marker to define your cutting line. Double-check measurements to ensure proper fit during installation.
Place the FRP sheet on a stable workbench. Use clamps to prevent vibration, which helps achieve clean edges.
A fine-tooth carbide blade provides smooth cuts. Always cut with the exposed side facing upward to minimize chipping.
Best for curved cuts or trimming around pipes and corners. Use medium speed to prevent melted resin buildup.
For small cuts, a utility knife can score and snap thin FRP sheets, though edges will require sanding.
Use 120–220 grit sandpaper to smooth rough edges and prepare the surface if painting is planned.
Fine-tooth carbides
Diamond grit for heavy-duty FRP sheets
Always cut outdoors or use dust extraction to reduce fiberglass exposure.
Avoid high-pressure cutting or forcing the blade—the resin matrix can crack under stress.

FRP can be painted successfully if the surface is properly cleaned, sanded, and primed. Without preparation, paint will peel due to the panel's non-porous surface.
Acrylic epoxy coatings
High-bond urethane paints
Industrial-grade primers designed for plastics
Glossy surfaces require sanding
Grease or chemical residues must be removed
Moisture must be fully eliminated
Use TSP cleaner or mild detergent to remove oils and dust.
Lightly sand the FRP using 150–220 grit to create a bonding profile.
Use a plastic-bonding primer for optimal adhesion.
Apply 1–2 coats of high-bond paint using a roller or sprayer. Allow full curing before installing.
Using wood-only blades
Cutting too fast (causes melting)
Forgetting dust control
Painting without sanding
Skipping primer
Applying thick coats that do not cure properly
Cutting tools: $15–$60
Primer: $20–$40 per gallon
Paint: $30–$70 per gallon
Skilled installers require 1–2 hours to cut and finish a standard panel depending on layout complexity.
Food-processing plants, pharmaceutical facilities, and cleanrooms often require factory-coated surfaces for compliance.
Factory gel-coated surfaces last longer than painted finishes, reducing long-term maintenance.

1. What is the best tool for cutting FRP panels?
A fine-tooth carbide circular saw produces the cleanest results.
2. Can you paint FRP panels installed in kitchens?
Yes, but use food-safe coatings and proper surface preparation.
3. Does FRP dust pose health risks?
Dust should be minimized; use protective gear and proper ventilation.
4. How long does paint last on FRP?
With correct preparation, painted FRP can last 3–7 years in normal environments.
Knowing how to cut FRP panels and understanding whether you can paint FRP helps contractors complete projects more efficiently and professionally. With proper tools, surface preparation, and coating selection, FRP panels can be modified, refinished, and adapted to meet diverse installation needs. GTOFRP continues to support installers with reliable materials, technical data, and step-by-step installation guidance.
