GFRC Methods (Glass Fiber Reinforced Concrete) Our customers often have questions about which method to use. • Spray up or self-consolidating facecoat: Use on 3D pieces or on flat surfaces with surface exposure (acid etch, sandblast). • Direct cast no facecoat: Use when there will not be surface exposure (light sanding, form liner).

Direct Cast Glass Fiber Reinforced Concrete Direct cast GFRC is defined as casting GFRC with no facecoat (backcoat with fiber only) directly on to the form. A self-consolidating mix that does not require vibration is used. The result is a finished casting with minimal imperfection, excellent strength and no fiber showing. Making flawless direct castings. The mix: • 50% Cementitious – 90% Portland, 10% Trinic White Silica Fume • 50% Sand – 40-50 mesh works fine; you can blend in some smaller size
