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

Glass Fiber Reinforced Concrete – Advance Techniques – Self Consolidating Face Coat / Backcoat There are situations where you will need to spray a facecoat and hand lay a backcoat, that said if you don’t have to don’t. One technique made possible by Trinic’s GFRC Admix is to self-consolidate a face coat, work it up the edges using a chip brush, then self-consolidate a back coat. There has been some confusion within the GFRC industry about the flexural strength of self-consolidated backcoats. I’v
