Mixing Instructions & Tips

1. Safety First

   • Wear PPE: Work in a well-ventilated area using gloves, safety glasses, and a dust mask.
   • Handle With Care: GFRC mixes contain fine powders that can irritate skin, lungs, and eyes.

2. Ingredient Preparation

   • Accurate Weighing: Precisely measure water, premix, fibres, plasticiser, and pigment (if desired).
   • Separate Dry Mix: Premix colour and plasticiser with the powder to ensure even distribution prior to adding water.

3. Mixing Process

   • Add 80% Premix to Water: Blend thoroughly to avoid lumps and ensure a smooth, uniform mix.
   • Incorporate Remaining 20%: Achieve a homogeneous consistency, scraping sides and bottom to catch dry material.
   • Consistency Adjustments: If necessary, add additional plasticiser (not water) for improved flow.
   • Fibre Addition: Once the desired pourable or sprayable texture is reached, mix in fibres thoroughly.

4. Recommended Mix Proportions

   • Flowable: 20 kg premix, 3 L water, 20 g plasticiser, 40 g 3 mm HD fibres, 350 g 13 mm bundled fibres.
   • Sprayable: 20 kg premix, 2.9 L water, 10 g plasticiser, 40 g 3 mm HD fibres.
   • Hand Packed: 20 kg premix, 2.5 L water, 40 g 3 mm HD fibres, 300 g 13 mm bundled fibres.

Demoulding & Curing

1. Tap Test

   • Sound Variation: As GFRC cures, the tapping sound changes from a dull thud to a crisp, metallic ring—indicating readiness for demoulding.

2. Surface Moisture Check

   • Matte Finish: When the surface no longer appears wet or glossy, it suggests sufficient curing for safe demoulding.

3. Cure Times

   • Minimum 24 Hours: Helps ensure sufficient early strength and prevents cracking upon removal from the mould.
   • Monitor Conditions: Adjust curing schedules based on mix design, ambient temperature, and project requirements.

Applications

• Exterior Cladding & Architectural Elements: Strong yet lightweight material for building façades, ornamental panels, and decorative mouldings.
• Indoor/Outdoor Decorative Features: Ideal for countertops, furniture, planters, sculptures, and unique design accents.
• Restorations & Overlays: Excellent bonding properties for heritage works, renovation projects, or thin overlays over existing surfaces.
