Mixing Instructions & Tips

1. Safety First
   • Personal Protective Equipment (PPE): Wear a mask, safety glasses, and gloves; work in a well-ventilated area.
   • Prevent Dust Inhalation: Although silica-free, fine powders can still be irritating—handle carefully.
2. Ingredient Preparation
   • Accurate Weighing: Gather water, premix, fibres, plasticiser, colour (if needed), and any additives in the recommended proportions.
   • Dry-Mix: Combine premix, colour, and plasticiser beforehand to avoid clumping and ensure even dispersion.
3. Water & Premix Addition
   • 80% First: Pour 80% of the premix blend into the water, mixing thoroughly. Scrape sides and bottom to incorporate all material.
   • Remaining 20%: Add the rest of the premix and continue blending until homogeneous. Adjust consistency only with plasticiser.
4. Fibre Incorporation
   • Final Step: Add fibres to the fully mixed base; ensure thorough distribution for optimal reinforcement.
   • Avoid Extra Water: Water addition dilutes strength and alters colour, so rely on plasticiser for flowability adjustments.
5. Example Flowable Mix
   • MACt SF Premix (20 kg): 2.8 – 2.9 L water, 40 g plasticiser, 40 g 3 mm HD fibres, 500 g 13 mm bundled fibres, 15 g MACt Retarder Pro (if needed).
