Technical FAQs
Optimal dosage rate ranges from 0.3 to 1.5 kg/m³ of concrete depending on application. For general crack control in residential concrete, 0.6-0.9 kg/m³ is typically sufficient. For industrial flooring and high-performance applications, dosages of 1.0-1.5 kg/m³ may be used.
Polyester fibre offers advantages over steel mesh: uniform 3D distribution, no corrosion issues, easier installation, maintains workability, cost-effective, provides early-age crack control. Compatible with all cement types and concrete additives including plasticizers, superplasticizers, air-entraining agents, and pozzolanic materials.
Storage: Keep in dry, covered area away from moisture. Storage temperature 5°C to 40°C. Shelf life: 5 years under proper storage conditions. UV-stabilized but avoid prolonged direct sunlight exposure.
