Approx 9mm long fibres to improve the durability of cementitious screed and toppings by inhibiting the formation of small cracks which occur because of plastic shrinkage. Durability is further enhanced due to fibres being coated with a special dispersing agent. Improves fibre bond and eliminates the requirement for shrinkage control wire mesh reinforcement. Fibres may be used in any cement based screed, approx. 1kg per cubic metre).
