High performance crimped monofilament 6 mm long polypropylene fibres.


To improve the durability of cementitious screeds and toppings by inhibiting the formation of small cracks, which occur because of plastic shrinkage and settlement due to premature drying.
Durability is further enhanced due to increased residual strength, resulting in improved abrasion, impact and spalling resistance.
Even distribution throughout the mix is due to fibres being coated with a special dispersing agent. Improves fibre bond and eliminates the requirement for shrinkage control wire mesh reinforcement. Isocrete PP Fibres are intended for use in the Isocrete products K-Screed, Fast-K, Screedfast, Isogran, Isopol SBR and other polymer modified and conventional cementitious
screeds and toppings. Please note that Isocrete PP Fibres cannot be used as a replacement for structural steel reinforcement.


Normal good curing practices for conventional screeds or toppings must be strictly followed. It is recommended to cover the surface with polythene sheeting and lap all joints as soon as practicable following finishing works. Leave in position for at least 7 days. For Isocrete proprietary screeds, cure as recommended in the relevant product data sheet.
