These polypropylene fibres are a great alternative to animal hair. The fibres are added to lime mortars to add tensile strength.

Polypropylene Fibres can be used as a mortar addition to replace the historic use of animal hair in a lime mortar. Polypropylene Fibres have similar properties to animal hair, they help to mitigate against cracking from freeze/thaw cycles and shrinkage and improve the impact and fire resistance. They can also help to increase the load spread of a render and are particularly useful when a mortar is used for specific purposes like bedding slate and rendering onto lath.
Fibres like other types of synthetic offerings they have proven to be an extremely effective and honest alternative to hair. They are not as traditional as animal hair, however they are much cheaper and simpler to use and they do not degrade in the same way, meaning they can be added to premixed mortars.
We supply two types of fibres:
– Polypropylene Fibres – Simple straight fibres, available in two lengths, 12mm and 19mm.
– Bellmix Flock Fibres – Available in 18mm lengths. As a “Flock” it differs too many other synthetic types as the base fibre has undergone a “Flocking” process where additional smaller fibre particles are bonded onto its surface creating a greater surface contact area for the mortar matrix.
