Fibre For Screed

Fibre for screed can be applied to a floor for a variety of reasons, from levelling out uneven floors to providing an insulation layer for underfloor heating systems. The most important thing is that it is laid correctly, decreasing the chance of costly and time consuming repairs later on. This means getting an experienced screeding professional involved in the process early on.

Correctly specifying a levelling or floor screed starts in the design stage with the architect’s architecturally specified floor finishes and construction tolerances being identified and a strength requirement determined. It should be calculated based on anticipated worst-case service conditions. The level of reinforcement in the screed can also be determined at this stage.

Choosing the Right Fibre for Your Screed: Factors to Consider

This can be in the form of a metal mesh or fibres such as polypropylene that replace metal reinforcement. These are added to the mix during production and uniformly distributed throughout. They can significantly increase the tensile strength of the final flooring layer and reduce the risk of cracking. They can also be used to provide a much quicker curing solution – these screeds will generally be cured by covering with a polythene sheet and lapping, rather than the usual method of leaving for 7 days.

The use of fibres in a dry mix can cause the mixture to stiffen and be slightly more difficult to work. However, this is outweighed by the benefits. It is important to follow the manufacturer’s guidelines when using them and to ensure they are used by the specific type of screed being laid.
