Fibre Screed Minimum Thickness?

I’m Andy Parkin, Managing Director of the Multi-Award Winning Speed Screed.

Let’s talk about fibre screed minimum thickness.

Traditional sand and cement screed can go down as thin as 40mm, in a bonded situation, directly onto the concrete substrate. This is defined by the British Standard BS8204-1:2003

With floating construction, the minimum for domestic is 65mm, and 75mm for commercial.

There are other specialist semi-dry screeds that will allow you to go down as low as 10mm bonded, and 35mm for floating construction. These mixes tend to contain the polypropylene fibres, which minimise shrinkage cracking.

Some smoothing compounds also contain micro fibres and can be bonded from 1mm upwards.

I hope that helps and gives you an idea of fibre screed minimum thickness.
