When it comes to the durability of screed, one question is becoming increasingly important: Are fibers alone enough to protect the floor from cracks and deformation? The answer is simple – they are not.

What (don’t) fibers do in screed?

Synthetic fibers, especially polypropylene (PP), are often added to screed mixes. Their main role is to control shrinkage and reduce microcracks during the initial drying phase. However, fibers are not reinforcement. They are additives – not a system that carries load.
PP fibers have a lower density than screed, which often causes them to float toward the surface. This further reduces their effectiveness in the one place where strength is needed – the middle of the screed layer, where stress builds up.
On the other hand, the solidian PRIMAFLOOR glass mesh, made from silicate fibers, has a density almost identical to the cement mix. This means it stays exactly where it should – evenly distributed within the body of the screed.

Why do some contractors oppose using mesh?

Some contractors still prefer using fibers because they believe it's sufficient – and that mesh is just an unnecessary delay. But that “saved” minute often turns into hundreds of euros in repairs and claims down the road. Contractors who have already switched to solidian PRIMAFLOOR know: good preparation is the fastest and most cost-effective guarantee of quality.

Why choose solidian PRIMAFLOOR?

  • Easy handling – the roll weighs just 6 kg, making it easy to carry and install
  • Less overlap needed – compared to traditional metal mesh, less overlap is required, reducing waste and speeding up installation
  • Moisture and chemical resistance – it won’t rust or deteriorate over time
  • True reinforcement – it absorbs stress and prevents cracking

Real reinforcement for long-term performance

Fibers have their value. They can help with shrinkage and microcracks. But fibers – yes, just not without solidian PRIMAFLOOR glass mesh. Only this combination provides both flexibility and the mechanical strength needed to protect screed over the long term.

solidian PRIMAFLOOR has already become a standard among contractors who want a fast solution, easy handling, and lasting performance.
Instead of settling for “good enough,” they choose what’s proven to work.
