Synthetic resin screed (SR)

Synthetic resin screed (SR) offers numerous advantages and is an important component in modern construction due to its versatile application possibilities. Fillers such as quartz sand, which are mixed with a binder such as epoxy or polyurethane resin during installation, serve as the basis for the floor coating. The synthetic resin allows the screed to harden quickly and gives it special properties such as high load-bearing capacityflexibility and chemical resistance. This makes synthetic resin screed ideal for use in demanding areas where conventional screeds may not be sufficient. However, this type of screed is also associated with comparatively higher material and processing costs.

Areas of application for synthetic resin screed

Synthetic resin screed is extremely resilient due to its special composition. This makes it very suitable for applications in which the floor is constantly subjected to heavy mechanical loads or comes into contact with chemicals. A typical example of this is commercial and industrial applications such as production facilities, warehouses or workshops. Here, heavy equipment such as machines or forklift trucks often exert considerable pressure on the floor, which quickly pushes normal screeds to their limits. Thanks to its high strength and flexibility, synthetic resin screed is able to withstand these high loads in the long term. Even accidents involving falling materials and contact with moisture or cleaning agents do not affect a professionally laid synthetic resin screed.

Other possible applications for synthetic resin screed:

  • Electronics industry: In areas where sensitive technical devices or components are used, electrostatic discharges can cause major damage. With special additives such as carbon fibers or metallic fillers, it is possible to give the synthetic resin screed antistatic properties in accordance with DIN EN 61340-5-1.
  • Food processing: In bakeries, kitchens and butcher's shops, the floor must not only be resilient, but also easy to clean and able to cope with harsh cleaning agents. With its sealed surface and high resistance to chemicals, synthetic resin-based screed is the ideal choice for these applications.
  • Public areas: Whether it's a train station, shopping center, school or hospital - in buildings with high pedestrian traffic, conventional floors wear out very quickly. Synthetic resin screed offers a durable and, if required, visually adaptable alternative to conventional screed types.
  • Renovation or refurbishment: Existing floors with cracks or other visual/technical defects can be quickly repaired or covered with synthetic resin screed and thus reliably protected against the penetration of moisture or chemicals, for example. And all this thanks to the rapid curing within a very short time.

Laying synthetic resin screed

For optimum results, the screed formulation must be individually tailored to the respective requirements and stresses. This requires a specialist company with the appropriate knowledge and experience.

Synthetic resin screed is basically a bonded screed. This means that it is always firmly bonded to the substrate. There are no floating screeds made of synthetic resin.

The processing time until setting depends on the temperature. As a rule, the drying time takes a few days and good ventilation is essential. Under good conditions, synthetic resin screed can be walked on after 2-3 days.

Caution: Hazardous vapors may form if ignited.

The advantages of synthetic resin screed at a glance

Due to its comparatively high cost, synthetic resin screed is rarely used, but it does have numerous advantages that are of great benefit in commercial applications:

  1. Fast curing due to polymerization
  2. High load-bearing capacity due to very good compressive, tensile and flexural strength
  3. Seamless surface thanks to jointless installation, which prevents moisture and/or chemicals such as cleaning agents from penetrating the floor and is easy to clean
  4. High chemical resistance due to special chemical composition and polymerization
  5. High wear resistance thanks to compact network structure

Questions and answers about synthetic resin screed

What ingredients are contained in synthetic resin screed?

The basis of synthetic resin screed is fire-dried quartz sand, sometimes also other hard materials such as corundum. Various substances can be used as binders. The most commonly used are epoxy resins (EP), polyurethanes (PUR), polymethyl methacrylates (PMMA) and unsaturated polyester resins (UP).

Is synthetic resin screed suitable for high-traffic areas?

Yes, thanks to its compact network structure, synthetic resin screed has extremely high compressive, tensile and flexural strength as well as high wear resistance. This makes the synthetic floor coating particularly suitable for areas subject to heavy traffic, such as warehouses with forklift traffic, shopping arcades or parking garages.

What surface tensile strength must synthetic resin screed have?
For bonded installation, the required surface tensile strength depends on whether the areas are driven on or not. In areas not subject to traffic, it must be 1 N/mm², whereas in areas subject to traffic it must be 1.5 N/mm².
