2.4.1.1 PU-Crete
The floor covering is a multi-component polyurethane modified with special fillers. It is typically carried out in layer thicknesses from 2 - 12 mm. The layer thickness of the chosen floor depends on the desired properties, as the floor covering can be made with different degrees of slip resistance, surfaces, colors, degrees of finish and resistance. In addition, very fast curing times can be achieved. PU-Crete floors can be made, which are fully usable after only five hours at temperatures of min. 10 °C. The flooring is chosen more often for its functionality and resistance than for aesthetic reasons.
Areas of application
The floor covering can be a solution for the food industry, dairies, pharmaceutical and chemical plants, laboratories, freezer rooms, etc., which are exposed to high chemical and mechanical loads, impacts, heat shock and steam cleaning, etc.
The floor covering is compact, impermeable and practically inert, non-biodegradable and does not promote the growth of bacteria etc., which makes it suitable for areas where the highest level of hygiene is required.
The floor covering is not UV resistant. This means that if it is exposed to sunlight or other UV effects, there is a risk that certain colors will turn yellow.

Main benefits
• Resistant to a wide range of chemicals from strong acids to bases, fats, oils and solvents, etc.
• Higher wear resistance than traditional seamless coatings
• Depending on specification and layer thickness, the floor covering can withstand and maintain its physical properties under temperature influences from -40 °C up to +160 °C
• On concrete, the adhesion strength can become stronger than the cohesion strength of the concrete
• Taste and odor neutral and emits no pollution or VOCs (volatile organic compounds)
• Less sensitive to moisture than similar products and the floor covering can thus be laid out on relatively freshly poured concrete after suitable pre-treatment
• Can be used as an antistatic floor covering

Assessment of substrate
An important parameter for a good result is the substrate.
Before starting the work process, the nature of the substrate must be carefully examined and checked for, among other things, cracks, loose areas and whether the surface tensile strength meets the specific requirements of the chosen PU-Crete. For most manufacturers, the minimum requirement for the surface tensile strength of the substrate will usually be ≥ 1.5 MPa. In addition, you should pay attention to whether the manufacturer sets special requirements in connection with various terminations and any locking grooves. It is important - and common to all types of floor coverings - that the substrate is checked and complies with the manufacturer's instructions before the floor covering is carried out.
