The system for floors that get cooked, flooded and scrubbed. A polyurethane resin screed is laid at 6 to 9mm and holds through roughly minus 40 to plus 120 degrees, which is why it is the specification behind food and drink production, commercial kitchens, wet processing and cold stores. It is also the most over-specified system in the industry, so this page is as clear about where it is not needed.

A screed is not a thick coating. It is a heavily filled material laid and finished by hand, and the aggregate loading is what lets it survive conditions that take a coating off the floor.
A three-part system laid by hand at 6 to 9mm and closed with a seal coat. The aggregate loading is what carries heat and impact that a coating would simply lift under.
The heaviest build in the FeRFA range aligned to BS 8204-6. It is not a thicker version of a coating; it is a different material doing a different job.
It holds through roughly minus 40 to plus 120 degrees, so boiling discharge, steam cleaning and cold store operation do not debond it from the substrate.
Food and drink production, breweries and dairies, commercial kitchens, wet processing, cold stores, washdown bays and chemical handling. Anywhere heat, water and aggressive cleaning chemicals arrive on the floor together, every day.
A dry warehouse does not need it. On a sound slab carrying forklift traffic and nothing worse, a high build epoxy coating does the same job for a fraction of the cost. Over-specifying a screed is how money gets wasted on an industrial floor.
Grade and thickness come out of three readings taken on site: what temperature the floor sees, where the water has to go, and what is used to clean it.
We record what actually hits the floor: steam cleaning, boiling discharge, CIP washdown or cold store operation. That range sets the grade and the thickness.
Wet areas have to drain. Falls of roughly 1:80 to 1:100 are formed into the screed and run to stainless channels, so water leaves rather than ponding.
Coved skirting carries the floor up the wall, penetrations are sealed and the topcoat is matched to the cleaning chemicals actually used, not a generic chart.
A polyurethane screed is more forgiving of a damp substrate than any coating. At 6 to 9mm, with the right primer, it can often be laid where a thin system would blister. That is a genuine advantage of the material, and it is not a reason to skip testing the slab.
Every installation starts with mechanical diamond grinding and HEPA-extracted vacuum, so dust is controlled under COSHH and the EH40 respirable crystalline silica limit of 0.1 mg/m³. The screed is then terminated properly: anchor grooves cut in at perimeters, doorways, drains and channel edges, so the edges cannot lift under thermal movement. Falls are formed into the screed itself rather than relying on the slab beneath it, and coved skirting is laid as part of the same work.
We attend site, test the substrate for moisture and contamination, and record the temperatures, chemicals and washdown regime the floor has to survive. The system comes out of those findings. If a screed is more than your floor needs, we will say so and specify what is right.
