A thick polyurethane-cement screed for food plants, cold storage and pharma — it survives sudden hot and cold (about –40 to +120 °C, by product) and is hygienic: dense, easy to sanitise and does not support bacterial or mould growth.
A thick screed of polyurethane combined with cement. It survives sudden hot and cold (about –40 to +120 °C, by product) and is hygienic: dense, easy to sanitise and does not support bacterial or mould growth.
Food plants, cold storage and pharma — floors that are hot-washed or see thermal shock.
It is much thicker than a coating — it replaces the floor surface rather than painting it.
Layers (built up from the bottom)
The body of the floor, resistant to loads, impact and chemicals. Laid without joints.
Filler rubbed into the surface pores to prepare the substrate.
Weak surface ground off, cracks and voids filled to a sound, flat base.
The figure shows one typical build-up. The actual layers are decided after we see the site.
Epoxy for general floors; thick PU cement screeds for food, cold storage and hot-wash areas.
Slab moisture is always measured before a resin floor; damp slabs need a moisture barrier or a moisture-tolerant system.
Floors are chosen by how they are used. If another floor fits better, we will say so.
| Floor | Strength | Where |
|---|---|---|
| Epoxy | Smooth seamless floor, easy to clean | Indoor factory, showroom, lab |
| Epoxy ESD | Drains static to earth through a grounded layer | Data center, electronics |
| Polyurethane (PU) Coating | Flexes; outdoors with a UV-stable top coat | Outdoor, moving substrates |
| PU Cement (PU + cement)this page | Thick & tough, survives sudden hot/cold + hot-wash | Food, cold storage, pharma |
| Polyurea | Sets in seconds, extremely tough | Extra-high durability areas |
| PMMA | Fast cure — the floor reopens the same day | Car park deck, floors that must reopen fast |
| STPE | Goes down on damp (not wet) slabs | Basin floors, enclosed damp areas, high-moisture slabs |
| FRP Lining (resin + glass fiber) | For severe chemicals, mainly strong acids | Treatment & chemical floors |

The floor area, the state of the substrate (whether cracks, chips or moisture need repair first), the type and build of the finish, the chemicals and traffic it must take, and the hours we can work. Send photos and drawings on LINE and we will check the site and quote.
Epoxy is a hard, seamless finish for general indoor floors. Polyurethane (PU) cement is far thicker than a coating — it rebuilds the floor surface, and takes sudden hot and cold and hot-washing.
A damp slab needs a moisture barrier or a moisture-tolerant system. For high-moisture slabs and enclosed damp areas there is STPE, which goes onto damp (not wet) slabs, often with no primer. We measure the moisture before we choose.
Send the area, how the floor is used and a few photos. We check the site and propose the floor that fits.
