Method · Flooring
An elastic polyurethane that flexes with the slab — for car park decks, helipads and outdoor floors. Anti-slip aggregate is broadcast where grip is needed, then sealed with a UV-stable top coat.
An elastic polyurethane floor coating that flexes with the slab; outdoors it is finished with a UV-stable top coat.
Outdoor floors and substrates that move.
Softer than epoxy, so it is chosen for flexibility rather than maximum hardness.
Layers (built up from the bottom)
The finishing coat on top.
The main polyurethane layer.
Soaks into the concrete so the next layer bonds.
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.
Slab moisture is always measured before a resin floor; damp slabs need a moisture barrier or a moisture-tolerant system.
The working layer is a flexible PU; anti-slip aggregate is broadcast where grip is needed, then sealed with a UV-stable top coat.
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) Coatingthis page | Flexes; outdoors with a UV-stable top coat | Outdoor, moving substrates |
| PU Cement (PU + cement) | 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 hard and seamless — for general indoor floors. PU is softer than epoxy, so it is chosen for flexibility rather than maximum hardness: outdoor floors and slabs that move.
Yes — anti-slip aggregate is broadcast where grip is needed, then sealed with a UV-stable top coat.
Send the area, how the floor is used and a few photos. We check the site and propose the floor that fits.
