PU self levelling flooring is a poured polyurethane floor, usually 2 to 4 mm thick, that flows out into a smooth, continuous surface with no joints or grout. It is slightly resilient underfoot, quieter than tiles or epoxy, resists yellowing, and can be run up the walls as a coved skirting. That combination makes it one of the most popular floors for hospitals, pharma cleanrooms, laboratories and modern commercial interiors.

Why hygienic spaces choose it

No joints. Tile grout and panel seams collect dirt and bacteria. A poured floor has nowhere for them to hide.

Coved skirting. The floor curves up the wall, so corners can be cleaned in one pass.

Easy disinfection. The sealed surface handles repeated cleaning with hospital and pharma disinfectants.

Comfort and noise. Its slight give is easier on staff who stand all day, and it cuts trolley and footstep noise.

Colour stability. PU topcoats resist yellowing, so light colours stay light.

Where it's used

  • hospital wards, ICUs, operation theatre complexes and corridors
  • pharma production, packing and QC rooms
  • research, testing and diagnostic laboratories
  • electronics assembly and clean rooms, with an antistatic grade
  • offices, showrooms and design-led interiors
  • schools, clinics and institutional buildings

PU or epoxy self levelling?

Both are poured, smooth and jointless. PU is softer, quieter, more flexible and more colour stable. Epoxy is harder and usually a little cheaper. For hospitals, labs and cleanrooms, PU is generally preferred. For warehouses and packing halls with more wheel traffic, epoxy self levelling or EPU often suits better.

Antistatic grades

Where static discharge matters, such as electronics assembly, some OTs and powder handling areas, a static dissipative version is laid over a copper grid and conductive primer, then tested for resistance. See our antistatic ESD flooring page.

Installation

  1. Survey: moisture test, flatness check and inspection of the existing surface
  2. Preparation: grinding, crack repair, screeding of low areas
  3. Coves: formed at walls and around plinths where required
  4. Primer: chosen for slab conditions
  5. Pour: PU self levelling material spread to thickness and de-aerated with a spiked roller
  6. Topcoat: optional satin or matt finish to reduce glare and hide fine scratches

Foot traffic usually returns in about a day. Beds, trolleys and full cleaning follow after the specified cure time.

Working in occupied buildings

Hospitals, labs and offices rarely close. We phase work room by room, use low-odour products and coordinate with infection control, QA or facility teams.

FAQs

How thick is PU self levelling flooring?

Usually 2 to 4 mm, depending on traffic and use.

Can it be laid over existing tiles?

If the tiles are firmly bonded and flat, yes, after grinding and filling joints. Loose tiles must be removed.

Is it suitable for operation theatres?

Yes, and an antistatic grade is available where required by the hospital specification.

Can it be used in wash rooms with drains?

Not on its own, since it settles flat. Wet rooms need a sloped system such as PU concrete.
