A hospital has no single floor type. Corridors, patient rooms, sterile zones and rooms housing electrostatic-sensitive equipment place different requirements on a floor, and a coating system only suits a hospital when it is chosen zone by zone. This article sets out a zoning framework, 4 core requirements and verification methods for epoxy flooring in hospitals. This article does not claim that any Kadier coating system is antibacterial, meets a medical standard, or achieves a specific electrostatic-discharge resistance range — those matters can only be confirmed with the manufacturer TDS and certification.
Zoning table: choose by zone, not in general
| Zone | Top priority | Verification note |
|---|---|---|
| Corridors, common areas, lobbies | Cleanability, slip resistance, wear resistance under foot traffic and trolleys | Seamlessness, roughness when wet, wear on main walkways |
| Patient rooms, clinics | Thorough cleaning, resistance to repeated cleaning and disinfectant chemicals | Actual chemical list in use, wall bases, joints |
| Operating theatres, ICU, sterile zones | Highest cleanability, absolute seamlessness, resistance to high-frequency disinfection | Curved wall bases, no grout joints trapping dirt, trial of the real cleaning process before handover |
| Laboratories, rooms housing electrostatic-sensitive equipment | An added electrostatic discharge (ESD) control requirement alongside cleanability | Continuous earthing grid, resistance measurement after application and re-measurement at intervals |
Treating all zones as one single “hospital floor standard” is a common mistake: applying an ESD system where ESD is not needed wastes money unnecessarily, while using an ordinary system where ESD is needed will not meet operating requirements.
4 core requirements
1. Seamless, impermeable, coved wall bases
Hospital floors must be seamless, joint-free and impermeable, so they create no dirt-trapping points or microbial build-up. A curved wall base (cove base) removes the 90° angle between floor and wall — the hardest place to clean. Verify by eye, with lighting, and by direct inspection of every joint and wall base, not only the middle of the room floor.
2. Resistance to the cleaning and disinfectant chemicals actually used at that hospital
There is no “standard hospital” chemical list shared by every facility. Each hospital must draw up a real list: the names of cleaning and disinfectant chemicals, their actual dilution concentrations, frequency and form of contact, then check it against the manufacturer chemical-resistance table for the correct coating system. Cleaning chemicals and disinfectants are also “chemicals” that must be on the list, not only specialist chemicals. Antibacterial additives (for example silver ions) are an option in the formulation of a particular system, not a default property of all epoxy coatings — so it must not be assumed that every epoxy floor is antibacterial.
3. Slip resistance when wet, balanced against ease of cleaning
Wet zones such as washrooms and instrument-washing areas need slip resistance, but the rougher a surface, the harder it is to clean thoroughly. Roughness must be chosen zone by zone, and slip resistance when wet tested by a method agreed in advance, rather than judged by eye alone.
4. Electrostatic discharge control — only in zones that require it
ESD applies only to zones with electrostatic-sensitive equipment or an electrostatic-discharge control requirement. The resistance ranges of the ANSI/ESD S20.20 standard in general are classified as follows: conductive below 1×10⁶ Ω; static dissipative from 1×10⁶ to 1×10⁹ Ω. These are the ranges of the general standard, not the resistance range of the StatGuard system or any Kadier system — the range of each system follows its TDS. An ESD system needs a continuous copper earthing grid and must have its resistance measured after application and re-measured at intervals during operation. See the StatGuard anti-static coating system for the anti-static system group in general, and check the TDS before applying it to a specific zone.
Notes on odour, VOC and time before a room returns to use
A low-VOC or fast-curing system can help shorten a hospital disruption period, but the specific time before a room returns to use depends on the TDS and the actual application conditions. This article promises no specific number of hours, and customers should agree this time in the contract for each project.
Zone-by-zone verification checklist
- Draw up the actual list of cleaning and disinfectant chemicals and check it against the manufacturer chemical-resistance table for the correct system.
- Check seamlessness, curved wall bases and every joint by eye and with lighting.
- In ESD zones: check the continuous earthing grid, measure resistance at multiple points, and record results by location.
- Check slip resistance when wet in wet zones by the agreed method.
- Trial the real cleaning process before handing over each zone, rather than accepting the whole hospital under one joint report.
- Draw up an acceptance report zone by zone, with a list of points to be fixed (if any).
Operation: daily cleaning and early failure monitoring
During operation, early failure points must be monitored: edge lifting at wall bases, wear on trolley routes, discolouration or surface softening from a newly introduced disinfectant chemical. When a sign appears, the chemical log and cleaning process must be checked before concluding the cause, because a new chemical may be the culprit rather than floor quality.
Frequently asked questions
Is every epoxy floor antibacterial?
No. Antibacterial properties depend on additives in the formulation of each system and must be supported by manufacturer evidence. It must not be assumed that every epoxy floor is antibacterial or reduces hospital infections.
Does every zone in a hospital need an anti-static floor?
No. ESD is only needed in zones with electrostatic-sensitive equipment or an electrostatic-discharge control requirement. Other zones are chosen by cleanability, slip resistance and resistance to cleaning chemicals.
Why draw up a cleaning-chemical list before choosing a system?
Because chemical resistance depends on the chemical name, concentration, temperature and actual contact time. Checking a real list against the manufacturer chemical-resistance table is the only way to avoid choosing a system that cannot withstand the disinfectant used daily.
