A food factory floor coating has to do more than look clean. It must resist daily wash-down, spills of fats and acids, and steady forklift traffic. In Egypt, dairies, bakeries, beverage plants and pharmaceutical factories face strict hygiene audits. As a result, the floor is often the first surface an inspector checks. This guide compares resin systems whose data sheets name these industries directly.

What Hygiene Audits Expect From a Floor
Auditors look for floors that are seamless, non-absorbent and easy to clean. Open joints, cracks and broken tiles trap residue and bacteria. Likewise, worn concrete releases dust and absorbs spills.
Food safety principles therefore favour continuous resin floors. In pharmaceutical plants, the bar rises further. ISO 14644 classifies clean rooms by airborne particles, and good manufacturing practice adds its own expectations. So the floor itself must not shed particles.
Wet Zones and Dry Zones
Not every area in a plant needs the same floor. For example, a dry packing hall faces mostly trolley traffic. In contrast, a dairy processing area stays wet for most of the day, and crews hose it down often.
Wet zones need slip resistance and full resistance to water and cleaning chemicals. Hot zones, such as areas near ovens or hot-water wash-down, need heat resistance as well. Dry zones, meanwhile, can take a smoother, easier-to-clean finish. Mapping these zones early leads to a better food factory floor coating specification.
Food Factory Floor Coating Options Compared
The data sheets below each list food or pharmaceutical uses.
| Product | Type | Key data from the sheet |
|---|---|---|
| MasterTop 1110 (Master Builders, now Sikafloor-1110) | Water-dispersible epoxy coating | Applicable to damp concrete; non-tainting; 75–100 µm DFT per coat; max service 60 °C |
| MasterTop 1207 (Master Builders, now Sikafloor-1207) | High-build solvent-free epoxy | Anti-slip finish for wet areas; 85 N/mm² compressive (ASTM D695); Shore D 74 |
| Rayston Floor 1175 (Krypton Chemical) | Hygienic, anti-slip epoxy | 65 N/mm² compressive (ASTM C579); bond 2.5 N/mm² (concrete failure); Shore D 75 |
| Sikafloor-264 (Sika) | Epoxy roller and seal coat | ISO 14644-1 class 4 and GMP class A statements; permanent dry heat +50 °C |
| Kemcrete SL (Prokem) | Self-levelling epoxy mortar | Heat resistance from −40 to +120 °C, per its Arabic sheet |
Water-based epoxy for damp concrete
MasterTop 1110 stands out for wet-process plants. Its sheet states that it can go on damp concrete and will not taint foodstuffs. In addition, it lists dairies, abattoirs, bakeries, pharmaceutical factories and commercial kitchens. The sheet gives two coats, with a recoat time of 10 hours minimum and 48 hours maximum at 25 °C.
Anti-slip epoxy for wet areas
MasterTop 1207 and Rayston Floor 1175 both offer slip-resistant finishes. The Rayston sheet lists food and beverage plants such as bakeries, dairies and soft drink makers. Similarly, the MasterTop 1207 sheet mentions food processing and wet areas.
Clean rooms and heat
Sikafloor-264 suits pharmaceutical and clean room areas. Its sheet cites ISO 14644-1 class 4 and GMP class A qualifications. However, its permanent dry heat limit is +50 °C. Where floors face higher heat, a heat-resistant mortar such as Kemcrete SL is worth considering. Its Arabic sheet gives headline claims only, so we confirm full data with the supplier.
Chemical spills in food plants
Food plants rarely use harsh industrial acids, yet they do spill milk, juices, sugars and cleaning agents every day. The Rayston Floor 1175 sheet lists spill tests: sugar solution, citric acid 10% and acetic acid 10% showed no effect. However, lactic acid 10% caused a colour change. That matters in dairies, where lactic acid is common. So, for every food factory floor coating, compare the plant’s actual chemicals with the resistance table in the sheet.
Substrate Preparation
Above all, the concrete must be sound and clean. The MasterTop 1207 sheet asks for concrete at least 28 days old with moisture up to 4%, primed with MasterTop 1200. Likewise, Rayston Floor 1175 and Sikafloor-264 both call for moisture below 4%.
Food plants add another challenge: oil and fat soaked deep into old concrete. Therefore, contaminated areas may need deep grinding or replacement before coating.
Coving, Drains and Details
Hygiene often fails at edges. A sharp floor-to-wall corner collects dirt, so designers usually specify a coved skirting. Moreover, drains and channels need a gap-free bond to the floor.
Key details include:
- Coved upstands at walls and plinths.
- Sealed edges around drains, gullies and channels.
- Correct falls so water does not pond.
- Flexible sealing at movement joints, never coated over.
Practical Execution Steps for a Food Factory Floor Coating
Target crews usually follow this sequence, adapted to the plant’s schedule and specification:
- Map wet, dry and hot zones with the plant team.
- Test concrete strength and moisture, and check for oil contamination.
- Prepare the surface mechanically and vacuum it clean.
- Repair defects and form coves and drain details.
- Prime as the system data sheet requires.
- Lay the body coats and broadcast anti-slip aggregate in wet zones.
- Seal and finish, then cut and seal movement joints.
- Allow full cure before wash-down and production.
Timing matters in a running plant. For instance, MasterTop 1207 gives 18–36 hours between coats and full cure after 7 days. Rayston Floor 1175 also reaches full cure after 7 days. Planning shutdowns around these times avoids rushed handovers.
Working around production
Most plants cannot stop for weeks. Therefore, we usually split the floor into phases, isolating each zone from production. Dust from grinding needs extraction, and odour matters near open food. In this respect, MasterTop 1110 is solvent-free, and its sheet reports a minimal risk of tainting foodstuffs during and after cure.
Common Mistakes
- Using one floor for wet, dry and hot zones alike.
- Coating oil-soaked concrete without deep cleaning.
- Leaving square corners instead of coves.
- Exceeding the heat limit of the chosen resin.
- Starting wash-down before full cure.
- Mixing products from different systems without approval.
FAQ
Can a food factory floor coating go on damp concrete?
Some can. According to its sheet, MasterTop 1110 is a water-based epoxy that tolerates damp concrete. Most solvent-free epoxies, however, need moisture below 4%.
Which floor suits a clean room?
Sikafloor-264 carries ISO 14644-1 class 4 and GMP class A statements in its sheet. Still, the full clean room specification should come from the plant’s design team.
What about hot wash-down areas?
Check the heat limit first. MasterTop 1110 lists 60 °C maximum service temperature. For higher heat, Kemcrete SL’s sheet claims resistance up to +120 °C.
Can we coat over the old tiles?
Usually we advise against it. Broken or loose tiles trap water and residue beneath them, and the coating then fails on top. So we prefer to remove the tiles and reach sound concrete, unless the system supplier approves otherwise in writing.
How should the floor be cleaned?
Follow the cleaning regime in the system sheet. For example, Sika refers to its own Sikafloor cleaning regime for Sikafloor-264.
Conclusion
A good food factory floor coating starts with zoning: wet, dry and hot areas each need a matched system. Sound concrete, coved details and full cure then complete the job.
