Full System Specification

Food Grade PU Screed

Thermal-shock, chemical and hygiene compliance in food environments.

System overview

A polyurethane cementitious screed installed at 4–9 mm, engineered specifically for HACCP, BRC and SALSA-audited food and beverage environments. PU screed handles thermal shock (from steam clean and –40°C freezers), aggressive food acids, oils and continuous wash-down.

The default specification for kitchens, bakeries, dairies, meat processing, breweries and cold stores.

Typical thickness

4 mm (standard), 6 mm (wash-down), 9 mm (thermal shock and MHE).

Chemical resistance

Excellent resistance to lactic, acetic and other organic acids, animal fats, blood, sugars, alkalis, solvents, hot water, steam and CIP chemistry. Rated for daily hot wash-down and steam clean.

Suitable environments

  • Commercial and industrial kitchens
  • Dairies, bakeries and ready-meal production
  • Meat, poultry and fish processing
  • Breweries, distilleries and beverage plants
  • Cold stores, chill rooms and blast freezers

Where it's not the right choice

  • Areas requiring a smooth decorative aesthetic (specify epoxy)
  • Non-HACCP environments where a lighter PU coating would suffice on cost

Key benefits

  • Thermal shock resistance –40°C to +120°C
  • HACCP, BRC and SALSA compliant
  • Aggressive chemical and organic-acid resistance
  • Impact and abrasion rated for heavy MHE
  • Seamless, coved and audit-ready

Slip resistance options

  • R11 — dry food-prep
  • R12 — general wet food-prep
  • R13 — wet, greasy or ramped food areas

Colour and finish options

  • Standard PU screed palette (terracotta, mid-grey, cream, blue, green, red)
  • Zone-coding for HACCP flow (raw / cook / dispatch)
  • Contrast coloured coves and skirtings

Installation process

  1. Step 01

    Survey and audit review

    We attend site with your QA or ops team, confirm audit standard, chemical exposure, thermal profile and cleaning regime.

  2. Step 02

    Substrate preparation

    Diamond grinding or captive shot-blasting to CSP 4. Slabs green enough for direct application are accepted with a moisture-tolerant primer.

  3. Step 03

    Coving and drain detailing

    Coves are formed at wall junctions and drains detailed for full hygiene. Sump pans and gullies dressed to fall.

  4. Step 04

    PU screed application

    The polyurethane cementitious screed is mixed on-site and trowel-applied to the specified thickness in one pass.

  5. Step 05

    Seal coat (if specified)

    Where a colour-fast or higher slip rating is required, an aliphatic PU seal coat is applied over the screed.

  6. Step 06

    Audit handover

    Handover pack includes specification, MSDS, cleaning schedule and a written care regime for your auditor.

Cure times

Foot traffic8–12 hours
Wheeled traffic24 hours
Full chemical / wash-down5–7 days

Maintenance guidance

  • Daily: hot wash and CIP-compatible detergent
  • Weekly: rotary scrub with soft brush
  • Steam and pressure wash safe
  • Re-seal every 8–10 years in heavy wash-down zones

Typical applications

  • Kitchens, bakeries, dairies, breweries
  • Meat, fish and poultry processing
  • Cold stores and blast freezers
  • Pharmaceutical wet processes

Frequently asked questions

Yes. PU screed is the default flooring for BRC, SALSA and HACCP audited food environments. Handover pack includes the data your auditor needs.

Yes. The 9 mm system is rated for thermal shock from –40°C to +120°C — steam clean, hot wash and freezer transitions are all handled.

Foot traffic at 8–12 hours. Full chemical cure and wash-down cycle at 5–7 days.

The colour body of the screed carries through the full thickness. Surface staining from turmeric, beetroot or heavy oils is rare and can be scrubbed back.

Yes — we phase by zone or shift, and rapid-cure PU can return a zone to production in 24 hours where the schedule demands.
