PU flooring in Singapore — coatings and screeds, separated properly
'PU flooring' covers two very different things. Polyurethane coatings are UV-stable, abrasion-resistant finish coats — the right choice for exposed decks and colour-critical floors. PU-cement screeds are thick, trowel-applied floors built for hot wash-down, steam and organic acids in food and chemical plants. Rayson manufactures both — the UraForce coating family and the PurScreed PC70 screed — and will tell you plainly which your project actually needs.
PU coating vs PU-cement screed
| PU coatings (UraForce) | PU-cement screed (PurScreed) | |
|---|---|---|
| What it is | Resin finish coats, roller-applied | Resin + cement + aggregate, trowel-applied |
| Thickness | Thin film finish | 1.5–3 mm and up |
| Signature strengths | UV stability, colour retention, abrasion resistance, flexibility | Thermal shock, hot wash-down, organic acids, impact |
| Typical homes | Exposed decks, car parks, retail, sports, sealed epoxy systems | F&B production, commercial kitchens, chemical plants |
| System role | Finish over primer/body coat | The floor itself, coved at junctions |
| Rayson products | WB52, WB58, WB60, SB72, SB65, HY15 | PurScreed PC70 |
The UraForce polyurethane range
Water-based aliphatic finishes — WB52, WB58 and WB60 — give UV-stable, low-odour top coats for occupied buildings and colour-critical floors. Solvent-based finishes — SB72 and SB65 — maximise film performance where ventilation allows. HY15 is the one-component hybrid for fast roller-applied refresh work.
PurScreed PC70 — the heavy-duty screed
PurScreed PC70 is a four-part, water-based polyurethane-cement screed installed at 1.5–3 mm by steel trowel. It exists for the conditions that destroy ordinary resin floors: steam cleaning, hot oil and fat, organic acids and constant wet traffic in food & beverage and chemical processing facilities.
Buying tip: if a quote says "PU flooring" for your F&B
kitchen, ask whether it is a PU coating or a PU-cement screed.
The wrong one fails at the first steam clean — and the price difference will
tell you which is being offered.

Most PU coatings ride on an epoxy foundation: PrimeBond E20 primer, an epoxy body coat where build is needed, then the UraForce finish. For exteriors, see waterproofing & protective coatings; for the epoxy layers underneath, see epoxy flooring in Singapore.

What is the difference between PU flooring and PU-cement (PU screed)?
They are different materials doing different jobs. PU flooring usually means polyurethane resin coatings — UV-stable, abrasion-resistant finish coats. PU-cement (polyurethane screed) blends PU resin with cement and aggregate into a thick trowel-applied floor that shrugs off hot wash-down, steam and organic acids. Suppliers often blur the two; specifying the wrong one is expensive.
When do I need a PU-cement screed instead of epoxy?
When the floor faces thermal shock (hot water, steam cleaning), aggressive organic acids and fats, or heavy impact — the classic food-and-beverage and chemical-processing conditions. Under those loads standard epoxy fatigues; PU-cement is engineered for them.
Is PU flooring UV-stable for outdoor use in Singapore?
Aliphatic polyurethanes hold colour and gloss under UV, which is why PU is the standard finish for exposed decks, car park top decks and any sun-exposed floor. Aromatic PUs and standard epoxies yellow — check which type you are being offered.
Can PU topcoats be applied over epoxy?
Yes — an epoxy body coat sealed with a PU finish is one of the most common industrial systems: epoxy provides economical build and chemical resistance, PU provides the tough, UV-stable wearing surface. Recoat windows between the layers must be respected.
Are water-based PU floor finishes any good?
Modern water-based aliphatic PUs like Rayson UraForce WB52 and WB60 deliver genuine UV stability and abrasion resistance with low odour — ideal for occupied buildings. Solvent-based versions like SB72 remain the pick where maximum film performance is needed and ventilation allows.
How soon can an F&B floor return to production after a PU screed?
PU-cement screeds are chosen partly for fast return to service, but real timings depend on thickness, temperature and the hygiene regime. Share your shutdown window with our technical team and we will map the programme honestly before you commit.
