Master Builders Solutions Ucrete CS
Heavy-duty polyurethane concrete flooring that keeps its colour under UV, aggressive cleaning and hard traffic — engineered for India’s food, beverage and pharma plants.
What is it?
The colour-stable member of the Ucrete polyurethane concrete family from Master Builders Solutions (now part of Sika): a three-layer resin floor — base coat, aggregate broadcast and UV-resistant Ucrete TCCS topcoat — laid at 4 mm (CS10) or 6 mm (CS20).
Where is it used?
Wet and dry process areas in dairies, breweries, beverage bottling halls, food production, pharmaceutical and chemical facilities where the floor must stay presentable, not just survive.
Why use it?
Standard heavy-duty PU floors yellow and stain with time; Ucrete CS holds its shade under UV and daily chemical cleaning while keeping the full Ucrete mechanical backbone of 54 N/mm² compressive strength.
How is it applied?
Installed only by trained, licensed applicators: the base coat is raked and trowelled, aggregate is broadcast to excess, then the colour-stable topcoat is sealed over. The floor returns to service in about 2 hours.
About Master Builders Solutions Ucrete CS
Ucrete has been the reference point for polyurethane concrete flooring in food and beverage plants for decades, but plant managers have long accepted one trade-off: the aromatic chemistry that makes standard Ucrete so tough also lets it amber and discolour under UV light and staining chemicals. Ucrete CS was developed to remove that compromise. It pairs the proven Ucrete base — a water-based polyurethane cement hybrid with graded aggregates — with the Ucrete TCCS encapsulated-resin topcoat, so the finished floor resists yellowing and chemical staining while still shrugging off impact, wear and CIP chemistry. Two build-ups cover most duties: CS10 at 4 mm with a lightly textured R11 finish, and CS20 at 6 mm with a coarser R12 texture for wetter, greasier zones.
Space Arc Engineering supplies and installs Ucrete CS across Delhi NCR and Pan-India as an authorised distributor and applicator. Because Ucrete is a licensed-applicator system, our role goes beyond material supply: we assess the substrate, map plant zones to the right grade and texture, and execute the installation to the manufacturer’s method statement — with the paperwork consultants and food-safety auditors expect.
The technical insight
Polyurethane concrete works because the water-based PU resin co-reacts with cement and graded fillers into a dense, monolithic matrix whose thermal movement is close to that of the concrete beneath it — which is why it tolerates thermal cycling that debonds rigid epoxy screeds. Adhesion tested to EN 1542 exceeds 2.0 N/mm² with failure occurring in the concrete itself, not the bond line. What makes the CS variant different is the top layer: conventional Ucrete finishes use aromatic isocyanate chemistry that gradually ambers under UV, whereas the TCCS topcoat is formulated for colour stability, locking in the broadcast texture and the pigment. The result reads the same on a pull-off test but looks dramatically better after three years of sunlight through roof sheets and nightly chemical washdowns.
Where it is used
- Dairy and cheese processing floors exposed to lactic acid, whey and hot washdowns
- Breweries, distilleries and beverage bottling halls
- Food production and ready-meal facilities with mixed wet and dry zones
- Pharmaceutical manufacturing and packing areas needing low-emission, non-tainting floors
- Chemical processing bays handling staining process fluids
- Cold rooms and freezer stores down to -25 °C (CS20 grade)
- Audit-facing production zones, visitor routes and colour-coded walkways
- Packing halls and corridors linking wet process areas
Key advantages
- Colour-stable TCCS topcoat resists UV yellowing and chemical staining far better than standard aromatic PU floors
- Full Ucrete mechanical backbone: 54 N/mm² compressive and 14 N/mm² flexural strength at 28 days
- Broad resistance to food acids, alkalis, fats, oils and CIP cleaning chemistry
- Back in service in roughly 2 hours, keeping shutdown windows short
- Accepts application on 7-day-old concrete or 3-day-old polymer screed, suiting fast-track programmes
- Does not support bacterial or mould growth and is non-tainting once cured
- Choice of slip grades: lightly textured R11 (CS10) or textured R12 (CS20)
- Certified for food environments: HACCP suitability, Eurofins Indoor Air Comfort Gold (EN 16516) and Halal certification
Limitations & considerations
- Hot spillage is rated to +70 °C (CS10, 4 mm) or +80 °C with light steam cleaning (CS20, 6 mm) — for boiling discharge, heavy steam cleaning or oven surrounds, standard Ucrete DP at 9 mm is the correct system
- Licensed-applicator product only; it cannot be installed by general contractors or in-house maintenance teams
- Application needs +12 °C to +30 °C ambient and substrate temperatures, which takes planning in peak north-Indian summers or inside operating cold stores
- Costs more per square metre than epoxy screeds, so it is hard to justify in dry, light-traffic areas
- The coarser R12 texture holds soil if the cleaning regime is weak — texture must be matched to how the floor will actually be cleaned
Selection & best practice
Substrate quality decides the outcome. Concrete should be captive shot-blasted or planed to remove laitance, with anchor grooves cut at bay edges, drains and doorways to lock the system in. Detail coving, kerbs and drainage falls before the main field goes down — Ucrete floors fail at badly designed details, not in the body of the floor. Hold ambient and substrate temperature between +12 °C and +30 °C, mix full packs only, and work the base coat (BC 4 at 6–8 kg/m² or BC 6 at 10–12 kg/m²) wet-edge to wet-edge. Broadcast the aggregate to excess, sweep back after cure, then seal with TCCS at 0.4–1.2 kg/m² depending on grade. Confirm real consumption on a trial area, since porous or profiled substrates absorb more than theoretical rates.

Industry use cases
Dairy & Cheese
Lactic acid, whey and daily hot washdowns wreck epoxy floors within seasons. CS10 in colour-coded zones keeps hygiene mapping legible through years of scrubbing.
Brewery & Beverage
Sugar acids, caustic CIP returns and constant bottle-line traffic. CS20’s R12 texture keeps wet aisles walkable while the floor stays presentable along brewery tour routes.
Pharmaceuticals
Eurofins Indoor Air Comfort Gold certification and a non-tainting cure suit production and packing suites where emissions and odour transfer are audited.
Ready Meals & Central Kitchens
Fats, oils and washdown cycling call for textured CS20 around prep lines, with lightly textured CS10 in packing zones where trolleys and pallet trucks run.
Cold Chain
CS20 serves freezer stores down to -25 °C, and the 2-hour return to service shortens defrost shutdowns during refurbishment.

How we position Master Builders Solutions Ucrete CS
Ucrete CS sits between appearance and endurance within the Ucrete family. Where discharge runs hotter than +80 °C — cookers, fryers, steam-cleaned kill floors — specify Ucrete DP at 9 mm and use CS in the surrounding visible zones. Ucrete MF gives a smooth, easy-clean surface for medium-duty dry areas, while Ucrete TC topcoats refresh worn Ucrete floors without full replacement. If the area is dry and lightly loaded, an epoxy system such as MasterTop from the same stable, Sikafloor from our Sika range, or Fosroc Nitoflor will do the job at lower cost. Space Arc supplies all of these and can zone-map your plant so each area gets the system it actually needs.
