Hot wash-down, process liquids, traffic and drainage decide the system. PurScreed PC70 is a four-part polyurethane-cement screed installed at 1.5–3 mm.
PU screed is not simply a thicker version of paint. It is a polyurethane-cement system whose suitability depends on the prepared concrete, actual process liquids, cleaning routine, traffic and detailing.
Suitable dry or ambient areas may need an epoxy route instead. Rayson reviews the facility by operating zone so the demanding floor is not under-specified—and the easy floor is not over-specified.
The image, technical priorities and enquiry brief change together. Select the closest condition; the final system still requires project review.
Record the wash temperature, frequency, cleaning chemistry and whether water can drain without ponding. PurScreed PC70 is a PU-cement direction to evaluate—not a blanket answer for every wet floor.
Provide the actual liquid, concentration, temperature, spill frequency, contact time and cleaning method. Suitability must be confirmed against the exposure and current technical data.
Map pallet trucks, mobile vessels, turning zones, fixed equipment and recurring impact points. The system and repair scope should follow where the floor is actually being worked.
Review coves, channels, doorways, plinths, falls and terminations as part of the floor—not as details left until installation. The final build must be confirmed for the actual facility.
The honest specification is often a zoned one: PU-cement for the demanding process area and a confirmed epoxy route for suitable dry or ambient areas.
Preliminary direction only. Confirm substrate, exposure, complete build-up and current product documentation before specification.
These values come from the current PurScreed PC70 product data. Use them for preliminary planning, then verify the complete system in the direct TDS PDF.
PurScreed PC70 is supplied as four pre-weighed components. The parts are combined mechanically in the sequence stated in the current method statement and placed within the published working time.
The current TDS and method statement govern the actual preparation, mixing and application procedure.
Divide the project by operating exposure. This makes the recommendation clearer, more economical and easier to verify.
Review process liquids, cleaning, drainage, traffic and the actual substrate.
Review PC70Suitable packing, production or circulation zones may not require PU-cement.
Review epoxy flooringSpalls, weak edges and defects need a defined repair route before the floor build.
Review concrete repairThe cards below are routes to evaluate. The confirmed project system may require different preparation, primer, detailing or repair after site review.

Self-smoothing epoxy route to evaluate for suitable dry or ambient industrial zones.
Area, photos and the known operating conditions are enough to begin. Rayson will identify the missing facts and provide an initial response within one working day.
PU screed is a polyurethane-cement flooring material. Rayson PurScreed PC70 is a four-part, water-based self-smoothing screed installed at approximately 1.5–3 mm for medium to heavy-duty industrial floors. The final system must be checked against the substrate, operating exposure and current TDS.
They serve different roles. PurScreed PC70 is a polyurethane-cement screed that provides the principal floor thickness. A thin polyurethane coating is generally used as a protective finish within a compatible coating system. Selection should start with the operating conditions rather than the shared “PU” name.
Consider PU-cement when the confirmed wet process, cleaning regime, chemical exposure and industrial duty require that system type. Suitable dry or ambient zones may use an epoxy route. Rayson reviews each zone rather than applying one material throughout the facility.
The published application thickness is approximately 1.5–3 mm by steel trowel. Do not select thickness from a generic rule; confirm the complete build-up against the substrate, duty and current technical documentation.
Published theoretical coverage is approximately 1.8 kg per square metre per millimetre of thickness. Actual consumption varies with surface profile, wastage and project detailing.
It is supplied as a four-part 20.5 kg set: Part A 3 kg, Part B 3 kg, Part C 14 kg and Part D 0.5 kg. All four components must be combined in the sequence stated in the current method statement.
The product information requires mechanically prepared concrete at least 28 days old, with moisture below 5% and substrate pull-off strength above 1.5 N/mm² after preparation. Weak concrete, contamination and unresolved moisture must be addressed before installation.
The actual wash temperature, frequency, cleaning chemistry, drainage and thermal cycle must be disclosed and technically reviewed. The page does not state a universal wash-down temperature limit that is not published in the current product data.
PurScreed PC70 has a published final cure of seven days. Any earlier access or loading plan must be confirmed for the actual temperature, system build, load and current method statement rather than assumed from a generic schedule.
Send the area, substrate and existing floor condition, process liquids, wash-down temperature and frequency, traffic, drains and coves, available shutdown window and clear site photographs. Rayson can begin with incomplete information and identify what must be verified next.
