Sika Ucrete MF is a smooth, heavy-duty polyurethane cement floor screed applied at approximately 4 to 6 mm, about 3/16 to 1/4 inch, as the wearing layer in dry-process areas. If your specification predates May 2023, it may read Ucrete MF under BASF or Master Builders Solutions branding; Sika’s acquisition of MBCC Group closed May 2, 2023, and the product entered the Sika catalog with its code intact — the current name is Sika Ucrete MF. The system is the smooth-finish member of the Ucrete family. Chemical and processing facilities, clean rooms, dry packing lines, storage areas, and warehouses specify it where a flat, cleanable, chemical-resistant surface matters more than the wet-condition grip of the textured Ucrete wearing layers.
Current Sika documentation puts the mechanical case in three numbers: 50 N/mm² compressive strength and 20 N/mm² flexural strength per EN 13892-2, with tensile adhesion above 2.0 N/mm² that fails in the concrete rather than at the bond line (EN 1542). The chemistry is a water-based polyurethane cement hybrid, impermeable to liquids and non-tainting from the end of mixing, with a service temperature of -15°C to +70°C, roughly 5°F to 158°F. Sika’s US product page notes the formulation has run in industrial service for more than 40 years.

Where Ucrete MF Fits and How It Installs
Ucrete MF answers a specific selection question inside the Ucrete family. Most of the line exists for wet duty; this screed exists for the rooms that stay dry. The profile below covers the finish logic, the temperature and resistance band, the substrate and cure behavior that drive scheduling, and the naming history a spec reader needs when an older document is on the desk.
Smooth Finish, Dry-Process Duty
A smooth wearing surface is what separates Ucrete MF from the textured Ucrete screeds, and it defines where the system belongs. Clean rooms, dry packing lines, laboratories, warehouses, and dry chemical processing areas get a flat profile that cleans fast and resists heavy abrasion under foot and forklift traffic. The finish carries a Class R 10 rating per DIN 51130 with a wet pendulum test value of 35, which is grip for incidental moisture, not washdown duty. Where a floor sees standing liquid, hot washdown, or heavy slip-fall exposure, a textured Ucrete wearing layer is the correct specification instead.
Service Band — 5°F to 158°F With Aggressive-Chemical Resistance
Sika’s current product data sheet, Version 03.02, rates Ucrete MF from -15°C to +70°C, about 5°F to 158°F. The band is set for ambient and dry-process duty. Freezer rooms and sustained high-temperature washdown belong to the heavier textured Ucrete systems, which carry the family’s wider ranges. Within its band the screed is impermeable to liquids and holds very good resistance to aggressive chemicals and heavy abrasion, and the certificate list on the PDS covers HACCP, Halal (HCE), and Indoor Air Comfort Gold low-emission testing per EN 16516, which is why the dry zones of food and pharmaceutical plants specify it.
7-Day Concrete and a 4-Hour Accelerated Return to Traffic
Substrate tolerance is the scheduling story. Ucrete MF places on concrete as young as 7 days old, and on green or damp concrete with no standing water, against the PDS minimum of 1.5 N/mm² surface tensile strength. Return to traffic runs under 24 hours at +8°C (46°F); with Sika Ucrete Accelerator the PDS puts it near 4 hours at +15°C (59°F), which is what makes shutdown-window placement practical. Craftsman crews verify substrate moisture and surface profile before placement, and the readings go into the project file.
If the Spec Reads BASF Ucrete MF
Older construction documents cite Ucrete MF under BASF or Master Builders Solutions branding, and the mapping is one-to-one. Sika closed its acquisition of MBCC Group on May 2, 2023, and its US product-name-change document lists Ucrete MF becoming Sika Ucrete MF with the code unchanged. The product was not consolidated into another system and was not discontinued; only the brand prefix moved. A spec reading the old name installs as the current product without a substitution request. Craftsman Concrete Floors is a Sika Certified Installer, and in-house W-2 crews mobilize nationwide; the urethane cement contractor page covers engagement from spec review through project closeout.

Frequently Asked Questions
Sika Ucrete MF is a smooth polyurethane cement screed for dry-process areas, meaning chemical and processing facilities, clean rooms, dry packing lines, storage, and warehouses. The smooth finish suits rooms where a flat, easy-to-clean floor matters more than wet-condition grip. Areas with standing liquid or washdown duty take a textured Ucrete wearing layer instead.
Ucrete MF, under BASF and then Master Builders Solutions branding. Sika’s acquisition of MBCC Group closed May 2, 2023, and Sika’s US name-change document maps Ucrete MF to Sika Ucrete MF one-to-one with the code unchanged. Old specifications citing the BASF-era name install as the current product.
Approximately 4 to 6 mm, about 3/16 to 1/4 inch, applied as a wearing layer. The US product page credits the system with excellent impact resistance at the full 1/4-inch build. Heavier duty classes in the Ucrete family come from the textured screeds rather than from building MF thicker.
Wet rooms disqualify it: washdown bays, drains-and-hoses sanitation zones, and any floor with real slip-fall exposure call for a textured, slip-resistant Ucrete wearing layer. Temperature draws the second line, since the current PDS rates Ucrete MF from -15°C to +70°C, about 5°F to 158°F. Duty outside that band, freezer rooms included, belongs to heavier members of the Ucrete family.
Ucrete MF projects price at $4-17/sqft installed depending on project size, system thickness, and substrate condition. The band is wide because project size dominates the unit price. Craftsman’s urethane cement cost page carries the size-banded breakdown behind that range.
Under 24 hours at +8°C (46°F), per the current PDS. Sika Ucrete Accelerator pulls return to traffic down to roughly 4 hours at +15°C (59°F). Craftsman schedules zone-by-zone work against those cure figures, so a production area can release a zone at night and take it back the same shift.
Yes. The PDS accepts concrete as young as 7 days old and green or damp concrete with no standing water, against a minimum surface tensile strength of 1.5 N/mm². Craftsman still runs pre-install moisture and substrate testing on every placement; damp tolerance is a material property, not a reason to skip moisture verification.
