Sika Ucrete UD 200 SR is a hygienic, heavy-duty polyurethane cement floor screed with very good slip resistance, installed at roughly 1/4 to 1/2 inch as the wearing layer of Sika Ucrete flooring systems. Specs written as Ucrete 200SR or UD200 SR map to Sika Ucrete UD 200 SR. The name survived an ownership change: the current data sheet header still prints formerly Ucrete UD 200 SR, the designation the product carried under BASF and MBCC before Sika closed its acquisition of MBCC Group Construction Systems on May 2, 2023. Every value on this page traces to that data sheet, Version 04.01, June 2026. The manufacturer document governs on any conflict.
The SR grade exists for floors that run wet. Sika’s application guidance warns that excessive finish troweling or rolling degrades the anti-slip characteristics, so the finishing spec protects the texture instead of leaving it to crew discretion. Duty contexts sit at the aggressive end of industrial flooring: food and beverage processing, pharmaceutical manufacturing, chemical and processing facilities, and manufacturing plants running hot washdown or steam cleaning. Craftsman Concrete Floors installs the product as a Sika Certified Installer. In-house W-2 crews mobilize nationwide.

Sika Ucrete UD 200 SR Specification Notes
Four things decide whether Ucrete UD 200 SR is specified correctly. The texture, because slip resistance is the reason the SR grade gets written. The thickness, because the service temperature rating scales with it. The substrate and schedule, because the product tolerates young, damp concrete and can be accelerated into a 12-hour install window. And the name on the spec, because the product has outlived one corporate owner and several shorthand spellings.
Slip Resistance Is What the SR Designation Buys
Wet-area duty is the whole case for the SR grade. Washdown zones, greasy process areas, and wet pack floors put slip-fall exposure at the top of the flooring spec, and Sika documents slip resistance as this product’s defining characteristic alongside impermeability to liquids and resistance to bacterial or mold growth. Field discipline protects that property. The data sheet cautions against excessive finish troweling or rolling because over-finishing dulls the anti-slip texture the grade was specified for. Duty-level depth by facility type lives on the food and beverage flooring pages, and this page stays at the product level.
Thickness Sets the Temperature Rating
A 1/4-inch floor is rated -13°F to 176°F. At 3/8 inch the rating widens to -40°F to 248°F, and a 1/2-inch floor carries -40°F to 266°F with occasional spillage to 302°F, so freezer service and full steam-cleanability both arrive at 3/8 inch. Mechanical values come from the product’s own current PDS rather than family averages. Compressive strength is 7,541 psi at 28 days per ASTM C579, flexural strength is 2,030 psi per ASTM C580, and tensile adhesion exceeds 290 psi with the concrete failing before the bond per ASTM D4541. Kit yield falls as the floor thickens, from 25 square feet per kit at 1/4 inch to 12.5 square feet at 1/2 inch.
Seven-Day Concrete, Damp Slabs, and a 12-Hour Window
Schedule tolerance is this product’s quiet advantage. The PDS supports application onto 7-day-old concrete and 3-day-old polymer screed, lists tolerance of high-moisture substrates, and asks for a minimum 3,625 psi concrete substrate. Unaccelerated, the floor takes traffic in 16 to 24 hours at a 46°F substrate. With Sika Ucrete Accelerator it takes traffic in 4 hours at 50°F inside a 12-hour fast-install window, which is what puts this screed on weekend shutdown and cold-room schedules. Craftsman documents the slab either way, with ASTM F2170 in-situ relative humidity testing and ICRI 310.2 surface profile verification filed in the closeout package, so the warranty record shows exactly what the floor went over.
Formerly Ucrete UD 200 SR, and Still Ucrete on the Sheet
Check the header of the data sheet you are holding. A sheet titled Ucrete UD 200 SR without the Sika prefix is BASF or MBCC vintage, while the current document is Sika Ucrete UD 200 SR, Version 04.01, June 2026, and its own header prints formerly Ucrete UD 200 SR. Sika closed the MBCC acquisition on May 2, 2023 and kept the Ucrete brand, so the renaming is a prefix, not a reformulation, and an older spec reads onto the current SKU. The standard grade without the slip-resistant texture is covered on the Ucrete UD 200 page, the full lineup on the Sika urethane cement hub, and scoping for a named-product install runs through the urethane cement contractor page.

Frequently Asked Questions
Sika Ucrete UD 200 SR is the slip-resistant wearing-layer screed in Sika Ucrete flooring systems, installed at roughly 1/4 to 1/2 inch in food and beverage plants, pharmaceutical facilities, chemical and processing facilities, and manufacturing floors. It is specified where wet processes, hot washdown, and slip-fall exposure govern the flooring decision.
Ucrete UD 200 SR, the same designation under BASF and MBCC ownership before Sika closed its acquisition of MBCC Group Construction Systems on May 2, 2023. The current Sika data sheet still prints formerly Ucrete UD 200 SR in its header, so an older spec naming the product reads onto today’s SKU without substitution.
Sika Ucrete UD 200 SR installs against that spec. Ucrete 200SR and UD200 SR are shorthand spellings of the same designation, and the product kept its name through the 2023 BASF-to-Sika transition. The submittal package records the current naming for the specifier, with the June 2026 PDS as the governing document.
Specify the SR grade wherever the floor runs wet or greasy and slip-fall exposure governs, including washdown zones and wet pack lines. Ucrete UD 200 SR is the slip-resistant grade of the UD 200 wearing screed, and its PDS warns that excessive finish troweling degrades the anti-slip texture, which is the property the SR call-out is buying.
3/8 inch. Per the June 2026 PDS, a 3/8-inch floor is rated -40°F to 248°F and is fully steam-cleanable, while 1/4 inch is limited to -13°F to 176°F. Specify 1/2 inch where service reaches 266°F with occasional spillage up to 302°F.
16 to 24 hours at a 46°F substrate under standard cure. With Sika Ucrete Accelerator, the PDS supports a 12-hour fast-install window with traffic at 4 hours at 50°F. That window is what fits this product to weekend shutdown and cold-room schedules.
Typically no. The PDS lists tolerance of high-moisture substrates and application onto 7-day-old concrete, a tolerance most resin floors cannot claim. Craftsman still runs ASTM F2170 in-situ relative humidity testing and ICRI 310.2 surface profile verification before installation, and both records ship in the closeout package.
Craftsman Concrete Floors installs Sika Ucrete UD 200 SR as a Sika Certified Installer. In-house W-2 crews mobilize nationwide, and scoping, submittals, and scheduling for a named-product install run through the urethane cement contractor page.
