Sika Ucrete UD 200 is a heavy-duty polyurethane cement wearing-layer screed, lightly textured and slip-resistant, rated for service temperatures up to 302°F at full thickness. The current product data sheet carries the line “formerly Ucrete UD 200,” and that single line is the whole naming story. Same product, new prefix. This is the screed BASF and later MBCC Group (Master Builders) sold under the Ucrete name before Sika brought the family into its own catalog. Chemically it is a water-based polyurethane cement hybrid installed at roughly 1/4 inch to 1/2 inch, not a thin-film coating, and its coefficient of thermal expansion of 2.2 x 10^-5 per °F (ASTM C531) sits close to concrete’s, so the floor moves with the slab through thermal cycling instead of shearing away at the bond line.
Craftsman Concrete Floors installs Ucrete UD 200 in food and beverage plants, commercial kitchens, distilleries, and pharmaceutical and chemical processing facilities where hot washdown, aggressive process chemistry, and heavy impact retire thinner systems. Installed thickness governs every UD 200 specification, because thickness sets the service temperature range. 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 build reaches -40°F to 266°F with occasional spillage tolerance to 302°F.

Ucrete UD 200 Performance and Substrate Data
Every number in this section comes from the Sika Ucrete UD 200 Product Data Sheet, Version 03.01, July 2024, which is linked at the bottom of this page. Read the thickness-to-temperature rows before anything else. They decide whether the floor survives its coldest and hottest exposures, and they are the rows most often misread in the specifications we review. Exact values for a specific build always come from the current data sheet.
Service Temperature Is Set by Installed Thickness
Specifying a thin build for a cold room is the most common Ucrete UD 200 spec error. Freezer service to -40°F requires the 3/8 inch build, while the 1/4 inch floor is rated only to -13°F and will not survive deep-freeze duty. Steam-cleanability scales the same way. A 1/4 inch floor tolerates light steam cleaning, and the 3/8 inch and 1/2 inch builds are fully steam-cleanable, which matters wherever sanitation crews run steam under a hot-water protocol.
The Hygiene Profile Is Documented, Not Asserted
Ucrete UD 200 is impermeable to liquids and does not support bacterial or mold growth. From the end of mixing it is non-tainting, which matters around exposed food product. The data sheet backs this with an HACCP test report (I-PE-769-SA-2-RG-06b), a Halal Certification Europe listing, Indoor Air Comfort Gold under EN 16516, and a Bfl-s1 reaction-to-fire class under EN 13501-1. Chemical resistance is defined per individual chemical. Sika Technical Service confirms resistance to a specific exposure before the system is specified, so the actual chemical list from the process floor belongs in the spec package.
Substrate Tolerance and the Installation Window
The screed applies to 7-day-old concrete and 3-day-old polymer screed, and it tolerates the high-moisture substrates that push vapor-impermeable epoxies off the slab. No standing water at placement. The substrate must be structurally sound, minimum 3,625 psi compressive and 217 psi tensile, clean and free of laitance. Construction joints and static cracks are pre-treated with Sikadur or Sikafloor resins before the wearing layer goes down. Craftsman documents the slab before material ships, moisture per ASTM F2170 and surface profile per ICRI 310.2, so the substrate record sits in the closeout package instead of in dispute after the pour.
Mechanical Values and Return to Traffic
Compressive strength is 7,977 psi per ASTM C579, flexural strength 2,030 psi per ASTM C580, and tensile adhesion exceeds 290 psi per ASTM D4541 with failure in the concrete, meaning the slab lets go before the bond does. Coverage runs 22 square feet per kit at 1/4 inch, 16 at 3/8 inch, and 11 at 1/2 inch. Return to traffic is under 24 hours at a 46°F substrate. With Sika Ucrete Accelerator, that drops to about 4 hours at 50°F, which turns a weekend shutdown into an overnight window on a phased pour.

Specifying and Installing Sika Ucrete UD 200
Formerly Ucrete UD 200 — the Name in the Document Header
Sika’s own documents carry the naming story in their headers: the product data sheet and safety data sheets read “formerly Ucrete UD 200.” Ucrete originated under BASF and passed to MBCC Group, the Master Builders construction chemicals business, and Sika closed the MBCC acquisition on May 2, 2023. The product did not change. A specification that reads Ucrete UD200 with no manufacturer prefix, or that names BASF or Master Builders as the source, installs today as Sika Ucrete UD 200, and the full brand lineage is on the BASF Ucrete page.
Where Ucrete UD 200 Sits in the Sika Line
Ucrete UD 200 is the heavy-duty, thick-build member of the Sika Ucrete family, installed at 1/4 to 1/2 inch above the film builds of the self-leveling slurry systems. Ucrete SL and Ucrete SLB run 80 to 160 mils on Ucrete HS24 NA, and Ucrete SL+ builds on Ucrete HS22 NA. UD 200 carries the ratings that come only with thickness, including -40°F freezer rooms at 3/8 inch and occasional 302°F spillage at 1/2 inch. Ucrete UD 200 SR is the slip-resistant grade of the same screed. The full lineup lives on the Sika Ucrete page.
Sika Certified Installation Nationwide
Craftsman Concrete Floors installs Sika Ucrete UD 200 as a Sika Certified Installer. In-house W-2 crews mobilize nationwide. Zone-by-zone phasing keeps occupied plants in production while the floor goes down, with cure windows short enough to hand zones back between shifts. Install scoping and scheduling are covered on the urethane cement contractor page.

Frequently Asked Questions
Sika Ucrete UD 200 is specified for heavy-duty processing floors in food and beverage plants, commercial kitchens, distilleries, and pharmaceutical and chemical processing facilities. It carries the chemical, impact, and temperature duty that retires thin-film systems, installed at 1/4 to 1/2 inch as a lightly textured, slip-resistant wearing layer.
Ucrete UD 200, without the Sika prefix, under BASF and later MBCC Group (Master Builders). Sika closed the MBCC acquisition on May 2, 2023, and the current data sheet still reads “formerly Ucrete UD 200.” A spec written against BASF or Master Builders Ucrete UD200 installs today as Sika Ucrete UD 200, the same product under the current name.
3/8 inch minimum. A 3/8 inch UD 200 floor is rated to -40°F and is fully steam-cleanable, while the 1/4 inch build is rated only to -13°F and is not suitable for deep-freeze duty. Thickness, not chemistry, carries the cold rating on this product.
-13°F to 176°F at 1/4 inch, -40°F to 248°F at 3/8 inch, and -40°F to 266°F at 1/2 inch with occasional spillage tolerance to 302°F. Installed thickness sets the range, so the specification starts from the coldest and hottest exposures the floor will see.
Under 24 hours at a 46°F substrate temperature, per the July 2024 PDS. Sika Ucrete Accelerator cuts that to about 4 hours at 50°F. Short cure windows are what let UD 200 zones phase around production instead of forcing a plant shutdown.
Ucrete UD 200 SR is the slip-resistant grade of the UD 200 screed, specified for wet-process zones that need a more aggressive texture than the standard finish. Its values trace to its own data sheet, and the Ucrete UD 200 SR page carries them alongside the current Sika documentation.
$4-17/sqft installed depending on project size, system thickness, and substrate condition. Project size is the dominant driver, which is why the band is wide. The urethane cement cost page carries the full size-band table and what moves a project within it.
