Urethane Cement Cross-Reference Matrix
The comparison starts with the floor being specified rather than with the brand name. A smooth self-leveling floor, a heavy troweled mortar, a broadcast texture, and a decorative hybrid are different assemblies even when every manufacturer places them under a urethane-cement or polyurethane-mortar family.
Quick cross-reference: For smooth self-leveling floors, the closest starting comparison is Stonclad UL, Sika Ucrete SL or Sikafloor PurCem SL, and Poly-Crete SL. Ucrete SL+ and Poly-Crete MD form the heavier smooth-build comparison. The broadcast group is Stonshield UTS, Ucrete SLB or SLB+, and Poly-Crete SLB or MDB. For heavy troweled mortar, compare Stonclad UT, UR, or UF with Ucrete UD 200, PurCem TG, and Poly-Crete HF. These are comparison groups, not automatic equivalents.
Comparable Stonhard, Sika, and Sherwin-Williams Systems
| System form or assembly role | Stonhard | Sika | Sherwin-Williams High Performance Flooring | Comparison boundary |
|---|---|---|---|---|
| Smooth, light-build self-leveling floor | Stonclad UL July 2025 PDS: 1/8–3/16 in.; smooth matte finish1 | Sika Ucrete SL (manufacturer data) 80–160 mils / 2–4 mm Sikafloor PurCem SL (manufacturer data) 80–160 mils / 2–4 mm | Poly-Crete SL (manufacturer data) 1/8 in.; self-leveling matte finish | Close comparison by application form. Published thickness bands and optional layers are not identical. |
| Smooth, heavier self-leveling floor | The July 2025 Stonclad UL PDS reaches 3/16 in.; Stonhard’s current webpage lists up to 1/4 in.1 No separately named heavier smooth grade was identified in the reviewed Stonhard sources. | Sika Ucrete SL+ (manufacturer data) 160–250 mils / 4–6.3 mm; smooth self-leveling slurry | Poly-Crete MD (manufacturer data) 3/16–1/4 in.; self-leveling matte finish | Sika and Sherwin-Williams publish distinct heavier self-leveling grades. Stonclad UL overlaps the lower end but is not presented as a separate same-role grade. |
| Textured self-leveling or aggregate-broadcast floor | Stonshield UTS UC-based colored-quartz broadcast system; nominal 1/4 in. in the current reviewed PDS | Sika Ucrete SLB (manufacturer data) 80–160 mils / 2–4 mm Sika Ucrete SLB+ (manufacturer data) 3/16–1/4 in. | Poly-Crete SLB (manufacturer data) 3/16 in. finished system Poly-Crete MDB (manufacturer data) 1/4 in. natural-quartz broadcast system | Functional comparison. The base thickness, broadcast media, topcoat, and finished texture must be compared as a complete assembly. |
| Heavy-duty troweled polyurethane mortar | Stonclad UT Nominal 1/4 in.; textured Stonclad UR 1/8–1/4 in.; trowel applied Stonclad UF 1/4–3/8 in.; textured and unsealed | Sika Ucrete UD 200 and UD 200 SR (manufacturer data) Heavy-duty screed and slip-resistant screed roles Sikafloor PurCem TG (manufacturer data) 1/4–3/8 in.; trowel grade | Poly-Crete HF (manufacturer data) 1/4–3/8 in.; troweled cementitious urethane | Close comparison by heavy-mortar role. Smoothness, texture, sealer, thickness, chemical chart, and temperature conditions remain product-specific. |
| Decorative quartz over a urethane-cement base | Stonshield UTS Polyurethane-mortar base with colored-quartz broadcast and clear sealer | Sika Ucrete UPQ (manufacturer data) Decorative quartz assembly Sikafloor DecoDur Quartz UEF / UEF+ (manufacturer data) Decorative quartz over a PurCem base | Hybri-Flex AQ / AQ One (manufacturer data) Decorative quartz over a Poly-Crete base | Functional comparison of hybrid decorative assemblies. Aggregate, receiver coats, sealers, finished thickness, and UV behavior differ. |
| Decorative flake over a urethane-cement base | No direct Stonhard UC-based flake assembly was identified in the reviewed current U.S. sources. | Sikafloor DecoDur Flake UEF / UEF+ (manufacturer data) Decorative flake assembly over a PurCem base | Hybri-Flex AC / AC One (manufacturer data) Decorative chip over a Poly-Crete base Poly-Crete MDC (manufacturer data) 3/16–1/4 in. decorative chip broadcast | Sika and Sherwin-Williams publish comparable assembly roles. No three-way match is claimed. |
| Cove and vertical-grade urethane mortar | Integral cove options are published for several Stonclad systems. No separate same-role Stonhard product was confirmed in the reviewed sources. | Sika Ucrete WR (manufacturer data) Vertical-grade polyurethane-cement mortar for detailing and coving | Poly-Crete WR (manufacturer data) Trowel-applied vertical and cove component | Partial comparison. Stonhard presents cove primarily as a system option; Sika and Sherwin-Williams publish separately named vertical-grade components. |
1. Stonclad UL source note: Stonhard’s July 2025 product data sheet publishes a 1/8–3/16 in. application range, while its current product webpage publishes 1/8–1/4 in. This matrix preserves both manufacturer-controlled statements rather than treating either upper limit as universal. Confirm the current permitted build with Stonhard for a Stonclad UL specification.
What the Table Does and Does Not Establish
The table is a naming and system-form cross-reference matrix. It reduces catalog confusion without replacing the technical review required for a submittal or approved-equal request.
Comparable Products Are Not Automatically Equivalent Products
Two systems can occupy the same row and still differ in chemistry, total build, primer, aggregate, topcoat, cure conditions, substrate limits, chemical resistance, slip profile, temperature exposure, cleaning requirements, and warranty conditions. “Comparable” means that the products perform a sufficiently similar assembly role to justify reading their current technical documents side by side. “Equivalent” requires the project’s performance criteria and written approval process.
Thickness Must Be Read as a Complete System Build
A product page may state a body-coat thickness while a system sheet states the finished assembly after broadcast and topcoat. For example, a system built from a self-leveling body, aggregate broadcast, receiver coat, and sealer cannot safely be reduced to the thickness of its base material. The table therefore lists manufacturer-published nominal bands rather than reducing them to one universal number. The urethane cement system thickness guide explains how thickness changes with exposure and assembly type.
Surface Description Is Part of the Product Identity
Smooth, matte, textured, broadcast, slip-resistant, decorative quartz, and decorative flake describe different surfaces. A heavy troweled mortar is not the same assembly as a self-leveling slurry with broadcast aggregate, even when both finish at approximately one-quarter inch. Specification review should preserve the required surface, cleanability, drainage, traction, and appearance rather than matching only the nominal thickness.
Current Product Names and Legacy Specifications
Manufacturer acquisitions and naming transitions have left older specifications in circulation. Current names should lead the comparison, with legacy names used only to identify what an older document is referring to.
Sika Currently Publishes Both Ucrete and Sikafloor PurCem Systems
Sika’s current U.S. flooring catalog publishes the Sika Ucrete family and current Sikafloor PurCem systems. They should not be treated as interchangeable names without checking the product-level data. Ucrete SL, SL+, SLB, SLB+, UD 200, UD 200 SR, WR, and newer decorative assemblies sit inside the Ucrete branch. PurCem SL, TG, and PurCem-based UEF assemblies remain separately documented Sika systems.
Sherwin-Williams Changed Many FasTop Names in 2025
Sherwin-Williams’ official cross-reference records a 2025 transition from former FasTop system names into current Poly-Crete and Hybri-Flex names. Examples include FasTop Multi Topfloor SL23 to Poly-Crete SL, FasTop Multi Topfloor SL45 to Poly-Crete MD or MDB depending on the full former system name, FasTop Multi Screed TG69 to Poly-Crete HF, and FasTop Multi Cove Base to Poly-Crete WR. The full legacy name matters because a shortened FasTop reference can point to more than one current assembly. Official 2025 cross-reference.
Stonhard Product Names Stay Inside the Stonhard Delivery Channel
Stonclad and Stonshield names identify Stonhard systems. Craftsman Concrete Floors does not sell or install Stonhard products. Craftsman installs Sika and Sherwin-Williams systems, so the Stonhard column is included as an independent reference. Owners, designers, and contractors can use it to compare an existing Stonhard floor or specification with current products from those manufacturers.
Using the Matrix in a Specification Review
A valid substitution review begins with the installed assembly and the project conditions. Product-family resemblance is only the starting point.
Match the Assembly Before Comparing Published Test Values
First match the application method, minimum and nominal thickness, surface texture, cove or vertical requirement, primer, broadcast media, topcoat, and intended exposure. Compare test values only after those fields align and the published methods and conditions are materially comparable. A higher isolated laboratory value does not establish project suitability when the specimen build or test condition differs.
Check Chemical and Thermal Exposure Against the Exact Product
Chemical resistance must be checked by chemical, concentration, temperature, contact duration, and cleaning procedure. Thermal review must distinguish service temperature from thermal shock while accounting for system thickness. Manufacturer technical review is required when the exposure falls outside a published chart or when several conditions occur together.
Obtain Written Approval Before Treating a Product as an Approved Equal
The specifier, owner, or other party identified in the contract decides whether a proposed alternative satisfies the project requirements. The submittal should identify the original system, proposed system, full layer build, current data sheets, differences, installer qualification, warranty path, and any required test or mockup. The matrix can identify products worth reviewing; it cannot approve the substitution.
Request a Preliminary System Cross-Reference
If you have an existing Stonhard or legacy FasTop specification, send Craftsman the system name and project conditions for a preliminary Sika or Sherwin-Williams cross-reference. The preliminary cross-reference identifies products for technical review; it is not a substitution approval or a claim of equivalence.

Stonhard, Sika, and Sherwin-Williams all publish polyurethane-mortar or cementitious-urethane systems, but their product names do not align one-for-one. The matrix groups current products by application form, published thickness, surface type, and role within the flooring assembly. Products listed in the same row are candidates for technical comparison. They are not automatically equivalent or interchangeable.
The cross-reference uses official U.S. manufacturer sources reviewed August 21, 2026. A project specification, current product data, substrate conditions, chemical exposure, cleaning process, temperature range, and finish requirement control the technical review. Final selection may also require written manufacturer technical confirmation and acceptance by the party designated in the contract.
The urethane cement flooring guide covers system selection, performance, installation, and use conditions for the category as a whole.

Frequently Asked Questions
No. Craftsman does not sell or install Stonhard systems. Stonhard appears in the cross-reference because owners, specifiers, and facility teams frequently need to compare an existing Stonhard floor or specification with the Sika and Sherwin-Williams systems Craftsman installs.
Craftsman installs Sika Ucrete and Sikafloor PurCem systems, along with Sherwin-Williams Poly-Crete and Hybri-Flex systems. The right product depends on the application form, thickness, surface texture, and service conditions of the specific project.
Yes. Craftsman reviews the named Stonhard system and prepares a preliminary cross-reference to comparable Sika or Sherwin-Williams systems. The review identifies candidates for the project’s formal substitution or approved-equal process.
Send the complete existing or legacy product name, the specification section, any submittal package, required thickness and finish, operating temperatures, chemical and cleaning exposures, substrate information, schedule, and warranty requirements.
Comparable means the products perform a sufficiently similar application or assembly role to justify technical review. It does not mean they are chemically identical, interchangeable, or already accepted as approved equals. Current system documents and the project specification control the final determination.
Yes, when the specification permits qualified alternatives. Craftsman can compare appropriate Sika and Sherwin-Williams assemblies against one defined project scope and price each option on the same basis. Final acceptance of any alternative remains with the approving party designated in the contract.
Yes. Decorative quartz and flake systems are compared as complete assemblies, from the urethane cement base through the broadcast and sealer layers. A similar appearance does not establish equivalent construction or performance.
Yes. The complete legacy FasTop system name, checked against Sherwin-Williams’ current cross-reference, identifies the corresponding Poly-Crete or Hybri-Flex system. Shortened FasTop names are not sufficient because similarly named legacy systems can map to different current products.
Yes, when the existing conditions permit it. Craftsman can develop a replacement or addition scope using a Sika or Sherwin-Williams system once the existing assembly, substrate condition, transition details, and any active warranty restrictions have been reviewed. Craftsman does not assume that a new system can be applied directly over an existing Stonhard floor.
Final substitution approval comes from the owner, specifier, design professional, or other party designated in the contract. Where required, written manufacturer technical confirmation also applies. Craftsman prepares the supporting technical cross-reference, product data, and proposed assembly for that decision.
No. Changing manufacturers does not automatically eliminate manufacturer warranty coverage. Exact coverage follows the executed agreement and the manufacturer’s current written terms for the selected system and approved assembly. The customer works through Craftsman, which coordinates warranty administration directly with the selected manufacturer and includes the applicable warranty documents in the contract and closeout records.
Craftsman compares systems from more than one manufacturer while remaining the single contractor responsible for estimating, installation, and field response. Craftsman provides national service coverage and performs installation with Craftsman-employed W-2 crews. When the specification permits alternatives, the owner receives product options from competing manufacturers without splitting installation responsibility among unrelated contractors.
