Sherwin-Williams urethane cement ships under two family names: Poly-Crete, the cementitious urethane line, and Hybri-Flex, the hybrid systems built on a cementitious urethane base coat. Both families came to Sherwin-Williams in the July 1, 2022 acquisition of Dur-A-Flex. The product names survived the deal. A spec written around Dur-A-Flex urethane cement is still a live spec, now answered by the Sherwin-Williams High Performance Flooring division. This page is the index to that line, not the data sheet for any product in it. Poly-Crete SL, MD, MDB, SLB, HF, and Hybri-Flex EC each have their own page carrying the full build-up, moisture behavior, topcoat options, and a link to the current manufacturer document.
Start from what the spec says. A current Poly-Crete or Hybri-Flex name routes straight to its product page below, and a General Polymers FasTop code routes through the FasTop legacy page, where every code maps to exactly one current product. Install intent is its own path. Craftsman Concrete Floors is an authorized Sherwin-Williams High Performance Flooring installer, and scoping for any Sherwin-Williams-specified floor starts on the urethane cement contractor page.

The Poly-Crete and Hybri-Flex Product Pages
One product, one page is the rule for the whole tree. Each page below owns its product’s codes, its FasTop history where one exists, its thickness and moisture limits, and its current Sherwin-Williams document. This hub deliberately carries none of that depth. The one-line entries here exist to hand a spec reader to the right page fast, because the most common failure on a brand search is landing one level too high and reading the wrong grade’s numbers.
Self-Leveling Grades — Poly-Crete SL and Poly-Crete MD
Poly-Crete SL, formerly General Polymers FasTop Multi Topfloor SL23, is the line’s self-leveling grade. Poly-Crete MD, formerly General Polymers FasTop Multi Topfloor SL45, is the self-priming matte self-leveler and the volume workhorse of the line. Two distinct FasTop SL45 codes existed and route to two different current products, so the Poly-Crete MD page settles that mapping before a spec reader chases the wrong one. Full build-up and moisture behavior are page-level content on the Poly-Crete SL page. Neither answer lives here.
Poly-Crete SLB and MDB Are the Broadcast Systems
Broadcast texture is what separates these two grades from their self-leveling siblings. Poly-Crete SLB, formerly General Polymers FasTop Topfloor SL13, takes a broadcast and a choice of seal coats; the Poly-Crete SLB page covers the seal-coat range and the SLB-UV question. Poly-Crete MDB, formerly General Polymers FasTop Topfloor SL57, is the broadcast grade whose finish properties follow its topcoat, and the Poly-Crete MDB page carries the TF Plus topcoat story. Slip texture and cure windows are page-level answers.
The Heavy-Duty and Hybrid Ends of the Line
Poly-Crete HF, formerly General Polymers FasTop Multi Screed TG69, is the trowel-applied heavy-duty grade, and thickness questions belong on the Poly-Crete HF page. Hybri-Flex EC is the structural outlier in the tree, a hybrid system on a cementitious urethane base coat rather than a pure urethane cement, with no single FasTop predecessor of its own. The Hybri-Flex EC page explains the hybrid build and the topcoat that finishes it. If a spec names another Hybri-Flex variant, start there anyway. The EC page frames the family.

From Dur-A-Flex and FasTop to High Performance Flooring
Two corporate events sit behind every naming question on this brand’s specs, and installer sites conflate them routinely even though they are three full years apart. The difference matters because submittals and warranty paperwork follow whichever entity currently publishes the governing documents. The dates below are the whole story. The per-code mappings live on the product pages and the FasTop legacy page, never here.
July 1, 2022 — the Dur-A-Flex Acquisition
Sherwin-Williams acquired Dur-A-Flex effective July 1, 2022. The Poly-Crete and Hybri-Flex names were retained, so nothing in a Dur-A-Flex-era spec needs translation at the product level. What changed is the entity behind the documents. Data sheets, submittal packages, and warranty paperwork now issue from Sherwin-Williams, and the current versions are linked from each product page rather than from archived Dur-A-Flex files. A 2019 Dur-A-Flex submittal is a historical document; the floor gets built to the current one.
The 2025 High Performance Flooring Consolidation
The High Performance Flooring branding arrived in 2025, three years after the acquisition, as its own event. That consolidation folded Dur-A-Flex into the Sherwin-Williams High Performance Flooring division and moved the General Polymers FasTop urethane cement line into Poly-Crete; the decorative FasTop flake codes went to the Hybri-Flex family instead. Spec readers hit this distinction constantly. It is also why the credential reads authorized Sherwin-Williams High Performance Flooring installer, by the full program name, rather than any predecessor-brand phrasing.
FasTop Specs Route One Code to One Page
Every General Polymers FasTop code maps to exactly one current product, and the FasTop legacy page is the switchboard holding the full routing table for the whole line. Bring the complete legacy name from the spec. Truncated codes are where routing errors start. From there, each Poly-Crete page owns its former names and carries them in full. The FasTop family page also answers the discontinuation question directly, along with the misspellings, FastTop among them, that show up in older construction documents.
Who Installs Sherwin-Williams Urethane Cement
The Sherwin-Williams Urethane Cement Credential, by Program Name
Authorized Sherwin-Williams High Performance Flooring installer is the full program name, and it is the form to verify. Craftsman Concrete Floors holds that authorization and installs the Poly-Crete and Hybri-Flex urethane cement flooring families across food processing, commercial kitchen, brewery, bottling, and cold storage work. A contractor offering only generic authorized installer wording, with no program name attached, is worth one call to the Sherwin-Williams High Performance Flooring regional rep before award. The credential travels with the manufacturer warranty paperwork. Verification is cheap insurance.
Install Intent Starts on the Contractor Page
Scoping, pricing, and approved-equal questions live on the urethane cement contractor page, which owns install intent for every brand Craftsman installs. This hub and the product pages stay reference-first by design. What Craftsman brings to a Sherwin-Williams-specified project is the same on every site. In-house W-2 crews mobilize nationwide. Pre-install moisture and substrate testing runs to ASTM F2170 and ICRI 310.2, the closeout package ships audit-ready, and phased installation around live production gets planned at scoping.

Frequently Asked Questions
Sherwin-Williams urethane cement is the Poly-Crete and Hybri-Flex product families, sold through the Sherwin-Williams High Performance Flooring division since the July 1, 2022 acquisition of Dur-A-Flex. Poly-Crete is the pure cementitious urethane line; Hybri-Flex builds hybrid systems on a cementitious urethane base coat. Each product has its own page here.
Dur-A-Flex was acquired by Sherwin-Williams effective July 1, 2022, and the Poly-Crete and Hybri-Flex product names were retained. A Dur-A-Flex urethane cement spec is still valid at the product level; the documents behind it now issue from the Sherwin-Williams High Performance Flooring division instead. Current data sheets are linked from each product page.
Yes. Polycrete is a common one-word rendering of Poly-Crete, the hyphenated name Sherwin-Williams uses on its own documents. The family covers Poly-Crete SL, MD, MDB, SLB, and HF, and each grade has a dedicated page on this site with its former FasTop name mapped in full.
Start on the FasTop legacy page. It holds the full code-to-product routing table. Every FasTop code maps to exactly one current product, and bringing the complete legacy name from the spec matters because truncated codes are ambiguous on their face. The destination product page then carries the mapping and the current Sherwin-Williams document.
Poly-Crete systems are urethane cement through the full build. Hybri-Flex systems put resinous topcoat layers over a cementitious urethane base coat, trading the pure system’s simplicity for finish options the base mortar cannot provide on its own. The Hybri-Flex EC page frames the hybrid family; the five Poly-Crete pages cover the pure line grade by grade.
Sherwin-Williams High Performance Flooring is the division carrying the company’s resin flooring lines, including the Poly-Crete and Hybri-Flex urethane cement families. The branding arrived in 2025, three years after the Dur-A-Flex acquisition, and the same consolidation folded the General Polymers FasTop urethane cement line into the current Poly-Crete family. It is also the program name on the credential.
Craftsman Concrete Floors installs the Poly-Crete and Hybri-Flex families as an authorized Sherwin-Williams High Performance Flooring installer, with in-house W-2 crews that mobilize nationwide. Scoping starts on the urethane cement contractor page, which owns install intent for every brand Craftsman installs, including specs that still carry legacy FasTop names.
Ask for the credential by its full program name and confirm it with the Sherwin-Williams High Performance Flooring regional rep, who maintains the authorized installer list. Generic authorized installer wording with no program name attached is the tell worth checking before award. Warranty paperwork follows the authorization at closeout.
