Where Specs and Data Live Now: Each destination page above carries the current Sherwin-Williams High Performance Flooring documentation for its system; per-system thickness, finish, and mechanical values live there, not on this page

FasTop was the General Polymers urethane cement line under Sherwin-Williams, and every FasTop code maps to a system that installs today. In the 2025 Sherwin-Williams High Performance Flooring branding transition, the line folded into Poly-Crete: a specification that reads FasTop Topfloor SL13 installs as Poly-Crete SLB, and each remaining code follows the same one-to-one mapping shown in the table below. Nothing in a Sherwin-Williams FasTop spec is orphaned. The self-levelers, broadcasts, and screeds those codes describe continue as current Poly-Crete systems, and this page exists to route a legacy FasTop code to the right current system in a single lookup.

Craftsman Concrete Floors installs the current Poly-Crete systems against legacy FasTop specifications. In-house W-2 crews mobilize nationwide, and the company holds the authorized Sherwin-Williams High Performance Flooring installer credential. The original FasTop systems served commercial kitchens, food processing plants, breweries, and industrial washdown areas; their current equivalents serve the same duty as urethane cement flooring, with working documentation carried on each product’s own page. Phased installation around active operations is standard on replacement work. Weekend shutdown windows are a standard scheduling option.

Matching a Legacy FasTop Spec to the Current Poly-Crete System

The FasTop name outlives its place in the catalog. Old specifications still call for it, and floors installed under it are still in service. The question what is FasTop called now has a one-word brand answer (Poly-Crete) and a per-code answer, because each FasTop system mapped to a specific current product rather than to the family as a whole. The table above routes every full code name to its current system page; the sections below cover the lineage and the substitution path.

From General Polymers FasTop to Sherwin-Williams Poly-Crete

General Polymers FasTop was the urethane cement line in the Sherwin-Williams resinous flooring catalog until 2025. Sherwin-Williams acquired Dur-A-Flex on July 1, 2022, and the separate 2025 branding transition consolidated its resinous flooring under Sherwin-Williams High Performance Flooring — the Dur-A-Flex Poly-Crete name was retained, and FasTop folded into it. Each FasTop code mapped to one current product. The chemistry did not change category: a FasTop urethane cement spec still describes a cementitious urethane mortar, now documented under its current Poly-Crete or Hybri-Flex name.

A FasTop Topfloor SL13 Spec Installs Today as Poly-Crete SLB

This is a renaming, not a competitive substitution. When a construction document calls for FasTop Topfloor SL13, the installable system today is Poly-Crete SLB; FasTop Multi Screed TG69 resolves to Poly-Crete HF the same way. Craftsman confirms each mapping at pre-bid review against current Sherwin-Williams documentation and records the substitution in the spec file, so the closeout package names the product actually installed. Spec engineers reissuing an old General Polymers section get current data sheets behind every code.

Where FasTop Systems Were Specified

Cove base called out on a FasTop spec installs today as the integral cove detail on the mapped Poly-Crete system, formed in the same mortar pour as the floor rather than applied as a separate component. The integral cove base page covers the detail itself. Accessory and component products named in legacy FasTop documents are confirmed against current Sherwin-Williams High Performance Flooring naming at spec review; not every legacy accessory carries a published current equivalent, and none gets assumed at the desk.

Cove Base and Accessories on a Sherwin-Williams FasTop Spec

A FasTop flooring section in an older construction document almost always points at washdown duty, where floors take hot-water cleaning and chemical sanitation around food and beverage production. Those are urethane cement flooring applications. Per-system operational values live on the destination datasheet pages, where each current equivalent carries its Sherwin-Williams documentation, thickness and finish included, rather than being restated here. USDA, FDA, and HACCP program requirements that drove an original FasTop specification are addressed the same way on the mapped current system.

Frequently Asked Questions

No. The FasTop line folded into Poly-Crete during the 2025 Sherwin-Williams High Performance Flooring branding transition, and every FasTop code maps to a current system that remains in production. A floor specified as FasTop in an older document installs today under its Poly-Crete name.

Poly-Crete is the current name for the FasTop urethane cement systems, with one current product per legacy code: FasTop Topfloor SL13 is now Poly-Crete SLB, FasTop Multi Topfloor SL23 is Poly-Crete SL, FasTop Multi Topfloor SL45 is Poly-Crete MD, FasTop Topfloor SL57 is Poly-Crete MDB, and FasTop Multi Screed TG69 is Poly-Crete HF. FasTop Deco Flake SL45 continues as Hybri-Flex AC in the decorative hybrid family.

The current system for that callout is Poly-Crete SLB, the slip-resistant broadcast self-leveler role under Sherwin-Williams High Performance Flooring naming. Because Poly-Crete SLB carries the same manufacturer lineage as the code it replaced, submittals and warranty registration run through Sherwin-Williams exactly as the original specification intended.

FasTop Multi Screed TG69 held the trowel-applied screed role in the line. That role belongs to Poly-Crete HF today, and current thickness and performance documentation lives on the Poly-Crete HF datasheet page rather than here.

General Polymers, a Sherwin-Williams brand, sold FasTop as its urethane cement line. The 2025 consolidation under Sherwin-Williams High Performance Flooring retired the General Polymers FasTop naming and moved each system into Poly-Crete — a name Sherwin-Williams kept from its July 1, 2022 acquisition of Dur-A-Flex.

Yes. Repair and extension work matches the existing FasTop floor to its current Poly-Crete equivalent and ties new material into the old pour after substrate verification — in-situ relative humidity testing per ASTM F2170 and surface profiling per ICRI 310.2 come before installation is scheduled.

Craftsman Concrete Floors is an authorized Sherwin-Williams High Performance Flooring installer, with the authorization covering current Poly-Crete and Hybri-Flex systems and legacy FasTop specifications. Verification is available through Sherwin-Williams High Performance Flooring directly, and closeout packages include manufacturer warranty registration.

FasTop cove base installs on a current project as the integral cove detail of the mapped Poly-Crete system — part of the floor pour itself, which eliminates the wall-floor joint that USDA and FDA inspection protocols scrutinize. Accessory product names from legacy FasTop documents are matched to current naming at spec review, since published mappings exist per system but not for every accessory SKU.
