Arcstruct FL 510 Broadcast and Trowelled Screed System
Heavy-duty aggregate-filled epoxy and polyurethane screed system for process areas, loading bays, bunds and washdown floors, laid as a trowelled screed or as a broadcast build locked in with a seal coat. The aggregate carries impact and point loading and sets the slip profile, and a polyurethane cement grade is used where steam or hot washdown would crack a filled epoxy.

1. Product description
Heavy-duty aggregate-filled epoxy and polyurethane screed system for process areas, loading bays, bunds and washdown floors, laid as a trowelled screed or as a broadcast build with an aggregate scatter and seal coat. The aggregate carries impact and point loading and sets the slip profile, and a polyurethane cement grade is available where thermal shock from steam or hot washdown would crack a filled epoxy. A trowelled screed is also the route to a formed fall where drainage is required. Specified where mechanical abuse, not appearance, decides service life.
2. Features
- Aggregate carries impact and point loading
- Slip profile set by aggregate grade and number of seal coats
- Polyurethane cement grade for thermal shock from steam or hot washdown
- Trowelled screed can form drainage falls
- Coved upstands in the same material for bunded areas
3. Recommended uses
Process areas, loading bays, bunds, plant rooms and washdown floors where mechanical abuse, chemical spillage or thermal shock decides service life.
Substrates. Sound concrete prepared by shot blasting or diamond grinding, with a cut-in edge detail at day joints and drains
4. Typical properties
| Property | Typical value | Method |
|---|---|---|
| Technology | Solvent-free aggregate-filled epoxy screed, with a polyurethane cement grade | Formulation |
| Appearance | Textured, sealed aggregate finish, trowelled or broadcast, in the agreed colour | Visual |
| Binder volume solids, epoxy grades | 98 to 100 per cent, solvent-free; not reported for the polyurethane cement grade | ISO 3233-1 |
| Compressive strength | Typically 50 to 90 MPa, set by grade and aggregate | ASTM C579 or EN 13892-2 |
| Wear resistance, trowelled screed | Typically class AR1 to AR2 by the BCA abrasion test | EN 13892-4 |
| Taber abrasion, seal coat | Typically 30 to 120 mg loss per 1000 cycles, CS17 wheel, 1 kg load | ASTM D4060 |
| Pencil hardness, seal coat | 2H to 4H | ASTM D3363 |
| Slip resistance | Pendulum test value above 36 wet for circulation areas, or R11 to R12 ramp rating for wet process areas, set by aggregate grade and seal coat | BS 7976-2 pendulum, or DIN 51130 ramp test |
| Adhesion to concrete | Failure within the concrete rather than at the bond line | ASTM D7234 |
| Chemical resistance, spot and immersion | Assessed against the named chemical and cleaning agent list for the site, with softening, blistering and colour change reported | ISO 2812-1 and ISO 2812-3 |
Typical values, not a specification. Values for each batch are given on its Certificate of Analysis.
5. Application
| Parameter | Guidance |
|---|---|
| Surface preparation | Sound concrete shot blasted or diamond ground with laitance removed, a cut-in edge detail at day joints and drains, and anchor cuts completed before laying. |
| Slab moisture | Internal relative humidity below 75 per cent to ASTM F2170, screened to ASTM D4263; a moisture-tolerant primer is used where it is higher. |
| Application method | Hand or power trowelled screed, or resin broadcast to excess with aggregate, surplus removed and a seal coat applied. |
| Thickness | Broadcast build 2 to 4 mm; trowelled screed 4 to 9 mm, set by duty and grade. |
| Falls and upstands | Falls to drains formed in the trowelled screed; coved upstands formed from the same material in bunded areas. |
| Slip profile | Set by aggregate grade and the number of seal coats, and confirmed by pendulum or ramp test. |
| Conditions and cure | Substrate at least 3 degrees Celsius above the dew point during application and initial cure. Ambient cure; traffic and chemical service only after the stated cure, which extends in cold conditions. |
Process. Hand or power trowelled screed, or broadcast to excess with a sealer coat. Solvent-free, ambient cure, coved upstands formed from the same material in bunded areas. Anchor cuts and joint detailing completed before laying, and slip profile set by aggregate grade and the number of seal coats
6. Storage and handling
Store the resin, hardener and aggregate components in the original closed containers or sacks under cover, dry and out of direct sun, at 5 to 35 degrees Celsius, keeping aggregate protected from damp. Shelf life is stated on the label and the Certificate of Analysis. Handle and use the product in line with its Safety Data Sheet.
7. Safety and regulatory information
Read the Safety Data Sheet before use. Safety Data Sheets and regulatory declarations are issued by our technical centre against the product and batch supplied, so they are sent on request rather than published. Request a Safety Data Sheet or declaration.
