Technical Data

Everything ANVIL can substantiate about the coating, with the document it came from. Anything not on this page is not something we are prepared to state yet.

Typical properties

Every row above is transcribed from the manufacturer’s own data sheets — Duromar’s, one per product. Values that are not on that sheet are not in this table.

Coverage

The data sheet gives a formula rather than a fixed rate. Divide the desired thickness in mils into 1604:

Duromar caveats the figure directly: coverage is affected by the condition and type of substrate and by the ability of the applicator to hold a consistent thickness. That caveat is the substantiation for the overage built into every kit — theoretical coverage is a ceiling, not a plan. Size your floor.

Specified system build

The system as the data sheets specify it: clean and profile the concrete to ASTM D 4258 and D 4259, until it has the texture of 60–80 grit sandpaper; Anvil Prime at 5 mil nominal, one coat, left at least four hours; premix Part A and Part B separately, combine at 2:1 by volume, 2.4:1 by weight and mix two to three minutes with a Jiffy mixer without plunging it, which folds in air; apply Anvil Coat-AE and broadcast into it wet to refusal; cure firm, sweep off the excess, scrape flat and patch; topcoat with Anvil Coat ClearTop at 12 mil nominal by squeegee and back-roll, observing its 6–12 hours window between coats; then 5 days to full service.

The broadcast media in that specification is 20/40 mesh silica sand. ANVIL broadcasts decorative vinyl flake by the same method. The full build, step by step.

Storage — a requirement, not advice

Storage temperature is 50–110°F — that is what a sealed pail survives, not what you should be working with. Bring the kit to 60–80°F for 48 hours before use before you open it. Material at the top of the storage range goes off in the bucket faster than you can spread it. Shelf life is 12 months properly stored and sealed. A kit that spends a northern winter in an unheated garage has been outside the specified range, and that is worth planning around: if the kit will arrive before you can coat, store it inside the house.

Health and safety

The manufacturer safety data sheets for the primer and the topcoat arrived in September 2026, and this section is what they say rather than a summary of what we would prefer them to say. Full sheets for every component ship with your order, and we will send them before you buy if you would rather read them first — ask.

The topcoat is a respiratory sensitizer, and this is the one that matters

The clear topcoat carries a Category 1 respiratory sensitizer classification with the signal word Danger, and the hazard-determining components named on the sheet are the isocyanates that make a polyaspartic a polyaspartic. That is inherent to the chemistry, not a fault in this particular product, and it is the trade that comes with a coating that returns to service in hours and never ambers.

Sensitization is not an irritation that fades. Once somebody is sensitized they react to traces of it afterwards, permanently. Most people never develop it, and the ones who do were generally working without protection in a room that was not moving air. So: a half-face respirator with organic-vapor cartridges, on every person in the garage, from the first pail opened until the coating has gone off. A paper dust mask does nothing about vapor.

A professional crew wears one for this without discussion. It is worth stating plainly here because nobody is handing a homeowner the equipment, and a garage with the door half down is a much smaller room than the plant floors these coatings were written for. What to wear has the rest of the list, and anyone with asthma or an existing respiratory condition should have somebody else lay it.

The carcinogen classification is silica, and the exposure route is dust

Two of the sheets carry a Category 1A carcinogen classification, H350. Both trace to one line in the composition table: silicon dioxide, CAS 14808-60-7, which is crystalline silica. It is classified as a carcinogen as respirable dust — that is the entire basis of the listing, and it is why the same classification appears on a great many fillers, mortars and sealants that nobody thinks twice about.

Bound in a liquid resin there is nothing respirable to inhale. The place somebody doing this job actually meets respirable silica is grinding the slab, before a single pail is opened — which is why preparation specifies a grinder with a HEPA extractor rather than treating dust control as an optional extra. The same applies at the other end: do not grind or sand the cured floor without extraction.

Transport

Every component of the standard kit ships unregulated. Primer and topcoat, both parts of each, are recorded on their sheets as not regulated by USDOT under 49 CFR Parts 171–180: no hazard class, no UN number, no packing group. That is a real answer rather than an absence of one, and it is why freight here is a flat charge rather than a hazmat surcharge.

What is still outstanding

Publishing the gaps is the same job as publishing the table. These are open, and each is a request in with the supplier or a test ANVIL has not run.

• Safety data sheet for the pigmented body coat. We hold sheets for the primer and the clear topcoat. The body coat is the layer somebody spends longest standing over, and its own sheet is the one still to arrive. Until it does, the Proposition 65 entry above is carried from the coating this line replaced and is labelled provisional in our own records rather than presented as settled.
• Clear topcoat data sheet. The safety sheet has arrived; the technical one has not. The topcoat is the wear surface, so its absence is still the largest hole in the table above. Status: clear polyaspartic; 100% solids, UV stable, cures to 15°F.
• Flake specification. Size, broadcast rate and UV stability are all still to be fixed. Status: Quarter inch, 0.2 lb per sq ft, broadcast to refusal.
• Chemical resistance chart. Status: reagent-by-reagent resistance chart not yet supplied. Why the chemistry is described but no reagent list is published.
• Performance tests on the ANVIL build. No hot tire, slip, abrasion or pull-off adhesion test has been run on this system, which is why no such figure appears above.
• Whole-system film thickness. Each layer publishes its own thickness, but no sheet states what the finished build measures once the flake is in it, because that depends on how much flake the floor takes.

Transport classification came off this list in September 2026 and is recorded under Health and safety above. If you need a value that is not on this page, ask. If we have it we will send you the document it came from, and if we do not have it we will say so. Get in touch.
