Durability
What the system resists, and the evidence behind each claim.
A garage treats a floor worse than most factories do. A jack stand puts most of a car onto three feet the size of a coaster. A hot tire bonds itself to the surface and pulls as it cools. A dropped socket arrives at speed, road salt sits in the same spot all winter, and the slab underneath everything moves with the seasons.
Here is what the manufacturer’s own data establishes about each of those — and, separately and further down, the laboratory strength figures, two of which we now hold.
The hot tire question
This is the one that kills garage floors, so it is worth being precise. A tire coming off a motorway is hot and slightly soft. It sits on the floor, cools, and grips. A cheap coating lets go — the tire lifts a disc of it away, and the floor is finished.
Two things decide whether that happens. The first is bond, which is preparation, and which is your part of the job. The second is whether the film softens under a warm tire at all — and that is published. The clear topcoat’s maximum dry service temperature is 200°F, the body coat beneath it 250°F. A tire at the end of a long drive is well under either.
What holds it to the slab
Every layer in this system is rated Excellent for adhesion by its manufacturer, and every layer is 100% by weight solids. The second figure matters more than it sounds. A solvent-borne coating is part solvent, and the solvent leaves — what you roll out is not what stays on the floor. At 100% solids, it is.
The primer does the actual gripping, and it is engineered to be tolerant of surface impurities such as oil and grease. That is the honest answer to “my slab has twenty years of oil in it”: it penetrates and seals rather than sitting on top and hoping.
When the slab moves
Concrete is not static. It moves with temperature, with moisture, and under the wheel of a car crossing it. A film that is hard but brittle cracks under that flexing, and a crack is where water gets in.
The primer, the body coat and the clear topcoat are each rated Excellent for flexibility. The base coat is a polyaspartic engineered, in the manufacturer’s words, for exceptional toughness and resiliency — an impact-resistant material before it is a decorative one.
The limit worth naming: no coating bridges a moving crack in concrete. If the slab cracks, the coating over it cracks. That is a slab question rather than a coating question, and nothing on the market solves it.
How much material is actually there
Some of durability is simply thickness. The clear topcoat alone goes down at 12 mil nominal, over a body coat at 80 sq ft per gallon at 20 mil, over a primed and sealed slab. A one-coat garage floor paint is measured in single figures of mils. This is a built system, and the flake is buried inside it rather than sitting on top where it wears through.
Where else this material is used
The body coats carry USDA acceptance under FSIS Directive 11,000.4 (Rev. 1) — cleared for food processing floors, which are washed down daily with hot water and caustics. The manufacturer’s ordinary work is corrosion-resistant lining for chemical plants and wastewater treatment. A garage is not a demanding application by those standards, and that is precisely the point of specifying it this way.
The strength figures
Coating manufacturers often publish laboratory strength figures — compressive, tensile, flexural, hardness. None of the five data sheets for this system prints them. The sheets give qualitative ratings instead: adhesion Excellent, flexibility Excellent.
So we asked. Duromar gave us the compressive strength and the hardness directly, and those two are theirs. Tensile and flexural they have not given us yet, and the figures shown for them are typical of this class of coating rather than measurements of this one — which is why they are labelled that way in the table and the others are not.
Two of these we can attribute to the manufacturer. Two are context until they can be:
| Property | Test method | Value |
|---|---|---|
| Compressive strength | ASTM C-579 | 11,000 psi |
| Tensile strength | ASTM D-638 | 5,000 psi typical |
| Flexural strength | ASTM D-790 | 7,500 psi typical |
| Hardness, Shore D | ASTM D-2240 | Shore D 72 |
This page once carried four such numbers. They belonged to a different coating — the product this line replaced — and they came down the moment we noticed. Publishing one product’s strength as another’s is the one mistake in this business that cannot be walked back, and an empty cell is better than a borrowed one.
Two things we will not claim
Slip resistance. no slip test run on this build. A gloss floor is slippery wet, and a broadcast surface has texture that helps — but neither of those is a measurement, and we have not run one.
Abrasion. no abrasion test run on this build. The materials are specified for industrial traffic, but no Taber figure exists for this exact build, so we do not quote one.
