Know your chemistries
Not all deck coatings are the same chemistry.
Traffic coatings are built on different chemical backbones — and the chemistry drives how a system stretches, wears, cures, and lasts. Here’s how DriveDeck’s hybrid polyurea elastomer compares with the urethane-based chemistries commonly specified for decks, using published technical data.
How to read these tables
A chemistry-level comparison, kept honest.
Values are drawn from published technical data sheets and cite their ASTM test methods. Where a chemistry’s system literature does not typically publish a value, the table says so — in both directions.
| Metric | DriveDeck — Hybrid Polyurea Elastomer | High-Solids Polyurethane Systems | The DriveDeck Difference |
|---|---|---|---|
| Chemistry & cure | Hybrid polyurea elastomer — 100% solids, solvent-free base; high-solids aliphatic top. Cures by chemical reaction between two components. | High-solids polyurethane (100% solids system). Cure depends on ambient moisture. | Polyurea offers better elasticity and chemical resistance, and a reaction cure that doesn’t wait on the weather. |
| VOC content | Base (D-Guard): 0 g/L, solvent-free. Intermediate/top (D-Grip): <100 g/L. | VOC compliant — low, but typically not published as 0 g/L. | Lower overall VOC — especially the base coat — with reduced odor during application in occupied or sensitive areas like garages. |
| Tensile strength ASTM D-412 | Base: 2,000 ± 200 psi · Top: 3,750 ± 400 psi | Typically not published at the system level. | Higher top-coat tensile strength for superior wear resistance in high-traffic zones such as ramps and turn lanes. |
| Elongation ASTM D-412 | Base: 600 ± 100% · Top: 175 ± 50% | Typically not published at the system level; comparable bases commonly run 300–500%. | Exceptional base elongation for crack-bridging — up to 1/16″ cracks without routing. |
| Tear resistance ASTM D-1004 | Base: 250 ± 25 pli · Top: 350 ± 50 pli | Typically not published. | Stronger tear resistance supports longevity against abrasion from vehicles and foot traffic. |
| Hardness ASTM D-2240 | Base: 73 ± 3 Shore A · Top: 90 ± 5 Shore A | Typically not published. | Balanced hardness: a flexible base absorbs impact while the harder top resists wear without brittleness. |
| Abrasion resistance | Not separately published; high tensile and tear values indicate strong wear performance. | CS-17 wheel, 1,000 cycles: 47–100 mg loss (ASTM D-4060). | Polyurea chemistry is known for heavy-duty vehicular service. |
| System thickness | ~73 wet mils total 8 primer · 32 base · 15 intermediate · 18 top |
~40–70 wet mils depending on traffic level 25 base · 12–25 top/intermediate |
A thicker build provides more robust waterproofing in humid, chloride-exposed environments — supporting longer service life. |
| Cure & return to service | Intercoat: 3–5 hrs · Foot traffic: 16 hrs · Vehicular: 72 hrs | Intercoat: 3–4 hrs · Foot traffic: 24 hrs · Vehicular: 24–48 hrs, extended in cool weather | Faster intercoat and foot-traffic times support phased garage work and minimize downtime. |
| Application & mixing | Notched squeegee and backroll; detail coats at cracks and joints; aggregate broadcast 15–20 lbs/100 sq. ft.; mix only what’s usable within 1–2 hours. | Similar tools and broadcast (15–35 lbs/100 sq. ft.); short pot life around 20 minutes. | A more forgiving mixing window and humidity tolerance, with light, heavy, and vehicular builds off one consistent CSP-3 prep. |
| Warranty structure | 5-year limited materials warranty (light-duty pedestrian); 10-year (heavy-duty pedestrian/vehicular) with a recoat at year 5. | Standard published material warranty commonly 1 year, extendable by program. | Significantly longer defined coverage, with a built-in mid-term recoat that keeps the wearing surface maintained. |
| Additional performance | Vapor-drive-tolerant primer options; ADA-compliant slip resistance; chemical resistance to oils, salts, and more. | Skid resistance; seamless; freeze/thaw protection. | Superior vapor-tolerance options (including multiple primer applications for slab-on-grade conditions). |

| Metric | DriveDeck — Hybrid Polyurea (2-Component) | 1-Component Solvent-Based Aromatic Urethane | 2-Component Fast-Cure Urethane | The DriveDeck Difference |
|---|---|---|---|---|
| Chemistry | Hybrid polyurea elastomer, 100% solids base | Single-component, solvent-based aromatic urethane | Two-component fast-cure urethane (aromatic base + aliphatic top) | True polyurea chemistry — faster cure and better moisture tolerance. |
| VOC content | Base: solvent-free (0 g/L) · Top: <100 g/L | Higher — typically 190+ g/L | Lower than single-component; some versions <22 g/L | Lowest overall VOC — better for occupied garages. |
| Tensile strength | Base: 2,000 psi · Top: 3,750 psi | Base: ~1,200 psi | Base: ~1,500 psi · Top: ~2,000–2,200 psi | Significantly higher top-coat strength for abrasion resistance. |
| Elongation | Base: 600% · Top: 175% | ~400% | Base: 500% · Top: 80–130% | Highest base elongation — best crack-bridging in moving structures. |
| Tear resistance | Base: 250 pli · Top: 350 pli | ~100 pli | ~150–165 pli | Stronger tear resistance overall. |
| Hardness | Base: 73 Shore A · Top: 90 Shore A | 70–75 Shore A | Base: 74–79 · Top: 80–90 Shore A | A good balance — flexible base plus a very hard wearing surface. |
| System thickness | ~73 wet mils total | ~40–52 dry mils | ~40–52 dry mils (extra wear coats possible) | Thicker overall build for superior waterproofing.* |
| Cure & return to service | Intercoat: 3–5 hrs · Foot: 16 hrs · Vehicular: 72 hrs | Foot: 24–36 hrs · Vehicular: 72 hrs | Foot/vehicular: 24–36 hrs (fast-cure advantage) | Competitive speed — and polyurea is less humidity-sensitive. |
| Application | Notched squeegee + backroll; aggregate broadcast | Roller/squeegee + broadcast | Roller/squeegee + broadcast (faster cure) | Very similar methods — but polyurea is more forgiving of site conditions. |
| Warranty structure | 5-year (light) / 10-year (heavy/vehicular) with required recoat at year 5 | Project-specific (typically 5–10 yr) | Project-specific (typically 5–10 yr) | The most clearly defined long-term structure, with a built-in recoat plan. |

Why it matters
What the numbers mean for your deck.
Structures move. The membrane has to.
With 600% base-coat elongation, DriveDeck bridges cracks up to 1/16″ without routing — flexing with thermal movement and vibration instead of splitting over it.
Traffic is relentless. So is the top coat.
A 3,750 psi tensile, 350 pli tear, 90 Shore A wearing course takes the daily abrasion of tires and foot traffic while protecting the waterproofing below.
Occupied buildings stay open.
A solvent-free, 0 g/L VOC base coat and low-odor chemistry let work proceed in and around occupied garages, hospitals, and campuses with minimal disruption.
Coverage you can put in the file.
Limited materials warranties run 5 years for light-duty pedestrian systems and 10 years for heavy-duty and vehicular systems with a defined recoat at year 5 — in writing.
