Can hot tire marks be prevented on an epoxy-coated garage floor in Ottawa

Preventing Hot Tire Marks on Your Ottawa Epoxy Garage Floor

Yes, hot tire marks can absolutely be prevented on an epoxy-coated garage floor — but it requires choosing the right topcoat system from the start. Hot tire pickup is one of the most common complaints about garage floor epoxy in Ottawa, and it happens when warm tires from driving on sun-baked summer pavement transfer heat to the epoxy surface, softening it enough to pull the coating away from the concrete or leave discoloured marks. In Ottawa, where summer pavement temperatures can exceed 50 degrees Celsius on roads like the Queensway, Highway 417, and surface streets, this is not a theoretical concern — it happens regularly on improperly coated floors.

The single most effective prevention is a polyaspartic or urethane topcoat applied over your epoxy base. A polyaspartic clear coat has a much higher heat tolerance than epoxy alone, typically resisting temperatures well above what any tire will reach during normal driving. It adds $2 to $4 per square foot to your project cost — roughly $800 to $2,400 for a standard two-car garage — but it eliminates the hot tire problem almost entirely. Polyaspartic also provides UV stability, chemical resistance against road salt, and superior abrasion resistance, making it the ideal topcoat for Ottawa conditions. A urethane topcoat offers similar heat resistance at a comparable price point and is the other professional-grade option for preventing hot tire marks.

Understanding why hot tire pickup happens helps explain why the topcoat matters so much. Standard epoxy — even 100 percent solids epoxy — has a relatively low heat deflection temperature compared to polyaspartic and urethane coatings. When a tire heated to 70 or 80 degrees Celsius from highway driving sits on epoxy, the heat softens the coating's surface. As the tire cools, it bonds to the softened epoxy. When the car moves, it pulls coating material with it, leaving a mark or bare spot. This is especially problematic in Ottawa during July and August when daytime temperatures exceed 30 degrees Celsius and vehicles bake in parking lots all day before coming home to the garage.

Water-based epoxy is the most susceptible to hot tire pickup because of its thin film and lower chemical resistance. If you have a water-based epoxy floor without a topcoat, hot tire marks are virtually inevitable with regular vehicle use in summer. Solvent-based epoxy performs somewhat better but is still vulnerable. Even 100 percent solids epoxy can experience hot tire marking without a protective topcoat, though its thicker film makes the damage less severe. The only coating systems that resist hot tire pickup on their own, without an additional topcoat, are full polyaspartic systems and polyurea systems — both formulated with higher heat resistance from the ground up.

If you already have an epoxy floor that is showing hot tire marks, the solution does not require stripping and starting over. A contractor can scuff the existing surface and apply a polyaspartic or urethane topcoat over the current epoxy, provided the base coating is still well-bonded to the concrete. This scuff-and-recoat approach costs $4 to $8 per square foot and adds the heat-resistant layer that was missing from the original installation. It is a cost-effective fix that extends the life of your existing floor by years.

For any new garage floor epoxy project in Ottawa, insist on a polyaspartic or urethane topcoat as part of the system specification — it is not an optional upgrade in our climate, it is a necessity. When getting quotes, ask specifically what topcoat is included and whether it is rated for hot tire resistance.
