What You Need to Know about Polyurea Coatings on Parking Decks

← Back to List
What’s the first thing that comes to mind when you think of parking decks? No doubt it’s the fact that the large concrete structures need structural integrity to hold heavy weight. Durability is crucial, and waterproofing certainly helps. And, that’s why polyurea coatings are a top industry consideration.

One of the greatest properties of polyurea is its versatility. Consequently, few substances can compete with its adaption to concrete structures. For starters, it well exceeds the integrity of the untreated concrete. Next, there are limited problems regarding adhesion or shrinkage. No doubt, the idea of sealing out moisture is crucial when erecting parking decks.

Parking Decks Need Protection


Like bridges, parking decks have a constant stream of heavy vehicles passing through. The average passenger car weighs approximately 4,000 pounds. When you multiply that times garage capacity, there’s a clear need for structural integrity.

So, why polyurea coatings? It might seem that concrete is durable on its own. In many cases, parking decks are not solely constructed of concrete. Although steel adds some stability, it also comes with its own set of issues. Here are some reasons polyurea coatings are ideal for parking decks made of concrete and steel:

  • Combats moisture exposure and corrosion

  • Shields against abrasions to concrete

  • Fills in cracks caused by weather exposure

  • Protects against changes in temperature

  • Contains a chemical resistance component


When it comes to existing parking structures, there are concerns about surface preparation before application. Be that as it may, it is important to speak with a company that offers sound technical advice regarding its product. At Marvel Coatings, we pride ourselves in discussing all aspects of the job.

One primary concern in preparing parking decks for polyurea coatings is contamination. As a matter of course, sitting cars may leak oil or other fluids. Vehicles may also track in salt used for protection against ice or snow. Additionally, tire frictions can create large cracks and abrasions. Since polyurea acts as a sealant, it is more efficient when the surface is properly prepared.

Obviously, surface preparation is the first step in polyurea coating application. The fact that the application works in both humid and colder temperatures is another plus. Set up can be done faster than most other types of products. Polyurea also cures quickly and therefore allows only a slight time lapse in a return to parking availability.
