PUMA coating: game-changer or just hype?
Protecting concrete surfaces like decks or foundations can feel overwhelming with so many options to choose from. There’s a good reason for the overload – concrete comes in all sorts of types with different lifespans.
PUMA (polyurethane methacrylate) systems are one of the newer players, but they’ve quickly gained attention. They offer a fast solution without giving up durability.
If you're always on the lookout for the next great solution, don’t count out PUMA coatings until you’ve seen what they can do. Keep reading to learn about the different types, uses, and benefits for commercial concrete protection.
At nearly every nook, angle, and crevice, commercial concrete construction is at risk. Your system can sustain critical damage in a variety of ways:
PUMA is an advanced coating for waterproofing and concrete protection, meeting high demands in turnaround time, durability, and general performance.
PUMA and PMMA (polymethyl methacrylate) coatings – especially PUMA – are earning their stripes in construction circles because of their high performance.
Their key traits to consider in your next project are:
Despite being a multicoat system, PUMAs need only 45-60 minutes to cure between coats. This minimizes facility downtime, often allowing property owners and managers to make same-day repairs.
Pull testing shows that PUMA/PMMA systems offer outstanding adhesion to most surfaces. On concrete, some systems have recorded values up to 251 psi (based on the ASTM D7234 test method).
These innovative coatings are more resistant than other waterproofing membranes to:
Getting protection up front means you can reduce maintenance and repairs later. At some vendors, a PUMA comes with a warranty of 20+ years for certain applications, while standard urethanes receive one for only 5-10 years.
PUMA-based coatings thrive in cold weather, unlike standard urethane products. You can apply them in temperatures down to 0°F. This flexibility allows you to keep making progress in wintry months.
Anytime you choose a protective system, it should be on a case-by-case basis. That said, the various types of PUMA/PMMA waterproofing membranes make sense for a variety of projects and job sites.
The true PUMA system is the best balance of wear resistance and turnaround on the market.
A highly flexible material, PUMA technology offers more elongation than its offshoots. It’s specially built to meet tough demands on commercial job sites:
The high performance of PUMA and related systems doesn’t have to come at an aesthetic cost. You can customize the look by adding any color to a tintable base or adding quartz or color flakes under a clear topcoat.
In dynamic (high-movement) applications, PUMA is king, and the price reflects that. While it won’t cost a king’s ransom, it is higher than those of some other coatings.
What is PMMA? In this case, a coat by any other name is still a coat. You may know PMMA as acrylic or acrylic glass. Others know it by trade name:
The PMMA coating process isn’t much different. At first glance, it’s hard to even tell the difference in PMMAs vs. PUMA systems. Technically speaking, though, a PMMA isn’t a PUMA.
A PMMA is used for low-to-medium-movement applications. Though PMMA coatings are flexible, they have very limited elongation capabilities. PUMA shares all the features and benefits of PMMA without the limited elongation, outpacing the latter even in high-movement applications.
This offshoot is a top performer that specializes in traffic coating waterproofing for the heaviest-duty applications. It’s for extreme-wear concrete areas like:
(For an example, check out this Tremco PUMA/poly waterproofing system.)
Application happens even faster, but the cost is closer to regular polyurethane.
Subcontractors and project managers generally don’t like surprises, but here’s a good one: PUMAs are more diverse than you may have heard. PUMA systems excel in many applications, not just the traffic-coating they’re most famous for:

There’s more than one way to save a concrete build. Popular and established alternatives to PUMAs and PMMAs include:
As usual, consider your project specifics before making a purchase solely based on price or quality. Your construction product supplier should be able to guide you to the right solution.
Frequently Asked Questions About PUMA CoatingHere are some of the most frequently asked questions about PUMA Coating: What Are The Environmental And Safety Impacts Of Using Puma Coatings?Like many industrial-grade materials, while PUMAs are efficient and durable, their application can release volatile organic compounds (VOCs), which may impact air quality if not properly managed. It's essential to follow safety guidelines, including proper ventilation during application and the use of personal protective equipment to avoid inhaling fumes. Environmentally, some PUMA systems may have specific waste disposal requirements to prevent harmful chemicals from entering water sources. Manufacturers often offer low-VOC options to reduce these environmental impacts, so it's important to check the product specifications. Can I Apply Puma Over Existing Coatings, Or Do Surfaces Need To Be Fully Stripped First?PUMA coatings can often be applied over existing surfaces, depending on the condition of the current coating. The surface must be properly prepared, meaning it should be clean, dry, and free of contaminants like oil, dirt, or loose material. In some cases, minor surface imperfections are OK, but larger defects or degraded coatings may require stripping before PUMA will adhere properly.. Consult with the coating manufacturer or a distributor to determine the best preparation method for your specific project. Are There Any Limitations Or Downsides To Using Puma In Certain Conditions?PUMA coatings work great in many places, but they have some drawbacks. They cost more than other options, which might not suit tight budgets. While PUMA handles cold and movement well, it can wear out if constantly exposed to lots of movement or strong chemicals. |
PUMA coatings are a commercial-grade solution for construction jobs that require waterproofing or other concrete protection. The point is to pay a little more for a high-end product now, helping you avoid durability issues later.
There are three primary benefits to a PUMA system:
Compared with typical urethane systems, PUMAs and PMMAs are more ready-made for projects with tight launch windows and strict performance needs.
