MMA and PUMA Flooring Explained

From ESD to PU there are several acronyms in the world of flooring. Knowing what they all mean is one thing, but understanding key differences of the flooring solutions themselves is another. In this post we hope to explain the similarities and differences between MMA and PUMA flooring, and help you to decide which is the right system for you.

What is MMA?

Methyl methacrylate (MMA) technology is typically a fast curing, impermeable acrylic floor coating range that can be applied at low temperatures. A key benefit of MMA systems is the versatility available in terms of both design and applicability.

Characteristics of MMA

1. Speed of Cure

MMA systems are incredibly fast curing, and can cure in minutes, even at -20°C. This is achieved by using a catalyst to trigger the reaction and begin the cure. The amount of catalyst used depends on the ambient conditions and because of this, it’s the only system where you can adjust its reactivity. Being able to adjust how long you have to work the system can help to improve workflow and efficiency, where as with the others you don’t have a choice.

2. Monolithic Structure

MMA works by fusing to previous flooring systems to become monolithic and tough. This is extremely useful for refurbishments, as MMA layers can be applied to a wide variety of substrates.

Factors to Consider

Although fast to cure, MMA gives off a strong odour during application. This odour is heavier than air however, and so good extraction can be put in place until the floor is cured.

For MMA to cure, oxygen must be absent meaning that the system has a minimum thickness that must be adhered to for a complete cure. Thicker layers can come with increased costs, however thicker layers are often more durable, and can save money in the long run thanks to an extended life cycle.

What is PUMA?

Polyurethane methacrylate is a hybrid system that reacts like MMA but performs like a PU system. Advantages of PUMA or PU systems include fast curing properties, the ability for inter-coat fusing, oil and battery acid resistance and many more. In addition to these advantages, PUMA is well suited to areas where standard epoxies and PU systems have limitations, thanks to these key characteristics.

Characteristics of PUMA

1.Weather Resistance

Thanks to PUMA’s ability to be applied in varying weather conditions, withstanding exposure to rain, UV and heat during application and after cure, it is ideal to use on exposed surfaces, such as the top level of a multi-storey car park. Here, the coating would be constantly exposed to the elements and would also need to withstand heavy traffic and abrasions that are expected in car parks. In contrast, PU systems cannot be applied to substrates that contain moisture or withstand thermal cycling issues, which PUMA systems have the ability to deal with.

2. Decorative

Some PUMA systems, such as the unique Mondéco Rapide from Flowcrete are extremely decorative but have the fast curing abilities of standard PUMA systems. This means that you can create seamless resin terrazzo floors very quickly. Flooring systems like this can be applied and cured during most normal hours of business closure.

System Similarities

Whilst the differences of these systems make each well suited to different spaces, there are several shared characteristics for MMA and PUMA systems, such as:

Temperature and Fire Resistance

Being resistant to fire and extreme temperatures, these floor coatings are often used in industrial and commercial kitchens where exposure to hot ovens or cool storage rooms needs to be tolerated.

Chemical Resistance

Resistance to chemicals from food, drink or harsh substances such as petrol, diesel and other flammable liquids make these coatings well suited to car park areas, as well as food and beverage facilities.

Slip Resistance

Anti-slip materials are incredibly useful for public spaces such as car parks, which can become slippery due to weather conditions or leaked solutions such as oil from vehicles. MMA and PUMA systems are largely impermeable as well, meaning that exposure to wet weather conditions will not cause floor failure.

UV Resistance

Both MMA and PUMA systems are UV resistant, meaning that neither system will fail when exposed to sunlight.

To conclude, both MMA and PUMA systems are fast curing, slip resistant, UV and chemical resistant flooring solutions. MMA systems are well suited to refurbishment projects thanks to its ability to be applied to a variety of substrates. PUMA systems are ideal for projects that need an extremely quick turnaround, even in challenging environments such as exposed decks that must deal with thermal cycling during and after application.
