The Main Types of Resin Flooring Explained

Resin flooring is widely used across industrial and commercial environments, providing a durable, seamless surface that can be specified to cope with everything from regular foot traffic to heavy machinery, chemicals, and demanding cleaning regimes.

However, resin flooring is not a single product. There are several types, and each offers different characteristics that make them all suitable for different environments. A system that performs well in a warehouse, for example, may not necessarily be the best choice for a food production facility, or a commercial space where aesthetics are primary, and downtime needs to be kept to an absolute minimum.

Understanding these differences is therefore an important first step towards specifying the right floor. Below, we explore the main resin flooring types, what each one offers, and the environments where they are most commonly used.

What are the Main Types of Resin Flooring?

A resin floor is created using a resin-based material that cures to form a hard-wearing surface over a suitable substrate, which will often be concrete. Depending on the required specification, the complete flooring system may incorporate primers, resin layers, aggregates, and specialist finishes to provide particular performance characteristics.

The four main resin technologies to consider are:

• Epoxy resin flooring
• Polyurethane flooring
• PMMA/MMA acrylic flooring
• Cementitious urethane flooring

Although these systems share some characteristics, there are important practical differences between them.

1. Epoxy Resin Flooring

What is an Epoxy Resin Floor?

An epoxy resin floor is typically formed by combining an epoxy resin with a hardener. The components chemically react during curing to create a rigid, strongly bonded surface.

Epoxy is one of the most established resin flooring technologies and can be specified in a variety of thicknesses and finishes depending on the environment. Its combination of durability, versatility, and cost-effectiveness makes it particularly common across industrial and commercial premises.

What are the Benefits of Epoxy Resin Flooring?

One of epoxy’s biggest advantages is its strength. Once fully cured, a correctly specified epoxy floor can withstand substantial levels of foot traffic, wheeled equipment, and general wear, making it suitable for busy working environments.

Other potential benefits include:

• Excellent adhesion to correctly prepared concrete
• Good abrasion and impact resistance
• Resistance to a range of chemicals, depending on the formulation
• A seamless surface that is straightforward to clean
• A wide variety of colours and finishes
• The option to incorporate textured or anti-slip finishes
• Good value for many general-purpose industrial applications

Epoxy flooring can also create a bright, clean-looking surface, making it useful when an older concrete floor needs more than purely functional protection.

What are the Drawbacks of Epoxy Resin Flooring?

Epoxy is relatively rigid once cured. This means that substrate movement or cracking can become an important consideration when assessing whether it is appropriate for a particular floor. Some epoxy formulations can also discolour when exposed to prolonged UV light, which can make them less appropriate for outdoor areas or spaces receiving substantial direct sunlight unless a suitable UV-resistant system or finish is specified.

Installation and curing also require sufficient operational downtime. Exact times vary considerably between products and site conditions, so this should be considered when planning work in a facility that needs to remain operational.

Where is Epoxy Resin Flooring Best Used?

Epoxy is a versatile option for many indoor commercial and industrial applications, including:

• Warehouses and distribution centres
• Factories and manufacturing facilities
• Workshops
• Garages
• Plant rooms
• Commercial premises
• Storage facilities

For businesses looking for a robust general-purpose resin surface without the specialist requirements of some other systems, epoxy can be an excellent starting point.

2. Polyurethane Flooring

What is Polyurethane Flooring?

Polyurethane flooring, sometimes shortened to PU flooring, uses polyurethane resin technology to produce a hard-wearing surface. There are many different polyurethane formulations, meaning that performance characteristics can vary considerably between individual systems.

Compared with conventional epoxy systems, polyurethane can offer greater flexibility. This can be advantageous where the flooring needs to accommodate movement, impacts, or other stresses without being excessively rigid.

What are the Benefits of Polyurethane Flooring?

Polyurethane systems can be specified to offer excellent resistance to abrasion and impact, making them suitable for demanding commercial and industrial environments.

Depending on the particular formulation, benefits can include:

• Greater flexibility than conventional epoxy systems
• Strong abrasion and wear resistance
• Good resistance to impacts
• Chemical-resistant options
• A seamless and easy-to-maintain finish
• Different colours and surface finishes
• Specialist systems for environments with demanding operating conditions

The slightly more flexible characteristics of polyurethane can make it particularly useful where the flooring will experience stresses that could be less suitable for a highly rigid system.

What are the Drawbacks of Polyurethane Flooring?

The term “polyurethane flooring” covers a broad range of products, so it’s particularly important not to assume that every PU system provides the same characteristics. Chemical, temperature, and UV resistance, for example, will depend on the formulation and complete system specified. This makes understanding the demands of the environment particularly important before choosing a polyurethane floor.

Cost can also vary according to the system, thickness, and finish required.

Where is Polyurethane Flooring Best Used?

Polyurethane flooring can be used across a wide variety of settings, including:

• Warehouses
• Manufacturing facilities
• Workshops
• Commercial buildings
• Retail environments
• Areas exposed to frequent impacts or abrasion
• Other demanding industrial environments

Where some additional flexibility is desirable alongside the durability expected from resin flooring, a suitable polyurethane system may offer advantages over a conventional epoxy alternative.

3. PMMA and MMA Acrylic Flooring

What are PMMA and MMA Flooring?

The terminology surrounding PMMA flooring, MMA flooring, and acrylic flooring can initially seem confusing because the terms are closely related.

MMA stands for methyl methacrylate, a chemical building block used in these fast-curing acrylic resin systems. PMMA stands for polymethyl methacrylate, the polymer created from MMA. In flooring, the terms MMA and PMMA are often used when discussing this family of acrylic resin systems.

Their most notable practical characteristic is speed.

What are the Benefits of PMMA Flooring?

PMMA systems can cure significantly faster than many conventional epoxy and polyurethane alternatives. Depending on the particular system and installation conditions, floors can potentially return to service within hours rather than requiring prolonged shutdown periods.

This makes acrylic flooring particularly valuable in environments where the cost or disruption of closing an area is a major consideration.

Other potential benefits include:

• Rapid curing
• Fast installation and refurbishment programmes
• Good durability
• Resistance to a range of chemicals when correctly specified
• Seamless finishes
• Different colours and surface textures
• The ability to undertake repairs or modifications relatively quickly

This can make the higher initial cost of PMMA worthwhile, where reducing operational downtime delivers a significant commercial benefit.

What are the Drawbacks of PMMA Flooring?

PMMA systems are generally more expensive than standard epoxy alternatives, so they may be unnecessary where there is no particular need for rapid curing.

MMA resins also have a distinctive odour during installation. Correct ventilation and professional installation procedures are therefore important while the system is being applied and cured.

As with other resin flooring technologies, performance will ultimately depend on the exact system selected and the quality of substrate preparation and installation.

Where is PMMA/MMA Flooring Best Used?

The speed of MMA flooring makes it particularly useful in environments where extended closures would be difficult or expensive, such as:

• Retail premises
• Food and beverage facilities
• Healthcare environments
• Commercial buildings
• Manufacturing facilities
• Public buildings
• Areas requiring rapid refurbishment

For a business that needs to get a floor back into service as quickly as possible, PMMA can offer a significant practical advantage.

4. Cementitious Urethane Flooring

What is Cementitious Urethane Flooring?

Cementitious urethane flooring, also commonly known as polyurethane cement, combines polyurethane resin technology with cementitious components and aggregates to create a particularly robust flooring system. Rather than simply offering general wear resistance, these systems can be specified for environments involving some of the most demanding operating conditions.

What are the Benefits of Cementitious Urethane Flooring?

One of the major advantages of cementitious urethane is its ability to cope with environments involving temperature changes, moisture, and intensive cleaning.

Depending on the specification, advantages can include:

• Excellent resistance to thermal shock
• High resistance to abrasion and impact
• Resistance to a wide range of chemicals
• Suitability for frequent and intensive cleaning
• Good performance in wet environments
• Heavy-duty durability
• Slip-resistant finishes, where required

For example, floors in food-processing environments may regularly encounter hot water, steam, cleaning chemicals, oils, food products, and heavy equipment. A suitably specified cementitious urethane floor can be designed with these demands in mind.

What are the Drawbacks of Cementitious Urethane Flooring?

Cementitious urethane tends to have a more functional, industrial appearance than some decorative epoxy, polyurethane, or acrylic systems. If aesthetics are the overriding priority, another resin technology may therefore offer more options.

It is also a specialist heavy-duty system and may represent unnecessary performance and expense for a relatively light-duty environment.

Where is Cementitious Urethane Flooring Best Used?

Cementitious urethane is particularly suited to demanding industrial environments, including:

• Food and beverage production facilities
• Commercial kitchens
• Breweries
• Dairies
• Processing facilities
• Manufacturing environments
• Wet production areas
• Facilities that frequently undergo intensive cleaning and washdowns

Where a floor needs to withstand a combination of heavy use, chemicals, moisture, and temperature fluctuations, cementitious urethane can provide characteristics that a more general-purpose resin floor may not.

How Do the Different Types of Resin Flooring Compare?

There is no single resin technology that is automatically the best choice for every application. Instead, each has particular characteristics that lend themselves to different operational requirements. The resin itself is also only part of the specification. Thickness, aggregates, primers, surface texture, and additional finishes can all influence how the completed floor performs.

Which Type of Resin Flooring Should You Choose?

Choosing between resin systems starts with understanding what the finished floor will actually experience. One of the first considerations is traffic and loading. A lightly trafficked commercial area has very different requirements from a warehouse where forklifts, pallet trucks, and heavy equipment repeatedly travel over the surface.

Chemical exposure also matters. Manufacturing processes, oils, cleaning agents, and other substances can affect flooring differently, so the substances likely to come into contact with the floor should form part of the specification.

Other factors include:

• Temperature and thermal shock
• Impact and abrasion
• Moisture levels
• Cleaning and washdown routines
• Hygiene requirements
• Required slip resistance
• UV exposure
• Existing substrate condition
• Available installation time
• Acceptable operational downtime
• Appearance and colour requirements
• Project budget
• Expected service life

These considerations help explain why two superficially similar facilities might require very different floors.

If minimising operational downtime is the overriding concern, for example, a PMMA system may be worth the additional investment. If the floor will experience intensive cleaning and major temperature fluctuations, cementitious urethane may be more appropriate. For many general industrial applications, epoxy or polyurethane flooring can provide an effective balance between performance and cost.

The condition of the existing concrete substrate must also be considered. A high-performance resin system cannot compensate for every underlying problem, which is why assessment and correct preparation are fundamental to a successful installation.

Choose Resin Flooring That Fits Your Environment

Epoxy, polyurethane, PMMA, and cementitious urethane each have situations where their characteristics become particularly valuable. Understanding traffic levels, chemicals, temperatures, cleaning requirements, downtime, and the condition of the substrate makes it possible to narrow those options down and build a flooring specification around how the space will actually be used.

The best resin flooring system is ultimately the one specified around the demands of the building rather than simply the material with the longest list of benefits.
