At GNR Flooring we try and keep things simple. So, rather than offer a complex range of products, all with different core benefits, we work on the principle that certain performance criteria, especially outstanding slip resistance, incredible durability and ultra fast cure times are a pre-requisite.
Ultra fast 2 hour cure time at temperatures down to -30°C
Minimum downtime, rapid refurbishment, fast track new builds
Exceptional bond to most substrates including concrete, steel, tiles, other resins, asphalt and marine ply
Ability to overlay existing floors resulting in minimal disruption and reduced costs
Ultra strong chemical bond between layers, creating a truly monolithic finish
Outstanding durability, can be easily refurbished and repaired
Outstanding slip resistance that can be tailored to project specific parameters
Unrivalled levels of safety
Unrivalled range of decorative finishes
Bespoke installations, matches to existing finishes
Seamless and impermeable
Easy to clean, hygienic, outstanding durability
Flexible finishes that do not shrink
Ideal for low temperature installations and external installations - excellent resistance to cracking and weathering, better detailing, outstanding durability

Colour stable, can be installed outside, ideal for almost any environment
MMA v Epoxy
Cure Times
Cure times affect how quickly an installation can occur and then how quickly the floor can be returned to full use (or other trades come back into the area to work).
MMA vs Epoxy / PU
Time to full physical cure
(i.e. able to fully traffic) 2 hours vs 12 – 48 hours
Time to full chemical cure
(i.e. able to fully use) 2 hours vs 3 – 10 days
It should be noted that whilst you can walk on an epoxy or polyurethane floor when it has reached physical cure, these systems should not be subjected to full operational use until full chemical cure is achieved.
In simple terms, the ultra fast cure times of our products enable faster installations and much faster return to full use.
Installation Temperature
MMA can be installed at temperatures down to -30°C without any detrimental affect on cure time. The same cannot be said for Epoxies and Polyurethanes. In most cases, these products should not be installed at temperatures of less than 5-10°C, with optimal cure occurring at approx. 20°C.
The speed of cure for epoxy or polyurethane installations is greatly affected by temperature. The higher the temperature, the faster the cure (please note most epoxy and polyurethane specification sheets quote cure times at 20°C). However, if epoxies and polyurethanes are exposed to temperatures below 5°C during the curing process, there is a high probability that the installation will be compromised.
Speed of Installation
Nearly all resin systems are installed in multiple layers (primer, main body coat layer, seals etc). As Degafloor products cure fully in just 2 hours, there is no real downtime between the application of each layer. However, epoxies and polyurethanes typically need at least 4 - 8 hours to cure between applications, resulting in significantly longer installation periods.
Bonding Technology
MMA resins are thermoplastics which achieve a chemical bond between each installation layer, resulting in a monolithic finish. In reality, each new layer chemically fuses to the previous layer (or existing subfloor) creating a virtually unbreakable bond.
Epoxy and polyurethane resins are thermosetting and achieve only a mechanical bond between installation layers. In reality each new layer 'sticks' to the previous layer (or existing subfloor).
Detailing
Our resin flooring systems do not shrink and accordingly installation is both simple, repeatable and the finished floor reliable.
PU floors often require retention chases to be cut into the floor, and at all termination points, to try and offset the shrinkage stresses that occur when the floor cures. This complicates the installation and can result in performance problems.
Additionally, Our resins can be bonded directly to drainage channels and other potential areas of weakness to create reliable and durable installations. In many cases polyurethane and epoxy finishes will require an expansion joint to be installed in these areas which creates a weakness that is often the cause of future issues.
Slip Resistance
Our Systems offers a range of solutions to meet varying slip resistance requirements. This is especially true of industrial environments, where outstanding performance is required.
Our Degafloor FB and QTA systems utilise quartz aggregate which stays suspended at the top surface of the system creating a consistent and textured finish that delivers marketing leading performance. Whereas, most polyurethane systems are trowel applied and rely on the installer leaving part of the aggregate within the resin mix 'exposed' to create slip resistance. This method often results in an inconsistent surface finish and together with early wear can result in unsatisfactory slip resistance.
Durability
Degafloor resins are totally UV resistant and do not become brittle with age. Many polyurethane resins are not UV resistant creating long-term performance issues (including discolouration). Additionally, some epoxy formulations have been proven to become brittle over time resulting in poor long term performance.
Temperature Resistance
Product Temp Resistance
Epoxy Up to 60°C
Degafloor Up to 80°C
Polyurethane Up to 120°C
Degafloor products offer excellent temperature resistance at a thickness of just 4mm. However, polyurethane resins can withstand temperatures of up to 120°C when installed at a thickness of 9mm.
Based on our experience it is rare that a customer actually needs a floor that can resist high temperatures, often finding that small changes in operating procedures avoids high temperature liquids coming into contact with the floor.
