Concrete Coatings and Resinous Flooring

Compared to other coating steel concrete can be an extremely difficult and expensive endeavor without the proper products and guidance. But floor coatings are critical to safe, efficient operations because they can reduce slip and trip hazards, protect concrete from harmful spills and heavy abuse and increase an operation’s overall workplace environment. At best, underestimating the necessity of the right warehouse floor coating can hold an operation back from running at peak efficiency. At worst, it puts employees lives and assets at risk and firms on the hook.

Enhance safety, efficiency and aesthetics with resinous floor coatings

In settings where heavy shelves and forklifts are used, the right warehouse floor coating can protect concrete from cracking and chipping as well as the harmful effects of spilled chemicals. Coatings also protect people. Workers can move more safely on floor coatings engineered to resist slips and trips.

While it may seem frivolous to labor over what color to paint a floor, the right color does more for a space than meets the eye:

  • Spilled chemicals can be located and cleaned more easily when they contrast with the color of a floor coating. Differing floor coating colors can also separate sectors of a warehouse. This increases efficiency and reduces the risk of confusion and accidents.
  • Utility bills in warehouses add up. But the right warehouse floor coating can reflect light, keeping spaces more brightly lit. High-gloss coatings can reduce the cost to light a space or lead to the reduction in amount of lights used.
  • Aesthetics do matter. While a floor’s coating can add value in terms of safety, efficiency and asset protection, they’re also more pleasing to look at. Certain colors can even improve workers’ moods.

Comparing coating systems

The advantages and disadvantages of the many available coating systems mean decision makers must assess the work done in their spaces, the safety concerns present in those settings, their project budget and time constraints. Here’s a quick roundup of warehouse floor coating systems:

  • MMA – Low-glare Methyl Methacrylate (MMA) systems are resistant to some acids, alkalis and solvents and boast a fast cure time—you can walk on an MMA-coated surface in fewer than two hours. MMA can be applied at lower temperatures, can withstand elevated temperatures and has a much higher dry film thickness (DFT) than other systems, making it resistant to scratching. But floor preparation cannot be overlooked as MMA systems don’t bond as well to substrates compared to other options. Good ventilation is required when applying odorous MMA coats. MMA systems require as many as four coats and are costlier compared to other systems.
  • Epoxy and urethaneThese systems also resist chemicals well and boast high hardness. Their dry film thickness is on par with other coatings systems, require three coats and are among the less costly alternatives. But these systems do not cure quickly. The walk-on time of 24 hours is among the longest of the available systems; because each coat takes longer to cure, the total project time takes nearly two days.
  • 100% solids epoxy – These systems stand up to abrasion and chemical spills and can be applied to floors as part of a multi-part system or on their own. Because these coatings are 100% solids, their wet film thickness and dry film thickness are identical. That means no thickness is lost due to evaporation of harmful volatile organic compounds (VOCs). For this reason, 100% solids epoxy coatings are safer to use. They’re also the cheapest option, but they do not cure quickly —walk-on time is up to 24 hours.
  • Polyaspartic – This hybrid system is an offshoot of epoxy and urethane systems that offers the advantages in a single coating what two coatings of epoxy and urethane systems can muster. Adjustments in polyaspartic formulations allow for curing times that suit individual projects and can be applied well below freezing. Walk-on time is just four hours and polyaspartics are safer to use due to only moderate odors. These systems are costlier than epoxy / urethane and 100% solids systems but offer better flexibility compared to the other options. Check out  GripCrete 9000 PA.

US Coatings systems suit various needs

No industrial setting is identical, so one coating type certainly doesn’t fit all settings. That’s why US Coatings offers a range of floor coating options made to suit your individual needs.

GripCrete 200 SL – This 100% solids flooring epoxy is recommended in interior spaces where abrasion resistance or chemical protection is desired, including warehouses, service centers and commercial buildings. It can be used alone or in a multi-coat system.

GripCrete 200 SL can be applied directly to concrete but the risk outgassing / pinholing is reduced if the surface is primed. See additional GripCrete 200 SL specs here.
