    Eleven concrete coating products and their suppliers

    Nathan Johnson

    Polyurethane Methacrylate (PUMA) - the new concrete coating on the block
    Crack control coatings: elastomeric paints and precast concrete

    The major players for protecting concrete and other linings, outside of the basic acrylic sealers, are epoxies, polyurethanes, polyureas and, more recently, polyurethane methacrylate (PUMA), and there are a host of companies in Australia that can offer versions of most.

    Generally speaking, epoxies are cheaper and have great resistance to chemicals, polyurethanes will flex with moving concrete and resist cracking, polyureas are quick drying, and PUMAs can be applied in extreme temperatures.

    While specifying concrete coating products may seem incredibly arduous, incorrect specification is worse and choosing the wrong coating can have horrible ramifications that are costly both in the immediate and long-term.

    Appropriately, concrete coating manufacturers will nearly always recommend you seek a coating specialist, usually one accredited to apply their product, before specifying and applying their product, particularly for use on concrete flooring.  

    Some considerations include:


    • Is it structurally sound, clean and free from curing components and laitance (a by-product of water in fresh concrete)?
    • Has it been properly prepared in terms of levelling, patching and roughing?
    • Has it been adequately cured? Some coating products need concrete to cure for longer in order to adhere properly.


    • Will it be exposed to chemicals? Which chemicals?
    • Will it be exposed to temperature fluctuations, heat from cleaning processes or low temperatures (refrigerators and freezers)?
    • What impact will it be subject to: high foot traffic, forklift traffic or any traffic with steel wheels?


    • How fast do you need to turn the surface around? Some products can be walked on within hours, others need days before they are fully cured
    • How difficult is your space to coat? Some products are easy to use in tight spaces and around drains etc. while others are sprayed on, need a lot of careful masking to address overspray and will “curl up” if not properly adhered around drains, crevices etc.
    • Maintenance: will it need to be cleaned regularly with chemicals, will it need recoating regularly?
    • Cost

    Below are eleven products available to the Australian market that are suitable for different applications. Most listed can be specified with non-slip, anti-bacterial or chemical-resistant additives.
