Polyaspartic Coating

Polyaspartic coating provides fast, reliable, durable protection

Polyaspartic coating may be the new kid on the block when it comes to polymeric coatings, but it is rapidly gaining in popularity due to its range of attractive and versatile properties. It is rapid curing (from 5 minutes to 2 hours), can be applied in a range of temperatures, is UV resistant (particularly helpful Downunder), has strong adhesion, and is highly resistant to chemicals, heat, and water.  Polyaspartic coating is most widely used as a concrete floor coating in industrial, residential, and commercial sectors, but it also finds ready application in other fields including construction, corrosion protection, bridge coatings, tank coatings, and more.

In this article we look at polyaspartic coating and its applications, and how it performs compared to other polymeric coatings like epoxy and polyurethane. We also list companies and manufacturers providing polyaspartic coating in Australia.

Polyurethane vs polyurea vs polyaspartic coating comparison

The three big “poly” coatings are in fact all related chemistries – polyurethane, polyurea, and polyaspartic are all formed through the reaction of an isocyanate with a resin. The main difference lies in the resin component. At its most basic, the isocyanate component of polyurethane reacts with a polyol, for polyurea it is an amine, and polyaspartic uses a diamine. Polyaspartic coating is therefore a form of polyurea, also known as aliphatic polyurea.

What all this technical description is getting to is this: these coatings all share a number of properties, but not in equal degrees. They all have differing requirements and capabilities, and some have shortcomings that the others do not share.

  • Polyurethane – Is sensitive to moisture and temperature when being applied. Requires a catalyst.
  • Polyurea – Discolours on exposure to UV radiation. The cure speed and heat required for application mean it requires a bulky spray apparatus which decreases the number of suitable applications.
  • Polyaspartic – Reacts and cures rapidly once the two components are mixed. They also have a lower moisture transmission rate than polyurea and polyurethane meaning they can be applied at a lower thickness. UV stable.

Why to choose polyaspartic coating

Like the other “poly” coatings, polyaspartic coating is durable, tough, and versatile. It has a range of properties that make it a desirable option for any project:

  1. Rapid curing, easy application  – Polyaspartic coating is applied with a squeegee, broom, or a roller, and can be applied across a range of temperatures (including sub-zero temperatures). With little to no VOCs and a rapid cure time, polyaspartic coating is easy to apply, and requires very little downtime – meaning a fast return to service.
  2. UV stability – Unlike epoxy, polyaspartic coating is UV stable and does not suffer any negative effects when exposed to sunlight. This means it can also be used outside, as it also has excellent weatherability.
  3. Strong adhesion and durability – Polyaspartic is highly adhesive due to its excellent wetting characteristics, and the coating forms a smooth, seamless surface that is highly durable under a range of conditions.
  4. High resistance to chemicals – Resists oils, acids, salts, fats, and other industrial chemicals.
  5. Abrasion and impact resistance -Polyaspartic exhibits similar abrasion and scratch resistance to polyurethane.

How to use polyaspartic coating – flooring, bridges, and more

Polyaspartic coating has quickly found ready application in a wide range of industries and environments. Its high performance properties make it a perfect fit for protection and decoration purposes. Below is a list of just three of the most popular uses for this coating.

  1. Polyaspartic floor coating
    No discussion of polyaspartic coating would be complete without mentioning flooring. As a floor coating, polyaspartic provides a seamless hygienic surface, UV resistance, cold temperature application, chemical and water resistance, and an attractive finish. Suitable for use in any environment.
  2. Polyaspartic coating for exterior use
    The UV resistance of a polyaspartic coating is a big advantage over more traditional epoxy coatings when it comes to exterior applications. Add to that its excellent abrasion resistance and rapid curing time, and polyaspartic coating outperforms the alternatives. Applications like bridge protection and highway projects are perfect examples.
  3. Polyaspartic tank and storage coating
    The waterproof, impermeable, chemical resistant properties of polyaspartic means it has found ready use in tank coating, storage, sewer and water treatment facilities, pipelines and even swimming pool coatings.

    I recently ( 2 weeks) had old stencil driveway resurfaced to flake epoxy and polyaspartic coating (All purpose coatings Sparta 60). I’ve noticed that in 2 weeks it has got discoloured (bit yellowish light brown). Polyaspartic coating is UV stable so I did’nt expect this so soon.

    The strip between garage n driveway was also coated, and I can see colour outside the garage door is different than the strip where the door closes

    Appreciate any thoughts what might be causing it. Also any suggestions to resolve this. Do I need to have the coating strip off if possible and recoat with a different coating?

    Help please

      Dear Vivek,

      Thank you for your enquiry about polyaspartic coating. From your description, it does sound as though the coating is yellowing from UV exposure, although this ought not to be a problem with Sparta 60. It is difficult to assess from description alone. If you had a professional apply the coating we recommend you give them a call so that they can advise you as to the cause and solution, or contact the coating manufacturer. In any case, we recommend you contact your local professionals to get advice as to whether you need to strip the coating or if there is a less drastic solution. We wish you the best of luck with your driveway.

      Best regards,

      Sofia – Coating.com.au
