Restoration of Hangar Floors with Rhino ArmaFloor 500

Rhino ArmaFloor 500 DF



When concrete floors age they become discoloured, stained, cracked, chipped, and weakened.

These were the same problems Qantas Defence Services needed to be addressed when it came time to upgrade the 60-year-old concrete floor of the RAAF Base Richmond hangar.

Due to budgetary constraints replacement of the floor was out of the question, restoration was the only way forward.

Tenderers were required to address certain criteria to win the project. In addition to the more mechanical properties of a suitable floor coating such as strength, durability and chemical resistance, the product had to be easy to clean, exhibit a high gloss finish and be aesthetically pleasing.

A variety of concrete floor coatings were considered for this particular project, however, Rhino ArmaFloor 500 was selected for its strength and durability and the products other features and benefits.


All cracks and damaged concrete were repaired prior to being primed with ArmaFloor® 300 ECO. This product was specifically chosen for its ability to bond exceptionally well to existing concrete substrates.

Rhino Linings ArmaFloor 500, a strong durable polyaspartic floor coating used in residential, commercial and industrial applications, was fit for purpose.

This product offers a fast 24-hour return to service, exhibits excellent UV resistance and provided that high gloss finish required by management.

The product was especially suitable for this project due to ArmaFloor 500 excellent chemical resistance against fluids such as skydrol, motor oils, and other hazardous transmission fluids.


Combined, these two products met the required specifications of Qantas Defence Services, including the ease of cleaning, strength, durability, chemical resistance and provision of that aesthetically pleasing and professional look to the hangar floor.

Suffice to say, management was extremely satisfied with the end result.

Concrete Coating Surface Preparation

By the amateur the question is always asked, why is concrete coating surface preparation so important prior to the application of a floor coating system?

Whether you are new to flooring, a specifier, architect or potential customer, understanding the importance of a properly prepared concrete floor prior to the application of an impermeable lining is paramount, especially if it saves you money in the long term. Without correct preparation, concrete coatings will fail resulting in bubbling, blistering and delamination of the lining from the concrete substrate.

Sometimes, the correct concrete coating surface preparation is simply overlooked by both experienced and inexperienced flooring contractors; it may even be the case that the customer wants to cut costs, not understanding the reasoning and importance of correct surface preparation.

To ensure the coating properly adheres to the concrete substrate, a flooring applicator must take into account a number of considerations, which will result in a long lasting, durable, versatile concrete floor coating.


The Concrete Slab

newly laid concreteThe age of the concrete substrate itself can be the first issue especially if newly laid. Concrete is formed by mixing cement, sand, stone and water, as the moisture evaporates the mix cross links leaving hardened concrete in its place.  This curing process normally takes around 28 days, issues arise when coatings are applied to slabs that are still curing, leaving laitance on the surface..  The next issue is excessive moisture.  5 % moisture in the slab is the recommended maximum to which an applicator should be going ahead and coating the concrete slab.  There are tests that applicators can carry out to ensure the moisture content is at an acceptable level and will not cause problems further down the track.  With regard to laitance, this has to be water blasted off the concrete before profiling.


Surface Preparation and Profiling

Concrete PreparationThe third issue is the actual surface preparation.  This is often the most important part of any successful coating or resurfacing application.  The surface profile must be prepared prior to coating, which allows for strong adhesion and reduces the chance of failure.  The NACE  International standard “Surface Preparation and Coating of Concrete” defines a surface profile as “the roughened surface that results from abrasive blast cleaning or power tool cleaning.  For commercial and industrial indoor jobs, shot blasting is another method to prepare the surface. For residential indoor jobs; scrubbing with detergent, acid washing, neutralizing, rinsing and wet/dry vacuuming is another method of surface preparation when mechanical surface profiling is not easily achieved. After profiling, the surface must be clean from dust, dirt, grease or any loose or foreign material that can interfere with bonding.


The Weather & Concrete Coating Surface Preparation

rainy weatherFailure can also occur when a coating is applied under the wrong ambient conditions.  For example, when epoxies either outside or inside are in the curing process they have the ability to draw in moisture caused by high humidity.  Note that humidity should be no higher than 80%, if higher you run the risk of the coating failing.

Tip:  To gauge if a surface is suitable for coating it is necessary to determine the Dew Point, this can be determined by cross-referencing the Ambient Temperature with the Relative Humidity and only lay coatings when the substrate is a minimum of 30C above dew point.

Other issues for coating failures can include:

  • Poor coating thickness
  • Pigments and resins are not blended well enough
  • Abrasion, impact or mechanical damage

Added to the above Murphy’s Law will often apply, if something is going to go wrong, it will go wrong.  Thankfully, if it happens while the coating is being applied you have the ability to correct there and then.

So remember, concrete coating surface preparation is the most important part of any flooring project.  Without it, even the best flooring applicator may experience a coating failure. The cost to repair or replace can be expensive, not to mention the down time involved including customer dissatisfaction  – nobody wants that no matter what line of business you are in.


Adding Colour and Life to Concrete Floors

Concrete Floors are not Cold and Boring

Upon taking a closer look, you will soon find that with the right type of coating a concrete floor can radiate a beautiful contemporary finish that is pleasing to the eye and very easy to maintain.

Concrete floors are extremely versatile

By adding a glossy finish, dyes, acid stains or even the new metallic fusion you can achieve a distinctive and striking effect that will have your concrete floor looking first class all year round and  even more, extend the living spaces in your home.

Many people are seriously considering the versatile range of concrete floor coatings available such as high gloss epoxy, polyaspartic, acid stain and metal fusion for numerous  reasons including:

    • Concrete floors are eco friendly; after all, you are using material already available, just bringing out its natural beauty.
    • Concrete floors are energy efficient;  when used indoors it is surprising to find that concrete will actually hold its warmth  in winter and keep you cooler during those hot summer  months.   You can even save on energy costs if you have an in-floor heating system installed, but that’s another story.
    • Coated concrete floors are dust free and easy to clean;  Allergies are a growing concern for many these days, having a floor covering that is easy to clean, doesn’t harbour allergens  or release harmful chemicals is a necessity .
    • Concrete floors have a prolonged life; Stained floors that are polished and maintained regularly can last a lifetime, and as we know concrete is less vulnerable to damage.

Isn’t it time you thought outside the square when it comes floor coverings for your lounge room,  family room, entrance way, rumpus room, even outdoor entertainment areas?  With a touch of creative imagination, a flooring contractor who considers himself as a bit of an artisan, you too can start enjoying the luxurious richness and colour that acid stain, dye or metal fusion can bring to your home.

Concrete Rejuvenation: The New Interior Design Element

Concrete made a grand entry with the introduction of industrial interior design. It was used as edgy, iconoclastic flooring in cities like Manhattan and Toronto, Vancouver and London. It became a little more mainstream and many Australian homes have adopted concrete for their housing floor of choice. But concrete has many more applications and leading edge designers are using it for every aspect of design from surfaces to furniture.
