Small (1/4 in. = 6.35 mm)
Large (1/2 in. = 12.7 mm)
Extra Large (1 in. = 25.4 mm)


Existing tiles need to be cleaned using suitable detergent. After cleaning, the tiles need to be grinned with diamond grinder machine to roughen the surface. All existing tile joints need to be filled and levelled with Primer. Old, loose, broken and brittle tiles and tile joints need to be removed and replaced with epoxy mortar-quartz mix using binder mixed with quartz using a resin: quartz sand mixing ration of approximately 1:9.


Priming the substrate

Mix the components of Primer with a low-speed mechanical stirrer until a homogeneous mix is obtained. Add the Color Paste and re-mix until homogeneous. Apply onto the substrate using a brush or roller at a consumption of approximately 0.30 – 0.50 kg/m2 and let it reach touch-dry condition.


Application of the basecoat and Flakes

Mix the components of floor with a low-speed mechanical stirrer until a homogeneous mix is obtained. Add the Color Paste and mix until homogeneous. Apply using a roller at a consumption of approximately 0.20 – 0.30 kg/m2. While the basecoat is still wet, broadcast the flakes over the surface (the amount of flakes to be broadcast will depend on the desired finish).

Let it cure for 12 – 16 hours at 30 degree. Scrape the surface of the flakes using a metal scraper and remove all loose and unbonded flakes. Lightly sand protruding flakes to ensure an even surface.


Application of the sealing coat

Mix the components of floor until a homogeneous mix is obtained. Apply 1 coat using a roller onto the flakes and allow to dry for 6 hours at 30 degrees.


Application of the finishing coat

For a textured gloss finish: Apply 1 coat of floor using a roller onto the flakes. Allow to dry for 24 hours.

For a textured matt finish: Apply 1 – 2 coats of floor (observe overcoating interval of the product). Allow to dry for 24 hours.

For a smooth gloss finish: Apply 1 mm self-levelling coat of floor. Allow to dry for 24 hours.

For a smooth matt finish: Apply 1 mm self-levelling coat of epoxy floor and allow to dry for 24 hours. Lightly sand the surface and apply 1 – 2 coats of Floor Finish (observe overcoating interval of the product). Allow to dry for 24 hours.


Wall application

Apply the epoxy flakes system on walls the same procedure of floor application.



Typical consumption of the Epoxy Flakes is 0.4 – 0.8 kg/m2; the actual consumption will depend on the size of the flakes used and the degree of flake density of the desired finish.



Available in 5 kg boxes.



Store in its original unopened packaging in a dry place.


Safety Instruction for preparation and application

Epoxy flake is an article and referring to the current regulations does not require the preparation of the material safety data sheet. During use it is recommended to wear gloves and goggles and follow the safety requirements of the workplace. Product for professional use.


Typically for a toilet floor, it would take 1 day for complete installation. (Half day installation, another half day drying period) As for toilet wall and floor, it would take about 3 days for complete installation.

No, the epoxy top coats are non yellowing.

1 year limited warranty is provided against peeling, staining and material flaws. No warranty is given for cracks and other damage caused by the shifting of the substrate underneath the surface.

We always repair all the cracks and pits of your floor, before installing the epoxy coating.

Yes, an epoxy floor is very strong and durable, but can be damaged by mechanical force or if the substrate or concrete floor below is damaged. Dragging a heavy object with steel legs across it, for example, would be damaging. An epoxy floor can succumb to scratching like ordinary concrete is but properly looked after it can be exceedingly durable and will last many years looking beautiful.

The grinding system we use creates no dust and we do not leave a mess after completing our job.

Depending on the coating system used, most installations are completed in 3 days.

A broom or a leaf blower can be used for light cleaning. Mild soap and water applied with a mop is perfect for deeper cleaning.

From experience, you should be able to walk on the epoxy floor surface in 24 to 48 hours. The surface is good for driving on within 7 days. It may take shorter or longer depending on the time of year and range of temperature.

Yes. Epoxy flooring can be applied to floor surfaces of patios, sidewalks, breezeways, porches and steps.

We can use a flake floor system that makes the floor no more slippery than standard concrete when wet. A flake system floor gives a texture feel to it and is normally no more slippery than regular concrete when wet. With a smooth solid colour we can also add slip resistant additives to the topcoats that makes the floor less slippery.

While Table 2 lists the three principal Australian pedestrian slip resistance standards, architects and should only need to be familiar with Standards Australia Handbook 197, An introductory guide to the slip resistance of pedestrian surface materials. This deals with the selection of products based on the wet slip resistance classifications that are obtained according to the test methods that are published in AS/NZS 4586, Slip resistance classification of new pedestrian surface materials. HB 197 was also written to help with the transition from AS/NZS 3661.1, Slip resistance of pedestrian surfaces -Requirements. The major differences are summarised in Table 3. Some important implications of AS/NZS 4663, Slip resistance measurement of existing pedestrian surfaces.

AS/NZS 4586 introduced the ramp tests due to concerns about the suitability of the pendulum for measuring the slip resistance of highly profiled surfaces and resilient materials. The relevance of walking on a ramp to walking on

the level has been questioned, recognising that a natural gait pattern becomes different at high slopes. However, the intention is to reliably determine the available traction, rather than to replicate a walking-onthe­level gait. Very short half-steps are used during ramp tests, because

the coefficient of friction is a function of the step length. Such testing yields a measure of the available friction of the test surface when it is installed as a horizontal floor. The tangent of the critical ramp angle gives the available coefficient of friction of the tested shoe-bottom/floor-surface combination

when used on a level floor.

Dry floor friction test results of new stone tiles are of dubious value, as there is no contamination, unlike the real world. Clean Four S rubber tends to adhere to very smooth flat surfaces such as float glass, due to a very high degree of contact between the surfaces. The measured

coefficients of friction on such surfaces are significantly higher than rougher surfaces that provide far greater traction when there is some form of dry soiling. Although pedestrian surface materials are classified according to the dry floor friction test, there is no notional interpretation of each class. While there are very few new pedestrian surfaces that would have a dry mean coefficient of friction of less than 0.4, they would make a high contribution

to the risk of slipping. However, it would be inappropriate to assume that all products that have high coefficients of friction would make a very low contribution to the risk of slipping when dry.

Notional interpretation of wet pendulum classes

W 45 — 54 40 – 44 Low
X 35 — 44 Moderate
Y 25 — 34 High
Z <25 Very High


The most common form of slip resistance testing in Australia is the wet pendulum test. The associated classifications (Table 5) are used for classification purposes (Table 6). There is an obvious need to fill in the blanks in Table 5, since one should be able to classify a product after it has been tested. However, when products are tested with both rubbers, a

significant scatter of results occurs. When potential classification boundaries are considered, the correlation is poor. This provides evidence that the

type of soling material has an influence on the slip potential.

Transport authorities measured the skid resistance of roads using the pendulum with TRRL rubber before it was widely used for measuring

slip resistance. This led to the brick paver and concrete paving industries adopting TRRL rubber. Four S rubber was developed later for measuring the slip resistance of marginal internal floor surfaces. Manufacturers were expected to use one rubber or the other for testing their products, as

appropriate for their primary market. The initial withholding of classes X,

Y and Z has forced some manufacturers to use Four S rubber. Recent CSIRO research suggests that TRRL rubber provides a better indication of wet barefoot slip resistance than Four S rubber, so some manufacturers might elect to test with both rubbers.

If one presumes that the interpretation for new products includes a factor of safety allowing for some loss of slip resistance (in the more slip resistant products) with time, then there are some potential difficulties in applying the same interpretation to existing surfaces. However, these notional interpretations were intended to be indicative rather than definitive.

able 6 includes both pendulum and ramp classifications. If one regards slip resistance results as being indicative, and recognises the probability that some results will underestimate or overestimate the available friction, then it is easy to appreciate the benefit of relying on two methods of classification rather than one. It is quite possible to get a product that has X and R9 or Y and R10 classifications, but a product with X and R10 classifications is likely to perform better than some that are selected just on the basis of an X or an R10 classification. Since slip resistance test methods have inherent limitations, some test methods will be more appropriate for specific circumstances. For instance, since rubber is a poor surrogate for human skin, the wet barefoot ramp test should provide the best indication of slip resistance for areas such as bathrooms.

Table 3 of HB 197 provides basic guidance, which might be considered

as recognised best practice. The text indicates that some recommendations may be onerous and others lenient, and draws attention to other design factors that architects should consider. The handbook thus permits variations (probably one class), which should be based on either

existing practice/experience or considered reasoning, logically based on an appropriate risk minimisation strategy. Tables 4 and 5 of HB 197 report the more detailed German requirements, and Committee BD/94 cannot modify these.

The HB 197 recommendations do not cover all locations, for instance, balconies. The handbook was not intended to outlaw products that have a track record of successful use in specific locations. Individual manufacturers (or importers or retailers) may make claims about the suitability of specific products for particular applications. It is up to architects to assess individual situations to determine what other design considerations apply (i.e., they should read clause 3 of HB 197). Given knowledge of products that have been traditionally used to fulfil a function, the architect can specify products they consider appropriate. If they choose not to comply with the HB 197 recommendations, it would seem sensible to document the basis for their selection.

There may not be a lot of difference in the slip resistance of a product at the top of the R11 classification and another product at the bottom of the R12 classification, but there is a significant difference in performance between products at the bottom of the R9 and the bottom of the R10 classifications. Unfortunately too few manufacturers publish the actual mean corrected angles. Tables 7 and 8 give the angles that pertain to each classification.

Table 8

Classification of pedestrian surfaces according to the wet oil ramp test

Classification Angle (degrees)
R9 3.0 — 10.0
R10 10.1 —19.0
R11 19.1 —27.0
R12 27.1 — 35.0
R13 35.0


The wet barefoot ramp test is technically equivalent to DIN 51097. The actual classification is dependent on the angles attained on the calibration boards, which have nominal angles of 12, 18 and 24 degrees. If the walkers obtain an angle of 26 degrees for the C board, the walkers have to obtain an equal or better result in order for a product to receive a C classification.

The oil wet ramp test is technically equivalent to DIN 51130. Despite this, CSIRO has been unable to obtain some of the ramp classifications

that have been accorded to some imported products. Since batch-to-batch variations occur, consumers are advised to test a representative sample, particularly on large projects. The question of whether to recognise foreign results is considered in

A few products have been tested that have a corrected mean angle of less than 3 degrees. Such products should be suitable where class Z and R9 products are recommended for dry locations.
