Additional Uses

Duram EP S100 can be used for high traffic, chemically demanding, anti-staining areas.


The information contained in this product data sheet is typical but does not constitute a full specification as conditions and specific requirements may vary from project to project. The instructions should be considered as a minimum requirement but the applicator or contractor must use their skill, knowledge and experience to carry out additional works as may be necessary to meet the requirements of the project. Specification for specific projects should be sought from the Company in writing.


Avoid applying  when relative humidity is greater than 80% and temperature is below 12ºC.

The product should only be used by a person suitably experienced and skilled in applying epoxy (2 part) products.
Product mixed off ratio may result in the non-curing or improper curing of the product and will certainly diminish or negate the performance of the product.

Texture and Profile of the Product
The finish, profile and appearance of the product may vary dependent upon the size, porosity, strength and type of aggregate and the finish of the concrete. On sound surface the range of variation can be controlled and/or limited to closely resemble the referenced CSP standard. As the depth of removal increases, the profile of the substrate will be increasingly dominated by coarse aggregate.

Priming and Surface Preparation

Good preparation is essential. Surfaces must be sound, stable, dry, clean and free of dust, loose, flaking, friable material and substances that may diminish adhesion.


Good and proper surface preparation is essential for a successful project.

• Concrete must be at least 28 days old, dry and free of curing agents, oils, grease, dirt, dust and contaminants.
• Drummy, friable, loose, weak and doubtful concrete should be removed and then made sound using a suitable high density, high strength mortar. Allow to properly cure.
• If contaminated, then clean with industrial strength heavy duty degreaser the thoroughly flush. This process may need to be repeated.
• Remove laitance, best by mechanical abrasion (grinding) to exceed CSP 3 Standard.
•If this is not possible then aid etch (50:50 hydrochloric acid: water), then apply at about 2m²/Lt and allow this to react for approximately ten minutes. Apply an acid neutralising base then thoroughly flush with water, allow to dry,then scrub with a stiff brush/broom to remove loose material.

Timber and CFC
• Surfaces must be dry, free of  oils, grease, dirt, dust and contaminants.

Prepare steel surfaces in accordance with AS 1627-2002.

Painted Surfaces
• All paint must be removed. This can be done by using a paint stripper, degreaser / cleaner then grinding or sand-blasting to a bright metal finish.

Note: As good preparation is vital, the surfaces should be checked for preparation adequacy before proceeding with the application. 


Detailing Preparation

• Add colour pack to Compound (resin component). This mix is stable and can be stored indefinitely.
• Add hardener to the above mix in the correct volumetric ratio.
• Mix only sufficient material that can be easily applied within 25 minutes at normal temperatures of between 20ºC and 25ºC.
• Mix thoroughly using a mechanical stirrer at low speed (>400 rpm). Ensure that the sides and bottom of containers are scraped so that all material is thoroughly mixed.
• Avoid air entrapment.

Mixing Ratio
• Mix by volume in the following ratio. 3 parts resin (incorporating the colour pack) to 1 part hardener.

Note: It is critical that the product is mixed in the correct ration. Deviations may result in non or improper curing and the diminution and negation of the product's performance. 


Site Review
• Ensure that the area has been correctly prepared.
• Ensure that the correct fixed volume of product is at hand can be applied to over the area at the correct application rate.
• The product mixing area should be isolated from the application area, and care should be taken that unmixed products or spills do not contaminant the area.

• Using a slow mechanical mixer (400rpm), thoroughly mix the colour pack in to the resin component them add the hardener component and mix until homogenous. Sides and bottoms of containers should be scraped to ensure that all product is properly mixed.

Apply at least two coats  by roller or airless spray to achieve a final 300 micron dry film thickness. The first can be diluted (if required) up to 20% with Duram Solvent to promote easier working. If Duram Solvent is used then it is important to ensure that all solvent has evaporated before applying the next coat.
If more than 24 hours ave elapsed between coats, the first coat should be abraded to a uniform dull finish with all dust and lose material removed.

The select aggregate should be broadcast in to the first wet coat. Any excess aggregate should be brushed away and then a top coat should be applied.

Optional Clear Coat
A coat of Duram EP S100 Clear can be applied for additional glass and ease of cleaning.


The stated average coverage rate may vary depending upon type, condition, porosity, texture of the surface and application technique.


Approximately 4m² to 6m² per Lt per coat, usually applied in two coats.

Estimating Usage
8   Lts covers 24m² @ 160 microns dry film thickness per coat. Final DFT is 320 microns.
16 Lts covers 48m² @ 160 microns dry film thickness per coat. Final DFT is 320 microns.
