About Discrete

Discrete And The Environment

  • Discrete - is an advance in the chemistry of removing cement and grout residues from concrete mixing and transportation equipment, newly laid tiled flooring and a variety of surfaces affected by cement splash on the construction site.
  • It has been developed to overcome the traditional hazards associated with the acidic solutions normally used to remove cementicous based residues on metals.

Discrete Chemical Make-up

  • A low pH organic salt blended with biodegradable wetting agents. Discrete is based on acid-replacement technology and although low in pH does not contain traditional acids such as Hydroflouric, Hydrochloric, Sulphuric, Phosphoric, Nitric, Citric, Sulphamic, Oxalic and Glycolic.

How does it work?

  • This proprietary formulation uses newly researched acid-replacement technology where the organic salt, being low in pH, acts like an acid in the cleaning process but has none of the characteristics associated with acid cleaners. This provides the user with all the cement residue removal power they need without the associated dangers of using an acid such as acid burns, fuming and dangerous goods transportation and storage.


  • Discrete displays a dramatically improved corrosive profile to traditional acid cleaners in respect of both ferrous and non-ferrous metals. When used as directed, negligible corrosion occurs and even when used undiluted the level of corrosion to ferrous metals is almost undetectable. However, it should be remembered that Discrete is a low pH and corrosion will occur on metals subjected to Discrete for extended periods.

How To Use

  • Dilute 1 part Discrete with 4 parts water and spray or brush apply to the surface being cleaned. Allow approximately 10 minutes dwell time and rinse well with a high pressure washer or hose.


  • Discrete is classified as a skin irritant in it’s concentrate form, and is classified as non-hazardous for transport according to the Australian Dangerous Goods Code. This “non-DG” classification also means less regulated storage of Discrete on construction sites and industrial warehouses.
  • Whilst Discrete displays a very low hazard profile for the user in terms of it’s effect on skin , eyes and respiratory system it is recommended to always wear eye protection and gloves to minimize exposure to cement residues and prolonged contact with Discrete.

Biodegration and Aquatic Safety

  • Discrete is readily biodegradable, phosphate free and does not contribute to the eutriphication of waterways.

Waste Water Systems

  • Discrete has very low COD and BOD levels making it an excellent choice for where waste water processing systems are used. It is however, recommended that pH readings be taken to ensure that waste water pH readings comply with water board recommendations.

Discrete And Acids

  • Cement as a chemical is strongly alkaline (pH over 7) and is only effectively dissolved and removed using a low pH (pH less than 7) solution. Technically speaking a substance with a pH over 7 is regarded as an alkali and a substance having a pH less than 7 as an acid.
  • Acids used in the cement removal industry have had negative characteristics and although they have generally worked well, the adverse effects on the environment, health and substrates have been an ongoing concern
  • Modern technology has enabled us to overcome these negative issues by replacing these traditional acids with an organic salt which has the low pH required to dissolve acid but does not carry the same adverse effects on the environment, health and substrates.

So Can Discrete Be Classified As An Acid?

  • No, it has a low pH (technically making it an acid), but does not fit into the definition of an acid, when defined as per the effects and characteristics of acidic solutions.


  Discrete Acids (eg Hydrochloric, Phosphoric)
Environment – COD levels aprox 3500mg/L between 1,000,000 - 2,000,000mg/L (organic acids)
Environment - Biodegrability Biodegradable Varies with some acids causing eutraphacation & low biodegradability
Health – Toxicity Skin irritant Corrosive to skin
Health – Respiratory Low (non fuming) Repugnant fuming
Corrosion To Ferrous Metals Low Hydrochloric causes pitting and staining


  • These unique features make Discrete the ideal alternative to acid based cleaners.
  • When disposed of, it should be noted that to totally eliminate any negative impact on water ways the pH of the waste water should be adjusted to 7 to 8.
