Oxy-Klenza™ for External Sandstone from Dry-Treat

The Project:

McMahons Point in Sydney is known for its proximity to Sydney Harbour and all that it offers. On the downside, it is exposed to air-born salts from the harbour.

At this newly-renovated apartment building, the exterior sandstone required cleaning before being sealed.

Oxy-Klenza ™ plus pressure washing was the method of choice for cleaning, followed by STAIN-PROOF™.

Special Requirements:

There were a number of stringent prerequisites for choosing a cleaner and sealer for the external standstone on this project:

1) Cleaner must designed for natural stone
2) Environmental choice
3) Sealed surfaces should be easier to maintain and clean - withstanding commercial cleaning processes and alkaline cleaning chemicals
4) Superior water and oil stain repellency
5) The look and finish of the surfaces had to be retained

Dry-Treat Solution:

The cleaning process of the exterior sandstone wall required a combination of:

- Oxy-Klenza™ formed into a paste to apply horizontally; and - Pressure washing

From an environmental viewpoint, the unique odourless technology of Oxy-Klenza™ is safer to use than traditional chlorine based cleaners. Oxy-Klenza™ decomposes quickly into oxygen, water and natural salts, making it the better choice for the environment.

Oxy-Klenza™ can perform a range of cleaning including grease, mould, algae and leaf marks on a wide range of surfaces such as patios, public areas, swimming pool surrounds, driveways, eating and entertaining areas.

Once clean, STAIN-PROOF™ was chosen, with particular importance on protecting against water and air-borne salts coming from the harbour. Surrounding trees and other vegetation also meant that stains from leaves would also have to be cleaned off easily.

STAIN-PROOF™ bonds permanently inside the pores by a process of chemical reaction, actually becoming part of the molecular structure of the treated tile. So STAIN-PROOF™ does not have to be re-applied regularly. A 15 year performance warranty is available when a surface is treated with STAIN-PROOF™ by an accredited applicator.
