The difference between dirty, cleaned and sealed Oamaru stone
The unsealed natural stone absorbs water, becoming heavy, wet and mouldy.
Our environmentally friendly cleaner, kills and removes mould, preparing it for sealing.
The sealed stone now breaths & beads water, allowing it to dry out for a healthier, drier home.

Frequently asked questions about Oamaru Stone
What is Oamaru Stone?
Oamaru stone, sometimes referred to as Whitestone is actually a compact and hard form of Limestone, and is quarried out in Weston, near Oamaru in central Otago, New Zealand. Like Hinuera stone, Oamaru stone is soft and porous material, allowing it to absorb water and moisture.
Oamaru stone started to become gain popularity around New Zealand after the mid 1960’s, as it was primarily only used in Oamaru before then.
It is considered a very prestigious stone and has been used on some very iconic building around New Zealand including, The Auckland High Court, Government House, the Christchurch Arts Centre and the Otago University.
Since Oamaru is a soft porous stone, it is often used for internal features and sculptures as it was easy to shape and carve.
Do I need to get my Oamaru Stone cleaned?
If your Oamaru stone is showing signs of black, pink or orange mould, lichen and green growth, and generally wall to wall discolouration and losing its natural look, then yes, it needs cleaning.
A good indication of what your Oamaru stone originally looked like, is to inspect the top ¼ of a wall under your soffits or in a protected area. For example, at the front entrance or walls that are not exposed to the elements.
If you are building a new Oamaru stone home, it is just as important to clean it before it is sealed. In the process of the house being built, the Oamaru stone should be protected with temporary downpipes. Dirt and building materials should be kept away from the bottom course of the Oamaru stone. During the build a lot of dust settles on the pointing and the face of the Oamaru stone. If this is not removed, it will leave streaking and uneven discolouration during the sealing process.
Do not waterblast your Oamaru stone. It is a soft porous stone and the high-pressure water will damage and pit the surface of it. Contact us for a free assessment and general check-up of your Oamaru stone.
Do I need to get my Oamaru Stone sealed?
Yes. It is very important to seal your Oamaru stone.
For existing and new builds, sealing your Oamaru stone home provides the stone with a protective coating that enables it to breathe, but stops the penetration of water. This also allows the stone to retain is natural characteristics.
Sealed stone keeps the Oamaru dry, preventing mould and lichen to take hold. Providing you with a drier, warmer and healthier home.
Do not attempt to seal your Oamaru stone yourself. It is a specialised process and done incorrectly, you can cause irreversible damage to your home.
