Everything that has been created in nature has proportion, ratios, harmony and balance. The very essence of beauty and perfection. These are the principles that are used by Bernie and Summer Koker at Constantia. The magnificence and perfection of their timber creations is unsurpassed . I have been using their incredible products in my furniture restorations for over 40 years with complete satisfaction.

We have been using the Chinese oil on the steel and timber on our boats for over 13 years. It is the most durable product we have found against the sea and salt air and the easiest to maintain.

Design & Technology Teacher, Tumby Bay Area School

Tumby Bay, South Australia

My students often choose to use Chinese Wood Oil on their quality timber projects. Of course, the beautiful look and feel of the finished job is the main factor in their decision but also the ease of application and its low toxicity makes the job easier for all of us! Over the years, Summer has been extremely helpful in providing advice to my students and me regarding the range of excellent finishes and their application methods. Constantia is a great company to deal with for top quality and impeccable service.

Christine Tuckwell

I remember my father using Constantia products on all his woodwork projects when I was a child. They were always a brilliant product and gave a beautiful long lasting finish to the timber he used. I still have some of those items and they look and feel as good as new.

I was so pleased to hear that Constantia was still in business after all these years when I was looking for a product to give new life to some of my furniture.

I would highly recommend the Constantia name and product for all timber items.

Doris Lush

I have been using Chinese Wood oil and Red oil for 21 yrs +.The wood oil is easy to use and gives an enduring natural finish to the timber. I often use red oil as a first coat to enhance the grain. When pieces need a touch up over time I rub them over with very fine steel wool and then re-apply the required coats of Chinese Wood oil.

Keith Daniels, Master Builder

I have used Constantia finishes throughout my boat. The products are pleasant and easy to use and have held up well against the elements. Maintenance is minimal.
