Penetrating, high performance finish for timber weatherboards.
Sansin SDF provides tough, effective protection for timber weatherboards. SDF’s specially formulated oils and resins penetrate into the wood, providing outstanding weather and UV protection in a wide range of natural, semi-transparent and even solid colours.

Not only is SDF highly water-repellent and protects the outside of your wood, it also protects the inside by allowing the timber to “breathe”, helping prevent moisture from getting trapped in the wood.

This unique waterborne, alkyd formula uses water not solvent to penetrate wood. Precision Coat SDF can rely on a 30-year history of proven durability in an environmentally-friendly formula.

Rosenfeld Kidson & Co. Ltd is a specialist timber company stocking New Zealand’s largest range of over 50 species of specialist timbers, both imported and locally grown.  These timbers are distributed to joiners, furniture manufacturers, cabinetmakers, boat builders, flooring contractors and the construction industry throughout the country, primarily via selected timber merchant resellers.

The company was incorporated in 1930 when John Kidson and Australian Julius Rosenfeld formed a partnership to import hardwood from Australia.  New South Wales hardwoods were in demand during the depression years for wharf and bridge construction, as well as power reticulation.

For the next 65 years the company operated from The Strand in Parnell, Auckland, before moving in 1996 to new purpose built premises in Mt Wellington - an 11,000m2 site with 2000m2 drive-through warehouse and another 1000m2 of covered storage. The business also operates a second 2500m2 site in Auckland where its state of the art timber processing facility is located. It also has a second sales and warehouse facility in Hornby, Christchurch, which manages distribution to our South Island customers.

As Rosenfeld Kidson approaches 90 years in business, the company is in its fourth generation of ownership and operation.  The success and longevity of the company has largely hinged on the efforts and experience of dedicated and loyal staff, who are able to provide our customers with a wealth of knowledge about the specialist timbers we sell.
