Sansin Enviro Stains - Naturally Perfect Wood Protection

For over 25 years Sansin has pioneered the use of environmentally friendly water-borne wood protection technologies that deliver outstanding performance. With a wide range of wood preparation and protection products, Sansin offers solutions for external and internal applications, designed to enhance the natural beauty of your wood.

  • Natural ingredients modified for enhanced performance.
  • Bonds directly with wood rather than forming a film.
  • Forms an integral part of wood's cell structure.
  • Safe for you and the environment.
  • Low odour.
  • Easy to apply and maintain.

The Best of Both Oil and Water

Why choose between an oil or water-based solution when you can have the benefits of both? 

Sansin Enviro Stains combines the two, carrying natural oils and resins deep in the wood's cell structure using water. 

As the water evaporates, Sansin bonds directly with the wood substrate, forming a tough, durable barrier that won't crack, peel or blister.

Wide Range of Choice

Sansin Enviro Stains let the natural personality of your wood shine through. With over 80 colour tones, you can be sure of finding the colour to suit your every project. 

For inspiration, Sansin turned to the everyday miracles of the natural world. 

And should you have a colour in mind that isn't available in our collection, our Precision Coat mixing service lets you bring it to life.


Several companies can claim to be 'green' and friendly to the environment, but Sansin truly lives and breathes their environmental practices, as important now as when Sansin first pioneered the water-based alkyd solution over 25 years ago. 

Natural by design

Sansin's technology is inspired by a thousand-year-old tradition that uses nature's own ingredients - resins and gums from the heartwood of trees - to deliver sustainable protection. 

Low VOC Content

New legislation about Volatile Organic Compound (VOC) content in coatings has forced a wide range of companies to change their formulas to fit within the 152 gram per litre regulations. Caring about the environment from the outset means Sansin's original formulas are as low as 32 grams per litre, meaning it is as safe to use as it always has been. 

No harmful ingredients

Paraffin wax is often used in many water and solvent-based coatings to protect against moisture damage, however, this surface layer can be easily eroded by exposure to UV radiation. In fact, just 5 hours of direct sunlight can reduce water repellency by over 60%* Sansin coatings use no paraffin and contain modified natural oils and resins, impregnated with special UV protectants - so every cell of your wood is protected.

Focus on responsibility

Sansin strives to minimise waste and ensure responsible handling of waste products. A unique rinse water recycling system allows products of cleaning processes to capture and reuse raw materials otherwise waster. Regular facility improvements and operating initiatives such as the Sansin Second Nature programme focus on energy savings, waste reduction and recycling. 

Second nature

Wood is Sansin's passion and their commitment to protecting it and the environment is paramount. Sansin's vision is to continually improve its products alongside their environmental practices, as part of Sansin's Second Nature programme. Sansin is pursuing initiatives such as using alternative green energy, smart car technology, and smart manufacturing processes, moving closer to the objective of operating a sustainable zero waste production facility.
