Coverage will vary depending on type of wood, age and surface structure.

Maintenance Cycle

If the wood surface is exposed because of damage, decide whether to repair the complete board or spot repair. In either case, clean the surface to remove contamination and allow to dry. Follow with sanding to smooth the surface appropriately then apply the same coating schedule to match the initial application.

For proactive maintenance coats, gently wash the surface and remove all contamination by an agreeable method being careful not to over wet the surface. Allow the surface to dry completely. If necessary sand using a 220-320 grit paper. Apply a maintenance coat using an appropriate applicator. See directions for further details.

How frequently maintenance coats are required will depend on the quality of prior preparation, quality of application and exposure levels.

Sansin Enviro Stains - Naturally Perfect Wood Protection

For over 25 years Sansin have 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 offer solutions for external and internal applications, designed to enhance the natural beauty of your wood.

Why choose Sansin?

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

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 sing 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.

News - Silva Timber becomes UK Distributor of Sansin Enviro Stains


Several companies can claim to be 'green' and friendly to the environment, but Sansin truly live and breathe 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 forumulas 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 an contain modified natural oils and resins, impregnated with special UV protectants - so every cell of your wood is protected.
