Finishing & Protection

It is recommended that a finish is applied to all surfaces, including ends, before installation. The type of coating will be determined by the final finish and appearance desired.

Why Pre-finish?

  • Enhances the natural beauty of wood
  • Ensures a consistent finish
  • Applied in factory conditions
  • Long lasting protection against weathering
  • Simple maintenance routine
  • Reduces onsite labour costs

Prefer the silvery-grey look?

Sioo Impregnation quickly provides a clean wood surface with an attractive silvery-grey finish often desired but seldom achieved from new wood or damaged applications.

What is weathering?

There is a risk involved when leaving wood exposed to the elements. During the weathering process wood can appear unsightly as the material can blacken due to moisture getting into the fibres and pulling out tannins and extractives. Finish protects the wood from moisture absorption and UV degradation.

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.
