Sansin Stain – The Natural Choice for Wood Protection

Sansin Stain is trusted across North America by homeowners, contractors, architects, and preservation specialists. Known for high-performance protection and beautiful, long-lasting finishes, Sansin offers a complete range of environmentally friendly wood coatings designed to preserve the beauty and integrity of wood in even the most demanding environments.

Whether you're finishing a new log home, maintaining heritage siding, or protecting exposed timbers and decks, Sansin's innovative Enviro Stain technology delivers professional-grade performance with minimal environmental impact.

What Is Sansin Enviro Stain?

Sansin Enviro Stain refers to the brand’s entire line of water-borne wood protection systems, formulated using modified natural oils suspended in water. Unlike conventional coatings that trap moisture or rely on heavy solvents, Enviro Stains penetrate deeply into the wood, allowing it to breathe while resisting water, UV, and fungal damage.

Enviro Stains are designed for:

  • Log homes and timber frame buildings
  • Siding, shingles, and soffits
  • Decks, fences, and railings
  • Exposed beams, posts, and wood trim
  • Interior wood applications

With low VOC emissions, deep color saturation, and outstanding longevity, Sansin’s Enviro Stains deliver both performance and peace of mind.

Why Choose Sansin Stain?

  • Advanced Water-Borne Technology: Uses water instead of harmful solvents for better penetration and reduced environmental impact.
  • Deep Penetration: Soaks into the wood rather than sitting on top, minimizing peeling and flaking.
  • Natural Oils Modified for Durability: Engineered for long-term performance with renewable resources.
  • Low VOC Formulas: Safe for indoor use and eco-conscious construction.
  • Breathable Finish: Prevents moisture entrapment and supports natural wood drying.

The Sansin Story – Built on Innovation and Sustainability

Founded in 1986 in Ontario, Canada, Sansin began with a mission to develop environmentally friendly wood coatings that didn’t sacrifice performance. Today, they lead the industry with advanced Enviro Stain systems trusted in both residential and commercial projects.
