Decks & Exterior Protection

Exterior protection for siding, decks, furniture and millwork.

Should you protect your wood home with a water or an oil-based coating? With Sansin’s line of Exterior Enviro Stains, you can have the best of both worlds. Modified natural oils and resins are carried deep into the wood’s cell structure using one of nature’s commonplace miracles – water. As the water evaporates, Sansin bonds directly with the wood substrate, forming a tough, durable barrier that won’t crack, peel or blister.

Sansin’s unique formulas offer every possible level of finish – from penetrating natural finishes, to high-gloss barrier coatings, you can match the look of your Enviro Stain with the protection your project needs.

No matter which Sansin exterior product you choose, you can count on exceptional beauty and lasting performance.


Wood is a tremendously versatile material – and as long as it’s protected, a strong and durable one. Water, ultraviolet (UV) rays and fungi can all seriously damage your wood exterior. Sansin’s penetrating formulas let wood “breathe“ more freely, improving dimensional stability and allowing wood to adjust naturally to moisture levels in the environment. Sansin forms a monolithic bond with your wood that aggressively repels condensed water while allowing moisture vapor to escape.For barrier coat applications, Sansin offers high-build formulas that lock out moisture and offer maximum UV protection. The paraffin waxes that protect against water in many water and solvent-based coatings are easily damaged by exposure to UV radiation – just 5 hours of direct sunlight can reduce their water repellency dramatically. Sansin’s modified natural oils and resins are impregnated with special UV protectants so every exposed cell of your wood is protected. Because of their unique formulation, Sansin Enviro Stains also help protect naturally against wood rot.
