Nothing protects wood outside like Sansin Classic. Classic was originally engineered to protect log homes, with a three-coat penetrating formula that repels condensed water while allowing water vapor to escape. Not surprisingly, Classic works just as well on other exterior vertical surfaces, like shakes, shingles, siding and fences. Your wood will be protected with an ultra-violet (UV) and water-repellent shield of lasting and remarkable beauty. Classic is available in the full range of Sansin colors, and like all Sansin products is distinguished by ease of application and maintenance.
