It forms a breathable, penetrating barrier that completes the system and ensures your home stands up to extreme weather, UV exposure, and moisture cycling.Unlike traditional surface coatings, Classic 3 bonds with the prior layers to maintain flexibility while repelling water and allowing vapor to escape. It enhances the depth of color, adds subtle sheen, and seals the wood for lasting beauty and resilience. Ideal for use on both new and restored log buildings, this topcoat completes the breathable system designed to move with your home—not against it.What Makes Sansin Classic 3 Unique?Classic 3 isn’t just a topcoat—it’s a sealing finish that reinforces the Sansin Classic system. Engineered to penetrate and bond with Classic 2, it creates a cohesive outer layer that repels moisture while allowing logs to breathe. It’s flexible enough to expand and contract with the wood, reducing the risk of cracking or peeling over time. Classic 3 brings out the richness of color and provides a low-lustre finish that enhances the natural look of the wood.Key Benefits of Classic 3Final step in the breathable Sansin Classic 123 system.Enhances water repellency and UV durability.Flexible and breathable—will not trap moisture.Reinforces color depth and adds visual richness.Low-lustre finish enhances wood grain visibility.Penetrates and bonds to Classic 2 for long-term adhesion.Application NotesSystem Use: Classic 3 must be applied after Classic 2.
