Sansin DEC Topcoat
Durable Topcoat Finish for Enhanced UV and Water Protection
Sansin DEC Topcoat is a high-performance, water-borne finishing treatment designed to be applied as the final coat over Sansin DEC. Engineered to deliver a fuller, more protective finish, DEC Topcoat enhances color retention, resists UV degradation, and extends the lifespan of horizontal wood surfaces like decks, balconies, and fencing. Its breathable formula forms a durable, non-film-forming barrier that repels water and protects against cracking, peeling, and blistering.
What Makes Sansin DEC Topcoat Unique?
DEC Topcoat forms a monolithic bond with the Sansin DEC system, improving water repellency and UV resistance without trapping moisture. The result is a clear or translucent finish that resists environmental wear while showcasing the natural beauty of wood. Whether used for Natural or Translucent tones, DEC Topcoat stabilizes color, smooths surface texture, and increases durability against foot traffic and seasonal exposure. Tintable base options offer additional UV protection and color enhancement.
