Sansin SDF: A penetrating finish for exterior or interior wood surfaces.

A penetrating finish for exterior or interior wood surfaces.

Sansin SDF provides tough, effective protection for wood siding. SDF’s specially formulated oils and resins penetrate into the wood, providing outstanding water resistance and UV protection in a wide range of natural, semi-transparent and even solid colors. Thanks to SDF’s unique water-borne technology, it provides complete protection in 2 to 3 coats depending on your choice of maintenance cycle and finish, for added durability SDF Topcoat is used for the second and optional third coat for an even richer, satin finish. When the timeline is tight, SDF can be applied as a 1 coat matt finish, in this case it is recommended to adequately pigment the product. Consider doubling the tint load of the first coat of SDF for adequate tone and protection.

And because SDF is designed to be highly water resistant for wet climates, it’s a natural choice for homes and structures in moisture-rich environments. Not only does SDF protect the outside of your wood, it also protects the inside by allowing the wood to “breathe” which helps prevent moisture from getting trapped in the wood and causing rot.

SDF is rated by siding manufacturers as one of the best Naturals finishes available.
