Sashco Colorfast

Colorfast™ strengthens the glue that binds the wood cells together, called lignin, preventing yellowing of the underlying wood cells to help maintain a consistent color year after year. Before staining, Colorfast™ evens out wood porosity, creating a smoother surface for stain application and preventing over-absorption and a too-dark color. After staining, the lignin stabilizers prevent the wood underneath from getting sunburned, leaving the stain applied on top looking the same year after year. Colorfast delivers the ideal canvas for stain application and leaves behind the strong foundation necessary for long-lasting color.
