Sansin Foundation: Penetrating base coat that improves topcoat performance.

Penetrating base coat that improves topcoat performance and lightens wood.

Sansin Foundation is a penetrating first coat alternative for light-colored wood when looking to avoid the red/yellow/brown wood tones. Foundation also offers up to 6 months of complete aggressive UV without color additives for the construction phase. Even better, it dramatically enhances topcoat performance without extensive preparation – simply wash and apply the appropriate product over Foundation as directed. Available in three tones: lightwood, fir and cedar.

Foundation is perfect for both interior and exterior wood surfaces like timbers, logs and lumber. It penetrates naturally, carrying solids deep into the wood where they form a monolithic bond with the wood tissue. This increases dimensional stability, reducing checks and wood movement. In addition to protecting against harmful UV radiation, it enhances the natural moisture resistance of wood surfaces without causing adhesion issues for subsequent topcoat applications. When it comes to protecting wood, Sansin Foundation is simply the best way to start.

SDF Foundation and Classic Foundation formulas available.
