KP-12 by Sansin is a water-borne, low-VOC penetrating wood treatment developed for the protection of solid and engineered timber, including CLT and glulam. Applied cold and typically factory-finished, the product penetrates the wood fibres to provide moisture resistance and dimensional stability while preserving the timber’s natural appearance, rather than forming a surface film. Its formulation supports the long-term durability of exposed wood elements and can be used as a preparatory treatment beneath compatible finishes where required.
As a water-based product with low volatile organic compound content, KP-12 aligns with indoor air quality considerations and broader sustainability objectives by reducing emissions during application and use, while supporting the longevity and reuse potential of timber components over the building’s life cycle.
