Sansin announces KP-14, a new vapor permeable barrier coating for wood

Strathroy, Ontario, Canada – May 30, 2024– The Sansin Corporation has developed environmentally friendly, high-performance wood protection for more than 35 years and today announced the launch of KP-14, a vapor permeable barrier coat for wood. Part of the company’s Precision Coat Factory Finish Line, KP-14 can be applied to engineered wood components like CLT to protect aggressively from moisture absorption.

KP-14 is designed as a moisture protection plan in conjunction with KP-12W for the exposed top sides of CLT panels. This system aggressively protects wood from water absorption while maintaining vapor permeability similarly to bare wood according to EN927-5 and EN927-4 moisture absorption testing. The KP-12W / KP-14 system offers vapor absorption desorption efficiency of 89% comparable to 92% efficiency of bare wood. This distinguishes KP-14 from other membranes that may entrap the water, possibly leading to mold growth, wood rot and decay.


KP-14 is highly durable, and like most Sansin products is water-borne and low in VOCs. KP-14 is a clear coating and can be field or factory applied to the necessary level required to protect the wood and prevent weathering and water absorption during installation phase.

“Architects, engineers, and mass timber builders are committed to creating the best looking, longest-lasting wood and mass timber buildings possible. They are often plagued with moisture management challenges on job sites that can be extremely wet,” said Sjoerd Bos, Sansin’s Managing Director. “KP-14 holds water out similarly to a traditional rubber membrane, while costing a fraction of the price.”
