KP-14+ is a 1-coat formula that replaces traditional vapor barrier on the topsides of CLT panels when applied to KP-12 treated surfaces. KP-14+ offers protection from water absorption, and water staining on engineered wood during construction.
Part of Sansin’s Precision Coat Factory Finish Line of products, KP-14+ is a single-coat vapor permeable membrane coating for wood that meets EN927-5 and EN927-4 moisture absorption testing when applied to KP-12 treated surfaces. This technology is designed to aggressively protect against water absorption and water staining that may occur on the undersides of mass timber panels. By coating the exposed topsides, KP-14+ prevents water leaching through the panel. KP-14+ is unique from other membranes that may entrap water, leading to mold growth, wood rot and decay.
KP-14+ is a highly durable, water-borne product that is low in VOC’s, making it a sustainable choice for the industry. KP-14+ can be field, or factory applied to protect the wood from weathering or water absorption during construction. Proper preparation and application methods should be followed according to our product data sheet.
