Pecora XL-PermULTRA VP Coating is a high-performance solution designed to control air and moisture vapor movement through the building envelope. As a system component, it offers complete air and vapor barrier protection for your building.
Pecora XL-PermULTRA VP Coating is a versatile product that can be applied over various common building materials such as concrete block, concrete, exterior gypsum sheeting, plywood, OSB, and more. It is a primerless, single-component, high-performance elastomeric fluid applied STPU (Silyl Terminated Polyurethane) coating. Combining the best properties of silicone and urethane, it functions as an air and water barrier for exterior wall assemblies.
This durable elastomeric weatherproofing membrane is applied in a single coat using an airless sprayer or roller, offering two to three times the coverage of other fluid applied products. Its excellent elasticity and crack-bridging capabilities contribute to a seamless and airtight building envelope.
Product Advantages:
– STPU chemistry ensures enhanced compatibility with a diverse selection of wall components.
– Eliminates construction delays as it can be applied during inclement weather conditions.
– Saves on labor costs with its primerless application and single-coat coverage.
– Exhibits excellent weatherability, being UV and water resistant.
– Provides versatility with the option of spray or roll application.
– Permeable, allowing for water vapor diffusion.
– Resistant to water and air penetration in both normal and extreme weather conditions.
– Low VOC, compliant in all areas of the U.S.
Pecora XL-PermULTRA VP is primerless, low-VOC, and can be used on damp substrates and green concrete, helping reduce delays on the jobsite. It can also be used in inclement weather conditions, adding flexibility for real-world scheduling. With strong adhesion, excellent weatherability, and compatibility with a wide range of wall components, it is a reliable choice for commercial wall assemblies where air control, water resistance, and vapor permeability all matter.
