EXTERIOR / INTERIOR PRIMER
Thermo-Shield® Exterior / Interior Primer is a water-based elastomeric coating and sealant made from 100% acrylic resins. This extremely durable, penetrating sealant is specifically designed with tenacious adhesion to be used as a prep and prime coat and/or to restore coarse or highly weathered surfaces. This product is made with mildew resistant agents and is highly resistant to the sun’s ultraviolet rays. Thermo-Shield® Exterior / Interior Primer is a permanently flexible, breathing membrane, allowing moisture from the substrate or building interior to escape while remaining impervious to water penetration from the exterior.
Thermo-Shield® Exterior / Interior Primer is engineered and developed to perform well under severe industrial, commercial, institutional, residential and agricultural applications. This product is ideal for use over gypsum board, in addition, when local codes require the use of a primer on exterior and/or interior concrete block, pre-cast concrete, masonry, wood shake, brick, stone, slate, stucco and wood.
All surfaces must be clean, dry and free of dust, dirt, oil, grease and mildew. Remove any trace of mildew by washing with a solution that kills mildew spores. Old paint/coating or residue that is loose or peeling must be removed by scraping, sanding, wire brushing or pressure washing. Avoid using cleaners with built-in wax or silicone additives since this may affect coating bond.
This product is designed as a low-hide base or primer coat only. It is not intended to be used as a top or finish coat. Maximum adhesion is achieved only when the surface is clean, dry and properly prepared. Apply one coat at approximately 0.14 – 0.2 L / m² (200 – 300 square feet / gallon); material requirements will increase with coarse or highly weathered surfaces. A continuous film should be applied, making sure all surfaces are uniformly coated and free from voids, pinholes and blisters. Apply with a brush, roller (1 14” Nap) or spray equipment (see details below).
