TEC Multipurpose Primer is an acrylic latex based primer for use with TEC brand self-leveling underlayments. It may also be used to enable the bonding of other TEC brand surface preparation products and polymer-modified mortars to difficult substrates such as metal, glazed ceramic tile, gypsum-based underlayments and concrete treated with certain types of curing compounds (silicate or acrylic resin curing compounds only) and well bonded epoxy coatings. Use to prime resin and metal backings on natural stone and install with polymer-modified mortar instead of epoxy mortar. For peel and stick tile installation, primer can be used on dry, porous concrete, gypsum cement underlayments and plywood. May also be used to promote bond over cold-rolled steel substrates.
 
Key Features and Benefits
• Multipurpose primer for all approved porous and non-porous substrates
• Easy to apply with brush or roller for non-porous surfaces, or push broom for porous surfaces
• Enables installation of ceramic tile or natural stone directly to metal, gypsumbased underlayments, glazed tile (without scarifying) and well bonded epoxy coatings
• Contributes to LEED® project points
• Solvent-free
• Low VOC
