Universal Primer Pro is a premium one component, interior, acrylic primer designed for use with Bostik’s line of underlayments and patches. Universal Primer Pro’s deep penetrating formulation can be used on a wide variety of substrates including concrete, wood, tile, well bonded VCT, epoxy, gypsum underlayment, cutback and other adhesive residues not affected by water. Universal Primer Pro is rapid drying and will adhere to both porous and non-porous substrates.
GENERAL NOTE: Universal Primer Pro is not a vapor barrier. Test substrate as per ASTM F-1869 for (MVER) and/or ASTM F-2170 for (RH%). If levels exceed those permissible by any component in the flooring system, apply a Bostik moisture vapor barrier coating (i.e. Bostik Slab-Cote, D-250 or D-261). All surfaces must be clean, sound, dry, 50F(10C) and free of oil, wax, grease, sealers and/or curing compounds, urethane, paint, asphalt, loose surface material or any contaminate that will act as a bond breaker. Never use acid or mastic removers on any surface to which a Bostik product will be applied. If sealers and/or curing compounds are present they must be removed by mechanical means prior to application. Refer to the data sheet of the Bostik cement based product being installed. Follow the specific substrate preparation, priming, mixing and application guidelines. Adhere to all product limitations and if unsure about a particular application, contact Bostik Technical Service.
