Smart Prime Advanced Water-Base Technology Primer For All Projects

Zinsser Smart Prime

Generic Type: White pigmented, modified acrylic water-base primer-sealer stain killer & bond coat.

• Bonds to glossy surfaces without scuff sanding
• Formulated with proprietary stain-blocking resins
• Rust inhibitive – may be used to prime ferrous metal
• Dried film is mold and mildew resistant
• Binds moderately chalky surfaces
• Dries in minutes, can be recoated in 1 hour

Apply to interior and exterior walls, ceilings, doors, trim, fascia, soffits, foundations, railings, and related paintable surfaces. Smart Prime bonds to wood, plaster, concrete, gloss enamels, hardboard, glass and tile. Provides a rust inhibitive coating on iron railings, steel frames, piping, etc. Resists the growth of mold and mildew on primer film in damp, humid environments. Seals porous surfaces and traps most stains in the primer film – water, graffiti, grease, rust, cedar & redwood tannin, creosote, and asphalt stains. Allow two hours dry time when using as a stain blocker. Some stains may require a second coat.

Dry Time: In most cases Smart Prime will dry to the touch in 30 minutes and can be recoated after 1 hour. The dry primer film develops full adhesion after it cures in 7 days. Lower temperatures, higher humidity and the addition of tint will prolong dry and cure time.

Coverage: Approx. 400 sq. ft. (37 m2) per gallon on smooth, painted, non-porous surfaces; 350 sq. ft. (33 m2) per gallon on rough, unpainted, porous surfaces. Application losses may vary according to the porosity of the substrate and the method of application and should be taken into account when estimating the quantity of product needed.
