Z-Prime Plus Zehrung Brands Universal exterior/interior oil-based stain-blocking primer

Z-Prime Plus is a premium quality oil-based, quick-drying, white pigmented primer-sealer for all architectural top coats on any paintable surface.

Z-Prime Plus kills tannin stains on cedar and redwood.  Specially formulated with active ingredients that chemically neutralize tannic acid, Z-Prime Plus effectively seals out the bleeding stains that can discolor new or previously-painted cedar and redwood.

Z-Prime Plus has been fortified to withstand the harsh conditions unique to the Pacific Northwest.  Unlike conventional alkyd primers, Z-Prime Plus is ideal for use outdoors where both exterior durability and quick re-coat time are important.

Dries super-fast, usually ready for top coating in one hour.

Sticks to problem surfaces, indoors or out.  Ideal for chalky exterior siding and trim, gloss enamels, old varnish, aluminum, clean galvanized metal, and oil or grease spots.  Excellent for bare or previously-painted plywood and lumber, siding, plaster, hardboard, drywall, cured concrete, and wrought iron.  Stainblockz^TM formula helps control rust.

Undercoats latex or oil-based enamels, beautifully.  Use indoors or out to improve enamel holdout and prevent variations in top coat sheen.
