  • Usage
    This paint is ideal for use on properly prepared exterior surfaces including bare wood, previously painted wood siding and trim, brick, concrete, cement, stucco, non-rusted galvanized gutters and downspouts. DO NOT USE over hardboard siding or gummy pine; use an exterior oil primer for these surfaces.
  • Prep
    Surface should be clean, dry and dull. Glossy surfaces should be dulled. Thoroughly clean the surface and remove all dirt, dust, chalk, rust, grease, wax, mildew and peeling paint and allow to dry. See technical data page for additional surface prep.
  • Application
    Stir thoroughly before and during use. Apply with a premium quality polyester brush, “one coat” roller or airless sprayer. If applying by sprayer, back-roll or back-brush to work primer into the surface. Apply a liberal coat of primer uniformly, working well into the surface. Allow to dry at least 2 hours before applying a latex topcoat, overnight for oil topcoats.
