Application Directions

  • Before You Begin instructions
    • Surface should be clean, porous and free of any previous finishes
    • For concrete: sprinkle a few drops of water on the surface; if they are quickly absorbed then the surface is ready to prep
    • Let wood dry in the open air for 3-5 days
    • Always apply to a small test area and allow to dry
    • Cover nearby bushes and flowers
    • Apply when air and surface temperatures are between 50 ˚F and 90 ˚F
  • Preparation Warning
    WARNING! Removal of old paint by sanding, scraping or other means may generate dust or fumes that contain lead. Exposure to lead dust or fumes may cause brain damage or other adverse health effects, especially in children or pregnant women. Controlling exposure to lead or other hazardous substances requires the use of proper protective equipment such as a properly fitted respirator (NIOSH approved) and proper containment and cleanup. For more information, call the National Lead Information Center at 1-800-424-LEAD (in US) or contact your local health authority.
