Quick tips for using FSC-88 WB HDU Primer

  • Use FSC-360 WB HDU Filler to fill cuts, dings any other damage prior to priming with FSC-88 WB HDU Primer.
  • Brush or Roller- apply a smooth creamy coat and thoroughly work into surface. Allow surface to become tack free before applying a 2nd creamy coat. Do not sand between coats. Reduce with water about 3% when applying with a roller to reduce drag and extend drying time.
  • Spray- apply initial coat to all surfaces requiring a smooth finish. Do not allow to run. When tack free (about 10 minutes) apply a 2nd, slightly heavier coat. If desired smoothness has not been achieved, continue applying multiple thin coats until desired smoothness is reached. Never sand between coats.
  • Sanding of FSC-88 WB HDU Primer can take place as soon as it does not ball up on the sand paper.
  • Painting- once completely dry, FSC-88 WB is compatible with most interior and exterior paints and lacquers. Be sure paint all surfaces for proper paint tension balance.
  • Ask for free copy of priming video.
  • Use shop fan blowing across primed item to assure complete drying of FSC-88.
