Treating

Protecting OSB from fungal or insect attack

  • We recommend a 3-minute dip cycle with a solvent-based system
  • An adequate amount of preservative will be absorbed in this way
  • Avoid double-vacuum systems and water-based chemicals, as these can cause damage

OSB and fire retardants

  • Some fire retardant impregnation systems use double-vacuum and water-based systems
  • For safety, always get the structural performance characteristics from the treatment company and follow their recommendations
  • Alternatively, use fire retardant paints and finishes as these can be used on OSB
