Where these two actually differ

  • We flag Respiratory irritation or fume inhalation during application and PFAS in water repellency treatment on the Nikwax and not on the .
  • We flag Inhalation risk from aerosol propellant, Skin and eye irritation from spray contact, VOC off-gassing during application and drying and Bioaccumulation potential if PFAS-based on the and not on the Nikwax.
  • The Nikwax is wax-based waterproofing where the is fabric protection spray, likely silicone or fluorocarbon resin, which is most of the difference in these two grades.
  • The gap is 25 points, wide enough that this is not a close call, and the Nikwax is the one to buy.
  • We are less certain about the grade, at 35% confidence against 78%, because it discloses less.
