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 Volatile organic compounds (VOCs) / respiratory irritants in aerosol formulation, Inhalation exposure to polymer micro-particles and Accumulation of waterproofing coating on fabric over repeated applications on the and not on the Nikwax.
  • The Nikwax is wax-based waterproofing where the is unknown waterproofing polymer spray coating, 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.

Both products run through the same public rubric, which covers materials, coatings, brand disclosure, lab findings, and recalls, plus a beyond-PFAS hazard analysis. Grades are model-based estimates, not lab tests. How grades work →
