Where these two actually differ
- We flag Inhalation of spray aerosol, Skin contact irritation and Polymer or wax coating degradation over time on the Nikwax and not on the Nikwax.
- We flag Respiratory irritation or fume inhalation during application and PFAS in water repellency treatment on the Nikwax and not on the Nikwax.
- The Nikwax is Wax-based DWR (durable water repellent) treatment where the Nikwax is wax-based waterproofing, which is most of the difference in these two grades.
- These two are level, close enough that price and fit should decide it rather than our grade.
Both products run through the same public rubric: 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 →
