Where these two actually differ
- We flag Formaldehyde resins (in crosslinking layer), Volatile organic compounds (VOCs) in solvent carrier, Aerosolization and respiratory exposure during spraying and Fluorocarbon repellent (PFAS or PFAS-analogues) on the Angelus 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 Angelus.
- The Angelus is spray coating, polymer-based water/stain repellent where the Nikwax is wax-based waterproofing, 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 Angelus grade, at 35% confidence against 78%, because it discloses less.
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 →
