Where these two actually differ

  • We flag Undisclosed fluorinated repellent chemicals (possible PFAS), Solvent and propellant inhalation hazard, Skin and eye irritation from undisclosed surfactants or emulsifiers and Unknown degradation byproducts under heat or UV exposure on the and not on the Nikwax.

  • The is Proprietary stain guard spray coating 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 grade, at 35% confidence against 78%, because it discloses less.
