Crep Protect Starter Pack
Skip until transparency improves; waterproofing sprays commonly use PFAS, brand silent.
This silicone-based sneaker protection spray repels water and stains without brand PFAS disclosure. Waterproofing treatments for textiles and shoes frequently rely on PFAS chemistry.

What Crep Protect Starter Pack is made of, ingredients and materials
Crep Protect Starter Pack is a silicone-based water and stain repellent spray designed for sneakers and textiles. Silicone polymers themselves are not volatile organic compounds (VOCs) at room temperature, but spray application involves propellants and potential volatile carriers that create inhalation exposure during use. The formula's exact composition beyond silicone is not publicly detailed by the brand, limiting assessment of solvent type, propellant chemistry, and any co-formulants that may pose respiratory or dermal irritation.
What’s concerning
Category baseline
The starting point for this type of product, before anything specific to this product is counted.
No PFAS disclosure
No public statement from the brand about PFAS in this product.
Waterproof / stain-resistant treatment
Water-repellent coating treatments have historically used PFAS.
Inhalation risk from propellant/solvent aerosol
Spray-applied silicone formulas generate fine aerosol particles and volatile carriers during application. Without disclosed propellant type or solvent chemistry, inhalation risk cannot be ruled out, particularly with repeated use in poorly ventilated spaces.
Skin and mucous membrane irritation
Silicone-based sprays can cause mild irritation on contact with skin, eyes, or mouth. Crep Protect's lack of ingredient labeling prevents assessment of co-formulants (surfactants, solvents) that may amplify irritation potential.
VOC off-gassing during drying
Although silicone itself is not typically a VOC, spray formulations often contain volatile organic compounds as carriers or propellants. Shoes treated and worn indoors may off-gas low levels during initial drying and curing, especially in enclosed spaces.
Incomplete disclosure of water-repellent chemistry
The brand does not publicly confirm whether the formulation is entirely PFAS-free or contains fluorinated compounds. Given that many waterproofing sprays include PFAS, this silence is a documented gap in transparency, not a verified absence of PFAS.
Coating degradation and reapplication frequency
Silicone coatings degrade with friction, washing, and UV exposure. Frequent reapplication increases cumulative inhalation and skin exposure over time, compounded by lack of safety data on repeated use.
How is this PFAS grade calculated?
The brand's record and disclosure
Crep Protect has not publicly disclosed ingredient lists, manufacturing certifications, or third-party safety testing for this product. The brand has remained silent on PFAS content despite waterproofing sprays commonly relying on fluorinated compounds (PFAS) for water and oil repellency. No major product recalls or established controversies are on record, but absence of transparency on PFAS and full ingredient labeling is a material red flag for a water-repellent spray product.
How it compares in its category
Shoe waterproofing sprays typically use either silicone, wax, or fluorinated (PFAS-based) repellents. Silicone-only formulas are positioned as lower-PFAS alternatives, but Crep Protect's silence on whether the formulation includes any fluorinated additives undermines this claim. Brands offering comparable silicone sprays (e.g., Jason Markk, Scotchgard fabric protector) often provide broader transparency on chemical composition and environmental stance, making Crep Protect's opacity a competitive weakness.
If you buy it
Apply only outdoors or in well-ventilated spaces to minimize inhalation of spray aerosol and any volatile carriers. Wear nitrile gloves and avoid skin contact; wash hands thoroughly after use. Do not spray near eyes, mouth, or on skin. Allow shoes to dry completely before wearing. Reapply after 3, 6 months or after heavy water exposure, depending on wear; effectiveness declines over time as the silicone coating wears away.
