Jason Markk Repel Spray
Skip until brand discloses or tests for PFAS in this waterproofing spray.
This water-repellent protective treatment for shoes and textiles has no PFAS disclosure or third-party testing. Given the spray's waterproofing function, PFAS content is a material concern.

What Jason Markk Repel Spray is made of, ingredients and materials
Jason Markk Repel is a proprietary spray-on water-repellent coating for footwear, designed to bead water off shoe surfaces. The exact chemical formulation is not publicly disclosed by the brand. Given that durable water-repellency in consumer sprays typically relies on fluorinated compounds (PFAS family members like Teflon-type coating or polyfluoroalkyl substances), this product's silence on composition is the primary concern. The spray is applied as an aerosol, meaning inhalation exposure during application is a realistic exposure pathway.
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.
Volatile Organic Compounds (VOCs) from solvent carriers
Aerosol spray formulations require volatile solvents for dispersal and quick drying. Inhalation of spray mist can cause headache, dizziness, and respiratory irritation during application; ventilation is essential to minimize exposure.
PFAS
If the proprietary formulation contains Teflon-type coating or other fluorinated polymers for water-repellency (likely but unconfirmed), inhaling dried particles or aerosol residue may expose lungs to materials with unknown long-term safety profiles in humans. This hazard is conditional on the undisclosed formula.
Source, ATSDR ↗Aerosol propellant effects on respiratory system
Some aerosol propellants can irritate airways or trigger bronchospasm in sensitive individuals, particularly those with asthma. The brand does not specify propellant type.
Skin and eye contact irritation
Spray mist can contact skin and eyes during application. Solvent-based formulations typically cause mild to moderate irritation; no specific incident reports exist for this product, but contact with eyes or mucous membranes should be avoided and rinsed immediately.
What’s reassuring
Microplastic shedding from dried coating layer
Water-repellent spray coatings can degrade and shed microparticles into the environment with repeated foot flexion and rain exposure. No published data exists on microplastic release from Jason Markk Repel specifically, but this is a known issue in the category.
How is this PFAS grade calculated?
The brand's record and disclosure
Jason Markk has not published safety data sheets, ingredient lists, or third-party PFAS testing results for this product in publicly available sources. The brand markets itself as a sneaker care specialist but has not made public commitments to PFAS-free formulations or transparency standards common in eco-focused footwear brands. No major recalls or safety incidents have been documented for this specific spray. The lack of disclosure is the defining gap rather than a documented violation.
How it compares in its category
Waterproofing sprays for shoes exist across a wide spectrum, some brands (e.g., Crep Protect, Scotchgard) also lack full PFAS disclosure but have longer market histories; others emphasize wax-based or silicone-based alternatives that avoid fluorinated chemistry. Jason Markk Repel sits in the middle of the market by reputation and pricing but offers no competitive advantage in safety transparency. If water-repellency is your priority and PFAS concern is secondary, competing products with similar or worse disclosure exist; if transparency is the driver, several smaller brands offer plant-based or PFOA-free claims.
If you buy it
Apply in a well-ventilated space or outdoors to minimize aerosol inhalation. Follow the brand's dry-time guidance (typically 24 hours before shoe use) to allow solvents to evaporate. Reapply every 3 to 6 months depending on wear and weather exposure; more frequent application increases cumulative inhalation risk. Store away from heat and ignition sources. If you are pregnant, have respiratory sensitivities, or live with young children, request a safety data sheet from the brand before purchase; their silence suggests one does not exist publicly.
