Skip. Current water shield formula stays proprietary and undisclosed.
Scotchgard Outdoor Water Shield is a spray-on water repellent without public PFAS disclosure or third-party verification. Earlier Scotchgard products contained PFAS; today's formulation is unknown.

What (2 pack) Scotchgard Outdoor Water Shield is made of, ingredients and materials
Scotchgard Outdoor Water Shield is a spray-applied water-repellent coating with a proprietary formula that 3M does not publicly disclose. The product is designed to bead water on outdoor textiles, cushions, and upholstery, which typically requires either fluorinated compounds (including potential PFAS) or silicone-based polymers. Without ingredient transparency, the actual chemistry driving water repellency cannot be independently assessed. Aerosol delivery adds concern about inhalation exposure to propellants and fine particulates during application.
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) and aerosol inhalation
Scotchgard water shield is delivered as a pressurized aerosol spray, which generates fine particulate and propellant inhalation exposure during application. The undisclosed propellant type and solvent system cannot be assessed for respiratory or neurological effects.
Skin and eye irritation from direct contact
Spray coatings applied to fabrics can drift and contact skin or eyes during application. Without full ingredient disclosure, specific irritancy potential cannot be confirmed, though water-repellent formulas commonly contain surfactants or solvents that may irritate mucous membranes.
Dermal absorption from treated textiles
Once applied to cushions, outdoor furniture, or apparel, the coating remains in contact with skin. If the formula contains reactive or migratory compounds, prolonged contact could facilitate absorption; this risk cannot be ruled out without chemical disclosure.
PFAS
3M's legacy Scotchgard textile products contained PFOA and other PFAS; the water-shield formulation status remains undisclosed. Given no public statement of reformulation and proprietary positioning, PFAS content cannot be ruled out.
Source, ATSDR ↗What’s reassuring
Off-gassing or degradation byproducts
No established reports of Scotchgard water shield off-gassing or degradation products exist in public literature. However, lack of disclosure prevents assessment of whether UV exposure, heat, or weathering could generate secondary compounds of concern.
The full breakdown
The brand's record and disclosure
3M has faced significant legal and regulatory scrutiny over PFAS contamination and has been largely silent on whether Scotchgard water-shield formulations contain fluorinated compounds or PFAS alternatives. The company has not voluntarily certified this product as PFAS-free or disclosed its chemical contents on safety data sheets accessible to consumers. 3M's historical use of PFAS in legacy Scotchgard products for textiles (since the 1950s) creates justified skepticism about reformulation claims unless explicitly verified. The proprietary label effectively prevents independent safety verification.
How it compares in its category
Outdoor fabric protectants span a spectrum from older fluorochemical formulas (still widely sold) to newer silicone-based or wax-based alternatives marketed as PFAS-free. Products with fully disclosed ingredients and third-party certifications (e.g., Bluesign, OEKO-TEX) offer greater transparency than Scotchgard. Many competitor brands have moved toward transparent silicone or plant-based repellents in response to PFAS concerns; Scotchgard's silence suggests no equivalent reformulation effort. The 10.5 oz aerosol format is standard but increases inhalation exposure risk compared to liquid pump or brush-applied alternatives.
If you buy it
Apply only in well-ventilated outdoor spaces or with respiratory protection to minimize inhalation of aerosol particles and propellants. Avoid application to textiles you will sleep on or that will contact skin frequently until fully cured and aired (typically 24-48 hours). Reapplication is typically needed every 6-12 months depending on weather exposure and washing frequency. Do not use on fabrics intended for children's items or high-contact surfaces without understanding the full chemical composition first.
