Scotchgard Sun and Water Shield
Scotchgard's composition undisclosed; avoid if PFAS-concerned.
Host's Scotchgard Sun and Water Shield is a water and stain resistant treatment for furniture, but the brand does not disclose PFAS content or ingredient specifics. Without independent testing or certification, PFAS risk remains unconfirmed.

Why this grade
Waterproof / stain-resistant treatment
water-repellent coating treatments have historically used PFAS.
Category baseline
furniture is a category where PFAS exposure is more common.
Vague safety claims only
Uses vague language ("eco-friendly", "clean") without a specific PFAS statement.
The full breakdown
What it's made of and why it matters
Scotchgard Sun and Water Shield is a proprietary fluorochemical coating applied post-manufacture to fabric. Host does not publicly disclose its exact formulation, but water and stain repellents of this type have historically relied on fluorinated compounds to achieve their hydrophobic and oleophobic properties. The coating sits on the fiber surface rather than being woven in, meaning durability depends on reapplication over time.
The brand's record and disclosure
Host has maintained silence on PFAS content in Scotchgard products despite industry-wide scrutiny since 2015. The company has not pursued third-party certifications (e.g., OEKO-TEX, bluesign) that would restrict PFAS "forever chemicals", nor has it published a timeline for PFAS phase-out. This lack of transparency is notable given competitor moves toward fluorine-free alternatives.
How it compares in its category
Scotchgard remains one of the most widely used furniture treatments in North America, but its market dominance does not reflect safety leadership. Alternatives exist: fluorine-free water repellents (e.g., paraffin-based, silicone-based) are available from brands like Crypton and some eco-label certifiers, though they typically offer shorter durability. This product is a legacy formulation in a category shifting toward disclosure-first competitors.
If you buy it
Apply only in well-ventilated spaces and allow 24-48 hours for full cure before contact with skin or food. Avoid reapplication more than once every 2-3 years unless staining is severe; over-treating increases cumulative chemical load. Vacuum treated furniture regularly and do not wash fabric aggressively, as this degrades the coating and may release particles. If PFAS exposure is a household concern, prioritize fluorine-free alternatives for new purchases.
Beyond PFAS: other things we checked
Established hazard classes for this product type, assessed from public information. These never change the PFAS grade; a Likely flag caps the Verdict at “Buy with care.”
Volatile organic compounds (VOCs) during application
Fluorochemical coatings typically release VOCs during curing; Host does not publish emission data. Inhalation risk is greatest during the application window (first 48 hours).
Microparticle shedding from coating degradation
As the topical coating wears, fine particles may be released into air and potentially ingested via hand-to-mouth contact. No manufacturer data on particle size or composition is publicly available.
Allergic or irritant contact sensitization
No established recalls or widespread reports of dermatitis from Scotchgard Sun and Water Shield exposure, but individual sensitivity to fluorochemicals or surfactants cannot be ruled out.
Contamination of indoor dust and household surfaces
Studies have detected PFAS in household dust; treated furniture is a known source. While this product's specific contribution is not quantified, the undisclosed formulation prevents consumer assessment of relative risk.
Flame retardant additives
Host does not indicate whether Scotchgard formulations contain added flame retardants. Many furniture treatments historically bundled flame resistance; absence of disclosure makes this uncertain.
What we don’t know
This grade is a model-based estimate from public materials, coatings, and brand disclosure at 45% confidence. It is not a lab result.
No independent PFAS lab test is on record for this exact product. A lab test could move the score in either direction.
The brand has not made a specific, verifiable PFAS-free statement, so part of this score reflects that missing disclosure rather than a confirmed material.
Formulations and coatings change between production runs. Always check the current label before buying.
