Guardsman Wood Protector Weather Defence Aerosol
Skip until PFAS content is disclosed or tested independently.
Guardsman wood protector uses undisclosed water-repellent coating formulation typical of products that historically relied on PFAS. No third-party testing or PFAS-free certification exists.

What Guardsman Wood Protector Defence Aerosol is made of, ingredients and materials
Guardsman Wood Protector is a proprietary water-repellent aerosol spray designed for outdoor wood furniture. The formulation likely contains silicone-based or wax-based hydrophobic agents, propellants (typically hydrofluorocarbon or hydrocarbon blends), and solvent carriers. The brand does not publicly disclose whether PFAS compounds are used as water-repellent agents, which is common in this product class and a major safety concern. Aerosol delivery means inhalation exposure to propellants and solvents during application is inevitable.
What’s concerning
Category baseline
The starting point for this type of product, before anything specific to this product is counted.
Vague safety claims only
Uses vague language ("eco-friendly", "clean") without a specific PFAS statement.
Waterproof / stain-resistant treatment
Water-repellent coating treatments have historically used PFAS.
Volatile Organic Compounds (VOCs) from solvents and propellants
Aerosol wood coatings typically contain hydrocarbon or fluorocarbon propellants and organic solvents. Inhalation during application can cause dizziness, headache, and respiratory irritation; outdoor use and respiratory protection are essential.
PFAS
Water-repellent coatings for wood historically relied on PFAS-based surfactants; Guardsman's refusal to disclose formulation makes presence of legacy PFAS compounds unconfirmed but plausible. PFAS accumulates in soil and groundwater and is separately graded at 35/100 safety.
Source, ATSDR ↗Skin and eye contact irritation from solvent spray
Aerosol delivery creates fine mist; direct contact with skin or eyes during application can cause irritation, burning, and temporary vision impairment. Wear gloves, eye protection, and long sleeves when applying.
PFAS
If PFAS compounds are present, runoff from treated outdoor wood furniture can leach into soil and groundwater, where they persist indefinitely and accumulate in wildlife and food chains. No data on Guardsman's product-specific environmental fate is publicly available.

Formaldehyde / VOCs
Aerosol wood coatings may contain amino-formaldehyde or melamine-formaldehyde resins as binders. No public formulation data or safety sheets for this product confirm such ingredients; contact Granger's for MSDS verification.

The brand's record and disclosure
Granger's (the parent company) manufactures performance textile and outdoor-gear treatments and has not published transparency reports on PFAS use or phase-out commitments. No independent recalls or safety violations specific to this product are on record, but the silence on PFAS composition is a red flag in a market where competitors increasingly disclose or eliminate PFAS-based water repellents. The brand offers no certification from third-party safety or environmental bodies regarding this aerosol formulation.
How it compares in its category
Furniture wood protector aerosols occupy a niche market where liquid brush-applied and pump-spray alternatives exist; aerosol formats are typically chosen for convenience at the cost of higher VOC exposure and propellant waste. Many competitors (e.g., Thompson's WaterSeal, Minwax products) have begun disclosing PFAS-free or PFAS-reduced formulations, making Guardsman's silence stand out. Paste waxes and oil-based coatings applied by brush eliminate aerosol propellant inhalation but require more labor and may offer shorter durability on exterior wood.
If you buy it
Apply only in well-ventilated outdoor spaces (never indoors) and avoid inhaling spray mist; wear a respirator rated for organic vapor if applying to large surface areas. Allow full curing (typically 24-48 hours) before contact, and reapply annually or when water beads no longer form on the wood surface. Check wood furniture for rot, splitting, or mold before each reapplication; coating cannot restore structural damage. Store the can upright in a cool, dry place and dispose of empty containers according to local aerosol recycling or hazardous-waste guidelines.
