Star Brite Waterproofing
Skip until composition is disclosed. Waterproofing treatments often use PFAS.
Star Brite does not disclose the chemical composition of this waterproofing product. Waterproofing treatments commonly contain PFAS; without transparency, risk cannot be assessed.

Why this grade
Waterproof / stain-resistant treatment
water-repellent coating treatments have historically used PFAS.
Category baseline
other 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
Star Brite Waterproofing's exact chemical composition is not publicly disclosed. Waterproofing coatings typically use either fluorinated compounds (PFAS-based) for durable water repellency, silicone, wax, or polyurethane systems. Without ingredient transparency, you cannot determine whether this product uses persistent fluorochemicals that accumulate in the environment and human tissue, or safer alternatives. This opacity is the core safety issue.
The brand's record and disclosure
Star Brite is a marine and automotive care company with a long history, but public disclosure of full ingredient lists and PFAS content is not standard for their waterproofing line. No major recalls or safety controversies are on record for this specific product. However, the brand's silence on formulation despite industry-wide PFAS scrutiny suggests either use of conventional PFAS treatments or unwillingness to clarify safer alternatives, both of which warrant caution.
How it compares in its category
Waterproofing products span a spectrum: budget brands often use older PFAS formulations; premium brands increasingly disclose PFAS-free or reduced-PFAS options (e.g., silicone or polyurethane bases). Star Brite Waterproofing sits in the mid-market marine segment where PFAS-based water repellency was standard for decades. Competing products with explicit PFAS-free claims and published safety data sheets offer better transparency for the same function.
If you buy it
Apply in well-ventilated outdoor settings or poorly ventilated areas away from breathing zones. Do not allow contact with skin or eyes during application. Wash hands and exposed skin thoroughly after use. Store in a cool, dry place away from children and pets. Replace or reapply according to manufacturer instructions, typically annually for high-wear surfaces. Dispose of empty containers per local hazardous waste guidelines.
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.”
PFAS (fluorinated water repellents)
Waterproofing coatings historically rely on PFAS for durable hydrophobic performance. Star Brite has not disclosed composition; industry standard for products of this type and age makes PFAS presence probable.
Volatile organic compounds (VOCs) and solvent exposure
Waterproofing coatings commonly use solvents (aliphatic hydrocarbons, ketones, or esters) to achieve even coverage. No solvent content data is publicly available for this product; inhalation risk depends on formulation and ventilation during application.
Skin and eye irritation from coating solvents
Waterproofing products in this category routinely carry warnings for skin and eye contact. Star Brite's product labeling would specify irritancy; treat as likely based on product class unless label contradicts.
Coating degradation and reapplication frequency
Over time, waterproofing coatings break down and may shed microparticles or release volatile residues. Reapplication cycles create repeated exposure. Product longevity claims should be verified against actual field durability.
Inadequate labeling and formulation transparency
Lack of disclosed full ingredient list prevents independent assessment of specific chemical hazards. This transparency gap is the primary safety concern and distinguishes this product unfavorably from competitors with open formulations.
What we don’t know
This grade is a model-based estimate from public materials, coatings, and brand disclosure at 35% 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.
