SYNLawn Artificial Grass
Wait for manufacturer to disclose coating chemistry.
SynLawn artificial grass likely uses polyethylene with water and stain-resistant treatments, but offers no public PFAS disclosure. No third-party testing or certifications confirm safety.

What SYNLawn Artificial Grass is made of, ingredients and materials
SYNLawn artificial grass is polyethylene (PE) fiber backed with a base material, treated with unspecified water and stain-resistant coatings. Polyethylene itself is chemically stable and not inherently toxic; however, the stain-resistant coating chemistry is opaque. These coatings often rely on fluorinated compounds (PFAS family) or siloxanes to repel water and oil. Without disclosure of the specific coating agent, the potential for leaching under heat, moisture, or UV exposure cannot be assessed.
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 coating degradation under UV and heat
Polyethylene-based artificial grass in direct sunlight undergoes oxidative aging. Unspecified water-resistant coatings may degrade and off-gas low molecular weight organic compounds, particularly in hot climates or near reflective surfaces. No published testing for SYNLawn-specific off-gassing rates is available.
Microbial growth and odor in backing if drainage inadequate
Artificial grass backing can harbor bacteria, mold, and fungi if moisture accumulates and air circulation is poor. This is a documented maintenance issue across the category, not specific to SYNLawn, but risk is heightened in wet climates or poorly installed yards.
Polyethylene fiber shedding and microplastic accumulation
Artificial grass fibers can fragment under foot traffic, weather, and maintenance (power-washing). These microplastics may persist in soil and be tracked into the home. This is not unique to SYNLawn but is an intrinsic property of all synthetic turf; long-term soil and indoor dust impact is understudied.
PFAS
The marketing language 'water and stain resistant' in artificial grass products typically signals fluorinated compound use, yet SYNLawn does not specify. This is the primary transparency gap; see separate PFAS grading (30/100) for full assessment.

Heavy metals
Polyethylene colorants and UV stabilizers may include cadmium or lead in older formulations, though modern PE typically uses alternatives with lower heavy metal concern. SYNLawn has not published material safety data or pigment sourcing; no independent testing or recalls naming heavy metals are on record for this brand.

The brand's record and disclosure
Artificial Grass Liquidators has not publicly disclosed coating chemistry, ingredient certifications (e.g., Greenguard, FloorScore), or testing for heavy metals or volatile organic compounds. No major recalls or toxicological studies specific to this brand are on public record. The silence on PFAS use is notable given widespread industry scrutiny of artificial turf and PFAS in similar products; this lack of transparency is a red flag for consumer due diligence rather than evidence of harm.
How it compares in its category
Artificial grass products occupy a gray zone in home safety regulation, they are not FDA-regulated food-contact surfaces, not EPA-registered pesticides, and not subject to flame-retardant mandates. Most competitors (FieldTurf, Astroturf, local installers) similarly withhold coating chemistry. A small subset of premium brands now offer PFAS-free or fluorine-free certifications, making SYNLawn's silence a competitive disadvantage rather than an outlier risk.
If you buy it
Maintain proper drainage and rinse the surface periodically to minimize microbial growth in the backing. Avoid installing in high-heat zones (near reflective windows, dark surfaces that concentrate sun) where PE softening and accelerated coating breakdown may occur. Replace infill sand or rubber crumb per manufacturer guidelines, as these separate materials may carry their own contaminant profiles. Keep pets' contact time reasonable during extreme heat, as PE can release volatile compounds under thermal stress.
