12x20 FT Green Ultra-Heavy Duty Tear-Resistant Canvas Tarp

In this review of the 12x20 FT green ultra-heavy duty canvas tarp, the bottom line is straightforward: this tarp is built for long-term outdoor protection where strength and waterproofing matter most. The tarp's 28 mil organic silicone coating and high-strength polyester filament give it a noticeably heavy, durable feel that stands up to sun, rain, wind and abrasion. For anyone needing a reliable cover for a boat, vehicle, pool or temporary tent, this tarp delivers protection and longevity without extra fuss.

Key Features

• 28 mil organic silicone coating: Provides robust waterproofing and improves resistance to UV and aging so covered items stay dry and protected.
• High-strength polyester filament: Core fabric offers excellent tear and abrasion resistance for long service life under rough conditions.
• Reinforced edges with internal rope: Heat-bonded 2 in fabric edges and internal ropes reduce tearing at stress points and make securing the tarp easier.
• Plastic-reinforced corners: Extra corner protection prevents early abrasion where the tarp is most likely to wear.
• Aluminum grommets every 20 in: Corrosion-resistant grommets spaced for secure lashing and straightforward attachment to structures or equipment.
• Versatile applications: Suitable for covering vehicles, pools, boats, hay or temporary construction uses thanks to its combination of strength and waterproofing.

Who It's For

The tarp is best for homeowners, small-farm users and outdoor contractors who need a heavy-duty, waterproof cover for medium to large items such as boats, trailers, pools, stacked materials or temporary tent structures. Its weight and reinforced build are ideal where long-term exposure to sun and weather is expected.

Those who need an ultra-light or ultra-compact tarpaulin for frequent backpacking or minimalist camping should look elsewhere, as this product prioritizes durability and protection over packability or minimal weight.

Pros & Cons

Pros

• Very durable construction with tear resistance from the polyester filament and silicone coating.
• Effective waterproofing and UV resistance for extended outdoor use.
• Reinforced edges, plastic corners and widely spaced grommets make fastening reliable and reduce wear.
• Suitable for many applications from vehicle and pool covers to construction uses.

Cons

• Heavier and less packable than lighter tarps, so not ideal for ultra-mobile uses.
• Some customers give mixed feedback about grommet performance, so extreme heavy-duty tie-downs may need extra reinforcement.
