Tarps Heavy Duty Waterproof 20x20 12 mil Thick Tarp - Durable Cover

In this review of the 20x20 heavy duty tarp the bottom line is simple: it is a large, no-frills waterproof cover that works well for users who need a strong, weatherproof sheet for general outdoor protection. Teal Elite's 20 ft x 20 ft tarp stands out mainly because of its claimed 12 mil thickness and reinforced edging, which make it a sensible choice for covering boats, pools, RVs, cars, or for use as a ground or tent footprint. The review finds it to be a good value when durability and size matter more than lightweight packability.

Key Features

• Heavy duty construction: The 12 mil material provides a thicker barrier than many common tarps, giving better resistance to tears and punctures in typical outdoor use.
• Generous size: At 20 ft by 20 ft the tarp covers large objects or creates a sizeable shelter area for camping and yard projects without awkward seams.
• Weatherproof performance: The sheet is designed to be waterproof, UV resistant, and dust resistant so it can be left outdoors several seasons with less fading or moisture penetration.
• Reinforced edges: Reinforced edging and quality stitching reduce fraying and help the tarp keep its shape when tied down under tension.
• Grommet placement: Rust proof grommets every 18 in make it straightforward to secure the tarp to anchor points without guessing spacing.
• Multipurpose use: The tarp is made for both indoor and outdoor tasks, from protecting cargo to creating a campground canopy or pool cover.

Who It's For

This tarp is best for homeowners, campers, and small-boat owners who need a large, economical cover that balances thickness and size. It suits people who plan to leave a cover in place for extended periods and value reinforced edges and grommet spacing for easy tying and anchoring.

Those who need an ultra-lightweight tarp for backpacking, or require military-grade tear resistance and welded corners for heavy commercial use, should consider purpose-built alternatives. Also, buyers who expect guaranteed grommet performance under extreme loads may want to test a sample before committing to long-term heavy use.

Pros & Cons

Pros

• Substantial 20 ft x 20 ft coverage for large objects or campsite layouts.
• Thicker 12 mil material and reinforced edging improve lifespan compared with thin poly sheets.
• Rust proof grommets every 18 in make installation quick and predictable.
• Waterproof and UV resistant finish helps protect items from sun and rain.

Cons

• Some users report mixed durability around grommet areas when used under very high stress, so heavy-duty lashings may cause pull-through over time.
• At 12 mil it is not the lightest option for pack-in trips and can be bulky to store for campers who carry everything by hand.
