Heavy Duty Poly Tarp 20 ft x 20 ft - Durable 10 Mil Waterproof Cover

In this review of the Heavy Duty Poly Tarp 20 ft x 20 ft the bottom line is straightforward: this tarp is for anyone who needs a large, economical, weatherproof cover that prioritizes basic protection and ease of use. The single biggest reason to buy is the tarp's combination of a 10 mil thickness and a laminated polyethylene face that delivers reliable water and sun resistance for outdoor storage, short-term shelter, and seasonal coverage tasks.

Key Features

• 10 mil thickness: Offers a heavier sheet than thin disposable tarps for improved resistance to tears and punctures during routine outdoor use.
• Waterproof construction: Keeps rain, snow, and moisture off equipment and stored items to reduce exposure-related damage.
• UV blocking surface: The laminated coating helps protect belongings from sun fading and material breakdown when used as a cover or pool shield.
• Reversible silver and black: Two-tone design provides reflective or heat-absorbing sides to suit seasonal or situational needs.
• Grommets every 18 in: Reinforced edges with spaced grommets make tie-down and securing straightforward for a stable fit.
• True finished size: Sized as marked so users can plan coverage for vehicles, equipment, stacks of lumber, or outdoor furniture.

Who It's For

The tarp is best suited for homeowners, landscapers, and jobsite users who need a large, affordable cover for short- to mid-term protection of tools, wood piles, patio furniture, or a small pool. Its weight and grommet spacing make it practical for tying down in windy conditions or draping over irregular loads.

Shoppers who require long-term heavy industrial protection, custom-fit truck covers, or premium abrasion-resistant fabrics should look elsewhere; while the tarp performs well for general protection, some customers report mixed longevity and occasional rips under extreme or prolonged exposure.

Pros & Cons

Pros

• Durable polyethylene and a 10 mil thickness provide solid everyday weather protection.
• Waterproof and UV-blocking surfaces reduce moisture and sun damage.
• Reversible silver/black finish and regular grommets make securing and seasonal use flexible.
• Available in multiple sizes so you can pick a close match to the job.

Cons

• Some users report variable longevity with tearing over time, so it may not match heavy-duty industrial-grade tarps for extended continuous use.
• Thickness perception is mixed among buyers; expectations should match an economical, general-purpose cover.
