12x20 ft 12 mil Heavy Duty Poly Tarp - Waterproof, UV Resistant

In this review of the 12x20 ft 12 mil poly tarp, the bottom line is simple: this tarp is for anyone who needs a heavy, reliable cover for outdoor gear and vehicles. The reviewer found the tarp's single biggest advantage to be its construction from pure virgin polyethylene, which makes it noticeably tough and rot-resistant compared with thinner, recycled tarps. For yards, truck beds, boats or camping shelters that need waterproof protection and long-lasting material, this tarp delivers a no-frills, durable solution.

Key Features

• Pure virgin polyethylene: Using non-recycled material gives the tarp stronger fibers and better resistance to rot and degradation over time.
• 12 mil thickness: The heavy 12 mil gauge makes the sheet difficult to tear and suitable for demanding covers and jobsite uses.
• Finished full size: The listed 12x20 ft dimension is the finished size, so buyers can expect coverage close to the stated measurement.
• Double-side laminate waterproofing: Laminated on both sides to reduce water penetration and help keep items dry in rain and damp conditions.
• Versatile protection: Works as a yard equipment cover, truck bed or boat cover, and as a shelter or debris sheet for camping and outdoor projects.

Who It's For

This tarp suits homeowners, contractors, and outdoor enthusiasts who need a heavy-duty, waterproof cover for equipment, cars, boats or temporary shelters. If you frequently store gear outside or haul debris, the 12 mil construction and laminated surfaces make it a practical choice for routine exposure to weather.

Those looking for ultra-lightweight tarps for backpacking or exact-fit custom covers should look elsewhere; this product is purposefully heavy and intended for protection and durability rather than weight savings or precision fit.

Pros & Cons

Pros
