20 x 16 ft 20 Mil Heavy Duty Tarp Cover Brown/Black - Waterproof UV

In this review of the 20 x 16 ft 20 mil tarp cover, the bottom line is simple: this tarp is aimed at homeowners and outdoor workers who need a heavy, weatherproof sheet that stays the advertised finished size. The reviewer found it most valuable for covering roofs, boats, patio furniture and gear where reinforced edges and frequent grommets matter. The single biggest reason to consider this tarp is its combination of thick virgin polyethylene construction and reinforced grommets that make it reliable for long-term outdoor protection.

Key Features

• Finished size: The tarp is sold as the full finished size so buyers get the full 20 x 16 ft coverage without losing inches at the edges.
• 100% virgin polyethylene: Built from non-recycled material for a sturdier fabric that resists tearing, rot and premature breakdown compared with mixed-material tarps.
• 20 mil thickness: The extra-thick sheet gives substantial weight and body, which helps it stay put and perform for roofing, camping and heavy cover tasks.
• Reinforced edges and grommets: Edges are strengthened and metal grommets every 18 in allow secure tie-downs with rope or bungee cords without easily pulling out.
• Waterproof and UV resistant: The tarp sheds rain and blocks sun exposure so it can be used year-round in wet or sunny conditions without immediate UV breakdown.

Who It's For

This tarp is well suited for homeowners, contractors and outdoorspeople who need a dependable, multipurpose cover for roofs, boats, pools and patio furniture; its heavy weight and reinforced corners make it practical when you need longer-term protection rather than a temporary sheet. Campers who build canopies or use a tarp as a groundsheet will also appreciate the thicker material and finished sizing.

Those who should look elsewhere include buyers seeking a very light, packable tarp for backpacking or ultralight use, or anyone requiring precise custom-cut sizes beyond standard finished dimensions. Also, if absolute professional-grade truck tarp strength is required, compare industrial tarpaulins designed specifically for continual heavy abrasion.

Pros & Cons
