20 Mil Maroon/Black Tarp 12 x 16 - Extreme Heavy Duty Waterproof Cover

In this review of the 20 Mil Maroon/Black tarp 12 x 16, the bottom line is straightforward: this is for anyone who needs a noticeably thicker, weatherproof tarp with finished sizing and reinforced edges for heavy outdoor use. The reviewer found the tarp best where durability and secure tie-down points matter most, such as temporary roof patches, covering boats or patio furniture, and long-term outdoor storage. The review highlights that the tarp is made from 100% virgin polyethylene, carries metal grommets every 24 in and keeps full claimed dimensions rather than coming up short.

Key Features

• Finished size: The tarp delivers the full 12 x 16 finished dimensions so you get the actual coverage advertised without losing inches at the edges.
• 100% virgin polyethylene: Built from pure, non-recycled material for greater tear resistance and reduced risk of rot compared with mixed-material tarps.
• Reinforced edges and grommets: Metal grommets every 24 in and reinforced hems make it easy to tie down the tarp securely and withstand tension.
• 20 mil thickness: The extra thickness gives weight and substance that helps it act more like a truck tarp for demanding covers.
• Weather protection: Waterproof and UV resistant construction helps protect items from sun, rain, wind and snow over extended outdoor use.

Who It's For

This tarp is well suited to homeowners, contractors and outdoor enthusiasts who need a robust, reliable cover for roofs, boats, pools, patio furniture or camping uses. The finished sizing and heavier 20 mil material make it a good choice for seasonal protection and short-term repairs where a thin tarp would fail.

Those who only need a lightweight temporary cover for occasional indoor use or want a near-invisible, ultra-light tarp for backpacking should look elsewhere; the weight and thickness here are intentional and add durability at the cost of portability.

Pros & Cons

Pros

• Thick 20 mil construction feels substantial and performs well in sun and rain.
• Finished size delivers expected 12 x 16 coverage without unexpected cut margins.
• Strong grommets and reinforced edges make secure tie-downs easy and more durable.

Cons

• Heavier weight reduces portability for hiking or minimal gear applications; not ideal for lightweight camping.
• A few customers reported tearing under extreme stress, so exceptionally rough use may still damage it.

Our Verdict

The 20 Mil Maroon/Black 12 x 16 tarp is a practical buy for anyone needing a thicker, weatherproof cover with reliable finished sizing and reinforced tie points. It offers strong value for roof patches, boat covers and long-term outdoor protection, but its weight makes it less suited to ultralight applications.
