CARTMAN 20x20 ft 20 Mil Extra Thick Brown Tarp - Heavy Duty Cover

In this review the CARTMAN 20x20 ft 20 Mil Extra Thick Brown Tarp is judged as a straightforward, no-nonsense protective cover for outdoor use. The bottom line: it is best for homeowners and contractors who need a heavy, waterproof sheet that resists sun damage and stands up to regular outdoor exposure. Our review found the tarp's standout quality is its construction from 100% virgin polyethylene and a dense 16x16 weave, which together deliver a noticeably heavy, sturdy feel compared with lighter, recycled tarps.

Key Features

• Finished Size: The marked 20x20 ft is the exact finished size, so buyers get the dimensions they selected without guessing shrinkage.
• 100% Virgin Polyethylene: Using pure, non-recycled material gives the tarp greater strength and helps prevent tearing and rot under repeated use.
• Superior Durability: At about 260 GSM with a 16x16 weave count, the fabric is noticeably thicker and more puncture resistant than thin poly tarps.
• UV Resistant and Waterproof: Treated material resists sun damage and sheds rain and snow, making it suitable for extended outdoor protection.
• Reinforced Edges: The reinforced hems and grommet points improve reliability when tying down loads or securing the tarp to structures.
• Multipurpose Use: It covers vehicles, firewood, furniture, roofing areas and works well as a groundsheet or temporary shelter for camping.

Who It's For

The CARTMAN 20x20 ft tarp is ideal for homeowners who need a heavy, reliable cover for yard equipment, stacked wood, or seasonal outdoor furniture, and for tradespeople who want a durable, waterproof sheet for jobsite protection. Its heavier weight and reinforced edges suit repeated use and rough handling.

Those seeking an ultra-light, packable tarp for minimalist backpacking or a precisely measured custom-fit cover for a vehicle should look elsewhere, since this product prioritizes thickness and durability over ultralight portability or tailored fit.
