White 20 x 20 20 Mil Heavy Duty Tarp Cover - Waterproof, UV

In this review a 20 x 20 white, 20 mil tarp from Core Tarps is evaluated for outdoor protection and general utility. The bottom line: this tarp is best for homeowners, contractors, and campers who want a full-size, thick poly tarpaulin that resists sun and water while offering reinforced edges for secure tie-downs. The reviewer found the finished sizing and 100% virgin polyethylene material to be the single biggest reasons to choose this cover over thinner, recycled alternatives.

Key Features

• Finished size: The tarp is sold at its full stated dimensions so buyers receive a true 20 x 20 tarp without losing inches to hemming or trimming.
• 100% virgin polyethylene: Using non-recycled material improves durability and reduces the chance of early rot or breakdown compared with mixed-material tarps.
• Reinforced edges: Heavy hems and a 16 x 16 weave count add tear resistance and help the tarp hold shape under tension.
• Metal grommets every 18 in: Grommets spaced at 18 in allow secure attachment with bungee cords or rope for roofs, boats, and patio covers.
• Weatherproof construction: The ultra-thick, waterproof and UV resistant sheet stands up to sun, rain and snow for seasonal outdoor use.

Who It's For

This tarp suits homeowners covering equipment, furniture, pools or small roofs, and outdoors people who need a durable cover for camping shelters and gear. Contractors or DIYers who want a dependable, full-size protective sheet that won't come up short on any side will appreciate the finished sizing and thicker virgin material.

It may not be the best choice for lightweight, packable needs where minimal weight matters, or for applications demanding industrial-grade truck tarp strength; several users praised durability while a few noted tears under very high stress, so extreme industrial use should be evaluated carefully.

Pros & Cons

Pros

• Strong, thick material from 100% virgin polyethylene gives reliable water and UV protection.
• Finished size means you get the true 20 x 20 area without unexpected shortfalls.
• Reinforced edges and metal grommets every 18 in make tie-downs easy and secure.
• Multipurpose design covers roofs, boats, patios and works well for camping shelters.

Cons

• Weight and thickness make it less convenient to pack for backpacking or very portable use.
