20 x 30 Green/Black 5 Mil Tarp Cover - Waterproof, UV Resistant

In this review the Core Tarps Classic 5 Mil Tarp Cover (20 x 30, green/black) is evaluated for people who need an affordable, heavy-duty cover that holds up outdoors. The bottom line: it is best for homeowners, campers, and DIYers who want a full finished-size tarp made from 100% virgin polyethylene with reinforced edges and widely spaced metal grommets for easy tie-downs. The single biggest reason to buy is the finished sizing and durable construction that delivers reliable weather protection without surprising shortfalls in dimensions.

Key Features

• Finished Size: The tarp delivers the full 20 x 30 finished measurement so you get the full coverage advertised rather than a slightly smaller sheet.
• Virgin Polyethylene: Made from 100% virgin polyethylene which increases tear resistance and reduces the chance of rot compared with mixed or recycled blends.
• Reinforced Edges: Reinforced hems protect the perimeter from tearing when tensioned for long periods or during windy conditions.
• Metal Grommets: Metal grommets spaced every 36 in allow secure attachment using rope or bungee cords and make setup simple for roofs, boats, or patio covers.
• Weatherproof Performance: The tarp is waterproof and UV resistant so it can be used year-round to shield items from sun, rain, and snow.
• 10 x 12 Weave Count: A denser weave contributes to the tarp's weight and perceived durability for heavier duty uses like roof coverage or pool protection.

Who It's For

This tarp is aimed at homeowners, contractors, campers and boat owners who need an economical, reliable cover to protect equipment, outdoor furniture, or a temporary roof patch. It is useful where finished, predictable sizing matters and where you plan to secure the tarp with ropes or bungees using grommet points.

Those who need ultra-heavy commercial truck tarps or specialized breathable covers for wood curing should look elsewhere; while this tarp is robust for general purpose use it sits in the heavy-duty consumer category rather than professional-grade, multi-season commercial tarpaulin.

Pros & Cons

Pros

• Durable feel from 100% virgin polyethylene and a solid 10 x 12 weave count that resists tears in typical outdoor use.
• Finished 20 x 30 size provides predictable coverage without unpleasant surprises.
• Reinforced edges and metal grommets every 36 in make securing the tarp straightforward and reliable.

Cons

• Some users report occasional rips under extreme strain, so it is not a substitute for purpose-built commercial truck tarp material.
• The 5 mil thickness balances weight and durability but heavier applications may require thicker alternatives.
