Large Tarp 12x20 ft 8 Mil Blue Tarp - Durable Waterproof Cover

In this review of the Large Tarp 12x20 ft 8 mil Blue Tarp the bottom line is simple: it is a practical, no-frills cover for common outdoor tasks where water and UV protection matter. The reviewer found it best for homeowners and small contractors who need a dependable, economical tarp for seasonal covers, temporary roof protection, or shielding equipment. The single biggest reason to buy is the combination of a true finished size and practical reinforcement features that make it easy to position and secure without fuss.

Key Features

• 8 mil thickness: Provides a balance of flexibility and strength suitable for general use without feeling overly stiff or heavy.
• Tightly-woven polyethylene: The 10 x 10 weave and roughly 3.6 oz/sq yard weight deliver a waterproof sheet that sheds rain and light debris effectively.
• Metal grommets: Grommets spaced about 35.4 in apart on all sides make anchoring and tying down straightforward and reliable for most jobs.
• Reinforced edges and corners: Extra strength where you need it reduces tearing and helps the tarp hold up better under tension and repeated use.
• UV resistant finish: Built-in UV protection helps prevent rapid sun degradation when used for seasonal outdoor coverage.

Who It's For

This tarp suits homeowners, gardeners, and small-scale contractors who need an affordable, full-size cover for protecting roofs, outdoor furniture, boats, pet cages, and small vehicles from rain, dirt, and sun. It is also handy for camping and temporary projects where a lightweight, easy-to-handle tarp is preferred.

Those who require heavy-duty industrial covers for sustained severe weather, sustained high-wind coastal exposure, or multi-season permanent installations should look for thicker, heavier-duty options intended for long-term professional use.
