Blue 12 x 20 Heavy Duty 20 Mil Tarp Cover - Waterproof UV Resistant

In this review of the Blue 12 x 20 heavy duty tarp, the bottom line is clear: this tarpaulin is aimed at homeowners and outdoor users who need a dependable, full-size cover that withstands weather and heavy use. The standout reason to buy is the combination of a finished-size panel and thick, 100% virgin polyethylene construction, which together deliver reliable protection for roofs, boats, patio furniture and camping setups without the common shortfall of actual delivered dimensions.

Key Features

• Finished size: The tarp is sold at its full finished dimensions so buyers get the stated 12 x 20 coverage without losing inches to hemming or trimming.
• 100% virgin polyethylene: Made from non-recycled material, the tarp feels heavier and resists rot and breakdown better than mixed-material sheets.
• Reinforced edges: Hemmed borders increase tear resistance at stress points so corners and sides hold up when tied down.
• Metal grommets every 18 in: Regularly spaced grommets make it simple to secure with rope or bungee cords and distribute tension more evenly.
• Weatherproof and UV resistant: The tarp is rated to withstand rain, sun and seasonal weather, offering multipurpose protection year-round.
• 16 x 16 weave count: A dense weave contributes to puncture and tear resistance while keeping the tarp flexible enough for handling.

Who It's For

This tarp is best for homeowners, campers, and small-boat owners who need a reliable, larger cover that truly measures the advertised 12 x 20 size and can be tied down securely. It suits tasks like roof patching, covering outdoor furniture for winter, creating a temporary shelter, and protecting gear during transport.

Those who need ultra-heavy industrial tarps for constant commercial hauling or expect complete invulnerability to sharp edges should consider thicker or specialized truck-grade covers; similarly, buyers wanting very lightweight, single-season covers for occasional backyard use might find this tarp heavier than necessary.

Can I use bungee cords with the grommets?
