Large Waterproof Tarp 20 Mil Thick Heavy Duty - 12ft x 20ft 2 Pack

In this review the Large Waterproof Tarp 20 Mil Thick is evaluated as a budget-friendly, heavy-duty cover for outdoor gear and shelter needs. It is best for homeowners, campers and anyone needing a large, multipurpose sheet to protect items from rain and UV exposure; the single biggest reason to buy is its combination of extra-thick material and reinforced hems with grommets that make secure covers practical without adding excessive weight.

Key Features

• Premium Quality: The 20 mil thickness provides a balance of extra durability and manageable weight so it can be moved and positioned by one or two people for tasks like covering machinery or woodpiles.
• Superior Protection: UV-treated and waterproof material helps keep equipment, tents or pools dry during heavy rain and reduces sun damage over time.
• Multipurpose Use: The large 12ft x 20ft size works for cars, motorcycles, grills, canopy tents or as a ground sheet when camping, offering flexible protection for many projects.
• Expert Construction: Reinforced hems with a rope and rust-proof grommets every 36 in allow for secure tie-downs and improved tear resistance on anchor points.
• Value Promise: The package is a 2 pack, which gives extra coverage or a spare tarp and is backed by a 30-day return promise for added purchase confidence.

Who It's For

The tarp is aimed at DIYers, homeowners and outdoor enthusiasts who need a large, water-resistant cover that is simple to deploy for seasonal storage, emergency repairs or campsite use. Its size and grommet spacing suit those who want to lash a tarp over a boat, RV items, or a temporary roof patch without specialist tools.

Those requiring heavy industrial-grade tarps for constant, extreme abrasion or prolonged UV exposure may want a canvas or thicker commercial solution; some customers reported mixed results on long-term tear resistance, so professionals with continuous heavy use should consider more specialized products.

Pros & Cons

Pros

• Extra-thick 20 mil material offers solid waterproofing and decent tear resistance for general outdoor tasks.
• Reinforced hem with rope and rust-proof grommets every 36 in makes secure anchoring straightforward.
• Large 12ft x 20ft size and 2 pack format deliver good coverage and value for multiple jobs.
• Lightweight enough to handle without heavy equipment, useful for quick covers and camping.

Cons

• Some users report mixed durability under heavy or repeated abrasive use, so it may not match the strongest commercial-grade tarps.
• Thickness perception varies by user, so expectations for extreme heavy-duty performance should be tempered.
