Tarps Heavy Duty Waterproof 20x40 12 mil Thick Tarp - Weatherproof

In this review of the Tarps Heavy Duty Waterproof 20x40 12 mil tarp, the bottom line is simple: this is a large, no-nonsense cover for anyone who needs a tough, multiuse tarp at a reasonable price. It is best for campers, homeowners protecting pools or equipment, and for light cargo or RV cover tasks where a big, waterproof barrier is needed. The single biggest reason to buy is the combination of generous 20 ft by 40 ft size and a 12 mil thickness that aims to resist weather and UV exposure while offering reinforced edging for longer service life.

Key Features

• Generous size: The 20x40 ft dimensions provide ample coverage for large boats, RVs, pools or campsite shelter without awkward seams.
• 12 mil thickness: Thicker than many general-purpose tarps, this material seeks to add durability and improved puncture resistance in outdoor conditions.
• Weatherproof protection: The tarp is waterproof and UV resistant, helping protect covered items from rain, sun damage and dust buildup.
• Reinforced construction: Reinforced edging and quality stitching aim to reduce edge fraying and extend usable life under tension.
• Rust-proof grommets: Metal grommets placed every 18 in make it straightforward to secure the tarp and distribute tie-down stress.
• Multipurpose use: Designed for camping, tent covers, boats, RVs, cars and pool protection, this tarp covers a wide range of outdoor needs.

Who It's For

This tarp is a practical choice for outdoor enthusiasts, homeowners and handypersons who need a large, waterproof cover without specialty fittings. Campers who build ground shelters or shade can benefit from the size and rust-proof grommets, and property owners can use it as a temporary pool, boat or equipment cover.

It is less suitable for users who need a lightweight backpacking tarp or for extremely heavy commercial workloads where industrial-grade reinforced tie points are required; those users should consider bespoke heavy-duty or professional covers with guaranteed load-tested fittings.

Pros & Cons

Pros

• Large 20x40 ft coverage handles big items and group campsite needs without seams.
• 12 mil material and UV resistance offer better-than-basic protection against sun and rain.
• Reinforced edges and regular rust-proof grommets make installation and securing simple.
• Versatile for camping, RVs, boats, cars, pools and general yard work.

Cons

• Some users report mixed durability around grommet areas, so heavy constant tension can risk tearing.
• Perceptions of thickness vary; some expect heavier industrial tarps for very high-abrasion tasks.

Frequently Asked Questions

Will this tarp keep items dry in rain?
The tarp is waterproof and designed to keep items dry in typical rain; very heavy downpours with standing water should be avoided by angling the tarp for runoff.

How often are the grommets placed?
Rust-proof metal grommets are positioned every 18 in to make securing and tying down the tarp easier and more even.

Is this tarp suitable for long-term UV exposure?
The material is UV resistant for extended outdoor use, but continuous long-term exposure may eventually degrade any tarp; periodic inspection is recommended.
