Large Waterproof Tarp 20ft x 35ft - Heavy Duty 5 Mil Protective Cover

In this review the Large Waterproof Tarp 20' x 35' is judged as a pragmatic, no-nonsense cover for outdoor protection; it is best for homeowners and small operators who need a large, easy-to-deploy shield against rain and sun. The bottom line: this tarp stands out for its waterproof and UV-resistant material that reliably keeps gear dry, while being light enough to move around. It is not a precision industrial tarp, but for general-purpose coverage of equipment, pools, boats and campsite ground sheets it delivers strong performance for the price.

Key Features

• Extra thick material: The 5 mil construction provides improved tear resistance and durable protection for stored items and equipment.
• Waterproof and UV resistant: The treated plastic repels heavy rain and reduces sun damage when used as a canopy or cover.
• Reinforced hem with rope: The rope in the hem boosts rip resistance so the tarp holds up better under tension when tied down.
• Rust-proof grommets every 36 in: Grommets placed along the hem allow secure fastening and straightforward installation for long spans.
• Multipurpose use: Sized at 20 ft x 35 ft it can cover boats, RVs, grills, woodpiles or serve as a camping ground sheet for large groups.
• Lightweight handling: Despite its heavy duty intent, the tarp stays manageable for one or two people to position and secure.

Who It's For

This tarp suits homeowners who need a large, economical cover for seasonal storage, backyard projects and storm protection, and for contractors who want a quick protective layer over equipment or materials. It is also useful for campers needing a large ground sheet or shade canopy.

Those seeking an ultra-heavy industrial tarp for constant, abrasive contact or high-load lifting should look elsewhere; the construction is robust for general outdoor protection but some buyers described the feel as lighter than commercial-grade canvas alternatives.

Pros & Cons

Pros

• Good waterproof performance that keeps rain and snow off stored items.
• Large 20 ft x 35 ft size covers wide areas without seams.

Cons

• Some users report mixed impressions of thickness; it may not match heavier industrial tarps for extreme abrasion.
• The 5 mil material can feel lightweight compared with canvas-style covers for long-term UV exposure.
