Tarpco Safety Heavy Duty 7 Mil Tarp Cover 20 x 40 - Waterproof, UV

In this review of the Tarpco Safety Heavy Duty 7 Mil Tarp Cover 20 x 40 we look at who benefits most and the single biggest reason to buy: reliable, year-round protection. For homeowners, contractors and outdoor enthusiasts who need a large, durable tarp, this model stands out because it uses 100% virgin polyethylene and a finished sizing policy so the tarp delivers the full 20 x 40 footprint without surprises. The opening impression is of a heavy, well-finished sheet that resists tearing and sheds water and sun for extended outdoor use.

Key Features

• Finished size: The tarp is sold at its stated dimensions so buyers receive the full 20 x 40 size rather than a smaller finished product.
• Virgin polyethylene construction: Made from 100% virgin material, the tarp is built to resist rot and premature breakdown compared with mixed or recycled alternatives.
• Reinforced edges and grommets: Metal grommets every 36 in combined with strengthened hems let you tie the tarp down securely and reduce tear propagation at attachment points.
• 7 mil thickness and 12 x 10 weave: The heavy weave and thickness provide a durable barrier against punctures and abrasion for practical outdoor protection.
• Weatherproof and UV resistant: Treated to resist UV damage and fully waterproof, the cover is intended for year-round use in rain, snow and sun.
• Multipurpose design: Large coverage makes it suitable for roofs, boats, pools, patio furniture and temporary shelter or ground cover while painting.

Who It's For

This tarp is a solid choice for homeowners who need a dependable, large sheet to protect outdoor furniture, cover a boat or patch a roof temporarily, as well as for campers or contractors needing a heavy-duty ground or material cover. The finished-size promise is especially useful for projects where precise coverage matters.

People who need a lightweight, compact tarp for backpacking or a very long-term industrial cover (where thicker industrial fabrics are preferred) should look elsewhere; this 7 mil poly sheet trades packability and ultra-heavy industrial strength for broad versatility and value.

Pros & Cons

Pros

• Durable 100% virgin polyethylene resists tearing and rot under normal outdoor conditions.
• Reinforced edges and metal grommets every 36 in make secure tie-downs practical and reduce stress at attachment points.
• Waterproof and UV resistant construction holds up to rain, snow and sun for season-long use.
• Finished sizing means you get the full advertised 20 x 40 coverage without undersized surprises.

Cons

• At 7 mil thickness it is heavy and less packable than ultralight tarps, and some users may expect a thicker industrial-grade fabric for constant, multi-year exposure.
