PROTARP Extreme Heavy Duty 22 Mil Tarp Cover 20 x 40 - Waterproof, UV

In this review the PROTARP Extreme Heavy Duty 22 Mil Tarp Cover is evaluated as a workhorse tarp for demanding outdoor jobs. It is aimed at homeowners, contractors, and campers who need a large, dependable cover that resists tears and weather; the single biggest reason to buy is its combination of 22 mil thickness and 100% virgin polyethylene construction, which delivers toughness and long-term weather resistance that cheaper, mixed-material tarps typically lack.

Key Features

• Finished size: The tarp is sold at its full finished dimensions so buyers get the exact 20 x 40 coverage without the common shortfall some rivals have.
• 100% virgin polyethylene: Pure, non-recycled material provides consistent strength and rot resistance so the tarp holds up better under repeated use and exposure.
• 22 mil thickness: The extra-thick sheet delivers superior puncture and tear resistance for heavy-duty tasks like roofing, boat covers, or storm protection.
• Reinforced edges and grommets: Metal grommets every 18 in and reinforced hems let you secure the tarp tightly with rope or bungee cords without tearing the edge.
• Weatherproof and UV resistant: Designed to repel water and resist sun damage, it works across seasons for long-term outdoor protection.
• Multipurpose design: Large format and durable build make it suitable for covers, makeshift shelters, painting floors, or protecting outdoor furniture.

Who It's For

The PROTARP 22 mil tarp is ideal for homeowners repairing roofs after storm damage, contractors needing a tough temporary cover on job sites, and outdoorspeople who want a durable shelter or groundsheet. Its heavy build and reinforced edges suit frequent use where puncture resistance and reliable tie-down points matter.

It is less suitable for those who need an ultralight tarp for backpacking or minimalist camping, or buyers who require a custom-fit cover with exact cutouts; for lightweight or precision-fit needs a thinner or custom tarp would be a better match.

Pros & Cons

Pros

• Very durable 22 mil construction resists tearing and punctures in heavy use situations.
• Finished size guarantee means you receive a full 20 x 40 tarp with no unexpected shortfall.
• Strong grommets every 18 in and reinforced hems make secure tie-downs straightforward.
• Good UV and waterproof performance provides seasonal outdoor protection and longevity.

Cons

• At 22 mil and full 20 x 40 size the tarp can be heavy and awkward to handle for a single person.
• Color and pattern are functional rather than decorative if appearance matters.

Yes, PROTARP lists finished size so the 20 x 40 dimension is the actual tarp size you receive.

Yes, reinforced edges and metal grommets every 18 in allow secure tie-downs using rope or bungees with minimal risk of edge tear.

Will it handle long-term sun exposure?
The tarp is UV resistant and designed for prolonged outdoor use, though extreme sun exposure over many years will gradually degrade any polyethylene product.
