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

In this review the Tarpco Safety heavy duty 7 mil tarp is evaluated as a straightforward, no-nonsense cover for outdoor protection. It is aimed at homeowners, contractors and campers who need a large, durable sheet that resists water, UV and tearing, and the single biggest reason to buy is its long-lasting construction using 100% virgin polyethylene and reinforced edges that hold up when tied down.

Key Features

• Finished size: The listed dimensions are full finished size so buyers receive the full 20 x 40 tarp rather than a smaller trimmed product.
• 100% virgin polyethylene: Pure, non-recycled material delivers a thicker, more weatherproof sheet that resists rot and prolonged exposure.
• Reinforced edges: Sewn or reinforced hems reduce fraying and concentrate strength where the tarp is tied off.
• Strong grommets: Metal grommets every 36 in allow secure tie-downs with rope or bungee cords for wind resistance.
• Weatherproof performance: The tarp is waterproof and UV resistant so it can protect roofs, boats and outdoor furniture through sun, rain and snow.

Who It's For

This tarp works well for homeowners protecting patios, pools, furniture and temporary roof patches, and for outdoors people who need a reliable camping or gear cover. Landscapers and installers who need large sheets for ground cover or temporary shelters will also appreciate the durability.

Those who need ultra-lightweight or highly breathable fabrics, printed covers, or very small custom sizes should look elsewhere; this is a heavy, utilitarian poly tarp intended for protection rather than fine finishing or specialized fabrics.

Pros & Cons

Pros

• Durable construction from 100% virgin polyethylene provides better tear and rot resistance than mixed-material tarps.

• Performs well as a waterproof, UV resistant cover for a range of outdoor uses.

Cons

• The 7 mil thickness is heavy but some customers note mixed impressions of thickness versus extreme winter demands.

Specifications
