Blue 20 x 20 Heavy Duty 7 Mil Poly Tarp Cover - Waterproof UV

Our review of the Blue 20 x 20 Heavy Duty 7 Mil Poly Tarp finds it best suited for homeowners, DIYers and outdoor enthusiasts who need a reliable, multipurpose cover that resists weather and wear. The single biggest reason to buy is the combination of a true finished size and durable 100% virgin polyethylene construction, which means you get the full 20 x 20 tarp and a material that will not rip or rot easily. This review focuses on real-world durability, fastening options and everyday applications like roof patches, patio protection and camping sheltering.

Key Features

• Finished Size: The tarp is sold as a full 20 x 20 finished size so buyers receive the advertised dimensions without missing inches at the edges.
• 100% Virgin Polyethylene: Made from pure non-recycled polyethylene for stronger tear resistance and longer life compared with mixed-material tarps.
• Reinforced Edges: Reinforced hems help prevent fraying and extend the tarp life when tied down or exposed to abrasion.
• Strong Grommets: Metal grommets placed every 36 in allow secure tie-downs with rope or bungee cords for reliable anchoring in wind and rain.
• Weatherproof and UV Resistant: Designed to be waterproof, weatherproof and UV resistant so it can be used year-round on roofs, boats, pools and outdoor furniture.
• 12 x 10 Weave Count: A dense weave that contributes to the tarp's overall strength and resistance to tearing under load.

Who It's For

This tarp is ideal for homeowners covering patio furniture, contractors needing a temporary roof patch, and campers or boat owners who want a heavy-duty, waterproof sheet. The true finished size is particularly useful for projects where precise coverage matters.

It may be less suitable for users who require a lightweight, breathable fabric for long-term tarpaulin installations or those wanting ultra-fine finishes; for breathable or decorative canopy use a fabric-specific cover instead.

Pros & Cons
