Core Tarps Heavy Duty 10 Mil Tarp Cover 12 x 20 - Waterproof UV

Our review of the Core Tarps heavy duty 10 mil tarp cover finds it best suited to homeowners and outdoorspeople who need a reliable, year-round protective sheet. The single biggest reason to buy is the combination of finished sizing and 100% virgin polyethylene construction, which delivers a tarp that is the advertised size and feels noticeably thicker than standard mixed-material tarps. For uses from temporary roof patches to covering boats and patio furniture, this tarp balances durability with useful attachment points.

Key Features

• Finished size: You get the full 12 x 20 finished dimensions instead of a tarp that is short a few inches, which makes planning coverage easier.
• 100% virgin polyethylene: The pure material gives the tarp better tear resistance and longevity compared with mixed or recycled blends.
• Reinforced edges: Heavy hemmed edges reduce fraying and reinforce the perimeter for longer life under tension.
• Metal grommets every 24 in: Strong grommets allow secure tie-downs with rope or bungee cords without pulling out the material.
• UV resistant and waterproof: The fabric resists sun degradation and sheds rain, snow, and wind for multi-season protection.

Who It's For

This tarp is a good fit for DIY homeowners who need dependable weather protection for roofs, outdoor furniture, pools, or boats and want predictable sizing when ordering. It is also useful for campers who want a heavy, waterproof ground or canopy tarp that will tolerate repeated use.

Those needing a lightweight, ultralow-cost disposable cover for short-term single events may prefer a thinner, cheaper option, and professionals who require industrial-grade truck tarps with specialized coatings or stitching should review higher-spec commercial tarps instead.

Pros & Cons

Pros

• Finished sizing removes guesswork and makes coverage planning straightforward.
• Thicker 100% virgin polyethylene construction feels durable and resists tearing in normal use.
• Reinforced edges and metal grommets every 24 in provide reliable tie-down points.

Cons

• Some users report occasional rips under extreme strain, so it is not a substitute for specialized industrial truck tarps.
