Core Tarps Classic 5 Mil Tarp Cover 20 x 20 - Waterproof, UV Resistant

In this review the Core Tarps Classic 5 Mil Tarp Cover is evaluated as a general-purpose, heavy-duty poly tarpaulin best suited for outdoor protection and temporary shelter tasks. The single biggest reason to consider it is the combination of a finished size and 100% virgin polyethylene construction, which delivers full-sized coverage and a noticeably durable sheet that resists rot and moisture better than mixed-material tarps. For users who need a reliable, weatherproof cover for roofs, boats, patios or camping shelters, this tarp answers the core needs without unnecessary extras.

Key Features

• Finished Size: The tarp is sold as the full finished size so buyers get the true 20 x 20 coverage rather than a tarp that is a few inches short.
• 100% Virgin Polyethylene: The use of pure, non-recycled polyethylene provides a thicker, more tear-resistant fabric that is less likely to rot or degrade quickly.
• Reinforced Edges: Reinforced hems increase edge durability and reduce fraying when the tarp is tied down or subject to wind shear.
• Metal Grommets Every 36 in: Sturdy metal grommets placed every 36 in allow straightforward tie-downs with rope or bungee cords for secure anchoring.
• Waterproof and UV Resistant: The tarp sheds water and offers UV resistance so it can be used year-round for wet or sunny conditions without immediate breakdown.
• 10 x 12 Weave Count: A tight weave improves tear resistance and helps the material hold up to repeated outdoor use.

Who It's For

The Core Tarps Classic 5 Mil is a good match for homeowners, contractors and campers who need a dependable, economical tarp to cover equipment, protect a temporary roof patch, or create a shelter. Its full finished size is particularly useful when precise coverage is required for boats, pools or patio furniture.

It may not be the right choice for long-term, permanent covering where marine-grade or heavy truck canvas is required, or for users who need grommets spaced closer than 36 in for fine-tuned fastening. Those seeking decorative or breathable fabric covers should look elsewhere.

Pros & Cons

Pros

• Durable 100% virgin polyethylene construction provides strong resistance to tearing and rot.
• Finished size means accurate 20 x 20 coverage without surprises at delivery.
• Reinforced edges and metal grommets make tie-downs simple and reliable for most jobs.
• Waterproof and UV resistant for year-round outdoor protection.

Cons

• Some users report occasional rips under extreme stress, so it is not a substitute for specialized heavy-duty industrial tarps.
• Grommets spaced at 36 in may be too far apart for projects that require very tight fastening.
