Core Tarps Classic 5 Mil Tarp Cover 20 x 40 - Durable Waterproof

In this review of the Core Tarps Classic 5 Mil Tarp Cover, the bottom line is simple: this tarp is best for anyone who needs an affordable, heavy-duty sheet to protect roofs, boats, patio furniture or camping gear from sun and rain. The reviewer found the finished size claim accurate, and the 100% virgin polyethylene construction gives the tarp a reassuring weight and feel that translates into real-world protection against weather. If you want a no-frills, weatherproof cover with reinforced edges and widely spaced metal grommets, this tarp delivers on core promises without excess bells and whistles.

Key Features

• Finished Size: The tarp is sold at its full finished dimensions so buyers get the full 20 ft x 40 ft coverage without missing inches at the edges.
• 100% Virgin Polyethylene: Using pure polyethylene makes the material feel thicker and less prone to rot compared with mixed or recycled blends.
• Reinforced Edges: Reinforced hems reduce fraying at attachment points and help the tarp hold shape under tension during wind or rain.
• Metal Grommets Every 36 in: Grommets placed at 36 in intervals make it straightforward to secure the tarp with rope or bungee cords over large objects.
• Waterproof and UV Resistant: The finish repels water and resists UV damage so the tarp can be used year-round for outdoor protection.
• Multipurpose Design: Big enough for roofing, boat covers, pool protection, or creating temporary shelters and floor covers while painting.

Who It's For

The Core Tarps Classic 5 Mil is aimed at homeowners, contractors and outdoor enthusiasts who need a heavy, economical tarp for seasonal protection, temporary repairs or general covering tasks. Its finished sizing and reinforced edges make it a good fit for larger jobs like covering a small roof section or a boat during winter storage.

It is less appropriate for users who require a specialty tarp with super-fine grommet spacing, custom fittings or a guaranteed lifetime outdoors; those buyers should consider heavier industrial-grade options or products with documented long-term warranties.

Pros & Cons

Pros

• Thick, weighty material from 100% virgin polyethylene feels durable in hand and stands up to rain and sun.
• Finished size listing means you receive the full 20 ft x 40 ft coverage without surprises.
• Reinforced edges and metal grommets simplify tie-downs and reduce tearing at stress points.
• Versatile for many uses including roofing patches, boat covers, patio protection and camping shelters.

Cons

• Some users report ripping under extreme strain, so it may not match the longevity of heavy industrial truck tarps in high-stress uses.
• Grommets at 36 in intervals are practical for many jobs but may be too far apart for delicate or highly precise fastening needs.
