Core Tarps Classic 5 Mil Tarp Cover 30 x 70 - Waterproof, UV Resistant

In this review the Core Tarps Classic 5 Mil Tarp Cover is evaluated for everyday outdoor protection and jobsite use. The bottom line: this tarp is best for someone who needs a sizeable, no-frills, heavy plastic cover that resists water and UV and arrives at the stated finished size; the single biggest reason to buy is its use of 100% virgin polyethylene and reinforced edges, which give the tarp a substantial feel and make it reliable for covering roofs, boats, patio furniture, or temporary shelters.

Key Features

• Finished size: The tarp is sold at the full finished dimensions so buyers get the advertised 30 ft x 70 in coverage without the common shortfall some sellers have.
• 100% virgin polyethylene: Using pure, non-recycled material makes the sheet thicker and more resistant to tearing, rot, and long-term degradation compared with mixed-material tarps.
• Reinforced edges: The sewn and reinforced perimeter helps the tarp maintain shape and prevents edge fraying when tied down or under tension.
• Metal grommets: Grommets placed every 36 in provide secure anchor points for rope or bungee cords and simplify installation for covers and canopies.
• Weatherproof performance: The tarp is waterproof and UV resistant so it blocks rain and sun exposure across seasons for outdoor storage and temporary repairs.
• Multipurpose: The tarp works for many tasks, from roof patches and boat covers to campsite shelters and drop cloths for painting.

Who It's For

The Core Tarps Classic 5 Mil is a practical choice for homeowners, contractors on a budget, and outdoor hobbyists who need a simple, heavy poly tarp to protect equipment, cover wood piles, or create a shelter. Its finished sizing and heavier feel suit users who value getting the full advertised dimensions without surprises.

Those who should look elsewhere include buyers needing a very lightweight tarp for backpacking or a heavy canvas alternative for long-term UV-heavy exposure where higher-grade, thicker materials are required; also, if you require very frequent tie-downs under extreme stress, consider options with closer grommet spacing or reinforced corner plates.

Pros & Cons

Pros

• Durable virgin polyethylene gives a substantial, tear-resistant sheet suited to roof or boat covers.
• Reinforced edges and metal grommets every 36 in make fastening straightforward and more secure than unreinforced tarps.
• Waterproof and UV resistant construction protects items through rain, sun, and light snow.

Cons

• Grommets have occasional reports of tearing out under extreme load, so heavy-strain anchoring requires care.
• At 5 mil this is not as heavy as some industrial-grade tarps, so very long-term or professional continuous exposure may need thicker material.

Frequently Asked Questions

Is the listed size the actual usable size?
Yes; the tarp is sold as a finished size so the 30 x 70 dimensions reflect the usable sheet rather than being reduced by hemming.

Can I leave this tarp outside year-round?
The tarp is waterproof and UV resistant for seasonal outdoor use, but long-term continuous exposure in extreme conditions may shorten life compared with thicker, industrial tarps.

Are the grommets strong enough for heavy winds?
The metal grommets are spaced every 36 in and work well for most tie-downs, though a few users report grommet tearing under extreme loads, so reinforce corners if you expect heavy strain.
