Core Tarps Classic 5 Mil Tarp Cover - Heavy Duty Waterproof Protection

In this review of the Core Tarps Classic 5 Mil Tarp Cover, the bottom line is simple: it is for anyone who needs a heavy, weatherproof sheet for seasonal or temporary outdoor protection. The reviewer found the tarp's single biggest advantage to be its build quality - finished size panels made from 100% virgin polyethylene with reinforced edges and grommets that make it feel more durable and reliable than thinner, recycled alternatives. It is best suited for covering roofs, boats or outdoor furniture where a robust, waterproof barrier is required.

Key Features

• Finished Size: The tarp delivers the full advertised dimensions so there are no surprises when measuring for coverage.
• 100% Virgin Polyethylene: Pure, non-recycled material contributes to tear resistance and reduces the tendency to rot or degrade quickly.
• Reinforced Edges: Reinforced hems add strength at stress points so the tarp holds up better against wind and handling.
• Strong Grommets: Metal grommets every 36 in allow secure tie-downs with rope or bungees to keep the tarp in place.
• Weatherproof and UV Resistant: The material is waterproof and UV treated so it can be used year-round in sun, rain or snow.

Who It's For

The Core Tarps Classic 5 Mil is ideal for homeowners, contractors and outdoor enthusiasts who need a substantial, multiuse cover for short- to medium-term protection. It works well for covering a damaged roof temporarily, protecting a boat during off-season storage, shielding patio furniture, or creating a campsite shelter thanks to its heavier weight and strong grommet spacing.

Those looking for a permanent roofing solution or an ultra-light packable tarp for long backpacking trips should consider other products. Also, if extreme long-term commercial exposure is required, heavier industrial-grade tarps with additional hardware may be preferable.

Pros & Cons

Pros

• Durable 100% virgin polyethylene gives a noticeably thicker, heavier feel compared with mixed-material tarps.
• Finished size means accurate coverage without losing inches at the edges.
• Reinforced edges and grommets every 36 in make tie-downs straightforward and secure in normal conditions.
• Waterproof and UV resistant for year-round outdoor use.

Cons

• Some users report grommets can tear out under extreme strain, so extra care or additional fastening methods may be needed for prolonged high-wind exposure.
• At 5 mil thickness it is heavier and less packable than ultralight tarps for backpacking.

Frequently Asked Questions

Is this tarp fully waterproof?
Yes. The 100% virgin polyethylene material is waterproof and designed to block rain and snow.

Will the grommets hold in high winds?
The grommets are metal and spaced every 36 in, providing good hold for normal conditions; however, some users report grommet tear-out under extreme sustained strain, so additional reinforcement can help in very windy locations.

Does the listed size reflect the full usable area?
Yes. The manufacturer specifies finished size, so the tarp measures the full advertised dimensions without missing inches at the edges.
