Kotap 30 x 50 ft 5-mil Poly Tarp - Reversible Waterproof Protection

Our review of the Kotap 30 x 50 ft 5-mil poly tarp finds it most useful for homeowners and outdoor hobbyists who need a large, lightweight cover that balances versatility with economy. The single biggest reason to buy is its finished size and construction: the tarp arrives as a true 28 ft. 10 in. x 49 ft. 2 in. finished piece with heat-sealed edges, reinforced rope, and rustproof grommets every 3 ft., which makes it easy to secure for tarping boats, woodpiles, or temporary jobsite protection.

Key Features

• Finished size: The actual delivered dimensions of 28 ft. 10 in. x 49 ft. 2 in. make planning coverage straightforward and reduce surprises at install time.
• 5-mil thickness: A lightweight but tear-resistant polyethylene construction that keeps the tarp easy to handle while providing solid general-purpose protection.
• Reversible colors: Brown and green reversible finish offers practical camouflage or aesthetic choice depending on the use and setting.
• Durable finishing: All edges are heat-sealed and reinforced with polyethylene rope to reduce fraying and extend usable life when tied down.
• Grommet spacing: Rustproof aluminum grommets every 3 ft. and at corners give multiple secure tie-down points for stable installation.
• Multiple use cases: Designed for camping, pool or boat covers, woodpile protection, drop cover for painting, and other general outdoor tasks.

Who It's For

This tarp is a solid fit for DIYers, campers, landscapers, and homeowners who need a large, economical cover that is easy to carry and fast to deploy. The reversible color and multiple grommets make it practical for temporary protection over boats, firewood, or as a shelter during outdoor projects.

Those who need an ultra-heavy-duty, industrial-grade tarp for prolonged exposure or heavy abrasion should consider a thicker option; the 5-mil weight is lighter than heavy-duty or ultra-heavy-duty tarps and may feel thin for long-term, high-wear applications.

Pros & Cons
