20 x 20 Ft. All-Purpose Poly Tarp - Reversible Waterproof Protection

In this review the Kotap 20 x 20 ft. all-purpose tarp is evaluated for general coverage and lightweight protection needs; the bottom line is that it suits anyone seeking a versatile, reversible waterproof sheet for camping, storage, or temporary repairs. The finished size of 19 ft. x 19 ft. 6 in. makes it especially useful when a near-19 ft. span is required, and the tarp's 5-mil thickness provides a balance of affordability and tear resistance that worked for the reviewer in routine outdoor tasks.

Key Features

• Finished Size: The tarp arrives as 19 ft. x 19 ft. 6 in., which is the most accurate measure to plan coverage for boats, woodpiles, or shelters.
• Material Construction: Tightly woven and coated polyethylene offers tear resistance and a waterproof surface for general outdoor protection.
• Reversible Design: Two-color reversible finish gives added versatility for blending into different environments or marking covered areas.
• Hardware and Reinforcement: Rustproof aluminum grommets spaced every 3 ft. and on each corner, plus heat-sealed edges and polyethylene rope, improve tie-down security and edge durability.
• Functionality: At 5-mil thickness the tarp is lightweight and easy to handle for applications like camping ground cover, temporary repairs, and painting drop sheets.

Who It's For

This tarp fits homeowners, campers, and hobbyists who need a large, cost-effective cover for boats, woodpiles, patio furniture, or temporary shelter. The reversible brown/green finish helps it serve in both recreational and practical roles like tent coverage or pool protection.

Those who need heavy industrial protection or long-term, daily exposure in extreme conditions should look at heavier-duty options; while the 5-mil construction is durable for many tasks, customers expecting thick commercial-grade longevity may prefer a heavier tarp.

Pros & Cons

Pros

Cons

• Some users report mixed impressions of durability and thickness, so it may feel light compared with heavy-duty alternatives.
• Water resistance is generally good but has received mixed feedback in prolonged wet conditions.
