20 Mil White Heavy Duty Tarp 12 x 16 - Waterproof, UV Resistant

In this review of the 20 Mil White Heavy Duty Tarp 12 x 16, the bottom line is simple: this tarp is built for users who need a large, dependable cover that resists weather and wear. The review finds its single biggest selling point is the combination of a true finished size and thick, 100% virgin polyethylene construction, which delivers predictable coverage and long-term durability for outdoor projects and seasonal storage.

Key Features

• Finished Size: The tarp is supplied at the full stated measurement so buyers get the entire 12 x 16 area without missing inches at the edges, which simplifies planning and coverage.
• 100% Virgin Polyethylene: Made from pure, non-recycled polyethylene for consistent thickness and improved tear resistance compared with mixed-material tarps.
• Reinforced Edges: Reinforced hems reduce fraying and distribute tension, making tiedowns more reliable when securing the cover in wind or rain.
• Strong Grommets: Metal grommets spaced every 18 in allow secure attachment with rope or bungee cords and stand up to repeated use.
• Weatherproof Construction: The tarp is waterproof and UV resistant so it protects against sun damage, rain, snow and seasonal exposure for items like roofs, boats, and patio furniture.

Who It's For

This tarp suits homeowners, contractors, and outdoor enthusiasts who need a robust, predictable cover for medium to large items such as plywood shed roofs, boats, patio sets, or gear during storage. The finished-size promise is particularly valuable to anyone who has previously bought tarps that were several inches smaller than advertised.

Those who need custom-cut shapes, lightweight picnic covers, or breathable fabric should look elsewhere; this is a heavy-duty, non-breathable polyethylene tarp intended for protective covering and weatherproofing rather than decorative or ventilation-sensitive uses.

Pros & Cons

Pros

• Durable 20 mil thickness and virgin polyethylene construction make it resistant to tears and rot.
• Finished-size labeling means reliable coverage without unpleasant surprises at delivery.
• Reinforced edges and metal grommets every 18 in make attachment straightforward and secure.

Cons

• Because it is heavy-duty and non-breathable, the tarp can be bulky to handle and store when not in use.
