8 Mil White Tarp 16 x 20 - Heavy Duty Waterproof Poly Tarp

In this review the 8 mil white tarp 16 x 20 is evaluated for people who need a reliable, heavy duty cover for seasonal projects and outdoor storage; the bottom line is that it delivers strong weather protection in a finished-size tarp that is ready to use. The reviewer found the standout reason to buy is the use of 100% virgin polyethylene and reinforced edges, which together make a tear-resistant, waterproof cover suitable for roofs, boats and patios without surprises in final dimensions.

Key Features

• Finished size: The tarp is supplied at the full chosen dimensions so customers receive an actual 16 x 20 ft sheet rather than a smaller cut size.
• 100% virgin polyethylene: Using non-recycled material increases durability and helps the tarp resist tearing, rot and premature breakdown compared with mixed-material alternatives.
• Reinforced edges: Heavy hemmed borders reduce fraying and help the tarp hold tension when tied down for long-term outdoor use.
• Metal grommets every 24 in: Grommets spaced at 24 in intervals make it straightforward to secure the tarp with bungee cords or rope across a wide span.
• Weatherproof and UV resistant: The poly construction provides waterproof protection and UV resistance so the tarp can be used year round in sun, rain or snow.

Who It's For

The 8 mil 16 x 20 white tarp is best for homeowners, contractors or outdoorsmen who need a large, dependable cover for items like roofs, patio furniture, boats and pools where a full-size tarp is essential. Its heavyweight feel and reinforced edges suit jobs that require repeated tensioning and longer exposure to the elements.

People who want a lightweight, finely finished aesthetic or who require grommet spacing different than 24 in should consider other options; similarly, those needing a thinner, cheaper tarp for one-time light duty might find the 8 mil construction more than necessary.

Pros & Cons

Pros

• Durable 100% virgin polyethylene resists tearing and rot for longer service life.
• Finished dimensions guarantee an actual 16 x 20 ft tarp without unexpected shortages.
• Reinforced edges and metal grommets every 24 in make secure tie-downs easy.
• Waterproof and UV resistant, suitable for year-round outdoor use.

Cons

• At 8 mil thickness it is heavier and less packable than thin economy tarps, which can be a downside for backpacking or very compact storage.
• Some users have reported rips in heavy abuse situations, so extreme-duty applications may require a specialized truck tarp.
