20 ft x 12 ft White 20 Mil Heavy Duty Tarp - Waterproof, UV Guard

In this review of the 20 ft x 12 ft white 20 mil tarp, the bottom line is simple: this cover is for anyone who needs a full-size, heavy-duty poly tarp that stays true to its advertised dimensions and stands up to weather. The reviewer found the finished size statement meaningful because the tarp arrives the full 12 by 20 ft rather than smaller, and the use of 100% virgin polyethylene gives it a solid, weighty feel that most casual tarps lack.

Key Features

• Finished size: You get the full 12 by 20 ft coverage as advertised, so planning a cover or repair is straightforward without guessing for missing inches.
• 100% virgin polyethylene: The pure material construction increases tear resistance and reduces the chance of rot compared with mixed recycled blends.
• Reinforced edges: Double-stitched borders hold shape under tension and help prevent fraying when tied down for long-term outdoor use.
• Metal grommets every 18 in: Heavy-duty grommets allow secure fastening with rope or bungee cords across the entire perimeter for reliable tie-down points.
• Weatherproof and UV resistant: The tarp sheds water and resists sun damage, making it usable year-round for roofs, boats, patios, or camping shelters.

Who It's For

This tarp is best for homeowners, contractors, and outdoorsmen who need dependable coverage for large items: roof patches, boat or pool covers, patio furniture protection, or temporary work shelters. The full finished size and heavier 20 mil body suit projects that demand a tarp more substantial than thin multipurpose sheets.

Those who need an ultra-heavy commercial truck tarp or a fashion-minded canopy fabric should look elsewhere; while durable, this polypropylene tarp is utilitarian and focused on protection rather than aesthetics or indefinite abrasion resistance in industrial settings.

Pros & Cons

Pros

• Thick, weighty feel from 20 mil polyethylene that resists tearing in normal outdoor use.
• Accurate finished size avoids surprises when covering large objects.
• Reinforced edges and closely spaced metal grommets provide solid tie-down options.

Cons

• Some users report rips under extreme abrasion or sharp edges, so protection or padding is advised on rough surfaces.
• Thickness can vary slightly between units, so weight and feel may differ a bit from one tarp to another.
