20 x 35 20 Mil Heavy Duty Tarp Cover - Waterproof UV Resistant

Our review of the 20 x 35 20 mil tarp finds it best suited to homeowners and outdoorsmen who need a heavy, dependable cover for seasonal projects. The single biggest reason to buy is its thick, 100% virgin polyethylene construction, which gives the tarp a substantial weight and tear resistance that makes it practical for roofing patches, boat covers, and camping shelters. The finished size claim is also meaningful: customers get the full 20 x 35 in surface without being shorted by trimmed dimensions, so coverage planning is straightforward.

Key Features

• Finished size: The tarp is cut to the full 20 x 35 in so you receive the stated dimensions for accurate coverage planning.
• 100% virgin polyethylene: Built from non-recycled material for improved strength and resistance to ripping, rot and premature breakdown.
• Reinforced edges: Heavy hems reduce fraying and help the tarp hold shape under tension and extended outdoor exposure.
• Metal grommets every 18 in: Grommets placed at regular intervals make it simple to secure the tarp with rope or bungee cords for stable tie-downs.
• Weatherproof performance: The material is waterproof and UV resistant so it blocks rain and sun damage across seasons.

Who It's For

The tarp is ideal for homeowners, contractors and outdoor enthusiasts who need a substantial cover for roofs, pools, boats or patio furniture and want a tarp that matches the stated dimensions. Its heavier weight and reinforced edges make it especially useful where wind exposure or sharp edges could otherwise compromise a lighter cover.

Those who need an ultra-light, packable tarp for backpacking or who require custom-cut or sewn-in features should look elsewhere; this product is focused on durability and coverage rather than minimal pack size or tailored fittings.

Pros & Cons

Pros

Cons
