RAINDEWAY 10x20 ft Super Heavy Duty Tarp 18 Mil - Weatherproof

In this review of the RAINDEWAY 10x20 ft tarp the bottom line is simple: this is a heavy, no-nonsense cover for anyone who needs long-lasting protection from sun, rain and wind. The single biggest reason to buy is its 18 mil super heavy duty construction with a tight 16 x 16 weave and roughly 9.2 oz per sq yard weight, which gives the tarp real tear resistance and water protection for outdoor equipment, trucks, boats, or temporary shelter.

Key Features

• 18 mil thickness: The heavy gauge material delivers robust puncture and tear resistance so the tarp holds up under rough use.
• Tight 16 x 16 weave: Dense polyethylene fibers reduce water penetration and add durability for long-term outdoor exposure.
• Reinforced edges with metal grommets: Built-in grommets spaced about 18 in apart let you secure the tarp reliably to frames, vehicles, or anchors.
• Reversible brown/gray sides: Either side can face out to match surroundings or reduce visible fading over time.
• UV resistant and weatherproof: Treated to resist sun damage and protect gear from rain, dirt, and sunlight during seasonal storage.
• Finished actual size: The stated 10 ft x 20 ft is the usable finished size, so coverage planning is straightforward.

Who It's For

The RAINDEWAY tarp is aimed at homeowners, contractors, and outdoor enthusiasts who need a dependable, heavy-duty cover for equipment, furniture, small roofs, trailers, or boats. Its weight and reinforcement make it a good choice where wind and abrasion are likely concerns.

Those who need an ultra-light backpacking tarp or a custom-cut aesthetic cover should look elsewhere; this product prioritizes durability and weather resistance over minimal weight or decorative finishes.
