RAINDEWAY 12 Mil Heavy Duty White Tarp 12x16 ft - Thick Waterproof

In this review the RAINDEWAY 12 Mil Heavy Duty White Tarp is evaluated for homeowners, campers and DIYers who need a robust weather cover. The bottom line: this tarp is best for anyone who wants an extra thick, UV resistant and reinforced cover that stands up to wind and abrasion; its 12 mil thickness and tightly woven polyethylene construction make durability the single biggest reason to buy. The review focuses on real-world use, covering build quality, grommet spacing and when the tarp may not meet every expectation.

Key Features

• 12 Mil thickness: The extra thick 12 mil construction provides a heavier, more tear-resistant cover than thin utility tarps for longer service life.
• Tightly woven polyethylene: A 14 x 14 weave count and roughly 6 oz per sq yard deliver a dense fabric that resists punctures and abrasion.
• UV resistant finish: The white surface is treated to reduce sun damage so it can protect objects from UV exposure and extend the tarp's useful life outdoors.
• Metal grommets and reinforced edges: Grommets spaced about 17.7 in apart on reinforced hems make secure tie-downs easier and help the tarp hold up in wind.
• Waterproof and weatherproof: The material is designed to shed rain and snow and act as a protective cover for campers, furniture and equipment.
• Full finished size: The listed 12x16 ft size is provided as a usable, full-size tarp for immediate field use without trimming.

Who It's For

The RAINDEWAY 12x16 ft tarp is aimed at homeowners, campers and contractors who need a heavier tarp for recurring outdoor protection, shade sails, or seasonal storage covers. It suits those who value reinforced edges and widely spaced grommets for flexible mounting and long-term strength.

It is less appropriate for situations that demand a lightweight, small emergency cover or where an exact custom-cut size is required; customers who need guaranteed factory-sealed seams for submerged use or military-grade waterproofing should consider specialized covers instead.

Pros & Cons

Pros

• Robust build quality and thickness that resists tears and holds up under wind.
• UV resistant material helps prevent sun degradation and protects items underneath.
• Reinforced edges with metal grommets make it straightforward to secure and reposition.
• Generous finished size that fits common outdoor needs like covering campers and furniture.

Cons

• Waterproof performance is mixed in customer reports, so heavy prolonged ponding or constant immersion may reveal limits.
• Some buyers note the tarp can be slightly larger than expected, which may require trimming or extra tie-downs for a tight fit.
