GUARD SHIELD Tarp 20x20 ft 12mil Heavy Duty Waterproof - Extra Large

In this review of the GUARD SHIELD 20x20 ft tarp, the bottom line is simple: it is best for homeowners and campers who need a heavy, reusable cover that resists water and provides quick shelter. The single biggest reason to buy is the tarp's 12mil thickness and woven, double-sided polyethylene construction, which delivers a noticeably robust feel compared with thin utility sheets. The review examines how those construction details translate to real-world uses like protecting equipment, covering a pool, or serving as emergency shelter.

Key Features

• 12mil thick construction: The heavy-duty thickness provides stronger puncture resistance and feels substantially more durable than lightweight tarps.
• Double-sided woven polyethylene: A coated weave on both sides gives consistent waterproofing and a tougher surface that sheds water and dirt.
• Heat sealed seams and rope hem: Reinforced edges reduce seam failure and make it easier to tie down without tearing the perimeter.
• Rustproof aluminum grommets every 18 in: Frequent grommets allow secure anchoring and even load distribution to prevent stress points.
• Portable and washable: The tarp packs down for transport, can be rinsed clean, and is intended for multiple uses across seasons.

Who It's For

The tarp suits homeowners, landscapers, and campers who need a versatile cover for pools, boats, vehicles, firewood, or garden equipment and want something thicker than a basic utility sheet. It is also useful for emergency roof patches, truck bed covers, and temporary shade when frequent reuse and decent weather resistance are priorities.

Those who should look elsewhere include users who require reinforced tear-proof industrial tarps for constant heavy abrasion or professional-grade canvas for long-term UV resistance; likewise, buyers seeking custom-fitted covers or very light, low-cost one-time tarps may prefer other options.

Pros & Cons

Pros

• Heavy 12mil thickness offers solid protection and a reassuringly durable feel.
• Woven, double-coated polyethylene and heat sealed seams improve waterproofing and seam strength.
• Rustproof aluminum grommets every 18 in make securing loads straightforward and flexible.
• Portable, washable, and reusable for many outdoor applications from camping to equipment cover.

Cons

• The tarp can still tear under severe abrasion or sharp objects, so it is not invulnerable to punctures.
• The standard green color and general cut are not tailored to custom-fit jobs where a precise size or finish is required.
