Patiobay Tarp 12x20FT (14 Mil) Heavy Duty Waterproof Poly Tarp with Grommets
Product description
The essentials
If you need a big waterproof cover that feels built for outdoor abuse, the Patiobay Tarp 12x20FT is aimed at exactly that: heavy-duty polyethylene tarp coverage for pools, outdoor furniture, boats, roofs, and more. On paper, the 14 mil thickness is the headline, and the rest of the design supports that promise with reinforced edges, metal grommets, and extra hem reinforcement.
That said, a tarp like this is only as useful as your setup. If you don’t plan on tying it down well (or you expect it to act like a precision-fit cover), it can still sag or flap in heavy wind. It’s tough material and solid anchoring points, but it’s still a tarp—not a rigid shelter.
Key features that matter in real use
The standout spec here is the 14 mil material thickness. Thicker plastic tends to hold up better when you’re stretching it over uneven surfaces or dealing with day-to-day outdoor exposure. This one is also described as UV resistant and waterproof/weatherproof, so it’s positioned for outdoor storms and harsher conditions.
Next comes the fastening system. You get metal grommets reinforced along the edges, spaced every 23.6 inches. That spacing is practical for threading bungee cords or running a sturdy rope through the tarp so you can pull it taut. Reinforced edges matter more than you’d think: the stress is usually concentrated around where the cords attach.
Finally, the hem is reinforced with poly rope stitched across all sides. Again, that’s the sort of detail that helps reduce tearing and deformation when the tarp is under tension.
What stands out (and where it can fall short)
Where it shines is broad coverage and versatility. At 12x20 feet, it’s the kind of large sheet you can repurpose across a season: covering outdoor items during bad weather, acting as pool coverage, or even laying down floor protection during painting projects. The description also mentions using it as a canopy tent material, which fits the “tarps as utility gear” mindset.
Where you should be cautious is expectations. If you’re trying to replace something custom-fitted (like a purpose-built pool cover or a tight canopy frame), this will feel more like a strong base layer than a finished product. Also, while it’s waterproof, tarps generally perform best when they’re properly tensioned and anchored, otherwise, water can pool or find gaps.
It may not be the best choice if you need a precision-sized cover for a specific device or want a lightweight, packable option for frequent transport.
Practical setup tips before you buy
Before committing, measure the area you’re planning to cover and think about how you’ll secure corners and edges. With grommets every 23.6 inches, you’ll likely want multiple tie points rather than only anchoring a few corners.
A quick example: imagine you’re covering outdoor pool equipment during a rainstorm. Lay the tarp flat, center it over the target area, then pull it tight using bungee cords or rope through the grommets. The reinforced edges give you more confidence that the attachment points won’t become the weak spot after repeated storms.
If wind is a factor where you live, prioritize a taut installation. A tarp that’s loose will flap, and that’s when even durable materials can wear faster.

Who it’s for (and who should skip it)
This tarp makes sense if you want a tough, multipurpose outdoor cover and you’re comfortable securing it with bungee cords or sturdy rope. It’s especially relevant for people who handle seasonal protection tasks—pool season, outdoor storage cover-ups, weather emergencies, or DIY projects where you need a protective layer.
It may not suit you if you need something that is designed to fit one specific item perfectly, or if you’re looking for a very lightweight tarp for frequent travel. If your priority is exact fit and minimal setup, you may end up frustrated.

What can I use it for besides a pool?

Final verdict
If you need a large, heavy duty waterproof tarp for outdoor protection and multipurpose use, the Patiobay Tarp 12x20FT looks like the kind of straightforward workhorse that can hold up—especially thanks to the 14 mil thickness, reinforced edges, and grommet spacing. It’s a solid pick when you plan to tie it down properly and want one sheet that can cover different jobs around your property.
Skip it if you’re expecting a perfectly fitted, lightweight, or low-effort solution. For those situations, you’ll likely want a more specialized approach rather than a general-purpose tarp sheet.
