Cartman Extra Thick 20 Mil 20x40 Feet Brown Poly Tarp (Finished Size) — UV Resistant, Waterproof, Reinforced Edges
Product description
If you’re covering things outdoors, you’ve probably learned the hard way that “mostly waterproof” tarps don’t always hold up once wind, sun, and real weather show up. The Cartman Finished Size 20x40 Feet Extra Thick 20 Mil Brown Ultra Heavy Duty Poly Tarp is built for that problem: strong protection for storage, vehicles, yard items, and more—without getting overly precious about it.
The essentials (what this tarp is for)
This is a multipurpose poly tarp designed to protect outdoor items from rain, moisture, and sun exposure. It’s described as extra thick (20 mil) and made for heavy-duty, everyday use—think covering a car or truck, shielding patio furniture, protecting wood or firewood, or helping keep pool supplies and outdoor storage area items safer from the elements.
One detail that matters in real life: the product is sold by “finished size,” meaning the marked size is the exact finished size you should expect. That’s the kind of wording that can save you from the usual frustration of ordering a tarp and then realizing it’s smaller than you planned.
What stands out day to day
The tarp uses 100% virgin polyethylene (not recycled material), which is positioned as a durability advantage. Over time, cheaper tarps can become brittle, tear easier, or break down when they’re exposed to sun and weather. Here, the pitch is that virgin poly is less likely to fail in those common ways.
Cartman also mentions UV resistance, waterproofing, and wind/rain protection for harsh conditions like rain, wind, and even snow. It’s not presented as a “temporary cover for a sunny weekend,” but more like a utility cover you can rely on when weather turns.
You also get reinforced edges. That’s a practical upgrade because corners and edge points are typically where tarps start to give out first—especially when you’re tying it down, staking it, or letting wind test the seams.

You may want to double-check your expectations based on how you plan to secure it, because even a tough tarp can struggle if it’s not tensioned or anchored properly.
Where it shines vs. more basic covers
If you’re comparing it to thinner, lighter tarps, this one is clearly aimed at buyers who want more resistance to tearing and breakdown. Based on its stated density, weave count, and 20 mil thickness, it’s more in the “serious protection” lane than the “cheap quick cover” lane.
Still, there’s a limitation to keep in mind: a tarp helps protect surfaces, but it won’t magically solve every drainage or setup issue. For example, if water is allowed to pool on top because the cover isn’t pitched or tied down correctly, any tarp—no matter how waterproof—can become a hassle.
Practical usage examples (so you can picture it)
Imagine you need to cover a motorcycle and keep dust and rain off the seat and controls. With a 20x40 finished size, you’re getting a larger coverage area than smaller utility tarps, so you can wrap and secure more effectively. Or picture storing firewood under partial shelter: you can lay the tarp as a protective cover to reduce moisture exposure while keeping the wood from getting directly hit by rain.
It’s also listed for things like vehicles, patio/cabins, outdoor furniture, pools, camping, and picnics—basically, if your goal is “shield from outdoors,” this is the kind of tarp that fits that mindset.
Care and storing tips (quick but useful)
To get the most out of a heavy-duty poly tarp, store it flat or loosely folded rather than tightly creased for long periods. Before storage, letting it dry helps prevent lingering moisture. Also, keep an eye on the tie-down points and edges over time—reinforced edges are a big strength here, but consistent anchoring is what keeps it performing.
Should you buy it?
It’s a great fit if you want a thicker, UV-resistant, waterproof poly tarp with reinforced edges and you care about getting the exact finished dimensions (20x40 feet) instead of guessing. It makes sense if you’re covering outdoor items like vehicles, yard storage, wood, or furniture and you expect real weather—not just light shade.
It might not be a great match if you only need a short-term cover, or if you’re looking for something that handles pooling water effortlessly in any setup. Also, if you’re working with a smaller space where 20x40 feels oversized, you may end up with extra material that’s harder to tension.
