CARTMAN Extra Thick 20 Mil Brown Poly Tarp, Finished Size 12x16 Feet, UV Resistant & Waterproof

The essentials first: what this tarp is for

This CARTMAN poly tarp is built as a protective cover for outdoor stuff that you don’t want exposed—whether it’s getting hit with rain, wind, snow, or lots of sun. On paper, it leans toward the heavy-duty end of the tarp spectrum thanks to its extra thick 20 mil construction and reinforced edges, so it’s meant to handle real weather rather than only light, occasional use.

The “finished size” matters here. The product description says the marked size is the exact finished size, meaning when you pick 12x16 feet, you should get a tarp that actually measures out to that finished dimension. That’s a practical detail if you’re trying to cover something with minimal overlap or you want predictable coverage.

Key features that drive real-world protection

A lot of tarps look similar until you think about what you’ll be protecting and for how long. This one is described as using 100% virgin polyethylene (not recycled), which is positioned as a reason it’s sturdy and less prone to tearing, ripping, or rotting.

It’s also marketed as UV resistant, waterproof, and weatherproof, with functions aimed at reducing the impact of harsh conditions on the items underneath. If you’ve ever opened a tarp only to find it stiff, deteriorated, or letting moisture through, this is the direction you’d typically look for—especially for outdoor storage like yard items, wood, firewood, or furniture.

You also get a couple of durability markers in the description: a density of 260 GSM and a 16x16 weave count. Those aren’t guarantees on their own, but they do suggest this tarp is meant to be more than a thin, flexible sheet.

What you’ll notice day to day

• Reinforced edges can help the tarp hold up when it’s being tied down, strapped, or secured around corners.
• The thickness and material choice are aimed at reducing the “paper tarp” feel you get with lighter covers.

Everyday use: where it makes sense

The brand positions it as multipurpose, with examples including covering a truck, car, motorcycle, roof, yard items, cabins, outdoor furniture, swimming pools, wood, firewood, and more. It’s also described as suitable for camping and picnics.

Here’s a concrete scenario: if you’re storing firewood outdoors and you want the cover to take rain and sun without turning into something fragile, a thicker, UV-resistant tarp like this is the type of choice people make. The reinforced edges also help when you’re tying it down so it doesn’t slip as wind changes.

That said, it’s not a miracle fabric. In very windy situations, any tarp can shift if it’s not secured well. So it’s worth planning how you’ll attach it (straps, cords, ties) rather than assuming thickness alone will keep it perfectly in place.

The limits to keep in mind before buying

Extra thick tarps are great when you need coverage and resilience, but they can be harder to handle than lightweight options. Depending on how you plan to store it, the extra thickness can take up more space and may feel less convenient for quick, grab-and-go use.

Also, the description talks about durability and weather resistance, but it doesn’t spell out things like specific temperature ratings, how long UV protection lasts, or how it performs under long-term standing water. If you expect constant water pooling or extreme exposure for months on end, you’ll want to review your own setup and use case carefully.

Mini FAQ

Is the 12x16 feet size the actual finished size?

Yes—according to the listing, the marked size is the exact finished size, so you should receive tarps that match the selected dimensions.

Will it handle rain and UV exposure?

The description states it’s UV resistant, waterproof, and weatherproof for harsh conditions like rain, wind, and snow, with functions aimed at reducing the impact of extreme weather on covered objects.

What kinds of items can it cover?

The listing includes uses like covering a truck, car, motorcycle, roof, yard/cabin items, outdoor furniture, swimming pools, wood, firewood, and also for camping and picnics.

Does reinforced edges mean it’s easier to secure?

It should help with securing and tying down since the edges are reinforced, which can make the tarp less prone to damage at attachment points.

Final verdict

Worth it if you need a thicker, heavy-duty poly tarp with reinforced edges and you’re trying to protect outdoor items from sun and wet weather—especially for storage like wood, yard items, furniture, or vehicles. It’s not the best match if you only need a light temporary cover or if you want something ultra-easy to fold and carry every day. If your priority is true “set it up and cover it for weather” protection, this one fits the brief, just be sure you can secure it properly so it stays put when conditions get rough.
