SpacEver Spacever Heavy Duty Tarp (20x40 FT, 12 Mil Thick) for Outdoor Pool Roof Tent, Firewood & More

What it is and why people buy it

The Spacever Tarp Heavy Duty 20x40 FT is a heavy-duty outdoor tarp meant for covering big areas where you want basic protection from weather. On paper, it’s built around a thicker profile (12 mil) and a sheet designed to hold up to day-to-day use outdoors, including things like roof-tent coverage for a pool and practical cover for items such as firewood.

You’ll also see it described with features that matter in real use: it’s positioned as waterproof, it includes grommets for fastening, and it’s said to be UV- and tear-resistant. If your current cover feels too thin or flaps around too easily, this is the type of upgrade that makes sense—thicker fabric usually holds up better against minor abuse, wind, and repeated setup.

That said, the limited info you have here (no stated dimensions for grommet spacing, no weight per tarp beyond the brief “140 g” note, no mention of waterproof rating) means you should sanity-check expectations. A tarp like this can be very helpful, but it’s not magic: how tight you pitch it and how you secure it will make or break performance.

Key points

This is a large-format, heavy-duty tarp focused on outdoor covering. The highlights are the 12 mil thickness, waterproof positioning, UV and tear resistance, and the presence of grommets so you can tie it down instead of relying on flimsy clips. The included plastic cover angle suggests the brand is aiming for easier storage/protection of the tarp when it’s not in use.

Where it really earns its keep is the “I need coverage, not just decoration” scenario: pool roof-tent style setups, keeping wood covered, or sheltering gear during messy weather. Depending on how you use it, it can be a one-stop cover that reduces the amount of improvising you do with smaller pieces.

Where it stands out in everyday use

Thicker tarps tend to behave more confidently in the field—less limp, fewer “it tore at the corner” moments, and better resistance to stretching when you cinch it down. Grommets are also a big deal because they change the whole fastening experience: you can use rope, bungee-like ties, or similar methods to tension the tarp.

Here’s a practical example: imagine setting up an outdoor pool roof-tent cover for the season. Instead of folding a thin sheet that feels like it wants to wrinkle and leak, a thicker tarp gives you more workable structure. Once it’s tensioned with ties through the grommets, it’s easier to keep the cover more evenly laid, which helps water run off rather than pooling.

Another example: for firewood, you generally want coverage that resists sun and tearing while still staying in place. If the wind catches the edge of a lighter tarp, you’ll be fixing it constantly. A heavy-duty sheet is meant to reduce that hassle.

What to watch before you buy

Even with the “water-proof” positioning, tarps still depend heavily on setup. If you don’t create good drainage (slight slope, no big low spots) or if you don’t secure the edges well, water can collect or find its way where tension breaks.

Also, you should confirm fit expectations based on your actual space. The size is listed as 20x40 FT, which is large—great for bigger covers, but it can be awkward if you’re trying to cover a small area or if you need a more tailored shape. And because the input doesn’t specify the exact tarp weight beyond a brief “140 g” mention, you may want to double-check the product page details to ensure the material profile matches what you’re imagining.

Mini FAQ

Will this tarp work for a pool roof tent setup?

It’s specifically described as a plastic cover for an outdoor pool roof tent, so it’s clearly aimed at that kind of covering use case. Still, your results depend on your support frame and how you attach and tension it.

Does the tarp include grommets for tying down?

Yes, it’s described as having grommets, which is important for securing tarps in wind-prone areas.

Is it meant to stay outside under sun?

The listing positions it as UV resistant, which is the right direction for outdoor storage and seasonal covers. No tarp is indestructible, but UV resistance helps.

How good is it for covering firewood?

Firewood coverage is explicitly mentioned. If you secure it well and keep water from pooling, a heavy-duty waterproof tarp can help reduce exposure to rain.

Final verdict

Worth considering if you want a large, heavy-duty tarp with 12 mil thickness, grommets for fastening, and a design goal that focuses on outdoor weather resistance (waterproof positioning plus UV and tear resistance). It fits best when you’re covering bigger areas—like pool roof-tent style setups or protecting firewood—where thin sheets feel like they never stay put.

You may want to skip it if you’re covering a small space that needs a more tailored size, or if you expect “set it once and forget it” performance without good tensioning and drainage. In that case, any tarp can disappoint. The safe move is to verify the full details on the product page and compare the size to your actual coverage needs before you buy.
