WLRHGl Sun Shade Sail 3 x 18.5 m Review: a massive waterproof tarp that does the job if you can handle it

I’ve been using this WLRHGl “sun shade sail” for a few weeks now, and the first thing to understand is: this is basically a huge heavy-duty tarp, not one of those light fabric sails you see over hipster patios. The size I tried is 3 x 18.5 m, so 55.5 m². It’s long, it’s heavy, and you really need to know what you’re going to do with it before hitting “buy”.

I set it up along my backyard to create a covered area over a parking spot and part of a work zone near a shed. So I didn’t use it as a free-floating sail above a terrace, more like a long waterproof roof between the house and some poles. In that context, it makes sense: it’s clearly made more for protection than for style. If you expect something light and airy, you’re going to be surprised by the weight.

The product page mixes the words “shade sail” and “tarpaulin”, and honestly in real life it behaves much more like a tarp. It’s thick PVC, 422 g/m², and you feel it the second you try to lift the roll. I had to get a second person to help unroll it properly and avoid it dragging in the mud. If you’re alone and not very strong, that’s something to think about.

Overall first impression: very solid, very heavy, not very pretty. It’s clearly aimed at people who want to protect cars, tools, wood, or create a waterproof cover, more than those looking for a stylish patio sail. If you’re in the second category, you might want something else. If you just want a big waterproof cover that holds up, then it starts to look interesting.

On the price side, it’s obviously more expensive than the thin PE tarps you find in discount stores, but that’s normal given the size and thickness. For around this price range (varies with size), you’re paying for a lot of material and a more serious build. If you compare it to professional-grade PVC tarps or custom-made covers, it actually comes out as decent value. You’re getting 55.5 m² of thick, waterproof cover with metal eyelets already in place.

The question is more: do you really need this level of tarp? If your goal is just to have a bit of shade over a small patio table, honestly, this is overkill. It’s heavy, not very nice-looking, and a pain to install for such a simple use. In that case, a lighter HDPE shade sail or a smaller canvas would be more practical and probably cheaper. On the other hand, if you need to protect a car, machinery, wood piles, or create a semi-permanent covered area for work or storage, the cost starts to make sense because you’re likely to keep it longer.

Another detail: the included rope is a bit on the light side for such a big tarp. It’s usable, but if you add the price of stronger ropes, bungee cords, or wall anchors, the “real” budget goes up a bit. So keep that in mind when comparing options. The tarp itself is good value on the material side, but the whole installation can end up costing more than you first think if you need to build a full support structure.

Overall, I’d say value is good for people who actually need a heavy-duty waterproof cover and have a clear use for this long size. For casual garden shading or decorative use, it’s not the smartest way to spend your money. It does the job, but it’s like using a sledgehammer to drive a small nail: it works, but it’s not the most sensible tool for that job.

Let’s be honest: from a design point of view, this thing is purely functional. The colour is grey, fairly neutral, so it doesn’t scream “cheap blue tarp”, which is already a plus. But visually it still looks like industrial PVC. If you stretch it over a terrace, it will give a bit of a carport or temporary hangar vibe, not a stylish outdoor lounge. For my use (covering a work area and a car), that’s fine. For a pool or a designer deck, it might feel a bit off.

The shape is a long rectangle, 3 m by 18.5 m. That’s a slightly odd format if you’re thinking in terms of standard patio dimensions. It’s more suited to cover a driveway, a long row of wood, a boat, or the side of a building. I ended up folding one end back on itself because my area was shorter than 18.5 m. It works, but you end up with a double layer and a big fold, which is not very pretty and can catch wind if you don’t tie it down properly.

On the positive side, the layout of the eyelets every 50 cm is practical. It gives you a lot of fixing points, so you can distribute the tension and avoid concentrating stress on a few spots. When wind picks up, that makes a difference. I used bungee cords on some eyelets to give the whole setup a bit of flexibility. The tarp stays in place, and the load on the eyelets feels reasonable. No deformation or tearing so far.

One thing I noticed: because the tarp is quite thick (10 mm listed, but in reality that refers more to the overall packed thickness; the sheet itself feels in the 0.4–0.5 mm range), it folds with big, stiff creases. Those creases take time to relax. After a few days in tension in the sun, they started to fade, but don’t expect a perfectly flat, smooth look from day one. Again, this confirms the general feeling: this is a practical cover, not a decorative sail. If you accept that, the design is coherent. If you want something visually neat and light, this is not the best choice.

The main material is PVC (polyvinyl chloride), and you can feel it. It’s heavy, a bit stiff when cold, and clearly thicker than the usual cheap tarps you find in supermarkets. The listing mentions 422 g/m², which is in the higher range for general-purpose tarps. In hand, it feels close to what you’d use for truck side covers or serious construction site protection, not the flimsy stuff that tears after the first storm.

They insist that it’s made from virgin, non-recycled PVC. I obviously can’t verify that myself, but the texture is quite consistent, and there are no weird thin spots or colour variations on my unit. The coating is uniform, and the fabric inside (the reinforcement grid) is well embedded. I tried pulling hard near an eyelet and also bending it sharply to see if the surface cracked or turned white. Nothing obvious. It just leaves a crease but no sign of delamination.

The eyelets are metal (look like aluminium or nickel-plated steel). They’re pressed firmly into reinforced hems. I checked a few with a screwdriver to see if they’d start to loosen – they didn’t. For my use, I tensioned the tarp over a span of about 3 m wide, with ropes going to wall hooks and metal poles. After a few days of wind and rain, the eyelets and seams still look fine. No tearing, no stretched holes. The hemming around the edges is double-stitched and heat-welded, which gives a good impression of durability.

On the downside, PVC has its quirks: it’s not breathable at all, and it can get quite hot when exposed to full sun. Under the tarp, you get shade and you stay dry, but the trapped air can feel stuffy if there’s no airflow on the sides. Also, if you’re sensitive to smells, there is a bit of that typical plastic/solvent smell when you first unpack it. It faded after a few days outside, but the first 24–48 hours are noticeable. For an outdoor tarp, it’s not a big issue, but I wouldn’t use it indoors in a closed room.

I obviously haven’t had it for years, but based on a few weeks of outdoor use and the build quality, it feels built to last more than the usual bargain tarps. I’ve had cheap ones that start to fray and lose eyelets after a single season. Here, the fabric and seams look more like something that could handle multiple seasons of sun and rain without falling apart immediately.

The PVC doesn’t show any early signs of cracking or drying, even after staying stretched in the sun for several days. The grey colour is also a good choice for ageing: it doesn’t show dirt as much as white and doesn’t fade as fast as bright colours. I dragged one edge over rough concrete by mistake while installing it; it left a scuff mark, but no hole. That’s the kind of abuse that kills thin PE tarps quickly. Here, it just looks a bit scratched.

The eyelets and hems are really the key points for durability, and they’re done properly. Double-layered edges, reinforced corners, and plenty of fixing points spread the tension. I deliberately over-tightened a couple of points to see if the fabric would start to pull or deform; it didn’t. For long-term use, what will probably limit its life is more UV exposure over years rather than mechanical failure, but that’s the same for almost all plastics.

The flip side of this durability is the weight and handling. At over 20 kg, this is not something you take up and down every weekend. Folding it alone is a pain, and moving it around when wet is even worse. So I see it more as a semi-permanent installation: you set it up for the season (or for a long project) and then leave it. If you want a light shade you can easily install and remove, this is not it. But if you’re tired of replacing shredded cheap tarps every year, this one makes more sense in the long run.

In use, the tarp does what it says: it blocks water completely and handles bad weather pretty well. I had two solid rain episodes since I installed it, one of them with gusty wind. The area under the tarp stayed dry, and I didn’t see any water seeping through the material. The only places where water can be a problem are the low points if you don’t tension it enough: puddles form, and then the weight can pull down the whole thing. That’s not specific to this tarp, it’s just physics, but with a tarp this heavy, a big water pocket can really drag the structure down if you’re sloppy with the slope.

For UV protection, it’s hard to measure without equipment, but in practice, it cuts the sunlight very strongly. Underneath, it’s almost full shade, more like being under a plastic roof than under a fabric sail. I left some wooden planks and cardboard boxes under it, and they stayed dry and didn’t bleach in the sun. So for storing stuff outdoors or protecting a car, it does the job. Compared to my older green PE tarp, this one feels thicker and less prone to flapping and shredding in the wind.

Wind resistance is decent, but it depends 90% on how you fix it. The eyelets and material hold up, but because the surface is huge (55 m²), it acts like a big sail if the wind catches it from the side. In my case, I fixed three sides to solid structures (wall, fence, heavy posts) and left only one side partially open. In strong wind, you can hear the tarp move and see it flex, but nothing ripped so far. I’d be careful using this fully free-standing over a large area with just a few poles – you really need a solid frame or multiple anchor points.

In practice, I’d say the performance is very solid for typical tarp tasks: covering materials, creating a temporary carport, or protecting a worksite. As a stylish shade sail for chilling by the pool, it’s less convincing because of the weight, look, and lack of airflow. It works technically, but the feeling under it is more like being under a plastic roof than under a light canvas. So it’s efficient, but not particularly pleasant if you’re thinking “cosy terrace”.

When the package arrived, I honestly thought they’d sent the wrong item because of the weight. The box is not very big (around 36 x 29 cm according to the specs), but it’s dense: about 21 kg for this size. Inside, you get the folded tarp, a polyethylene rope, and a small instruction leaflet. Nothing fancy, just the basics. The rope is okay for light tensioning, but if you plan to use this in windy conditions, I’d strongly recommend getting stronger ropes or ratchet straps.

The tarp itself is already fitted with metal eyelets every 50 cm or so all around the edges. That’s a strong point: you don’t need to punch extra holes or do DIY reinforcement from day one. The eyelets looked cleanly crimped on my unit, no sharp edges or loose metal bits. I checked each corner and the reinforcement seems decent: extra material, thicker seams. It feels like it’s meant to be pulled tight quite hard without tearing immediately.

One thing that’s a bit confusing: the listing talks about “shade sail” for patio, deck, pool, etc., but the technical sheet screams multi-purpose tarp. And in hand, it’s clearly more of a tarp: thick PVC, slightly shiny, and not very breathable. If you stretch it over a patio, you’ll get shade and full waterproofing, but also a bit of a “warehouse” look. For a garden or construction use, that’s fine. For a cozy lounge area, it’s more questionable.

In practice, I used it to cover a car and some building materials along a wall. I fixed it with the included rope at first, then replaced part of the setup with stronger cords and bungee cords. The tarp doesn’t come with poles or mounting hardware, so you really need to have your own structure or anchor points ready: walls, posts, trees, or a metal frame. If you expect a ready-to-go “sail kit”, this isn’t it. It’s more a big blank protective sheet that you adapt to your situation.
