Grey 20oz Heavy Duty Thick Waterproof Canvas Fabric 600D Outdoor Cover 1x Metre

Good colour and durability. Using it as a waterproof table mat, works great

Great item, worked really well for replacing the seat on one of our garden chairs. Has held up well so far this summer.

I’ve used the A-Express 20oz heavy-duty waterproof canvas for several outdoor projects over the past year, and overall, I’ve come to rely on it as a staple for weatherproof tasks. It’s extremely tough, genuinely waterproof, and can withstand rain, cold, wind, and even snow without breaking down. That said, there’s a very important aspect that users need to be aware of before buying—especially if you’re thinking of using it indoors or in semi-enclosed spaces: the VOCs and smell. Straight out of the packaging, the chemical smell is very strong. It’s that harsh, plasticky, almost rubbery scent that clings to your hands after handling it for even a few seconds. This comes from the waterproof coating, which is most likely polyurethane or a similar treatment applied to the dense 600D polyester base. If you bring this fabric into a room without much ventilation, the smell will quickly fill the air. It can cause a scratchy throat, nausea, or even dizziness in more sensitive individuals. I had initially considered using this for a window cover in a camper conversion but had to abandon that idea almost immediately. Even leaving a 1x1.5 metre piece inside a garage left the entire space with a lingering odour after an hour. It’s not dangerous per se, but for anyone sensitive to VOCs or who values clean indoor air, I would not recommend it for internal use unless it has been thoroughly aired for several weeks. To treat the smell, I found a combination of methods helpful. Leaving it out in the sun for multiple days helped speed up the off-gassing process significantly. Sunlight and airflow really do the heavy lifting here. I also washed a piece in a mix of water, bicarbonate of soda, and white vinegar, which reduced the surface residue slightly, though it may compromise the waterproof layer if done too aggressively. After a couple of months of outdoor exposure, including rain and heat, the odour was mostly gone and the fabric became much more tolerable to handle and store—even in semi-enclosed areas like sheds. When used as intended—outside—this fabric is phenomenal. I’ve used it to create a durable tarp for covering firewood, which remained intact and didn’t leak a drop during weeks of rain. I made a bench cover for an outdoor seating area that is still holding strong and hasn’t faded significantly despite constant sun exposure. One of the most practical uses has been as a makeshift canopy during BBQs and garden gatherings. It stretches well without tearing, dries quickly, and sheds water like a duck’s back. I’ve also used it to make a padded tool roll, a heavy-duty backpack base, and even as reinforcement fabric for a wheelbarrow liner. Each time, I was impressed by how thick yet flexible it remained under stress and how easy it was to stitch with a good needle and strong thread. The olive green colour is stylish and blends in well with natural settings like gardens, campsites, or forested areas. I used a metre of it to patch an old pergola roof and another section to line the inside of a dog shelter I built last autumn. It's survived everything from frozen sleet to scorching sunshine, with no cracking or warping. The water beads off cleanly, and even when soaked through in heavy storms, it doesn’t stay damp long. After using it for over a year, I can confidently say it lives up to the “heavy-duty” claim in every way. Despite all these positives, my advice remains the same: do not use this fabric indoors unless it’s been treated or aired for an extended period. Even when cut down to smaller pieces, the coating continues to emit VOCs and chemical smells for quite a while. Over time, especially with sun and rain exposure, the odour does fade and becomes negligible. But right out of the packaging, it’s far too intense for any confined space or enclosed application. In conclusion, this is a brilliant material for anyone doing outdoor projects—from garden covers and camping setups to DIY tarps and weatherproofing fixes. It’s strong, reliable, waterproof, and holds up brilliantly under stress. Just don’t expect to bring it inside straight away. With the right prep and outdoor use, it’s an incredibly useful and affordable tool in your materials arsenal.

This is Brilliant stuff it Blocks all sunlight & Uv rays. I've just bought my third lot that's how good it is. Excellent Value for money & Next day delivery.Plus you can easily cut it to the size you want. I would highly recommend

This is the second time I have purchased this strong fabric in navy. First to make blinds for my micro camper and when this vehicle went to the scrap yard I bought more of the fabric and made outdoor cushion covers. Very impressed with the strength and quality of the fabric. Awaiting more velco to finish off the 4th cushion cover.

Good quality and easy to work with. I made seat cushion covers and buyer is delighted with the good all round quality of the fabric.

Just about everything with this material is very good. It’s easy to cut, machines well, folds well, pins well, but….. I used it to repair outdoor boat covers and it looked great - until the sun came out! I now have light blue patches on an otherwise dark blue canopy. Very disappointed that no reference was made to its light fastness.

Great fabric and very waterproof, when it has rained it dries quickly. Recovered all my outdoor cushions with it.

Item was received per the items description, and it’s orange! Seems like it will function as I anticipated.

This seems great, but time will tell. It sews very easily and is also easy to cut if you have a good table to spread it out on. I've only made one large bag with it but ordered more to make a grill cover. After cutting, it did not fray like some other materials I've worked with. It seems strong..I ordered more so I guess I like it.

The material was dyed brown and rubs off on my clothes. It is not color fast abd may be a toxic dye. I never took it out of box until last week. I would like to return the material even though I missed the return deadline. Been busy with my family member who has cancer. PLEASE SEND ME A LABEL YOU CAN CHECK THE MATERIAL AND THE DYE COMING OFF OF THE MATERIAL. I HAVE BEEN A LONG TIME CUSTOMER AND ALWAYS RETURN MY ITEMS. BUT THIS TIME I WAS EXTREMELY BUSY AND WAS UNABLE TO RETURN AT DEADLINE.🤭

Although I was able to sew this fabric with a domestic machine, this fabric is thicker than what I thought it would be. The thickness caused a lot of bulkiness in the seams. I would purchase this item again, however, I would definitely use it for different projects, especially items that need waterproof materials.

Good quality fabric. Recovering my front porch chairs.
