Need a tough tarp that can handle just about anything? This 13x13 foot canvas tarp is built like a tank. It's 35 mil thick (that's 0.86mm), made from tightly woven polyester canvas that's been treated to be waterproof, UV resistant, and windproof. The seams are triple-stitched for extra strength, and it has rust-proof aluminum grommets every 40 inches (and at each corner), so you can tie it down securely with rope (some might be included). Use it to cover your firewood pile, protect outdoor furniture, as a temporary roof patch, a ground cloth for camping, a cover for your boat or pool, or on construction sites. It's stiff when new but softens up, and it folds flat for storage. The color options are green, black, or white. Just be aware: manual measuring means size might vary by an inch or two, and screen colors can differ slightly. To clean it, just rinse with water and let it air dry. Whether you're a homeowner, camper, or contractor, having a reliable heavy-duty tarp like this in your shed or garage is always a smart move. It's way better than those flimsy blue tarps that rip in a season.
