Trust extra-large tarps from Canopies and Tarps to handle truly big jobs.
To ensure you're getting the best coverage, a tarp needs to come from a common piece of material that has no seams across the middle. A tarp should be an uninterrupted piece of fabric to ensure that water, dirt, wind and more can't get in.
Unfortunately, a bunch of smaller tarps can't replace a large tarp. It doesn't matter how cleverly they are overlapped or how well they are stitched together, a Franken-tarp will fail quickly-and you'll find yourself frustrated and angry that the items stored beneath are ruined. Don't put yourself through that aggravation. Invest in a large tarp from the get-go; it'll save you time and money in the long run.
When it comes to finding big tarps that can get the job done, large poly tarps are your best option. A large tarp gives you all the surface area you need for that big job and guarantees it will help keep the elements at bay to keep your stuff safe from UV rays, moisture, dirt, debris and anything else nature throws its way.
