Autumn is a great time to spend time outdoors, but the rain and damp weather can make things a little tricky. Wet leaves, sudden showers, and moisture can leave your patio, furniture, tools, and other outdoor items soaked. A tarpaulin cover is a simple way to keep them protected without putting up a permanent structure.
The best part is that you don’t always need complicated equipment to create one. With a few basic supplies and the right setup, you can make a temporary rain cover that works for patios, decks, outdoor seating areas, storage spaces, and more. The key is to create enough slope for water to run off instead of collecting on the tarpaulin.
Why Use a Tarpaulin During Autumn?
Autumn rain doesn’t always give much warning. A sunny morning can turn wet by afternoon, and everything may stay damp long after the rain is gone. That lingering moisture can leave cushions and furniture stained, make things smell musty, and cause rust on metal items.
A tarpaulin gives you a simple layer of protection between your belongings and the weather. It can be especially useful when you don’t want to move everything indoors or install a permanent cover.
You can set up a custom tarpaulin to cover the top while leaving the sides open. This gives you some cover from the rain without making the whole area feel closed in.
Materials Needed
Before getting started, gather everything you need. Having the materials ready will make setup much easier.
- Heavy-duty waterproof tarpaulin
Go for a sturdy tarpaulin that’s big enough to cover the area properly. Make sure it’s waterproof too, since a thin sheet may not hold up well against regular rain, wind, and outdoor use.
A heavy-duty tarpaulin with reinforced edges and sturdy grommets is a good choice for a DIY outdoor cover. Make sure the tarpaulin extends far enough beyond the area so rain does not simply run onto the items underneath.
- Bungee cords or nylon paracord
You’ll need something to secure the tarpaulin. Bungee cords are convenient because they provide some flexibility when the tarpaulin moves with the wind. Nylon paracord is another useful option and can be tied securely around poles, posts, or other anchor points.
Use enough tie-down points to keep the tarpaulin steady rather than relying on just two corners.
- Support lumber or a central pole
A central pole or support lumber can help create a higher point in the middle of the tarpaulin. This is especially useful for creating a peaked setup.
The raised centre gives rainwater somewhere to run instead of allowing it to collect in a flat pocket. If you are using lumber, make sure it is stable and properly supported.
- Tent stakes or heavy weights
You’ll also need something to anchor the tarpaulin at ground level. Tent stakes can work well when the ground allows you to secure them firmly.
If you’re setting up the tarpaulin on concrete or a paved patio, bricks, rocks, or tie-down hooks can work well. Just make sure they’re secure enough to stop the tarpaulin from shifting.
DIY Tarpaulin Cover Ideas for Autumn Rain
There are several ways to set up a tarpaulin depending on the shape of your space and what you want to protect.
1. Basic Sloped Tarpaulin Cover
This is one of the easiest setups for a patio or small outdoor seating area. Attach one side of the tarpaulin to a higher point, such as a wall, post, or sturdy support, and lower the opposite side.
The slope allows rainwater to move toward one side instead of sitting in the middle. Keep the lower edge away from furniture and walking areas so water does not drain directly onto the things you are trying to protect.
2. Centre-Peak Tarpaulin Shelter
Covering a bigger area? A pole under the centre of the tarpaulin can create a raised peak. Stretch the sides out and secure each end.
This setup gives rain a few easy ways to run off instead of collecting in one spot. It also leaves more space underneath, so it works well for larger seating areas or outdoor storage.
3. Patio Furniture Cover
If your main goal is protecting outdoor chairs, tables, or other furniture, a tarpaulin can be placed over the setup and secured at several points.
Don’t place the tarpaulin directly over cushions or fabric. A little space underneath can help prevent moisture from getting trapped and gives water somewhere to run off.
4. Outdoor Storage Cover
Tarpaulins can also be useful for protecting firewood, gardening tools, boxes, bins, and other outdoor supplies.
For storage, let the tarpaulin hang a little past the top and sides of whatever you’re covering. Don’t wrap it too tightly, though—a bit of airflow can help keep moisture from getting trapped underneath.
Step-by-Step Preparation
Once you have the materials, setting up your tarpaulin cover is fairly straightforward.
Step 1: Choose the Area
Start by checking the space and the things in it. Knowing what you want to cover makes it easier to work out the right tarpaulin size.
Clear away anything that could interfere with the setup. Also check for nearby branches, sharp edges, or loose objects that could damage the tarpaulin.
Step 2: Check the Weather and Wind Direction
Before you put the tarpaulin up, check the wind and rain direction. If it’s an exposed spot, don’t be afraid to use extra tie-downs. Position the tarpaulin so the sloped side directs water away from the area you are covering.
Step 3: Position the Central Support
If you are using a central pole or support lumber, place it where you want the highest point of the tarpaulin to be.
The support needs to be stable. If the pole moves, the tarpaulin can shift with it. For a temporary setup, make sure the base is secure and won’t easily tip over.
Step 4: Lay Out the Tarpaulin
Place the tarpaulin over the support and spread it evenly. Check that the material covers the entire area with some extra room around the edges.
Try to avoid having the tarpaulin stretched completely flat. A slight slope or peak is important because it gives rainwater somewhere to go.
Step 5: Attach the Bungee Cords or Paracord
Use the tarpaulin’s reinforced grommets to secure it. Attach bungee cords or nylon paracord to the corners and other appropriate points along the edges.
Do not rely only on the four corners if the tarpaulin is large. Adding a few extra tie-down points can make the setup more stable.
Step 6: Secure the Edges
Use tent stakes when working on soil or grass. Push them into the ground at a suitable angle, so they hold the tie-down lines securely.
On concrete or paved surfaces, use heavy bricks, rocks, or sturdy tie-down hooks to keep the tarpaulin in place. Put them where they won’t get in the way.
Step 7: Check the Slope
Give the tarpaulin a quick once-over from each side. Make sure the surface is sloped enough that water won’t pool anywhere.
This is one of the most important parts of the setup. A heavy pool of rainwater can put extra pressure on the tarpaulin, support, and tie-down points.
Step 8: Test the Setup
Give the tarpaulin and supports a gentle check by hand. Look for loose cords, shifting anchors, or areas where the tarpaulin is sagging.
It can also help to spray a small amount of water over the tarpaulin with a hose, when practical, to see how it drains. The water should move toward the lower edges rather than sitting on top.
How to Keep Dampness Under Control
A waterproof tarpaulin helps keep rain out, but it does not automatically prevent every type of moisture problem. If the tarpaulin is completely closed around the edges, moisture can sometimes become trapped underneath.
For outdoor furniture, leave a little space for air to move around. Don’t cover wet cushions, fabrics, or other damp items too tightly, as the moisture can get trapped underneath.
It is also a good idea to check the covered area after heavy rain. Remove standing water and give damp surfaces a chance to dry when conditions improve.
Common Mistakes to Avoid
- One mistake is choosing a tarpaulin that’s too small for space. If it only just covers the area, rain can easily get underneath and leave things wet.
- Another issue is putting the tarpaulin up completely flat. Without a slope or a raised centre, rainwater can pool in the middle and put extra weight on the tarpaulin.
- Using too few anchors is another issue, particularly in windy weather. The more exposed the tarpaulin is, the more important proper tie-downs become.
- Finally, don’t ignore the condition of the tarpaulin. Check for small tears, damaged grommets, or worn edges before putting it up. A weak point can become a bigger problem once the tarpaulin is under tension.
When Should You Take the Tarpaulin Down?
A DIY tarpaulin cover is great for temporary protection. But if strong winds or a storm is expected, take it down so the tarpaulin and support don’t get damaged.
Before packing the tarpaulin away, make sure it’s completely dry. A little leftover moisture can turn into a musty smell or mildew while it sits in storage. Store the tarpaulin somewhere dry and clean, so it is ready for the next time you need it.
Conclusion
A tarpaulin can be a pretty simple way to keep your outdoor space dry during autumn rain. With a heavy-duty waterproof tarpaulin, some bungee cords or nylon paracord, a centre support, and a few solid anchors, you can cover patios, furniture, storage areas, and other outdoor spaces without much fuss.
The main thing to remember is proper drainage. Give the tarpaulin a slight slope or raise the middle to create a peak, then secure all the edges properly. Check it now and then, especially after rain or strong winds. A little prep can help keep your outdoor space usable and your things protected from autumn moisture.
