My Buying Guides on 18 Foot Round Tarp
When I first started looking for an 18 foot round tarp, I realized there are quite a few factors to consider to get the best one for my needs. Here’s what I learned through my experience that might help you pick the right tarp too.
Why Choose an 18 Foot Round Tarp?
For me, the 18 foot size struck the perfect balance between coverage and portability. It’s large enough to cover my equipment, create a shelter, or protect a picnic area, yet still manageable to handle and store. If you need something bigger or smaller, make sure to consider your specific use cases.
Material Matters
One of the first things I looked at was the tarp material. Most 18 foot round tarps come in polyethylene, canvas, or vinyl. I found polyethylene tarps to be lightweight and waterproof, which is great for general outdoor use. Canvas tarps are heavier but much more durable and breathable, ideal if I need something for long-term coverage. Vinyl tarps are super tough and weather-resistant but tend to be pricier. Think about how often and where you’ll use your tarp to choose the right material.
Waterproof and Weather Resistance
Since I needed my tarp for outdoor activities, waterproofing was crucial. Check if the tarp is rated for water resistance or waterproofing. Some tarps have special coatings or reinforced edges that improve durability and prevent leaks. Also, UV resistance is important if you’ll leave it exposed to sunlight for long periods.
Grommets and Reinforcement
I always check the grommets because they make it easier to secure the tarp. The best 18 foot round tarps have rust-resistant metal grommets spaced evenly around the edges. Reinforced corners and hems add strength and prevent tearing, especially when you’re tying the tarp down tightly.
Weight and Portability
Depending on how often I need to move the tarp, weight is a key factor. The 18 foot round size can get bulky, so I look for a tarp that balances durability with being lightweight. Some tarps come with a storage bag or straps, which makes transportation and storage easier.
Price and Warranty
I set a budget before shopping and compared prices across different brands. Sometimes paying a bit more upfront means better quality and longer lifespan. Also, check if the tarp comes with a warranty—this shows the manufacturer’s confidence in their product and can save you money if something goes wrong.
Additional Features
Some tarps come with handy extras like reinforced loops, reflective edges for visibility, or UV protection. Depending on your needs, these small features can make a big difference in performance and safety.
My Final Tips
- Measure your space carefully to confirm 18 feet is the right diameter.
- Read customer reviews to get real-world feedback on durability and usability.
- Consider how you’ll be securing the tarp and whether you need extra accessories like bungee cords or tie-down ropes.
- Store your tarp properly when not in use to extend its life.
By keeping these points in mind, I was able to find an 18 foot round tarp that fits my needs perfectly. I hope my guide helps you make an informed choice too!
