Frequently Asked Questions (FAQs)
1. What type of tarp is most waterproof?
Heavy duty PVC (vinyl) tarps are generally the most waterproof option. While canvas tarps and polypropylene (or 'poly' tarps) are often water resistant, they may not be fully waterproof in all cases.
2. What is the best material for a waterproof tarp?
Tarps made mostly of polyethylene are considered the best material for a waterproof tarp. They are durable, strong, and have excellent waterproof abilities compared to other materials like canvas. Nylon ground covers and polyethylene mesh tarps are also lightweight and breathable while still offering some waterproof features.
3. Is a tarp 100% waterproof?
Not all tarps are 100% waterproof. While tarps are generally made with water-resistant features, it's important to determine if the tarp you have or are considering buying is truly waterproof or just water-resistant. Different tarps serve different purposes, so it's crucial to choose the right one for your specific needs.
4. What is the difference between a poly tarp and a tarp?
Poly tarps are often used for lighter operations or temporary use, while vinyl tarps are more durable and resistant. Vinyl tarps are better suited for heavy rain, snow, strong winds, insects, pests, and flying debris. However, vinyl tarps are generally more expensive compared to poly tarps, which are more cost-effective for smaller, light-duty operations.
5. How thick does a tarp have to be to be waterproof?
To be fully waterproof, tarps are typically made with a thickness of 14 mil, 16 mil, or 18 mil. These heavy-duty tarps are made of polyethylene (PE) material and provide 100% waterproof protection. Camo and Clear Tarps are also made of PE material and offer the same level of waterproofing.
6. Which is better polypropylene or polyethylene tarps?
Polypropylene tarps are more resistant to chemicals and organic solvents compared to polyethylene tarps. This makes them a better choice for manufacturing facilities. However, polypropylene is less flexible than polyethylene, so consider your need for stretchable fabric before deciding between the two.
