Tarpaulins, or tarps, are sheets of strong, flexible, water-resistant or waterproof material. They are often made of cloth such as canvas, vinyl, or polyester coated with polyurethane, but can also be made of plastics such as polyethylene. A polyethylene tarpaulin (polytarp) is not a traditional fabric but a laminate of woven and sheet material. It is created by weaving polyethylene plastic strips into a fabric that is tear-resistant and stretch-resistant. This fabric is then coated with a layer of low-density polyethylene (LDPE) to create a protective shiny finish. While plastic tarps are not considered a traditional fabric, they have fabric-like properties and are used in a similar way to fabric tarps.

What You'll Learn
Tarps are made from a variety of materials
Polyethylene: This is one of the most popular materials for tarps due to its versatility and affordability. Polyethylene tarps, often referred to as "poly tarps" or "polytarps", are made from woven strips of polyethylene plastic with sheets of the same material bonded to the surface. They are known for their water resistance, durability, and flexibility. Polyethylene tarps are widely used in construction, agriculture, and debris covering, among other applications.
Canvas: Canvas is a traditional tarp material that has been used for centuries. It is typically made from cotton or hemp and is known for its durability and water resistance. However, canvas tarps are not 100% waterproof, and prolonged exposure to standing water will cause leakage. Canvas tarps are commonly used in outdoor applications such as covering objects on ships or in campgrounds.
Polyester: Polyester tarps are another commonly used option. Polyester is a variation of the polyethylene family and is often woven or used as a thread. Polyester tarps are often coated with polyurethane to enhance their water resistance. They are strong and flexible, making them suitable for various applications, including tents and awnings.
Nylon: Nylon tarps, also known as rip-stop tarps, are made from woven fabric that is resilient to ripping and tearing. They are lightweight and breathable, making them ideal for providing shade while still allowing air circulation. Nylon tarps are often used in fencing, party tents, and for covering items that don't need protection from heavy rain.
Polypropylene: Polypropylene tarps offer a lightweight alternative to canvas. They are known for their water resistance, durability, and longevity. Polypropylene tarps are significantly lighter than canvas, making them easier to handle and transport.
Vinyl: Polyvinyl chloride (PVC) or vinyl tarps are heavy-duty and industrial-grade. They are constructed from coated vinyl, which makes them waterproof, highly resistant to abrasion, and capable of resisting oil, acid, grease, and mildew. Vinyl tarps are commonly used in agriculture, construction, and truck coverings.
These are just a few examples of the diverse materials used for tarps. Each material has its own strengths and weaknesses, making certain tarps more suitable for specific applications than others.

Polyethylene tarps are a popular choice
One of the standout features of polyethylene tarps is their exceptional waterproof capabilities. The material naturally repels water, making these tarps ideal for protecting items from rain or snow. Whether you need to cover construction sites, safeguard outdoor belongings like boats, cars, and furniture, or create temporary shelters during emergencies, polyethylene tarps provide reliable protection against the elements.
The affordability of polyethylene tarps is another factor contributing to their popularity. Compared to other tarp materials, they offer a cost-effective solution without compromising on quality. This makes them a preferred choice for individuals and businesses seeking a balance between budget and performance. The wide range of colours and sizes available in polyethylene tarps also enhances their versatility, ensuring there is a suitable option for various needs.
Polyethylene tarps are commonly referred to as "poly tarps" and have become so prevalent that they account for a significant 56% share of overall tarp sales within the global tarp industry. Their popularity is a testament to their effectiveness in providing protection, durability, and versatility at a reasonable cost. Whether for personal or commercial use, polyethylene tarps offer a dependable solution for numerous applications.

Canvas tarps are also common
Tarpaulins, or "tarps", are sheets of strong, flexible, water-resistant or waterproof material. They are often made of cloth, such as canvas, or polyester coated with polyurethane, or plastic, such as polyethylene.
Canvas tarps are used by truckers, painters, and farmers worldwide. They are also used to cover outdoor equipment and belongings, protecting them from rain, sunlight, dirt, and other harsh environmental effects. Canvas tarps are also treated to be water-repellent, although they are not 100% waterproof. They are also available in a variety of colours and sizes.
Canvas tarps are not recommended for covering indoor items as the dyes used to treat them can stain surfaces, and they have a strong odour. They are also not suitable for covering roofs as they can only hold a certain amount of water before leaking.

Vinyl tarps are heavy-duty
Tarpaulins, or tarps, are sheets of strong, flexible, water-resistant or waterproof material. They are often made of cloth, such as canvas, or polyester coated with polyurethane, but they can also be made of plastics such as polyethylene.
Vinyl tarps, derived from the ethylene molecule, are typically more heavy-duty than polyethylene tarps. They are constructed of coated vinyl, which makes them waterproof and highly resistant to abrasion and tears. They are also resistant to oil, acid, grease and mildew. Vinyl tarps are ideal for heavy-duty, long-term applications and are commonly used in agriculture, construction, transportation, and for covering outdoor equipment, furniture, vehicles, and boats.
The lifespan of a vinyl tarp can vary depending on how often it is used and how well it is cared for. With proper care, a high-quality vinyl tarp can last for several years. Vinyl tarps are also easy to maintain, as their smooth surface makes them easy to wipe down and keep in good condition.
Vinyl tarps are available in a variety of thicknesses, ranging from 14 mils to 22 mils or 10 oz to 40 oz per sq yard. The thicker the tarp, the more durable it will be. They also come in a range of colours, including clear vinyl and solid colours.
Vinyl tarps are more expensive than polyethylene tarps, but they last longer and are more resilient. They are also more durable than poly tarps, which are made from woven polyethylene.

Tarps are used for a range of applications
One of the primary uses of tarps is to provide protection from the elements, including wind, rain, and sunlight. They are often used to cover and protect objects such as machinery, boats, generators, furniture, and camping equipment. Tarps are also used to protect outdoor structures like patios, roofs, and athletic fields. For example, baseball tarps are used to keep the grass field cool and dry during rain, while gym floor covers use thick poly-coated tarps to protect the polyurethane floor.
Tarps are also commonly used in the transportation industry, particularly for covering and securing loads on flatbed trucks. Specific types of truck tarps include smoke tarps, which protect loads from exhaust damage, and steel tarps, which are designed to safely haul stacked steel. Lumber tarps, made from heavy-duty vinyl, are another type of truck tarp used to cover and protect lumber during transport.
In agriculture, tarps are used to cover bales of hay, with hay tarps being specifically designed to be UV-treated, waterproof, and strong enough to withstand heavy rains and winds. Vinyl tarps are also used in agriculture to protect crops and equipment, as they are waterproof, tear-resistant, and resistant to mildew and rot.
Tarps are also useful for outdoor activities such as camping and sports. Campers may use tarps as a lightweight, waterproof shelter, while sports teams might use them for privacy screens or to provide shade during practice. Additionally, tarps can be used to create temporary structures like tipis, also known as "tarpees," which are used by some indigenous North American communities.
The versatility of tarps lies in the variety of materials they can be made from, including canvas, polyester, nylon, polypropylene, and polyethylene. Each material has unique properties that make it suitable for specific applications. For instance, polyethylene tarps are known for their excellent tear and puncture resistance, while canvas tarps are breathable and versatile.
