A tarpaulin (US: // TAR-pəl-in, UK: // tar-PAW-lin), or tarp, is a large sheet of strong, flexible, water-resistant or waterproof material, often cloth such as canvas or polyester coated with polyurethane, or made of plastics such as polyethylene. In some places such as Australia, and in military slang, a tarp may be known as a hootch. Tarpaulins often have reinforced grommets at the corners and along the sides to form attachment points for rope, allowing them to be tied down or suspended.
Inexpensive modern tarpaulins are made from woven polyethylene; this material is so associated with tarpaulins that it has become colloquially known in some quarters as polytarp.
The word tarpaulin originated as a compound of the words tar and palling, referring to a tarred canvas pall used to cover objects on ships. Sailors often tarred their own overclothes in the same manner as the sheets or palls. By association, sailors became known as "jack tars".
In the mid-19th century, "paulin" was used for such a cloth; here General Rosecrans tells a subordinate how to improvise a boat:
"A boat has been ordered up, but to make sure a large paulin will be sent down to you, with which, spread under a lot of wagon-beds, you will be able to make a large scow." (War of the Rebellion: Official Records of the Union and Confederate Armies, series 1, volume 5, page 260, November 1861)
"Two wagon beds ... were placed upon frames ... Thus constructed, they were placed upon a duck paulin, which was drawn up tightly around the beds and secured." (Ibid., page 275)
Tarpaulins have multiple uses, including as shelter from the elements, i.e., wind, rain, or sunlight, a ground sheet. Tarpaulins are often used during the build process to protect brickwork and masonry from weather damage. Tarpaulins are also used for a fly in camping, a drop sheet for painting, for protecting the infield of a baseball field, and for protecting objects, such as unenclosed trucks, semi-trailers or freight cars as well as wood piles. Such was the demand for tarpaulins by the New South Wales Government Railways, up until 1990, they operated their own tarpaulin factory. It is also used on outdoor market stalls to provide some protection from the elements of nature. Tarpaulins are also used for advertisement printing, most notably for billboards.
Another historical use of a tarpaulin is to cover seats in a stadium that are rarely used, are in venues oversized for a venue, or are obstructed view seats in a multi-purpose stadium or indoor arena for a certain sport. The entire third deck of the Oakland–Alameda County Coliseum is also covered in tarp for Oakland Athletics games, but is uncovered for Oakland Raiders games, while portions of the upper deck CenturyLink Field in Seattle are covered with images of the Seattle Sounders FC crest or sponsor logos in games which do not require use of that seating.
Perforated tarpaulins are typically used for medium to large advertising, or for protection on scaffoldings, the aim of the perforations (from 20% to 70%) is to reduce wind vulnerability.
Polyethylene tarpaulins have also proven to be a popular source when an inexpensive, water resistant fabric is needed. Many amateur builders of plywood sailboats turn to polyethylene tarpaulins for making their sails, as it is inexpensive and easily worked. With the proper type of adhesive tape, it is possible to make a serviceable sail for a small boat with no sewing.
Tarpaulins can be classified based on a diversity of factors, such as material type (polyethylene, canvas, vinyl, etc.), thickness, which is generally measured in mils or generalized into categories (such as "regular duty", "heavy duty", "super heavy duty", etc.), and grommet strength (simple vs. reinforced), among others.
Tarpaulins can also be classified by size—a common determining factor for consumers in acquiring tarps—and measured in width by length. Actual tarp sizes are generally about three to five percent smaller than the advertised size. (Thus, a tarp advertised as 20 ft × 20 ft (6.1 m × 6.1 m) will actually measure about 19 ft × 19 ft (5.8 m × 5.8 m).) Some other factors that may influence a purchase decision include color (often they come in blue, green, black, or silver), grommet type (aluminum, stainless steel, etc.), and grommet-to-grommet distance (these often run between 18 in (460 mm) and 5 ft (1.5 m)). The weave count, a measure of tarp strength, often runs between (8 and 12 per square inch) and the greater the count, the greater its resistance against ripping in high wind conditions. Tarps may also be washable or non-washable and waterproof or non-waterproof, and mildewproof vs. non-mildewproof. Tarp flexibility refers to its ability to remain pliable during cold winter months; some tarps offer more flexibility than others in cold weather. Some manufacturers also advertise their tarps as "rot-proof", but this may be more a subjective than an objective measurement.
Type of material
A polyethylene tarpaulin ("polytarp") is not a traditional fabric, but rather, a laminate of woven and sheet material. The center is loosely woven from strips of polyethylene plastic, with sheets of the same material bonded to the surface. This creates a fabric-like material that resists stretching well in all directions and is waterproof. Sheets can be either of low density polyethylene (LDPE) or high density polyethylene (HDPE). When treated against ultraviolet light, these tarpaulins can last for years exposed to the elements, but non-UV treated material will quickly become brittle and lose strength and water resistance if exposed to sunlight.
Canvas tarpaulins are not 100% waterproof, though they are water resistant. Thus, while a little bit of water for a short period of time will not affect them, when there is standing water on canvas tarps, or when water cannot quickly drain away from canvas tarps, the standing water will drip through this type of tarp.
Polyvinyl chloride ("vinyl") tarpaulins are industrial-grade and intended for heavy-duty use. They are constructed of 10 oz/sq yd (340 g/m2) coated yellow vinyl. This makes it waterproof and have high abrasion resistance and tear strength. These resist oil, acid, grease and mildew. The vinyl tarp is ideal for agriculture, construction, industrial and trucks.
U.S. Color Scheme
For years manufacturers have used a color code to indicate the grade of tarpaulins, but not all manufacturers follow this traditional method of grading. Following this color-coded system, blue indicates a lightweight tarp, and typically has a weave count of 8×8 and a thickness of 0.005–0.006 in (0.13–0.15 mm). Silver is a heavy-duty tarp and typically has a weave count of 14×14 and a thickness of 0.011–0.012 in (0.28–0.30 mm).
Some of the more common colors in that scheme are:
Color Name Approx. thickness Blue light-duty tarp 0.005–0.006 in (0.13–0.15 mm) Yellow/Orange medium-duty tarp 0.007–0.008 in (0.18–0.20 mm) Green medium-duty tarp 0.009–0.010 in (0.23–0.25 mm) Silver heavy-duty tarp 0.011–0.012 in (0.28–0.30 mm) Brown super-heavy-duty tarp 0.016 in (0.41 mm)

Tarps have been used both within works of art, and also to conceal works of art from public view.
A 2017 work called Tarp by Amy Malbeuf consists of a blue tarp with the word "tarp" written on it in glass beads. The work was created in reference to the use of tarps in improvised shelters by people who are homeless in Oakland, California.
Native American artist Nicholas Galanin's 2018 retrospective art show Dear Listener at the Heard Museum included tarps as both elements of sculpture and as part of the gallery presentation. The sculpture Creation with Her Children, a collaboration between Galanin and Merritt Johnson, depicts Creation clothed in a gown made from a blue plastic tarp. While Creation carves her own face, her children, depicted as animals who have human hands, are gathered near her feet. According to the gallery text and the printed program, the tarp, which is "used heavily in indigenous communities," references "contemporary Indigenous life and the long standing effects of forced relocation under colonial rule."
In one of the galleries housing Dear Listener, the skylights have been covered with blue tarps. The decision to do so was made by a museum curator in reference to the use of tarps in Indigenous North America as an inexpensive and widely available material used for building and repair. It also casts a blue glow on the room, and creates "a reminder that we live in a borrowed landscape, under artificial light and in air-conditioned spaces."
Tarps have also been used to conceal art from public view, including statues of Confederate generals Robert E. Lee and Stonewall Jackson, an illegally placed bust of Edward Snowden, a fiberglass casting couch in a Hollywood mall that took on new meaning after sexual abuse allegations against Harvey Weinstein in 2017, and a sculpture of the founder of Halifax, Nova Scotia.

Creation with Her Children: In this work Galanin collaborated with artist Merritt Johnson. The two depict a female figure, Creation. Creation is shown carving her own face out of necessity. Her ensemble, a 17th-century style European gown, consists of a variety of materials — most notably a blue plastic tarp. The blue tarp — used heavily in Indigenous communities, creating protection from the elements, and even employed to build tipis known as tarpees — references contemporary Indigenous life and the long standing effects of forced relocation under colonial rule. Her children, two animals with human hands peeking out from under her skirt, do not emerge. They expose their sharp teeth — an act of self-defense from the world they would encounter should they leave the protection of their mother ... Blue Tarp Skylight: The decision to place blue plastic tarps over the skylights in the Dennis Lyon Family Crossroads Gallery was deliberate choice made by Erin Joyce, the Museum's Fine Arts Curator. No, the roof is not leaking or in need of repair, however the tarps do serve a critical function in the exhibition space. Firstly, they work to illuminate the use of blue plastic tarps in Indigenous North America as a cost-effective and readily available tool used to repair roofs, build tipis and various other applications. Secondly, it casts a luminous blue glow down into the gallery — which creates an atmospheric feeling of coolness, playing off the presence of a polar bear placed in the center of the room — but it is all artificial. It serves to create a reminder that we live in a borrowed landscape, under artificial light and in air-conditioned spaces.

Some works more or less iterate the Museum’s core concept of radical denial. Alberta-based Métis artist Amy Malbeuf’s Tarp (2017), for instance, represents the fantasy the Museum asks us to assume. The work is a big blue tarpaulin on the wall, with the word tarp inscribed on it with glass beads. The wall text describes the piece in a voice from the future. It defines what a tarp 'was' in 2017, and then provides context: “In cities like Oakland, where capitalist development drove people out of homes, tarps became an important part of the improvised shelters which often appeared at the margins of urban areas.” While there is no doubt in my mind that Malbeuf made the piece in sympathy for and in solidarity with the staggering homeless population in Oakland, the fantasy risks increasing the conceptual distance between museumgoers and the displaced by making the reality of this crisis contrafactually pluperfect.

The artist and curator asked Heard Museum to drape the skylights in blue plastic tarps, not just for mood but also to pay tribute to the many uses of this inexpensive resource in Native communities. These tarps are often used to patch leaky roofs, cover damaged car windows and as temporary shelters and sheds. The blue plastic tarps are so ubiquitous, there’s even a nickname for homes made out of them – 'tarp-ees.' The blue tarps appear 'because they are readily accessible and very inexpensive. A lot of people are living below the poverty line on reservations,' Joyce explains ... 'Creation With Her Children,' is a collaboration with Galanin’s partner, artist Merritt Johnson. A blue plastic tarp peeks out as a layer of the woman’s petticoat. Her children are animals who gather at her feet, beneath the folds of her gown. In one hand she holds a mirror, and in the other she holds a knife, gazing at her reflection while carving her own face 'out of necessity.'
