Canvas tarps are an alternative to polyethylene, or poly, tarps. The material is single fill 100% cotton military duck and treated with paraffin for water and mildew. A canvas tarp often has a longer lifespan than many plastic tarps and, in addition to not being made of plastic, the amount of usage also makes it more environmentally friendly than a poly tarp. Although the fabric is treated, if a canvas tarp is retreated with such chemicals as Kanvak, the material will continue to last and be water repellent. In terms of protecting materials, a canvas tarp allows for more breathability than plastic, will not accumulate water or condensation on the inside, and traps less heat. Typically, a canvas tarp is best suited as a ground cover or project cover for wood piles, farm equipment, or painting. We carry canvas tarps in olive green and khaki colors.

Canvas tarps, however, can shrink when the weather changes and are not recommended for use as an outdoor canopy or for a truck tarp. If pulled too tight, a canvas tarp can also rip in the wind if used during transport. Although a truck tarp may be water resistant, it is not waterproof, and if water accumulates on it, the water will eventually seep through the material. Also, when the tarp is wet, the color and coating may rub off onto the covered materials. In addition, a canvas tarp will protect the covered materials from mildew, mold, and rot, but mildew and mold can form on the outside of the fabric when near moisture.

Weight of Canvas Tarps are 17 oz. after water resistance and chemical treatment.
