21oz Treated Canvas Tarps

Tarp Supply’s Heavy Duty 21oz Canvas Tarp is the strongest canvas tarp that we offer. This canvas tarp is silicon treated and water and mildew resistant. It is stronger and thus heavier than the 16oz and 18oz canvas tarps. We carry colors olive drab (dark green), green, mustard tan, and brown. Treated canvas is designed for outdoor use as the treatment gives off an odor and may leave stains.
