Canvas has many useful applications in the outdoors. As a heavy-duty fabric, it can be used as tent material or a covering for boats and other equipment. The weave of the material swells when wet, repelling water without any chemical treatment. However, waterproofing is highly recommended, due to the likelihood that canvass will mold after a short period of time. Petroleum and fluoropolymer-based products are popular synthetic options for this task, but they have been shown to cause environmental and respiratory health problems. Linseed oil provides a safe and healthy alternative when waterproofing canvas, and can be applied in a few easy steps.
