Canvak Buying Guide

Canvak Canvas Preservative is not a waterproofing product. Instead, Canvak is a water resistant material. Canvak is made up of mineral spirits and petroleum waxes. The product was developed during WWII to preserve the coating on the Olive Drab duck tents. Then during the Viet Nam era it was reestablished for the government ounce duck tents.

The mineral spirits is the carrier which dissipates from the coated material that has been treated and leaves the wax behind, kind of like waxing a car, the wax left on material treated will cause water to bead and run off.

Canvak Canvas Preservative needs to be used prior to the degrading of coating that is already applied on a cotton canvas product. If a canvas is already leaking, that means the coating on canvas is already damaged. Canvak will not prevent the damaged canvas from leaking.
