Waterproofing

Waterproof or water-resistant describes objects relatively unaffected by water or resisting the ingress of water under specified conditions. Such items may be used in wet environments or under water to specified depths. Waterproofing describes making an object waterproof or water-resistant. “Water resistant” and “waterproof” often refer to penetration of liquid water. Permeation of water vapor is reported as a water vapor transmission rate.
