To use, simply clean the surface you want to protect and then apply the cork spray with a paintbrush or roller.

For best results, apply two coats and allow each coat to dry completely before applying the next. Once dry, your home will be better protected from the elements and you’ll have peace of mind knowing that you’ve done something good for the environment!

Is Cork Spray Waterproof?

Cork spray has water-repellent and breathable properties. Most manufacturers claim cork spray is waterproof. However, it is always a good idea to test the spray on a small area of the item you wish to waterproof before applying it to the entire surface.

To test the spray, apply a small amount to a corkboard. Then, place the board in a sink or bucket of water. Allow it to sit for a few minutes, then check to see if the water has seeped through.

This will help you to determine if the spray is truly effective and if it will cause any damage to the item.
