How to Waterproof a Boat Cover
Boat covers made from synthetic fibers are treated with a waterproof finish. While these covers may last longer than natural fiber canvas, like canvas boat covers, they have to be re-waterproofed about every five years. They also require treatment after a very thorough scrubbing. Fortunately, they don't require scrubbing except in extreme circumstances and, fortunately, boat cover waterproofing kits are available through most marine supply houses and boat supply stores.

1
Clean the boat cover according to the manufacturer's cleaning recommendations. If you apply the waterproofing treatment to a dirty cover, you won't be applying the waterproofing treatment to the boat cover but to the dirt on the boat cover.
-
2
Allow the boat cover to air dry in an open, well-ventilated area. A well-ventilated area will allow the cover to dry more quickly and, once the cover is dry, you won't have to move the cover to treat it.

3
Spray a thin, even coat of the waterproofing product onto the boat cover. Allow the waterproofing product to dry completely, then spray a second coat onto the boat cover. After the second coat dries completely, the cover may be put on the boat or stored.
