Instructions

    • 1

      Sand down the area around the rupture until it is as smooth as possible. Tears in fiberglass or composite hulls are often rough and jagged. Your patch will hold better when the affected area is smoothed out in preparation.

    • 2

      Clean the area thoroughly with cleaning solution and allow to dry. It is essential that the area be free of dust and debris.

    • 3

      Lay the first fiberglass patch over the damaged area and apply the epoxy resin. The resin gives the fiberglass its rigidity once it dries, as well as providing protection of its own against abrasion.

    • 4

      Add a few more layers of fiberglass and resin over the affected area. How many layers you want to use is a matter of personal choice, but consider using more in high-wear areas such as the nose and tail or along the center line of the boat.

      Sand down any drips or imperfections once the epoxy resin has cured fully. The curing process can take as long as 24 to 48 hours depending on your chosen resin type.
