How to Repair Cracks in Fiberglass Boats

Boating is a great sport. Nothing is better than a warm day spent on a beautiful body of water. It’s so relaxing and the view can relieve stress. It’s very popular and people who love boats more than likely own one that is constructed from fiberglass. Fiberglass is very lightweight and is known to be cost efficient and very sturdy. Fiberglass can get damaged along the way. It can crack and even get shattered over the course of time. If your boat has a crack in the fiberglass, it is probably a very sinking feeling.  But don’t worry too much. If the damage is small it can be fixed rather easily. You can correct these damages with a little bit of time and energy. It is not a complicated process to complete at all. It’s relatively quick and easy to repair minor dings and cracks in your fiberglass boat. Doing this project yourself can, of course, save you some substantial money depending on the severity of the actual damage. However, if you do not feel comfortable making the repairs yourself, please feel free to call and ask for professional grade assistance to correct your boat damage. Here is how you can repair the damage and cracking of your fiberglass boat. Read on for more information below.


Necessary Items:

  • Gel Enamel (marine type)
  • Sandpaper (120 grit)

  • Fiberglass Cloth
  • Epoxy Resin
  • Resin Applicator
  • Paint Brushes

Step 1

Whenever you are dealing with harsh chemicals and things like fiberglass you all safety precautions. Wear protective goggles, rubber gloves and a respirator or mask to protect against inhalation.

Step 2

Look for cracks in the back. Fill all of them with resin and allow it to dry. You will need to work quickly as it hardens when exposed to direct air.

Step 3

Use a paint brush to apply a layer of resin over the cracks. Then, apply a layer of fiberglass cloth. The resin will serve as an adhesive and keep the cloth in the right place.

Step 4

Give the work area about 4-6 hours to completely dry. Now, use some wet 120 grit sandpaper to smooth out the area so that it is flush with all the other area surrounding it. Do not rush through this part. If you sand the area too quickly, you may damage the patch work.

Step 5

Apply some gel email on the end of a paint brush. Apply to the affected area. This enamel will give the finish a high gloss shine and it is tough enough to withstand the elements of the water and the everyday wear and tear of boating.
