Cracks or chips in a fiberglass boat hull can be very expensive to have professionally repaired. Depending on the damage to the boat, and the owners personal fortitude, a do-it-yourselfer can produce professional results without the professional price.
The filler product being used is key to a successful repair. It is important to select a filler that is extremely strong and fast-working. The filler must be flexible. It must not absorb moisture, and it must not shrink. For the do-it-yourselfer, it is best to also choose a filler that does not clog the sandpaper and one that does not require additional polyester coatings.
Once the proper filler has been selected, the next steps are proper preparation and application. Although each filler brand will have specific preparation/application procedures, this article covers the general aspects thereof.
The area to be repaired must be clean, dry and rough. If a crack is being repaired, make a V incision over the area to be repaired. This incision provides some depth and volume in which the filler can properly bond. Follow the brand-specific directions for mixing the filler being used. Apply the filler generously in layers over the area being repaired.
When the area has been properly filled, wait the recommended length of time for the filler to properly set up. Sand the area smooth and you should have a nice repair. The repaired area is now ready for painting. Please make sure you understand the requirements for painting over the filler you choose. Some fillers require special additional polyester fillers or putty to be applied over the filler. Other fillers are ready to prime and paint without additional product applications.
Fiberglass boat repairs can be very easy to do, and can save the do-it-yourselfer a lot of moneygive it a try. |
