The hull is very important to boats because it keeps them afloat. If it is in bad shape, these water vehicles just cannot be as efficient, safe and high performing. Even though they are made from reliable materials like fiberglass, cracks, holes and damages may soon develop on them after some time. By learning how to repair a fiberglass hull on boats, they can easily solve these inconveniences even without spending too much in exchange for professional help.
For people who are very much eager to learn how to repair a fiberglass hull on boats, they need to gather all the important materials and tools for the job. Among them are sandpaper, scissors and a fiberglass repair kit. Furthermore, do not forget to bring a de-waxing solvent, a dust mask and safety glasses. Moreover, this task can be easier with the availability of other things including resin roller, Formica and paste wax. Other things to bring are polyvinyl alcohol, disk grinder and rags.
Doing this particular project is not that hard. Identify parts that need repair. Work on these damaged parts one at a time. Start with one part. After deciding where to start, remove the damage by cutting it out of the hull. From the damage, cut your way up to 12 inches from its center. For instance, cut out a 17-inch diameter hole for a damaged part that extends to 5 inches.
Do the work from the inner part to make the task easier. Buy a de-waxing solvent and then use it to take out the wax from the part that is under repair. Be sure to de-wax the inner part as well as the outer part of the hole. Get the disk grinder then use it to make the edges smooth. If this tool does not get the job done, use sandpaper instead as support in enhancing the texture of the edges.
The next step is to put a coat of paste wax right into the damaged area. When doing so, spare the edges of the hole. Get a big piece of Formica, preferably one that is larger than the hole itself. Right onto the Formica, apply some polyvinyl alcohol. Use it as a backer by taping it right at the outside of the hull, particularly at the center of the damage.
It is now time to use the fiberglass repair kit. This includes a resin, a gel coat, a fiberglass fabric and a catalyst. Get a piece of fabric and cut it the same size similar to that of the Formica. For this one, several layers can do the job right. Likewise, add the resin and the catalyst. Spray or paint about 20 millimeters thick of gel coat on the backing right from the outside.
Use polyester resin to moisten the mat and fabric. Simply put the three initial layers of fabric and mat into the gel coat. Get the resin roller and use it to smooth the bubbles out. Follow them up with another four layers. After putting on the final layer, use the resin roller on it. This will produce a finished look. Seal it with polyvinyl alcohol. After this, you can now take the Formica backing off. Cover the imperfections with gel coat and then let it dry for some time.
