What Are The Different Types Of Fiberglass Repairs?

Fiberglass Repairs

One of the more versatile materials out there, fiberglass has been used for a variety of applications, ranging from boats to pipes to storage tanks. As with any material, fiberglass is susceptible to damage, meaning repairs must be made. Here, we discuss the various types of fiberglass repairs, so that you can best address whatever problem you’re facing with this material.


Grinding is the most basic type of fiberglass repair. This involves the removal of a damaged section of the material by grinding or sanding it away. It is important to be methodical when grinding, as any areas left unground can lead to further damage or compromise the structural integrity of the material.

Fiberglass Reinforced Plastic (FRP) Repairs:

Fiberglass Reinforced Plastic (FRP) repairs involve the replacement of the damaged material with a new section of fiberglass-reinforced plastic.

This process is similar to the way a patch is used on a tire. The repair material must be molded to the exact specifications of the original material so that the two pieces fit together perfectly. It is important that the repair material is of the same type and quality as the original material, in order to retain the strength and durability of the original material. This type of repair is often used to repair holes and gouges in boats, vehicles, and other materials.

Vinylester Resin Repairs:

Vinylester resin is a type of resin that is used to repair larger sections of fiberglass. This type of repair can be used to repair cracks, gaps, and larger sections of damage. This method involves prepping the area, filling the damaged area with a vinylester, then filling the area with chopped fibers and resin.

Chopped Fiberglass Repair:

Chopped fiberglass repair is a method of repairing smaller sections of fiberglass damage, often used on small areas where grinding and FRP repairs are not feasible. This method involves the application of a gelcoat to the area, followed by layers of chopped fiberglass strands and resin. This method is often used to repair small sections on fiberglass piping, tanks and other fiberglass products.

These are all some of the common methods of fiberglass repair. It is important to take the necessary time to repair any damage to your fiberglass, as failing to do so can lead to further damage, or even compromise the structural integrity of the material. If you’re looking to do a fiberglass repair but are not sure which method to use, it is always a good idea to consult a professional for help.
