Fiberglass Repair 101…


Fiberglass repair would not be needed unless this was the ideal material for use in boat construction! What is commonly known as “fiberglass” is actually a combination of a resin and a glass or composite fiber. The resin is normally a two-part epoxy mixture or a two-part polyester mix. Each has its strengths and weaknesses. The fiber or cloth is encapsulated in the resin layer, giving it extra strength. Depending on the type of work to be completed, the fiber can be applied from spools (as in pipe construction), hand laid in cloth mats, or applied with a chop-gun. Use of a chop-gun and hand-layed are the two most common methods in marine construction. Fiberglass repair is almost entirely accomplished by the hand-laid method.

For non-structural repairs and where filling or fairing are needed, additives are often added to the resins before they cure to adjust the consistency or other working characteristics of the resin.
