How to glue fiberglass parts together

Updated April 17, 2017

Attaching fibreglass pieces together may be necessary if you are working on a building or craft project. Use an epoxy adhesive glue specifically designed to attach fibreglass pieces to one another. These glues can easily be found at most building-supply stores. You must follow a few steps to clean, smooth and prepare the fibreglass for gluing, and this process is easy even for fibreglass novices. By doing this work yourself, you will save the cost of hiring someone else to professionally complete the project.

Smooth the surface area of the fibreglass parts using sandpaper before gluing the pieces together. This will help the adhesive stick to the parts better.

Wipe an acetone liquid over the fibreglass parts with a rag. This clean and removes dust and dirt, which is an important step to ensure the fibreglass adheres to the glue.

Purchase an epoxy glue specifically designed for use on fibreglass from a building-supply store. The label on the glue should say it is used for fibreglass. If you're not sure, ask a store employee.

Spread a layer of epoxy glue on the surface area of the fibreglass part where you want it to attach to the other fibreglass piece. Press the surface with the glue on it against the surface of the other fibreglass part.

Hold the two pieces together for about 30 seconds, then gently lay the fibreglass on a sheet of newspaper outside until fully dry.


Wear gloves and an apron to protect your hands and clothes from the acetone and epoxy glue.


If fumes from the acetone or epoxy glue become too intense, open a door or window.
