If you’re a DIY enthusiast, you know finding adhesives for fiberglass and plastic is tough. If you’re not, the fact may come as a surprise to you.
Plastic and fiberglass, on the other hand, are two materials that are quite distinct. Fiberglass is usually a type of reinforced plastic with glass fiber added to the mix. Later we’ll delve into it in further depth.
Even though that is the case, both materials have smooth surfaces with none of the adhesives sticking.
However, finding the finest adhesive for fiberglass and composite materials is now a difficult task. Continue reading to understand why you should use sealants specifically formulated for the substance.
What is Fiberglass
Fiberglass is a famous word that has come to be so well-known that people typically only think of one thing when they hear it: Fiberglass is fluffy pink insulation that lines the attic of your house, right? That’s only half the story, in reality. While Owens Corning Inc. held a trademark on the well-known insulating product known as Fiberglass, fiberglassing itself has a well-known core structure and several uses.
Fiberglass is a laminate made primarily of glass-like material. Glass is heated until molten and forced through tiny channels to produce fiberglass before being drawn through tiny holes. Microfiber is derived from the small glass filaments, which are produced by this method because they are so thin—in fact, they’re measured in microns—as a result of which they’re known as microfiber.
The fibers can be woven together to form larger cloth pieces, or they may be kept in a more disorganized state for the familiar puffy texture, which is used as soundproofing and insulation. The sort of glass fiber utilized is determined by the amount and quality of the extruded fibers. It’s necessary for certain applications that glass fibers be free of foreign materials; however, this necessitates additional processing.

How to bond fiberglass, aka GRP or glass reinforced plastic
This is a composite material with exceptional structural strength, making it popular for demanding or stressed applications.
Fiberglass is a lightweight material, and there’s a high demand for adhesives to secure it because it can’t be welded and mechanical fasteners not only contribute to component weight, rattling, and vibration loosening, but they may also harm the material’s structural integrity if it must be drilled.
Fiberglass Uses
- Bath tubs
- Hot tubes
- Marine
- Construction
- Tools
After scrubbing, put the piece back in a container of alcohol for 24 hours overnight. Use Permabond Cleaner A or isopropanol (not methanol or white spirits) to clean it.
Use one of the following techniques to lightly abrade them:
- A wet-and-dry sandpaper (carborundum paper) of 320 grade is suggested.
- Red Scotch Brite pad
To remove any contaminants or loose particles, degrease the grill once again.
It is acceptable to bond as received, but if you want a consistent bonding surface and improved mechanical keying of the adhesive, it’s recommended that you perform this surface preparation.
What is the best adhesive to bond fiberglass?
Adhesives come in a variety of forms and have varying levels of promise. The best adhesive for each carbon fiber application will be determined by understanding the cure process as well as what the bond will need to survive.
Cyanoacrylate
- Superglue, epoxy, crazy glue, ca glue are examples of bonding adhesives. Consider using a black, hardened grade such as 735 low viscosity or 737 medium viscosity for carbon fiber reinforced polymer bonds. Permabond 731 is an excellent choice for clear bonds.
Two component epoxies
- Permabond two-part epoxies cure at room temperature and have exceptional bond to fiberglass.
Structural acrylics
- TA4246 is a high-end MMA grade with excellent carbon fiber bonding capabilities.
Polyurethane adhesives
- All Permabond polyurethane adhesives are strong, have high peel strengths, and offer excellent impact resistance.
With so many carbon fiber bonding solutions to choose from, the desired cure method, environmental protection, and required temperature tolerance are all crucial factors in selecting the appropriate adhesive.
How to Glue to Fiberglass Step-by-Step Guide
There are a plethora of adhesives that will join fiberglass, but when cost, effectiveness, and efficiency are considered, “Plastic Fusion” by the Super Glue Corporation is a smart choice. It’s an acrylic-based epoxy composed of resin and hardener that’s especially good at bonding fiberglass to other plastic-like materials.
Things You Will Need
- Rubber gloves
- Aluminum foil
- 2 pieces of fiberglass
- 2 clean clothes
- Super Glue Plastic Fusion
If the epoxy does get on your skin, wash it with an industrial hand cleanser like Zep Reach. If at all feasible, using a spatula or spoon, carefully peel the bonded region off of your skin until it is gone. Epoxy that has gotten into your eyes should be rinsed under running water and, if necessary, seen by a doctor.
Step 1
Find a clean and well-ventilated place to work, because breathing the epoxy is not safe. The area should be at least 68 degrees Fahrenheit when the epoxy is ready, and it should be kept away from any open flames (epoxy is combustible).
Step 2
To prevent coming into contact with the epoxy, put on rubber gloves and apron.
Step 3
Lay a large piece of aluminum foil on the work surface to prevent the epoxy from adhering (at least larger than your piece of fiberglass) while working.
Step 4
Make sure the fiberglass is resting on some aluminum foil.
Step 5
Wipe the surface of the fiberglass you wish to glue with a clean cloth, making sure no dirt or grime is on the fiberglass. Rub a dry towel over the fiberglass until any moisture on it evaporates. Allow for a few minutes for the fiberglass to dry naturally. Repeat this step with the second piece of fiberglass.
Step 6
Remove the epoxy with a Super Glue syringe and mix the solution for around one minute.
Step 7
Apply the required quantity of epoxy to the first fiberglass piece. The ratio is one dab of epoxy for each square inch of fiberglass you want to cover. If you’re closer to the edge of the fiberglass and need more epoxy, be sure it’s about an inch from the edge so it doesn’t squirt out when you press the other fiberglass piece onto it. Repeat these steps for the second fiberglass piece.
Step 8
Push the two fiberglass pieces firmly together. Depending on how you want the fiberglass sheets to be positioned, you may or may not need to hold them in position until the epoxy has cured (five to 10 minutes). If one piece is directly adhered to another, you may not need to hold them in place.
Step 9
Allow 24 hours for the epoxy to fully cure before removing the mold.
