Can Fiberglass Showers Be Repaired? A Step-by-Step Guide

Yes, fiberglass showers can be repaired! While the damage may look severe, the repair process is relatively straightforward for minor cracks, chips, or indentations. By using a basic epoxy repair kit and a few essential tools, you can restore your fiberglass shower to its former glory in just one day.
Preparing for the Repair
Before you begin, make sure your shower is indeed made of fiberglass. Tap the surface with your knuckle or a wooden spoon. If it has a soft, hollow, non-metallic sound and feels slightly flexible, it’s likely fiberglass.
Next, gather the necessary materials:

Fiberglass repair kit (containing polyester resin, hardener, fiberglass mesh, colorants, sandpaper, and thickener)
Protective gear (gloves, respirator mask, and eye protection)
Cleaning solvent (such as acetone)
Mixing container and stirring tool
Sandpaper (80-grit to 400-grit)

Repairing Minor Cracks and Chips

Clean the damaged area by cutting any jagged or protruding glass fibers and lightly sanding with medium-grit sandpaper to remove contaminants. Rinse with acetone to ensure proper adhesion.

Mix the polyester resin according to the kit instructions, adding the hardener and colorant to match your shower’s color. Test the color on a small area before proceeding.

Apply the resin mixture to the damaged area using a rubber spreader, ensuring it fills the crack or chip evenly.

Allow the resin to cure for 2-3 hours or longer for larger repairs, as specified by the kit instructions.

Sand the repaired area with progressively finer grits of sandpaper until it’s flush with the original surface.

Apply a finishing polish to help the new area blend seamlessly with the rest of the shower.

When to Call a Professional
For extensive damage, such as large cracks or holes that extend several inches, it’s best to call a professional. They can assess the underlying cause and provide a more comprehensive repair solution.
Additionally, if you’re unsure about the extent of the damage or the repair process, it’s always better to err on the side of caution and seek the help of a qualified professional.
By following these steps and using the right materials, you can effectively repair minor fiberglass shower damage and save yourself the cost of a full replacement. Remember to prioritize safety by wearing protective gear and ensuring proper ventilation during the repair process.
