Fiberglass is an excellent material for bathroom tubs. Many homeowners prefer it because of its style and durability. However, fiberglass tubs can also acquire damage over time, and more often than not these damages come in the form of holes. While the job of repairing fiberglass tubs may seem intimidating at first, it can actually be done even without the help of a professional. The materials you will need for the project include a fiberglass fabric, a fiberglass epoxy resin mix, fine grit sandpaper, oxygen bleach, mild detergent, acetone stripper, tongue depressor, and some popsicle sticks. The guide below will help you with the repair step by step:


Step 1. The first step to repairing holes in a fiberglass tub is to evaluate how large the damage is. In large fiberglass holes, fiberglass cloth is often used. However, if you’re dealing with a small or narrow hole, you can simply use epoxy resin.

Step 2. Using a stripping agent, strip the part where the hole exists and sand the area surrounding it using 100-grit sandpaper. Allow the area to dry and remove sanding residue using a brush or a cloth.

Step 3. After stripping and sanding the damaged area, it’s time to apply the fiberglass epoxy resin. Following the instructions in the label, mix the epoxy resin and fill the hole with it using a popsicle stick. See to it that you push the epoxy inside to fill holes completely. After applying the epoxy, wipe the excess with a rug or cloth. Allow the epoxy to dry and sand the area using 200-grit sandpaper.

Step 4. In case you’re dealing with a wide hole, you will have to patch it up. Take the fiberglass fabric and cut it according to how wide the hole in the tub is. Next, apply epoxy resin into the hole but make sure to leave a space for the fiberglass fabric to come in. Insert the fabric next and apply epoxy resin on top of it until the hole is completely covered. Again, get rid of excess epoxy resin by wiping it off with a rug or cloth. Ally the mixture to dry and sand the surface using 200-grit sandpaper. Cut any fabric that may be protruding and cover the hole again with epoxy. Allow to dry and sand the area.

Step 5. Bathroom tubs are usually white in color. If this is the case with your tub, then there’s no need for you to paint the hole to match the color with the tub. Otherwise, you will have to repaint the area you have just repaired to make sure the color of the fixed portion is uniform with the color of the rest of the tub. To get rid of any soap residue, apply wax to the tub before painting it. Once you are done repainting the tub, your tub will be as good as new.
