Identifying the Problem
Fiberglass bathtubs are popular because they are lightweight, easy to install, and affordable. However, they are prone to cracking due to their flexible nature. If you notice a crack in your fiberglass bathtub, it is important to identify the problem and fix it as soon as possible to prevent it from getting worse.
Types of Cracks
There are different types of cracks that can occur in a fiberglass bathtub. The most common types of cracks are stress cracks and hairline cracks. Stress cracks are caused by the weight of the water and the person using the bathtub. Hairline cracks are small cracks that are barely visible but can grow over time.
Causes of Cracks
There are several reasons why a fiberglass bathtub may develop cracks. One common cause is improper installation. If the bathtub is not properly supported, it can flex and crack over time. Another cause of cracks is impact damage. If something heavy is dropped on the bathtub, it can cause a crack. Finally, age and wear and tear can cause cracks to develop over time.
How to Identify a Crack
To identify a crack in your fiberglass bathtub, you should look for the following signs:
- Discoloration or staining around the crack
- A visible crack on the surface of the bathtub
- A hollow or soft spot around the crack
- Water leaking from the crack
If you notice any of these signs, you should inspect the bathtub for cracks. You can do this by running your hand over the surface of the bathtub to feel for any irregularities or using a flashlight to look for any visible cracks.
In conclusion, identifying the problem with your fiberglass bathtub is the first step to repairing it. By understanding the types of cracks, causes of cracks, and how to identify a crack, you can take the necessary steps to fix the problem and prevent it from getting worse.
Materials Required for Repair
Repairing a fiberglass bathtub crack requires specific materials to ensure a successful repair. Here are the essential materials you will need:

-
Sandpaper: You will need fine-grit sandpaper or emery cloth to sand the surface of the bathtub before applying the repair material.
-
Putty knife and putty: A putty knife is necessary for applying the putty to the crack. Putty is used to fill in the crack and provide a smooth surface for the resin to adhere to.
-
Resin and hardener: The resin and hardener work together to create a strong bond between the fiberglass cloth and the bathtub surface.
-
Fiberglass cloth or mesh: Fiberglass cloth or mesh is used to reinforce the repair and provide additional strength to the bathtub.
-
Protective gloves and respirator: It is essential to wear protective gloves and a respirator when working with fiberglass repair materials to prevent skin and lung irritation.
-
Colorants and tinting products: If you want to match the color of your bathtub, you can use colorants or tinting products to blend the repair material with the surrounding surface.
-
Utility knife, scissors, and cardboard: A utility knife and scissors are used to cut the fiberglass cloth or mesh to the appropriate size. Using a piece of cardboard as a template can ensure a proper fit.
-
Rag and acetone: A rag and acetone are used to clean the surface of the bathtub before applying the repair material.
By having all the necessary materials on hand, you can repair your fiberglass bathtub crack quickly and efficiently.
Preparation for Repair
Before attempting to repair a fiberglass bathtub crack, it is important to properly prepare the surface to ensure the repair will be effective and long-lasting. The following steps will guide you through the preparation process:
Cleaning
First, clean the area around the crack with a household cleaner and a sponge. Make sure to remove any dirt, grime, or soap scum that may be present. This will help the repair material adhere properly to the surface.
Grit
Next, use a fine-grit sandpaper to roughen up the surface around the crack. This will help the repair material bond better to the surface. Be careful not to sand too aggressively, as this can cause further damage to the fiberglass.
Abrasive Cleaners
Avoid using abrasive cleaners on the surface, as they can scratch and damage the fiberglass. Instead, use a mild, non-abrasive cleaner to clean the surface.
Protective Gear
It is also important to wear protective gear when working with fiberglass repair materials. This includes gloves, a respirator mask, and safety glasses. Fiberglass repair materials can be harmful if they come into contact with your skin or are inhaled, so it is important to take proper precautions.
By following these preparation steps, you will be well on your way to successfully repairing a fiberglass bathtub crack.
Step-by-Step Repair Process
Repairing a fiberglass bathtub crack is a simple process that you can do yourself. Here is a step-by-step guide to help you get started:
-
Prepare the surface: Clean the cracked area with a mild detergent and warm water. Rinse it thoroughly and let it dry completely. Sand the area with fine-grit sandpaper to roughen the surface and remove any glossy finish. Wipe it clean with a cloth.
-
Mix the repair material: In a mixing tray, mix the fiberglass filler and polyester resin according to the manufacturer’s instructions. Add a thickener if necessary to adjust the working time. Stir the mixture thoroughly with a mixing stick until it is well blended.
-
Apply the repair material: Using a paintbrush, apply the repair material to the cracked area. Make sure to cover the entire area and fill the crack completely. Smooth out any bumps or lumps with a steel scraper or putty knife.
-
Apply the fiberglass cloth: Cut a suitable piece of fiberglass cloth to cover the repaired area. Apply the cloth over the wet repair material and press it down firmly. Make sure to remove any air bubbles or wrinkles. Apply more resin and fiberglass cloth as needed to build up the thickness.
-
Let it cure: Let the repair material cure for at least 24 hours or according to the manufacturer’s instructions. Keep the area dry and avoid using the bathtub or shower pan during this time.
-
Sand and buff: After the repair material has cured, sand the repaired area with fine-grit sandpaper to smooth out any rough spots or edges. Use a buffing compound to restore the glossy finish.
-
Apply sealer or paint: If necessary, apply a sealer or paint to match the color of the bathtub or shower pan. Follow the manufacturer’s instructions and let it dry completely before using the bathtub or shower pan.
Remember that fiberglass tubs and showers can develop cracks due to normal aging, wear and tear, or accidental damage. Surface repair can be done with a fiberglass repair kit, but internal repair may require professional help. Don’t ignore even small cracks or scratches, as they can lead to bigger problems over time.
Post-Repair Procedures
After completing the fiberglass bathtub crack repair, there are some post-repair procedures that you should follow to ensure that the repair is successful and long-lasting.
Firstly, it is important to wait for the repair to dry completely before using the bathtub. This usually takes around 24-48 hours, but you should check the instructions of the repair kit you used for specific drying times.
Once the repair is dry, you can use a buffing compound to smooth out any rough edges or bumps left over from the repair. This will also help to restore the glossy finish of the bathtub. Be sure to follow the instructions of the buffing compound carefully, and use a soft cloth or buffer to avoid damaging the repair.
After buffing, you may want to apply a sealer to the repaired area to provide extra protection against water damage and to help maintain the glossy finish. Again, check the instructions of the sealer you use and apply it carefully to avoid any damage to the repair.
It is important to note that even with proper post-repair procedures, the repaired area may not match the rest of the bathtub perfectly. However, following these steps can help to ensure that the repair is successful and long-lasting.
When to Call a Professional
While repairing a fiberglass bathtub crack may seem like a simple task, there are times when it is best to call a professional. Here are a few situations where it may be best to leave the job to the experts:
Extensive Damage
If the damage to your fiberglass tub is extensive, it may be best to call a professional. A professional will have the experience and tools necessary to repair the damage quickly and efficiently. Attempting to repair extensive damage yourself may result in further damage or a subpar repair.
Lack of Experience
If you have never repaired a fiberglass tub before, it may be best to call a professional. Fiberglass tub repair requires a certain level of skill and knowledge. A professional will have the experience necessary to repair the damage correctly and ensure that the repair lasts.
Cost
While repairing a fiberglass tub yourself may seem like a cost-effective solution, it can end up costing you more in the long run. If you make a mistake during the repair process, you may end up causing further damage that will require additional repairs. Additionally, if you do not have all of the necessary tools and materials, you may end up spending more money than you would have if you had called a professional.
Replace Rather Than Repair
If your fiberglass tub is beyond repair, it may be time to replace it. A professional will be able to assess the damage and determine if the tub can be repaired or if it needs to be replaced. If replacement is necessary, a professional can help you choose a new tub and ensure that it is installed correctly.
In conclusion, while repairing a fiberglass bathtub crack can be a DIY project, there are times when it is best to call a professional. Whether it is due to extensive damage, lack of experience, cost, or the need to replace the tub altogether, a professional can ensure that the job is done correctly and efficiently.
Preventing Future Damage
Taking preventative measures can help avoid future cracks and damage to your fiberglass tub. Here are some tips to consider:
- Avoid placing heavy objects on the edges of the tub, as this can cause cracks over time.
- If possible, consider using a shower mat to prevent slips and falls. This can help prevent accidental damage to the tub.
- When cleaning the tub, avoid using abrasive cleaners or scrubbers that can scratch the surface. Instead, use a mild cleaner and a soft cloth or sponge.
- If you have a cast iron tub, be aware that it can cause damage to the fiberglass if it is dropped or bumped against it. Be careful when moving heavy objects in the bathroom to avoid any accidental damage.
- Normal aging of the tub can cause it to become brittle and more prone to cracks. Consider refinishing the tub every few years to help maintain its structural integrity and prevent future damage.
By following these preventative measures, you can help extend the life of your fiberglass tub and avoid costly repairs in the future.
