FiberFix

FiberFix is a heavy-duty fiberglass repair tape designed to create extremely strong repairs for broken tools, pipes, furniture, and household items. Once activated with water, the tape hardens into a rigid material similar to steel, allowing users to permanently reinforce damaged objects.

The product became widely known after appearing on Shark Tank, where the founders demonstrated the strength of the repair tape by fixing broken tools and other objects during their pitch.

After securing a deal with investor Lori Greiner, FiberFix quickly grew into one of the most recognizable repair products from the show. Today, the tape is widely used for home repairs, automotive fixes, and outdoor equipment maintenance.

Key Highlights

• Industrial Strength Repair Tape
• Activated with Water
• Shark Tank Deal: Lori Greiner invested $120,000 for 12% equity

Following the episode, the product experienced a significant surge in sales as millions of viewers discovered FiberFix for the first time. The national exposure from the show helped the brand quickly gain popularity among homeowners, DIY enthusiasts, and repair professionals.

As demand increased, the company expanded its distribution and began appearing in major retail stores, hardware chains, and online marketplaces. This broader availability allowed FiberFix to reach a much larger customer base and helped establish it as a well-known repair solution for both household and professional use.

The Shark Tank Pitch

During their appearance on Shark Tank, the founders of FiberFix demonstrated how the repair wrap could fix broken objects and create a rigid bond far stronger than traditional duct tape. The live demonstration showed how the fiberglass tape hardens after activation, forming a tough shell around damaged items.

The entrepreneurs entered the Tank seeking $90,000 for 10% equity in their company. They explained how FiberFix could be used for a wide range of repairs, including fixing tools, pipes, sports equipment, furniture, and outdoor gear.

The Sharks were impressed by the product’s strength, versatility, and simple application process. Because the tape activates with water and hardens quickly, it offers a practical solution for both household repairs and emergency situations.

After negotiations, Lori Greiner offered $120,000 for 12% equity, and the founders accepted the deal.

The investment and exposure from the show helped the company expand production and grow distribution, allowing FiberFix to reach customers through major retailers, hardware stores, and online marketplaces across the United States.

How FiberFix Works

FiberFix is made from industrial-grade fiberglass material combined with a water-activated resin. When the material comes into contact with water, a chemical reaction begins that causes the wrap to harden into a rigid and durable structure.

To use the tape, the user simply follows a few basic steps:

1. Activate the tape with water to start the curing process.
2. Wrap it tightly around the damaged object, ensuring the fiberglass layers overlap and form a secure hold.
3. Allow the tape to harden, which usually takes only a short amount of time.

Once fully cured, the wrap becomes extremely strong and rigid, forming a solid outer shell that reinforces the damaged area and helps create a long-lasting repair.

Key Features

Fiberglass Reinforced Material
Made from durable fiberglass fibers designed to create a strong structural bond.

Water-Activated Repair Tape
The wrap is activated simply by applying water, which starts the curing process.

Hardens Like Steel
Once cured, the material forms a rigid shell that provides strong reinforcement.

Heat and Weather Resistant
The hardened material can withstand exposure to heat, moisture, and outdoor conditions.

Works on Many Surfaces
The repair tape can be used on metal, plastic, wood, fiberglass, and many other materials, making it a versatile solution for a wide range of repair situations.

The Story Behind the Idea

The idea for FiberFix came from the founders’ desire to create a stronger and more durable alternative to traditional repair tapes. While products like duct tape are widely used for quick fixes, they often lack the structural strength needed for long-term repairs.

The entrepreneurs set out to design a product that could provide a permanent reinforcement rather than just a temporary patch. Their solution was to combine fiberglass fibers with a water-activated resin, creating a repair wrap that hardens into a rigid, durable material once applied.

When the wrap is activated with water and wrapped around a damaged object, the fiberglass and resin cure into a strong outer shell. This hardened layer can reinforce broken handles, pipes, tools, and other equipment, making the repair significantly stronger than typical tape solutions.

The founders later brought their invention to Shark Tank, where the demonstration of the product’s strength impressed both the investors and the audience. The appearance on the show introduced FiberFix to millions of viewers, dramatically increasing brand awareness and helping the product gain widespread popularity.

Why FiberFix Became So Popular

Several factors contributed to the success and widespread popularity of FiberFix. The product combines strength, simplicity, and versatility, making it useful for a wide range of repair situations.

Extremely Strong Repairs
One of the biggest reasons for FiberFix’s popularity is its exceptional strength. The fiberglass material hardens into a rigid structure once cured, creating a durable reinforcement that can hold broken items together far more effectively than traditional tape.

Easy to Use
The repair process is simple and straightforward. Users only need to activate the wrap with water, apply it tightly around the damaged object, and allow it to cure. Within a short time, the material hardens and forms a strong protective shell.

Versatile Applications
FiberFix can be used to repair a wide variety of objects, including tools, pipes, furniture, sports equipment, garden tools, and outdoor gear. This versatility makes it a practical addition to many toolboxes and repair kits.

Shark Tank Exposure
Appearing on Shark Tank helped introduce the product to a national audience. The demonstration of its strength impressed viewers and investors, which led to increased demand and helped the brand expand into retail stores and online marketplaces.

FiberFix vs Duct Tape

Who Should Use FiberFix?

FiberFix can be useful for many people who need a strong and reliable way to repair broken items quickly. Because the fiberglass wrap creates a rigid and durable bond once it hardens, it can help reinforce damaged tools, equipment, and household objects.

People who may benefit from using FiberFix include:

• Homeowners performing household repairs, such as fixing furniture, handles, or damaged equipment
• Mechanics and DIY enthusiasts who frequently work on tools, machines, or vehicles
• Outdoor adventurers who may need quick repairs for gear while traveling or exploring
• Campers and survivalists who value durable repair solutions for emergency situations
• People fixing broken tools, pipes, or sporting equipment

Because it is compact, lightweight, and easy to store, many people choose to keep FiberFix in toolboxes, garages, vehicles, or emergency repair kits. This makes it a convenient solution for unexpected repairs when replacement parts are not immediately available.

Is FiberFix Worth It?

For many users, FiberFix provides a powerful repair solution that is often much stronger than traditional tape or adhesives. The product uses a fiberglass-based material that hardens after activation with water, creating a rigid and durable bond around damaged items.

Once applied and cured, the fiberglass wrap forms a strong outer shell that can reinforce broken objects and help extend the life of tools, equipment, and household items. This makes it useful for repairing things like tool handles, furniture parts, sports equipment, plumbing pipes, and outdoor gear.

Another advantage of FiberFix is its versatility. Because the wrap molds to the shape of the object being repaired, it can be used on irregular surfaces where normal tape or glue might not hold well. The hardened material is also water-resistant and durable, making it suitable for both indoor and outdoor repairs.

Thanks to its strength, ease of use, and wide range of applications, FiberFix continues to be considered one of the most practical repair products ever featured on Shark Tank. For people looking for a quick and reliable way to fix broken items instead of replacing them, the product can be a useful addition to a home repair toolkit.
