If you’re like me, you take great pride in your boat and want to make sure it’s in perfect condition. But sometimes, even the most minor things can go wrong and cause big problems. One such problem is stripped screw holes in fiberglass boats. Luckily, there is a quick and easy fix for this! This article will show you how to fix stripped screw holes in fiberglass boat. So read on and get started!
Fiberglass boats are usually made with a hull and deck bonded together with fiberglass fabric and resin. The hull is the bottom part of the boat that sits in the water, while the deck is the top part of the boat that you stand on. A layer of foam is between these two parts that help to insulate the boat and keep it buoyant.
Summary: If your home suffers from drafty walls, there are a few things you can do to help fix the issue. First, make sure that the windows and doors are properly sealed. Second, install insulation on the inside of the walls. Finally, adjust the air conditioning or heating tomatch the outside temperature.
A Stepwise Guide on How to Fix Stripped Screw Holes in Fiberglass Boat
Step 1: Assess the Damage
Before attempting to repair a stripped screw hole in a fiberglass boat, examine the damaged area to determine the extent of the issue. Stripped screw holes can result from overtightening, wear and tear, or using the wrong size screw. Consider the size and depth of the hole, as well as the thickness of the fiberglass material, when planning your repair.
Step 2: Gather Necessary Tools and Supplies
To fix a stripped screw hole in a fiberglass boat, you will need the following tools and supplies:
- Protective gloves and safety glasses
- A cordless drill or hand drill
- Drill bits in various sizes
- A vacuum or brush for cleaning debris
- Marine epoxy or polyester resin
- Fiberglass cloth or mat (if necessary)
- Mixing container and stir stick
- Toothpicks, wooden dowels, or threaded inserts
- Sandpaper (80 to 120 grit)
- Clean cloth or rag
- Screwdriver or power driver
Step 3: Clean the Stripped Screw Hole
Using a vacuum or brush, clean the stripped screw hole and surrounding area to remove any dust, debris, or loose fiberglass material. This will ensure a proper bond when filling the hole with epoxy or polyester resin.
Step 4: Choose the Appropriate Repair Method
There are several methods for repairing stripped screw holes in a fiberglass boat, depending on the size and depth of the hole, as well as the thickness of the fiberglass material. Consider the following options:
- Epoxy or polyester resin filling: Suitable for small to medium-sized screw holes and thin fiberglass material.
- Fiberglass reinforcement: Ideal for larger screw holes or areas where additional strength is required.
- Toothpick, wooden dowel, or threaded insert: Effective for rethreading screw holes with minimal damage or when using the same size screw.
Step 5: Fill the Hole with Epoxy or Polyester Resin
If you choose to fill the stripped screw hole with epoxy or polyester resin, follow these steps:
- Mix the epoxy or polyester resin according to the manufacturer’s instructions.
- Apply the resin to the stripped screw hole, ensuring that it fills the hole completely and extends slightly beyond the surface of the fiberglass.
- Allow the resin to cure according to the manufacturer’s recommended time before proceeding to the next step.
Step 6: Reinforce the Hole with Fiberglass (If Necessary)
For larger screw holes or areas requiring additional strength, reinforce the hole with fiberglass cloth or mat. To do this:
- Cut a piece of fiberglass cloth or mat slightly larger than the stripped screw hole.
- Mix the epoxy or polyester resin according to the manufacturer’s instructions.
- Apply the resin to the fiberglass cloth or mat, ensuring that it is fully saturated.
- Press the saturated fiberglass cloth or mat into the stripped screw hole, making sure it adheres to the fiberglass surface.
- Allow the resin to cure according to the manufacturer’s recommended time before proceeding to the next step.
Step 7: Re-drill the Screw Hole
Once the epoxy or polyester resin has cured, re-drill the screw hole using a cordless drill or hand drill and an appropriately sized drill bit. Be sure to wear protective gloves and safety glasses during this process.
Step 8: Insert Toothpick, Wooden Dowel, or Threaded Insert (If Applicable)
If you choose to use a toothpick, wooden dowel, or threaded insert to rethread the stripped screw hole, follow these steps:
- Insert the toothpick, wooden dowel, or threaded insert into the stripped screw hole until it fits snugly.
- If using a toothpick or wooden dowel, trim any excess material flush with the fiberglass surface.
- If using a threaded insert, ensure that it is installed according to the manufacturer’s instructions, and that it sits flush with the fiberglass surface.
Step 9: Sand the Repaired Area
Using sandpaper (80 to 120 grit), sand the repaired area until it is smooth and flush with the surrounding fiberglass surface. Be careful not to damage the surrounding area or remove too much material, as this can weaken the repair.
Step 10: Clean the Repaired Area
After sanding, use a clean cloth or rag to remove any dust or debris from the repaired area. This will ensure a clean surface for reinserting the screw.
Step 11: Reinsert the Screw
Now that the stripped screw hole has been repaired, you can reinsert the screw using a screwdriver or power driver. Be sure to use the correct size screw and avoid overtightening, as this can cause the screw hole to strip again.
Step 12: Inspect the Repair
Inspect the repaired area to ensure that the screw is securely in place and the repair is flush with the surrounding fiberglass surface. If any issues are identified, repeat the relevant steps to address them as needed.
Step 13: Perform Regular Maintenance and Inspections
To prevent future issues with stripped screw holes in your fiberglass boat, perform regular maintenance and inspections. This includes checking for signs of wear or damage, tightening loose screws, and replacing damaged or corroded screws as needed. Additionally, always use the correct size screws and avoid overtightening to prevent stripping screw holes in the future.
By following these steps and taking the necessary precautions, you can effectively repair stripped screw holes in a fiberglass boat and maintain the integrity and durability of your vessel. Regular maintenance and proper care will ensure that your fiberglass boat remains in good condition for years to come. Remember that professional assistance is always recommended when dealing with complex repairs or issues beyond your skill level, and it’s essential to follow all safety guidelines and manufacturer’s instructions when working with fiberglass materials and tools.

Frequently Asked Questions
Can You Fill Holes in Fiberglass?
Fiberglass is a type of plastic that is most often used for home improvement projects, such as replacing window panes or repairing roofs. It can be difficult to fill holes in fiberglass because the material doesn’t hold any shape once it’s damaged.
One possible solution involves using a sealant or glue to attach the new pieces of fiberglass to the old ones. This will help them keep their shape and make it easier to patch them up later on. Alternatively, you could try injecting some form of flexible putty into the hole prior to installing the new piece of fiberglass.
Will Epoxy Resin Hold Screws?
depends on a variety of factors, including the type of screws and the specific application. That being said, most epoxy resins are generally effective at holding screws in place. Keep in mind, however, that epoxy may not be the best choice for screws that are particularly delicate or prone to breaking. Always consult with a professional when selecting screws and adhesives for a project.
Can Gelcoat Be Used as a Filler?
Yes, Gelcoat can be used as a filler. This is due to its high-performance characteristics and ability to resist water damage. Additionally, it has low toxicity and good adhesion properties, making it an ideal choice for filling in cracks and dents on boats or ships.
Can You Use Bondo on Fiberglass?
Bondo is a great product for repairing just about any surface. However, as with any other product, it may not be the best choice for repairing fiberglass. Fiberglass is a very delicate material, and even the slightest scratch can cause it to fail. If you decide to use Bondo on your fiberglass project, make sure to take extra precautions to protect the material.
