A Stepwise Guide on How to Fix Stripped Screw Holes in Fiberglass Boat

Step 1: Determine the Size of the Hole

First, determine the size of the stripped screw hole by measuring it with a tape measure. Next, add 1/8th of an inch to the diameter of the hole. This additional 1/8th inch will allow the epoxy resin to have a tight grip on the sides of the hole.

Step 2: Cut a Piece of Fiberglass Cloth or Mat

After you have determined the size of the hole, use a pencil and wax paper to trace a circle around the edge of the hole. Next, cut out this circle with scissors or a razor blade. This cut-out piece will be used to patch up the stripped screw hole.

If you want to make a circle out of fiberglass, first cut out a square that is 2 inches bigger on each side than the desired circle. Then, cut out the four corners of the square so that you are left with a circle.

Step 3: Wet Out the Fiberglass Cloth or Mat

Mix equal parts of epoxy resin and hardener in a measuring cup. Use a mixing stick to mix these two substances thoroughly.

Next, wet out the cloth or mat with the mixture of epoxy resin and hardener. To do this, lay the cloth or mat in the mixture and press it down so that it is fully saturated. If you are working with a larger surface area, apply the wet cloth or mat to it.

Step 4: Apply the Fiberglass Cloth or Mat to the Hole

Apply the wet cloth or mat to the hole, smoothing out any wrinkles with your fingers.

If you are using a mat, place it over the hole and then use a roller or your hands to press it down onto the surface.

Step 5: Apply More Resin

For this project you will need a cloth or mat, and resin mixture. First, place the cloth or mat in the desired location. Next, apply the resin mixture over the cloth or mat. Make sure to cover the entire area.

Step 6: Let It Dry

Allow the resin to dry for at least 24 hours.

Step 7: Remove Excess Resin

Once the resin has dried, use coarse grit sandpaper to remove any excess resin.

Step 8: Drill a New Hole

Use an electric drill and a hole saw bit to drill a new hole in the exact location as the old, stripped hole.

Step 9: Insert the Screw

You Can Screw in the New Screw

Now you can screw in the new screw. Be sure not to overtighten it.

Step 10: Finish Up

Use fine-grit sandpaper to smooth out the area around the new hole. Wipe away any dust with a clean rag. Your boat is now repaired!

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.
