How to Repair a Fiberglass Ladder

If you’re like most people, you probably don’t have extra money lying around to spend on a brand new ladder. Learning how to repair a fiberglass ladder may be just what you need. This blog post will walk you through the steps to repair a fiberglass ladder.

How to Repair a Fiberglass Ladder

Remember that fiberglass ladders can be quite dangerous if not repaired correctly, so follow all the steps exactly as outlined below. If you’re lucky, it’s just the bottom rung that has broken off your ladder. Here are a few tips to help get you started.

Summary: If you notice that your ladder is starting to show signs of wear, there are a few simple steps you can take to help it stay in good condition. First, keep your ladder dry. If it’s wet, the fibers in the ladder will start to bond together and create cracks. Second, make sure your ladder is stored in a safe place. If it falls over, the joints between the rungs will become stressed and eventually break. Finally, take care when using your ladder. Be sure to use the correct grip, and don’t stand on the top rung.

What Tools and Supplies You’ll Need

  • Razor knife
  • Medium-grit sanding sponge
  • Silicone caulk
  • Fiberglass mesh tape or heavy fiberglass fabric
  • Bondo or resin
  • Mixing cup, stir sticks, and popsicle sticks
  • Wood putty

Step by Step Guide: How to Repair a Fiberglass Ladder

Step 1: Remove the Broken Sections

The first step in repairing a fiberglass ladder is to remove any broken sections. You can do this by drilling a hole through the center of the break and using a hacksaw to cut through it. A reciprocating saw can also be used for this, but you will need to have safety glasses on because the glass will fly everywhere as you cut.

Step 2: Clean the Broken Segments

Next, clean the broken segments, removing any remaining pieces of the old ladder and sharp edges that could cut someone or damage the surface your new ladder will be placed on. A wire brush should remove all of the old frames.

Step 3: Prepare the New Frame Segments

The next step is to prepare the new frame segments by cutting them to fit together and onto your existing ladder. A hacksaw or reciprocating saw would be useful for this, but a table saw would be even better if you have access to one.

Step 4: Glue the New Frame Segments

The next step is to glue the new frame segments together. This is done by applying wood glue onto both surfaces and then stacking them up to fit together tightly. You will need to use some pressure when doing this so that the glue spreads to all surfaces. Some clamps may be helpful here!

Step 5: Check Alignment

The next step is to ensure that your new frame segments are aligned correctly with the existing ones – this is crucial so that you don’t have any issues later on. If they are not, you should use a mallet to tap them into place.

Step 6: Using Epoxy for Permanent Repair

The final step in repairing a fiberglass ladder is applying epoxy resin on your new frame segments so that they are secured tightly and permanently. You can do this with some sandpaper, although you should wear gloves while doing so because the epoxy is quite abrasive. Make sure you don’t have any cracks or holes in this resin before doing so!

Step 7: Let the Epoxy Cure

After letting your new fiberglass ladder dry for a day, it will be cured and rigid so that it can support weight without bending or breaking. Once this is done, you can use it as normal!

Step 8: Use Your Fiberglass Ladder!

The final step is to use your fiberglass ladder. This should give you many years of service, and the new sections should be just as sturdy as the original ones. Then, if anything does happen, you can repeat the process to fix it or replace these sections with new ones if needed.

Sealing a Fiberglass Ladder to Prevent Shedding

Now that you know how to repair a fiberglass ladder, you can follow the steps to get the solutions. But there are still some things that you need to know, like sealing it, to prevent shedding in the future. So the first thing you should do to maintain a fiberglass ladder is to keep it dry.

While rain and water won’t damage the fibers that make up the structural part of the ladder, those same fibers will absorb moisture from things like dew or humidity. Once water gets into the molecular structure of these materials, it can only be removed by evaporation.

This moisture will cause the structural fibers to expand, eventually leading to cracking and breaking your ladder. To prevent this from occurring, you need to seal the ladder against moisture (water and humidity) in any form. Even if your ladder is stored in a shed or garage, humidity can still get to your ladder over time.

There are a few ways you can go about preventing this moisture from occurring:

1. Paint the Ladder:

The easiest way to deal with an existing fiberglass ladder is to paint or prime it. While this may seem like a good idea at first, it might not be the best thing you can do to protect your ladder. However, if you’ve ever painted anything before, the chances are excellent that you know about paint adhesion.

Paint needs something to adhere to, bind correctly, and create a lasting effect. If the paint is applied to a surface that doesn’t have enough texture or grip, it could chip and flake off the first chance it gets. In this case, the paint may not be the best way to seal your ladder because you need water to run off of it as quickly as possible.

2. Use a Water Repellant:

A water repellant is a substance that can be sprayed on your ladder to seal it and prevent any additional moisture from getting in. While you may think that this sounds like the best idea, it doesn’t necessarily provide anything but an initial barrier.

Water repellants will increase the ability of water to pass through them over time, which means that the protection it provides will be short-lived. To maintain a water-repellant, you’ll have to re-apply it every 1-2 years.

Increase the Ability of Water

3. Use a Silane Based Water Repellant:

Silane is a very popular chemical compound used in different applications for many different reasons. However, when it comes to some of the most common uses for silane, you can find it as an adhesive in things like fiberglass cloth. Water doesn’t pass through this type of material because it’s made up of very small fibrils that are woven together with a chemical bond.

These materials are considered to be very strong, which is why they’re used in so many different applications. In the case of silane-based water repellants, it’s best to have a professional handle the application. If you choose this option, it will cost you several hundred dollars to have someone come out and do it for you.

4. Silane Water Repellant Kit:

A much cheaper alternative to hiring someone to apply a silane-based water repellant is just to purchase one for yourself. You can find these kits at your local hardware store for much less, but be prepared to pay much more because you’ll have to do all the work yourself.

While it may require elbow grease and dedication, the process is simple and relatively fast. Once applied, you should have a water-resistant ladder that can be used in all kinds of applications without taking any extra steps between uses.

Can a Cracked Fiberglass Ladder Be Repaired

Sections of fiberglass ladders can be repaired if they become cracked. The cracks are usually tiny, but you can have them repaired by a professional fiberglass repair company rather than replace the ladder. Fiberglass is easy to work with and fairly inexpensive, so you can expect your ladder to look as good as new again after it is repaired.

Fiberglass Is Easy to Work With

All that usually needs to be replaced are the cracked sections, which will be cut out and replaced with new fiberglass material. Your ladder won’t have any weak spots once it’s fully repaired. Additionally, the crack itself may have made the ladder unsafe to use.

Because professionals will not only replace the broken section but also check the ladder to ensure it is safe for use, you can rest assured that your problems have been solved and you’ve saved yourself the trouble of needing to buy a new ladder.
