In this blog post, we will answer the question: “How to fix fiberglass delamination?” We will discuss the causes of fiberglass delamination and how to fix this issue. We will also talk about a few DIY delamination tips and the uses of a fiberglass delamination kit. In addition, we will describe a few key points to consider when doing to process on your own.

How to fix fiberglass delamination?

To fix fiberglass delamination, you will need to follow a few simple steps. 

  • First you need to make sure to identify the delamination area before you start the work. 
  • Use tape to mark the affected areas so you don’t lose track. 
  • It is also important to cover the area around the infected area. This can be done by using a combination of plastic and tape.
  • You will need to purchase a sealant to treat the affected area. 
  • Working from the bottom to the top is the best way to go about injecting the bonding agent. 
  • You will need to inject the agent above the infected area. 
  • Add pressure to the treated area immediately to avoid the liquid from running down to the side. 
  • It is also advised to mix the components in small batches. 
  • The mixture can react and dry fast, mixing a little can also help you to work more quickly.
  • Never use the same syringe and tubing on the same applications. 
  • Use a new one every day and use clamps in case of a bigger project. 
  • Before treating a section, be sure to test it. In most cases, the fiberglass delamination is extensive. 
  • Taking your motorhome to a repair shop can be expensive and you should be ready to spend some extra bucks.
  • Remember that there can be multiple layers of delamination and this will need extra work. 
  • Make sure that the resin is injected properly and is spread equally to all parts. 
  • You might be required to add extra pressure so that it sticks well. 

Use a fiberglass delamination kit 

There are plenty of fiberglass delamination kits that can help you do this process on your own. DIY fiberglass kits are easy to use and they are not too expensive. Fiberglass delamination kits can be priced anywhere from $100 to $300. You can purchase these delamination kits online and most people do these projects on their own.

Use enough syringes and wedges 

  • Purchase a bunch of syringes and used one each day. Around 10 syringes should be enough for you to get the job done. 
  • If the damage is on a large scale, it is always better to get in touch with a professional. However, fiberglass delamination cannot go unnoticed. The moment you find a few spots, it’s best to start working on them.
  • If you are using a clamping system, make sure you have enough wedges. You will need enough wedges and a good amount of wood. You might need more than 10 to 15 blocks of wood or wedges to get the job done properly. 
  • Make sure you have all the necessary stuff before starting the repairing process. The good news is that delamination is not permanent and it can easily be fixed.

Use a pump kit 

  • You can use wood panels or purchase a container pump kit. This will help you to calculate how much resin is required when working on delamination. 
  • The pump kit can help you mix the resin properly and also help to get the right consistency. 
  • Remember that smaller batches are recommended as large quantities can get dry up faster.
  • Use four to five ounces per batch since you can work faster. 
  • The pump kit will help you in the measurements and also help you to work faster. 
  • Reusing the tube and the syringe is not recommended since they can surely cause damage or even spoil the flow of resin. The insides of the tube and the syringe can dry up easily.

Many people try to clean out the syringe and the pipe but it will not help the resin to move as smoothly as it did the first time. Since the resin is can dry up quickly, there can be a lot of buildup on the inside and this can make the resin think or even cause a block. Overall, working on the same syringe and tube is not a good idea.

Use enough delamination sealant 

There are many sealants made for this purpose. These sealants are used on leads along with windows and edges. Different types of sealants are used. Sealant tape and self-leveling lap sealants are some of the other options that can be used. Another way is by using epoxy resin along with a slow hardener.

DIY delamination tips 

  • You will need to strip the sides of the RV walls and clean the surface properly. 
  • You will need to remove the old sealant before fixing a new one. 
  • Properly clean all the seals before resealing them. 
  • The surface should be able to contact the sealant to stick properly. 
  • Purchase a good quality sealant that will fix the issue and last longer.

Hire a professional 

Hiring a professional to get the job done can be easy, but it is sure to cost you extra. Fiberglass delamination can be annoying and it’s also advised not to keep delamination for long. When purchasing a used motorhome, it is important to check for fiberglass delamination. Fiberglass is prone to delamination as many factors could affect it.

Fiberglass delamination can look terrible on the walls and it can spoil the overall look of your motorhome. Once you have figured out the cause, it’s time to get it fixed. Treating fiberglass delamination can take a couple of days and it can also be time-consuming. A professional can get the job done faster. 

Fiberglass delamination causes 

It is important to identify the causes of delamination to prevent it from happening.  Fiberglass delamination is very common in motorhomes that have their structure built out of Fiberglass. Most RVs are known for having fiberglass roofs. RV delamination is possible only with fiberglass roofs and there are a few steps to prevent this from happening.

  • Fiberglass delamination takes place when the thin lauan plywood is separated from the gel-coat. 
  • Water leaks can lead to fiberglass delamination and this can be a severe issue. 
  • It can also take place due to excessive strain on the walls of the RV.
  • Moisture breaks down the adhesives that hold the fiberglass layers on the wall of the RV. Due to excessive moisture, the fiberglass starts to bulge
  • Moisture and water are the main root causes of fiberglass delamination. This will cause more damage to the surface and also give a warped and ugly look.

The only way to prevent fiberglass delamination is by preventing moisture from getting in. The skin of the fiberglass is always prone to wear and tear. Inspecting the roofing and the areas that have fiberglass will help you know the condition of the fiberglass. The exterior walls of any motorhome are vulnerable, especially if the material is made up of fiberglass.

A few extra tips 

The first and most important part to consider is working from the bottom to the top. When the resin is injected it tends to drip down due to gravity and cause a messy experience. Once you secure the sections at the bottom, you can work your way up to the top by injecting more resin between the damaged areas.

Inject the resin into the area that you are treating. The key is applying pressure to the area that you have just treated. This is important since the resin will need to bond with the fiberglass. You can do that by applying pressure with your hand, but most people use wood by fixing them for a couple of hours or so.
