RV delamination is a structural flaw that occurs when the fiberglass outer layer (or the gel coat layer) on the RV separates from the backing layer — generally plywood or luan. This can happen due to a variety of factors, including:
- Water damage: The most common cause of RV delamination is water damage. When water seeps into the RV, it can weaken the adhesive that holds the fiberglass and plywood together. This can lead to the layers separating.
- Manufacturing defects: RV delamination can also be caused by manufacturing defects. If the fiberglass or plywood is not properly bonded, it can lead to delamination over time.
- Impact damage: RV delamination can also be caused by impact damage. If the RV is hit by something, it can cause the fiberglass or plywood to crack or break, which can lead to delamination.
- UV rays: UV rays from the sun can also weaken the adhesive that holds the fiberglass and plywood together, which can lead to delamination over time.
RV delamination can be a serious problem, as it can lead to water damage, mold, and structural failure. If you see signs of RV delamination, it is important to have it repaired as soon as possible.
RV delamination can also weaken the structural integrity of your camper’s fiberglass. You may notice tiny hairline cracks in your camper’s fiberglass (hairline cracks in fiberglass can happen on your boat too).
Compared to hairline cracks, delamination is a serious problem. If you see any of these signs, it is important to have your RV inspected by a qualified RV repair technician. They will be able to determine if the delamination is a serious problem and recommend the best course of action for repair.
Here are some signs of RV delamination:
- Blisters or bubbles: Blisters or bubbles on the fiberglass surface are a common sign of delamination.
- Wavy or rippled surface: A wavy or rippled surface on the fiberglass is another sign of delamination.
- Loose or peeling paint: Loose or peeling paint is also a sign of delamination.
- Moisture or mold: If you see moisture or mold on the fiberglass, it is a sign that delamination has already occurred.
Luckily, there’s an easy DIY fix for hairline cracks that you can do yourself.
Hairline Cracks in Your RV Fiberglass
Hairline cracks in fiberglass are bad because they can allow water to seep in and damage the material. Fiberglass is a composite material made of glass fibers and resin. The resin is what holds the fibers together and gives the material its strength. When hairline cracks form, they can allow water to seep into the resin and weaken the material. This can lead to further cracking, delamination, and structural failure.
In addition to water damage, hairline cracks in fiberglass can also allow dirt, debris, and chemicals to seep in. This can also weaken the material and lead to further damage.
If you see hairline cracks in your fiberglass, it is important to repair them as soon as possible.
Steps to Fill Hairline Cracks
Here are the steps on how to fill hairline cracks in fiberglass:
- Prepare the area. Clean the crack area with acetone or rubbing alcohol to remove any dirt, grease, or oil.
- Widen the crack. Use a sharp tool, such as a utility knife or a Dremel tool, to widen the crack slightly. This will help the filler to adhere better.
- Remove any loose material. Use a vacuum cleaner or a brush to remove any loose material from the crack.
- Apply the filler. Use a putty knife or a syringe to apply the filler to the crack. Make sure to fill the crack completely.
- Smooth out the filler. Use a damp cloth or a sanding block to smooth out the filler.
- Allow the filler to dry. The filler will typically dry in a few hours.
- Paint or coat the area. If desired, you can paint or coat the area to match the surrounding surface.
Here are some materials you can use to fill hairline cracks in fiberglass:
- Fiberglass resin: This is a two-part epoxy that is commonly used to repair fiberglass. It is strong and durable, and it can be tinted to match the surrounding surface.
- Fiberglass cloth: This is a thin, woven material that is used to reinforce fiberglass repairs. It can be applied to the crack before the resin is applied.
- Epoxy putty: This is a pre-mixed epoxy that is easy to use and dries quickly. It is not as strong as fiberglass resin, but it is a good option for small repairs.
If the crack is large or deep, you may need to use a more specialized repair method, such as a structural repair kit.
Here are some tips for filling hairline cracks in fiberglass:
- Work in a well-ventilated area. Epoxy fumes can be harmful.
- Wear gloves and eye protection to protect yourself from the chemicals.
- Be patient. It takes time for the filler to dry completely.
- Test the filler in an inconspicuous area to make sure it matches the surrounding surface.
