Fiberglass Delamination

Hi I'm Charlie. I just noticed delamination on my class C Chateau. I was wondering if anyone has had this problem and what the cure might be.

Hi Charlie! That's unhappy news about your C. This forum is populated with owners of molded-fiberglass trailers, so we are not experienced with delamination. However, I also belong to the Good Sam/RV Net forum and have read some of the horror stories over there. A very few folks have tried re-gluing the sandwiched layers (applying pressure) if the underlying wood was not damaged by water intrusion. But I think the most common solutions tend to be (a) replacing the delaminated section, which is expensive or (b) trying to sell the unit to some poor shmuck who doesn't recognize the problem! I hope you won't be tempted to try 'plan b'.

That is a common problem with the laminated material used on many Motorhomes and stick built trailers.
It is commonly caused by water infiltration from a leak at a seam or at a window.
Window tracks should be cleaned regularly and have the drains checked to be sure they are open.
Unfortunately repairs involve panel replacement. Fortunately the progression can often be arrested or at least slowed when the water source is found and mitigated.
Of course some of the problem is defective material or workmanship, if your vehicle is not TOOO old you might contact the manufacturer to request some relief.

Might want to consider selling that leaky Class C and buy a trailer made by one of the manufactures listed in the drop-down list at the top of the page.

There are quite a few videos on YouTube of people doing DIY delamination repairs, drilling, filling and applying pressure. Good luck
