How do I stop my RV from delaminating?

Prevention of delamination is simple: Seal every seam at least once every 5 years. I’d recommend even sooner than that depending on where you live, how much you use your RV or travel trailer and what your climate is.

Method 1: Remove Gel Coat Oxidation From Your RV by Hand Buffing

  1. Apply product to a simple kitchen non-scratch scrub sponge.

What causes delamination on an RV?

Delamination is when the fiberglass or gelcoat outer layer of an RV starts to pull away from the substrate, usually luan or a light weight plywood. Delamination begins as small cracks and then starts to spread outward. These cracks can start as stress cracks, but are mostly accelerated by water intrusion.

Can heat cause RV delamination?

I too would question that exterior/interior temperature extremes could cause delamination. As Bob pointed out, almost all delamination is caused by water or moisture penetration into the layers of plywood, fiberglass and gel coat.
