SubscriberI have a small Casita fiberglass camper that someone had brushed white FlexSeal (rubber seal) on the bare fiberglass interior walls to seal some leaks. Now I need to adhere carpet to the walls for insulation. I’ve tried 3M 90 adhesive spray and doesn’t stick. What product will stick to this FlexSeal rubber paint that’s been brushed on my fiberglass walls?
Please advise

Thanks for the question Rick! Sorry to hear that the 3M™ Hi-Strength 90 Spray Adhesive did not work for your application. There may be some issues with the bonding surface area of the carpet not being large enough for the adhesive to hold, or perhaps the roughness of the applied rubber. However, if it is just an adhesion issue, 3M™ Rubber And Vinyl 80 Spray Adhesive is a similar spray adhesive designed specifically for bonding to vinyls and rubbers which may help solve your issue.
Please comment below if you’d like to share additional details that could help refine your options.
