Make sure the substrate is dry before bonding. Several things you can do, one is to put wedges between the outer Filon skin and the debonded substrate and park it is the sun for several days, use a hair dryer, or put some acetone in the area it will aid it drying the area as the solvent flashes off. If you use a polyurethane adhesive like Gorilla glue it is much more forgiving than epoxy when it comes to moisture because water will activate it. A lot of moisture will really activate it and it will foam rapidly causing large bubbles leaving a weaker bond. I said all this because when I fixed mine I could not get all the moisture out and used the polyurethane adhesive . It held for about 5 or 6 years and the disbonding came back. The other side held for about 9 years. Epoxy will be a stronger bond but too much moisture will weaken or prevent a good bond. I think HD sells a moisture meter that will give you a reading of the moisture content. Good luck on your project.
