I would be careful with solvents, only cause your dealing with plywood.........
I tore out the carpet in our Casita
. What a chore! You would have thought they were trying to prevent a theft of carpet. Glued all over....... With the Casita
it's attached to fiberglass with this rubber stuff on top of it. Anyway, the only suggestion I have would be to scrape, scrape, scarpe!!!!
I guess you could try asking where you purchased your Alllure from if they have any suggestions. But I would be leary of using any solvent on plywood.
Get your scraping on!
