Hi again, PVA glue is a gloopy white glue that is used everywhere here from Schools to crafts to mending things, you can buy it in tiny pots at stationers or by the gallon in DIY stores, because you can also use it to prime a surface to help adhere render etc.
It is thick and looks like yoghurt or cream, but sticks beautifully. I think it might be worth trying it on a little bit of scrap and seeing if it will wash out, that would be the main thing, wouldn't it?
You wouldn't think there would be a language barrier between two English speaking nations would you?
best wishes
