My fitter said to use "no more nails" but didn't go into details about whether he left it a few days to set and I forgot to ask. This group advised me to glue three days before the fitter's visit, which is what I did.
I think one small section may have come loose in one corner; perhaps the floor was dusty and the glue could not take hold? The rest seems to be fine, touch wood.
I hadn't thought about melt glue guns. Is the glue that strong?
By epoxy what do you mean: Araldite?
Thanks, Stephen.
