protecting the aluminium floor of the horsebox

[VRIN]

Hi
I have a horsebox with an aluminium floor with rubber mats on top. My horse has 'wee'd' on it a few times of late during a long journey so I though I would life the mats to ensure it wasn't wet underneath. Well it was wet in places. I am now wondering about laying them back down - they appear to have been stuck down with something - not sure what. The floor is fine but I am wanting to ensure it remains so. Is there something that I can use to stick the mats back down?

Make sure you have plenty of drain holes in the aluminium floor and rubber you need to put them where the pee is not draining on to something else ( like in my first lorry the gas bottle , delightful that was not ).
