Hi
Our kitchen sink had a black mat stuck to it's underside. It has fallen
off. Does anyone know the purpose of this mat? Is it for sound
deadening (as water flow into sink from taps) heat retention for hot
water.
If it has to be stuck on what's the best adhesive?

It's for sound deadening.

Evostik will stick it - the proper solvent one, not the toy mimsy version.
