A wall can be wet, it doesn’t require a person to touch the wall before it can be called wet. So the sense of touch is not required for something to be wet.
It changes the property of something else to make it wet.
If the wall was dry and I add water to it I have changed this property, if the wall is already wet and I add water to it I have changed nothing. Therefore if I add water to something and do not change its properties then it was already wet in the first place.
If adding water to water does not change its properties then the water was already wet in the first place.

As I said, it changes the property of something else, a person does not need to be involved.
