Pause between user mouse clicks

I'm trying to make a grid turn based game and I want the user to be able to click on the grid, then have a pause function that does not let them click anywhere for 2 seconds or so then after this duration they can make another move. I've tried disabling the colliders on the grid I am using in the on mouse down event, then reenabling them using both Coroutine and invokerepeating with no luck. Is there a correct general way of either disabling clicking on screen or some other way of doing what I am intending?

Thanks!
