While you have the terrain you want selected, hover your mouse over the spot you want to change and press x. Or, alternatively, hold x and just drag your mouse over all the tiles you want changed. It's the toggle for the terrain mode.

Weird question but is there a way to change the size of the brush to preform the change on multiple tiles?

No worries about the question! No, there isn't, unfortunately.
