If indoor, given its Spain, it'll have concrete underneath right? You don't need to take all the grout out, you need to create enough space/depth to allow the grout to hold.
I bet any money there is a tool/blade/head specifically for this purpose. Find out what it is then buy or rent it.
Is this indoors or out?
