Back Splash Tile Over Old Sheet Rock?

Stcrosby

Happy New Year DIY Family,
I'm remodeling our 1955 cape's kitchen. We just had granite counter tops installed and I am going to install a tile back splash(for the first time in my diy career)with 3/4-1" sheet tiles. Previously there was a thin sheet 1/8" of laminate covering the sheet rock attached by glue as the back splash. When I removed the laminate it began to pull the first layer of paper off the sheet rock.
My question is: do I tile directly over the old sheet rock?
or do I put up a thin peice of ply wood over the sheet rock and then adhere the tile to the plywood?
I have 5 electical outlets already set at 3/4" - 1" out
Open to any and all suggestions and thank you in advance!

As you saw, clearly I don't know much but I was told that would be fine. Got my first few rows of tile up right now so I hope that's correct!

(Thanks for your responses to my question!)

I believe i found the answer to my own question; I think I'm going to use 1/4" cement backer board applied directly to the sheet rock.
Has anyone had success with this or is cement backer board only to be applied to the studs?

You can put the backerboard over the drywall. Tile backsplash is often placed directly on the drywall, because there's not much chance of a lot of water getting through to cause damage. You will need a fairly flat surface though. If the face paper on the drywall has been compromised by removing the old laminate backsplash, it may be easier to add the backer rather than try to smooth out the drywall....
