I’m installing a new IKEA kitchen, including a laminate splashback. Various people in forums and also a kitchen installer I got advice from are suggesting that the tiles should be removed before installing the new splashback. I’m removing the tiles from the walls which are only partly tiled (there are two small areas like this), as the edge will be visible and I don’t want to be able to see the combined thickness of the old tiles and new splashback.
For the wall behind the worktop, there will be no visible edge so the only problem that I can see is that we’ll loose 10mm so of space in the room by not removing the old tiles. If I keep the old tiles they will be roughed up to ensure a good bond to the new splashback.
I’m reluctant to go to all the effort of removing tiles and replacing the plasterboard wall if it’s not necessary.
Am I missing something? Why is it commonly recommended to remove the old tiles?
