I hope to file my kitchen floor soon and hope to start preparation tonight. All of my ground floor rooms have an asphalt floor and the kitchen is no different - I peeled back the lino under the cupboards to check. However, when I removed the lino last night I found bare asphalt under the cupboards as expected, but there were old floor tiles in the rest of the room. The house was built in the late 50's and I guess they could be original. They are only about 2mm thick and appear to some sort of plastic with a tar/paper backing. Some around the edges lift easily but most don't. Can I leave them if they are secure or should they all come up? I am concerned that the floor tile adhesive may not stick to them correctly. I have bought cerafix powdered floor tile adhesive from B&Q.
