Tiling over existing tiles in a cob cottage

I know it is not recommended but as we live in a very old cob cottage I would not like to remove existing tiles therefore if I score with an angle grinder the coat with PVA will this do the job. Existing tiles are very sound but have lost their glaze and it looks awful.

You can tile over existing tiles but I would remove them but if you want to just tile over them do not use pva as this only forms a skin on the surface and breaks down in time I recommend that you prime with sbr such as Bal bond.
