No, you cannot tile directly onto EGGER Peel Clean Xtra. It is difficult to adhere anything to the polymer layer that is left on the boards once the Peel Clean Xtra film is removed.
Mechanically fixing a more appropriate board, plyboard for example, using nails or screws onto the Peel Clean Xtra boards and adhering a Schluter Ditra matt would provide a suitable surface.
For those wanting to tile directly onto board, we recommend using EGGER Protect as it can be tiled onto directly.
