Drying times vary. For tiles distributed on Mosaicfilm's plastic sheet product, there is a wait of only 40 minutes before it can safely be peeled off. Other plastic sheet products call for a longer wait and perforation of the plastic to help drying. Consult your tile manufacturer for details. Follow up with grouting once the thinset is dry.
For further instructions on tile sheets in general, see our tutorial - Laying Mosaic Tile Sheets.
