Thanks for the replies, I take it the film on the tiles has to be
removed before the grout sets!

Yes, especially with epoxy. With ordinary grout, if the film left when
the tiles are dry doesn't polish off with a cloth you can use grout
remover (acid) to dissolve it away. Once epoxy sets you won't shift it.
OTOH polish the tiles with a damp cloth before the epoxy goes off to
ensure no residual stickiness of the surface and when it's all dry the
finish is perfect.
