I'll take a guess. Clean the glass, the submerge in photoflow (mixed to the right dilution) then let dry before coating?
The surfactant, when used, is added to the melted emulsion along with the hardener just before coating and is held at 40 deg C during the entire coating session.

This method does not work with all emulsions, and Photo Flo is not the best surfactant for use on glass as has been pointed out by Denise Ross and Mark Osterman. If used, it may need to be "assisted" by another surfactant.
