The film shows the kokuso being applied to an initial brownish-coloured bedding layer consisting of cellulose powder and micro-balloons mixed with Paraloid B72. The kokuso used at this stage is softer, i.e. has a lower sawdust content, than usual - this is because it is being applied to act as a binder between the bedding layer and the standard, harder kokuso that will be applied in the next stage.
