Techniques 1
[ phase 3 ] Preparation
of the semina bed
After the setting of the decorations we procede
with the laying down of
a semina bed made from lime, sand and grounded bricks.
The bed can be in a powder form with a thickness of around
1.5 to 3cm (instead of a paste). The grit is laid down in
three separate phases on top of this layer: the first using
a large quantity of granulometries; the second with a medium
amount,
and the final phase using a smaller amount. In this way all
of the mixture is compressed.
Finally, this is pressed with a roller to consolidate the
grit and the foundation. <<
