3 Abrade the sonar head surface using a sanding paper with 240 inch grit size.
Do not exceed a surface roughness (R
max
) of 35 microns as this can influence the
EM 2040C performance.
4 Remove all dust.
5 Apply the primer, and let it dry.
6 Apply the paint.
Observe the instructions provided by the paint manufacturer. Use airless spray.
Apply the minimum specified film thickness per coat and for the complete layer.
It is not possible to measure dry film thickness on sonar head surface. You must
therefore use a wet film gauge to frequently measure the paint thickness.
Note
We strongly recommend that you do not use a paintbrush and/or a roller.
7 Allow the paint to dry.
Further requirements
The contractor or shipyard must keep a daily paint log recording all relevant information
from the surface treatment.
