1. Transducer Face Surface Preparation and painted housings - Lightly abrade the surface using
Scotch Brite® to remove gloss. Thoroughly clean the areas to be painted with soapy water and
dry.
2. Surface Application:
•
Mask as necessary. Do not paint over mounting hardware, anodes, pressure sensors, etc.
•
Apply an even, thin layer (0.1mm, 4mil per coat) of antifouling paint. If more than one coat is
needed to reach the maximum thickness, allow each coat to dry for 16 hours.
•
When applying paint to the urethane faces, use extra caution to apply a smooth, thin coat of
paint.
If the H-ADCP includes the optional pressure sensor, do not block the sensor port. The sensor
port is a small hole in the center of the copper screw (see
anti-fouling paint application, tape-off the screw. Once the anti-fouling paint has cured, remove
the tape.
This means that the sensor port is not fully protected from bio fouling. Even though the sensor
port is surrounded by the antifouling paint, bio fouling may still build up on the copper screw
and eventually clog the sensor port. However, most organisms do not seem to find the small
amount of unpainted surface attractive. If it is logistically possible to periodically inspect/clean
the pressure sensor port, it is highly recommended. This tradeoff situation must be analyzed for
individual deployments. Unfortunately, the location of the deployment site usually dictates
action in this regard.
