The community relations exercise was co-ordinated by the Rotary Club of Patong Beach, and the Navy League Phuket, with about 60 sailors taking part.
Rotary club member Boon Pongchiboon said the club provided the equipment and materials, and the US Navy provided the man-power.
The painting took place from Monday to Wednesday this week, with about 20 volunteer sailors helping out each day.
“We have pretty much done community work in most of the places we have been,” said USS Ronald Reagan crew member Chris Chinery, 33. “Sometime we pick up rubbish, or sometimes we paint like this.
“Of course, it make us feel good that we can do something beneficial for local communities.”
