American Navy submarines overhaul torbo wet sand blasting machines took part successfully in the repairs to American Navy submarines last year. In the painting unit the hull of the submarine "US Michigan" was freed of lead paint in a reliable, environmentally friendly and time-saving manner. During the overhaul the unit worked in two 12-hour shifts round the clock to blast clean and coat the ship's hull. By using our machines, as the Navy itself stated, they were able to complete the project in just 14 days and save a total of 10,000 man-hours and almost half a million dollars. In order to be able to bind the lead components of the paint, a special additive was put into the abrasive blast mixture in the tank. An environmental-friendly inhibitor on a water basis prevented the freshly blast-cleaned metal from rusting.
