Eleven proprietary protective coatings of differing composition, formulated for application to damp or immersed surfaces, and a quick-setting hydraulic cement material were procured for testing to determine their applicability for underwater maintenance painting. They were applied to dry steel, to steel wetted with fresh water, and to steel immersed in fresh and salt water. Variations in test methods included surface preparation (abrasively blasted, water blasted, and wire brushed), application (hand/glove, putty knife, brush, and roller, as appropriate), and water (fresh and salt). The coated steel specimens were subsequently subjected to a pull test to establish the film properties. Coatings, paints, steel, maintenance, hydraulic cement, immersed surfaces, underwater construction, underwater painting. (jes) |
