Advisory Council

The opinion fact sometimes a positive favorable cles with is, opinion, polls.”

We must have impact on preserving our environment and our opportunity to do business within it, while influencing the regulations that govern our products and processes.

The WaterJet Technology Association (WJTA) major impetus to the creation of the association was to provide a means of service and communication within the industry, as epitomized by the biennial waterjet conferences.

Power Washers of North America (PWNA) continually support its membership by utilizing its publications, training programs, certification, seminars, and trade shows to stay on the cutting edge of new technology.

our mission was to define an industry devoted to the economics of taking care of things, improving instead of replacing.

We reached out for the help of, and recognition by, the coatings manufacturers to bring the goal of identity to reality.

A Primary Mission of the Council is to promote effective means of surface preparation in the maintenance industry using water and water/abrasive blasting techniques.

Checkpoints and final inspections shall be signed off by certified coating inspectors.

The implementing contractor shall maintain a certification program for blasters and painters working on the project.

The inspection shall be made jointly with the SUPERVISOR and the ship’s Commanding Officer’s representative, and shall take place prior to the commencement of any work by the contractor.

Heavily rusted or corroded area, damaged metal and holes in the structure or piping shall be documented and provided to ship’s force and Responsible Contracting Authority to determine if further structural evaluation or NDT is warranted and for possible repair before surface preparation.

5.3 DEGREASE / FRESH WATER WASH DOWN: Prior to surface preparation, remove all surface contaminants such as sea salts, grease and oil (hydrocarbons), loose rust; mud and marine growth with 3,000-PSI minimum fresh water wash down.

7.7 PAINT APPLICATION: The use of brush, rollers, single or plural component spray equipment is acceptable for application of the paint coat specified below.

16.1.5 In order to pass the checkpoint, any Appendices required by the certified coating inspector shall be up to date or completed and submitted to QA.

MAINTAIN SEPARATE LOG FOR EACH AREA / LOCATION, PREPARED OR PAINTED SURFACE, WHEN AN AREA IS DIVIDED INTO SEPARATE SECTIONS MAINTAIN A SEPARATE LOG FOR EACH SECTION, FOR NUMBER OF MEASUREMENTS TO BE TAKEN SEE NOTES BELOW.

The five spot measurements shall be made for each 10 m2 (100 ft2) of area as follows: a.

1.1 Cleaning, Surface Preparation and Painting Requirements for Potable Water Tanks.

1.2 If the PPI checkpoint criteria are met, the following table provides service life expectancy for the listed systems.

MSDS and manufacturer’s ASTM F 718 sheets, Shipbuilders and Marine Paints and Coating Product / Procedure Data Sheet for coating systems being applied for specified area.

4.14.1 Prior to use, painting equipment (pumps, hoses, and so forth) shall be flushed clean to remove any residual contaminants or other foreign matter.

Situations arise where very limited touch-up is required, and specified drying times have an adverse impact on ship’s schedule.

7.3.1.1 Two days wait between coats and two days wait after the final coat if the largest single touch-up area is less than 1 ft² and the total touch-up area is less than 4 ft².

NOTE: BETWEEN APPLICATION OF PAINT COATS, ENSURE A MINIMUM OF 48 HOURS OF DRYING TIME IS GIVEN AT A MINIMUM TEMPERATURE OF 70°F.

During application, immediately brush out any runs, drips, sags or puddles.
