(Surface Prep) Power Tool Surface Preparation in Shipyards

Picture for Coatings + Proceedings 2021-ALL Papers

Power tool cleaning has been a common method of surface preparation prior to coating application since the dawn of steel shipbuilding. Power tools are usually handheld pneumatic, or sometimes electric, devices that through impacting or abrasive action can remove coating and corrosion. Most commonly power tool cleaning has been used for re-work or coating repair associated with outfitting. Typically, power tools are limited to the touch up or repair of small areas or areas that cannot be accessed by bulkier equipment such as abrasive blasters.

Despite having lower production rates and lower coating performance compared to abrasive blasting, power tools are still a valuable option and are effective in the right circumstances. However, tools and techniques are constantly evolving and there is a need to generate the necessary data to allow shipyards to optimize procedure for power tool cleaning prior to coating application. With proper guidance and optimization of newer tools and processes there is a significant opportunity to reduce costs and improve the coating quality for both shipyards and the Navy

(Inspection) What Do You Really Need to Know to be a Good Coatings Inspector?

Product Number: 60-COAT_DEC21
Author: William D. Corbett
Publication Date: 2021
$20.00

The role of a Coating Inspector has evolved considerably over the past few decades, and the responsibilities have increased over what used to be a rather straightforward job: to verify that surface preparation and coating application meet the project specification requirements. Today there are week-long or multi-week basic and advanced coating inspection courses, specialty courses that are industry-specific (e.g., bridge, nuclear), courses that are substrate-specific (e.g., concrete coatings inspection) and even coating-specific (e.g., inspection of thermal spray coatings).

(Surface Prep) National Shipbuilding Research Program Surface Preparation and Coatings Panel SSPC 2

Product Number: 48-COAT_DEC21
Author: Arcino “Q” Quiero, Jr.
Publication Date: 2021
$20.00

This summary is a look at implementable work and a gage of the value of future work. The strategic implementation of Surface Preparation and Coatings Automation, Standardization and Digitization of Visual Inspection, and Surface Preparation and Coatings Training Certification Program could provide cost and schedule savings. Optimizing Power Tool Surface Preparation potentially will increase Shipbuilders safety, while reducing material and labor costs.

(Surface Prep) Don’t Let Your Eyes Deceive You

Product Number: 67-COAT_DEC21
Author: Kenneth E. Rossy / Alexander J. Petkas,
Publication Date: 2021
$20.00

A steel surface has been properly prepared to a white metal blast and it looks great … to the naked eye at least. But is it? Why is a surface that has the correct profile and appears to be perfectly clean typically not good enough? A standard abrasive blast will give you the profile and visible cleanliness, but how clean is it? Testing is the only way to determine. That is testing for conductivity, chlorides, and any other contaminants.
