Objective:
The project will work with a stakeholder team to:
- Determine the various levels of surface preparation currently implemented.
- Determine adhesion and performance effects of the differing methods to find optimal performance.
- Identify and share best practices among shipyard coating experts.
Summary:
This project will evaluate the effects different surface preparation methods or desired practices have on interior non-critical areas (bulkhead and overhead) over varying timeframes of the construction process. During the build sequence, primer application occurs in various non-critical areas. Topcoats are applied much later in the build sequence closer to final assembly and closeout. By the time this stage is reached published recoat windows for the primers are often exceeded. These areas then receive various levels of surface preparation to reactivate the surfaces for topcoat application. This part of the process is time- and labor-intensive.
Key Deliverables / Benefits:
This project seeks to reduce time and labor effort by reviewing multiple levels of surface preparation and desired overcoating practices to determine which is the best course when recoating windows have been exceeded.
