CDA Quality Control & Process Improvement 2

Question 1

When evaluating a finished decorative paint project, which method best identifies subtle color inconsistencies across a large surface?

Accepted Answer

Raking light inspection at a low angle

Answer

Raking light at a low angle reveals surface variations, sheen differences, and lap marks that are invisible under direct overhead lighting.

Question 2

A decorative artist notices that a glazing medium is drying too fast, causing brush marks to show. What process improvement should be implemented?

Accepted Answer

Add an appropriate retarder to extend open time

Answer

Adding a compatible retarder extends the working time of the glaze, allowing the artist to blend and eliminate brush marks before the medium sets.

Question 3

Which quality control step is most critical before applying a decorative finish over a previously painted surface?

Accepted Answer

Testing adhesion of the existing paint layer

Answer

Testing adhesion ensures the existing paint layer is sound; poor adhesion can cause delamination of all subsequent decorative coats.

Question 4

A client reports that a decorative faux finish is showing uneven sheen months after completion. What is the most likely root cause?

Accepted Answer

Inconsistent topcoat application thickness

Answer

Uneven topcoat application creates areas of varying film thickness, which refract light differently and produce inconsistent sheen.

Question 5

In a process improvement context, what does a 'checklist audit' accomplish for a decorative painting team?

Accepted Answer

Ensures each step of the process is completed consistently by all team members

Answer

A checklist audit standardizes workflow by confirming that every procedural step—surface prep, priming, application, topcoating—is consistently performed.
