Which outcome would be flagged as a problem by a quality control checklist when different finishing methods are used side by side?

• A. Difference in colors
• B. Consistent gloss
• C. Uniform aggregate distribution
• D. Even edges

Answer: (A)

When different finishing methods are used side by side, the surface should read as a single, uniform layer. Any color variation across the finish is a sign of inconsistency in how the surface was treated, which is exactly what a quality control checklist looks for. This color difference can come from using incompatible finishes, different pigment batches, or varied curing and absorption between areas, all of which create an obvious visual mismatch. That mismatch is undesirable because it suggests the surface isn’t uniform in appearance, and it can hint at underlying inconsistencies in the material or application that could affect performance or long-term durability. The other outcomes—consistent gloss, uniform aggregate distribution, and even edges—indicate a well-executed, uniform finish and would not typically be flagged.
