Correct Answer

A. Poor Alkali

Explanation

Poor alkali resistance refers to the inability of the paint film to withstand alkaline substances. In the context of fresh masonry, poor alkali resistance can lead to color loss and overall determination of the paint film. This means that the paint may fade or deteriorate when exposed to alkaline substances commonly found in masonry surfaces. This can result in a poor appearance and reduced durability of the paint job.

Correct Answer

A. Poor Galvanized Metal Adhesion

Explanation

The correct answer is "Poor Galvanized Metal Adhesion". This refers to paint that has lost its ability to stick to a galvanized metal surface. This can occur due to a variety of factors such as improper surface preparation, incompatible paint formulation, or poor quality paint. When the adhesion is poor, the paint may blister, peel, or flake off the metal substrate. It is important to ensure proper adhesion to galvanized metal to maintain the integrity and durability of the painted surface.

Correct Answer

A. Poor Gloss Retention

Explanation

Poor Gloss Retention refers to the deterioration of the paint film, leading to a significant or rapid loss of shine in the top coat. This means that the painted surface loses its glossy appearance over time. It could be caused by various factors such as exposure to harsh weather conditions, improper surface preparation, or the use of low-quality paint. This problem can affect the aesthetic appeal of the painted surface and may require repainting or refinishing to restore the desired gloss level.
