Which of the following are common defects found in paint finishes?

• A. Fading and discoloration
• B. Blistering, bubbling, cracking, and peeling
• C. Pouring and layering
• D. Chalking and rusting

Answer: (B)

Blistering, bubbling, cracking, and peeling are indeed some of the most common defects found in paint finishes. These issues often arise due to poor surface preparation, moisture entrapment, or the use of incompatible materials. Blistering and bubbling occur when air or moisture is trapped beneath the paint layer, causing it to lift away from the substrate. Cracking usually results from the paint film becoming too dry and hard, leading to a lack of flexibility. Peeling happens when the bond between the paint and the underlying surface fails, often due to environmental factors or inadequate adhesion. While fading and discoloration, and chalking and rusting, can occur in paint finishes as well, they are generally not classified in the same category of defects specifically related to immediate paint application issues. Pouring and layering, on the other hand, are not recognized terminology for defects in the context of paint finishes.
