The main reasons for automatic paint peeling are as follows: 1. Problem phenomenon: Due to poor adhesion and bonding between paint film layers, pathological phenomena such as paint film peeling, flaking, blistering, and delamination may occur. 2. Problem causes: (1) Incompatibility between primer and topcoat, resulting in poor interlayer adhesion. (2) Contaminated surface with oil stains, moisture, or other impurities. (3) Improper surface treatment. For example, if wood surfaces are filled with putty or painted without sanding, the oil in the topcoat may be absorbed, causing peeling, or the wood surface may not be effectively sealed. (4) Applying topcoat before the underlying layer is fully dry. (5) Construction temperature is too low.
