2. The second reason for the paint peeling is that some paints have poor adhesion and cause paint peeling. There are two reasons for poor adhesion:
(1) Some species of wood contain extractive components, such as phenolic compounds, which have a polymerization inhibitory effect on the polymerization reaction of free radical-initiated UV coatings, resulting in poor adhesion of the paint film and delamination of the paint film. Severe peeling occurs.
(2) Before the paint on the wooden floor, the moisture content of the floor is too high (moisture content is more than 12%). Because the moisture content is too high, although the surface is coated with paint, when the external environment changes, the water inside the wood will evaporate outwards. Internal stress changes, resulting in uneven force, resulting in cracking, peeling and other serious quality accidents.
Although you mentioned the phenomenon of paint peeling in the letter, because I did not go to the scene to observe, it is difficult to determine which of the reasons is caused. I cannot assert here, please forgive me.
