If the polyurethane anticorrosive paint peels off during construction, the surface of the coating may not be smooth.
If the original polyurethane anticorrosive paint is glossy or powdery, the new polyurethane anticorrosive will not stick well on its surface. Or it may be the decay of the wood or rust on the metal, or it may be peeled off because of the poor quality of the paint.
If the polyurethane anticorrosive paint is peeled off in a small area, you can sand it with fine sandpaper first, then put on putty, brush with primer, and repaint it. If it is a large area of peeling, all polyurethane anticorrosive paint must be scraped off and repainted. If the polyurethane anticorrosive paint cracks, it is most likely to use a chemical paint remover or a hot air spray gun to remove the paint and then repaint it. If the extent of the fracture is not large, you can use a sanding block or wet and dry sandpaper to soak the water to remove the broken paint. After the surface is smoothed, put putty, brush on the primer, and then repaint.
