1. Spray small cracks with latex paint of the same color or cover them with pigments
If the cracks of the plaster are not large, or there are only some unremovable stains attached to the conspicuous place on the surface, then we can use the same color pigment or latex paint to spray it, so that the cracks can be covered.
2. If there is a large crack but no damage, you can choose to repair it
If the plaster has a large crack, but the plaster is not damaged, and the place where the crack occurs is not on the ceiling or other places that are prone to fall and affect safety, we can take a knife and cut a V along the cracked place. Then use gypsum powder and glue to repair the incision, or you can directly use special gypsum repair glue. After you fill it up, be sure to clean up the excess glue around in time, and then use a hair dryer to dry it. This kind of plaster is not only strong and durable, but also can't see that it has been repaired at all.
3. Cracks appear in key parts, and the plaster should be replaced decisively
If there is a crack in the upper space of the wardrobe or the plaster of the roof, then no matter the size of the crack, it must be replaced decisively. Because once there are cracks in the appearance of these areas, the paste inside cannot be guaranteed, and there may even be large gaps inside. If it falls under the influence of its own gravity, it will induce a safety accident.
