Can copper paint cover the gap?

No, you need to fill in the hole first.

1. Before filling the hole, do a good job of protection, such as covering the surrounding ground, preventing falling dust or paint from damaging the ground, and covering the furniture and household appliances next to it with cloth. 2. It is necessary to remove the sundries beside the hole to make the hole relatively flat. 3. Stir the putty. We can paint the holes in the wall with putty powder. If the hole in the wall is large, in order to prevent putty powder from pouring into the hole, grid tape can be used to stick the hole first, and grid tape also has a certain curing effect to prevent the hole from expanding again and appearing some cracks. 4. Then blow the putty, and then blow it for the second or third time after drying. The drying time is different, sometimes it is tens of minutes, sometimes it may be an hour. After the putty powder is completely dried, it should be polished, and then scraped for the second time to repair the wall. 5. Finally, apply latex paint or paint, and wait until the first 1 pass is dry before brushing the second time. 1. If the hole is small, we can repair it with gypsum powder. The effect after repair is basically the same as that of the original wall, and it can be seamless. Some people recommend toothpaste, but the hole in the wall is relatively small. You can choose white toothpaste to fill some small eyes and then smooth the surface. There is also a white sealant on the market. If it is some nail holes, it can be directly coated with sealant and then scraped flat, and the effect is also very good. 4, you can cover the hole with some small ornaments, which can also play a decorative role.
