The putty knife is usually used to cut and scrape all kinds of putty, and very few people use it for other purposes in daily life, such as our roadside stall vendors used to shovel food, etc., of course, the use is the interior decoration, but many friends do not know what the role of the putty knife is.
1. The paint is peeling, the surface is too smooth, and the newly coated paint cannot stick to the surface, which may be that the wood is rotten, the metal is rusty, and the paint quality is poor and peeling. When you apply paint, primer, or paint, you use a putty knife.
2. The paint is flowing. If the paint is too thick at once, it will cause flow. When the paint is not dry, brush the paint with a gray knife, if the paint has started to dry, then wait for it to dry, use fine sandpaper to smooth the paint surface, brush it clean, then wipe it with a damp cloth before applying the paint.
3. After the paint is blistered, first use a putty knife to puncture the foam, after the water comes out, it means that there is moisture under and behind the paint layer, use a hot air spray gun to remove the blistered paint, so that the wood is naturally dried and then apply primer to paint on the entire repair surface.
4. If the fracture area is not large, you can use sand blocks or dry and wet sandpaper to water the damaged paint, wear and tear the damaged paint, after the surface is smooth and grinding, put the putty knife on the putty, brush the paint, and then coat.
