1, the foundation of the wall should be prepared, the wall skin should be scooped up to expose the brick layer, and the bricklayer should be asked to mix the cement and sand evenly in proportion to prepare the foundation.

Make the brushed wall smooth. So that the cement and sand base will not run out of oil.

2. After drying, apply talcum powder, lithopone powder and putty powder on the brushed surface in proportion, conduct the second layer, and treat it thinly layer by layer.

3. After thoroughly drying, carefully polish it with sandpaper. The effect is that the wall is smooth and even feels like human skin. Scraped putty powder should be mixed with good latex and 80 1 glue, otherwise the fastness will affect the picture. After the basic work is completed, you can paint with oil paints to your heart's content. This work is very hard and requires high technology.

4. After painting, when the oil painting is dry for half a year, it should be covered and sprayed from polyester paint, preferably imported from Germany, with the same effect as a mirror. Even if the dust falls in the future, wiping it with a rag will not affect the picture. For reference.

If you don't want to go to so much trouble, make a wooden frame on the wall with wood and stretch the whole wall with canvas, so it will be much easier to do it on canvas. The biggest advantage is that oil paintings can be taken away, just like the landscape wall, which is very enjoyable. I've done this before. Not spectacular, very imposing, very beautiful.
