It costs thousands of dollars to learn wall painting. I can tell you how to make it by hand. Hand-drawing is to draw a border with a pencil and then color it. Drawing a border requires a good artistic foundation. It's really hard not to learn, but I can teach you three ways to make wall paintings without art foundation.

1, hand-painted, what if you can't draw? Just buy some acrylic and brushes, and then buy a projector. Use the projector to project the pattern to be made on the wall, and then draw it according to the pattern projected by the projector, and you can make some patterns that are not very complicated. Of course, complex gradient 3D renderings can't be made.

2. Printing wall paintings with screen printing technology means making the painting to be done into a screen template and printing the painting on the wall with the principle of screen printing. This kind of template can be made in the place where screen printing equipment is made, but the cost of template is relatively high, and it is not suitable if the pattern cannot be reused.

3. Making a wall painting with carving technology means carving the pattern to be made on the adhesive with a carving machine, then sticking it on the wall, deducting the carved part and coloring it with propylene or diatom mud pigment, so that a painting can be made, and the cost is low and the pattern selection is many. This technology is very common in diatom mud industry now.
