It is most convenient to spray paint if you have basic skills. You can also use mixed spray paint, spray paint on a large area, and spray paint on a small area if you feel that the spray paint is out of control. But wait until it dries.
If you want to keep it, don't draw advertisements, it will melt in the water. Acrylic pigment is insoluble in water after drying, and can be used to paint on almost all materials such as metal, wood, stone, cloth and leather. Very suitable for graffiti. You can also doodle on clothes or shoes with acrylic paint.
There are also oily markers, which can be used to sign or make details.
It's hard to say how much paint it takes to paint a wall. It depends on how big your wall is, whether you make the paint thinner or thicker.
But it can be used as a reference. Generally, a bottle of advertising paint is about 0.5 square meters (the water consumption is just enough to mix the paint, and the whole pen will not stick).
If it is spray painting, the standard 400 ml can can be sprayed out to cover about 2 square meters.
The price of acrylic pigment is similar to that of poster color, ranging from painting a 400 ml can of 5-20 yuan. You have to consider the cost yourself.
As for how long it takes to draw a wall, it depends on your basic skills, what to draw, how big it is, how high the quality requirements are, and so on. Personally, I think it is about 8 square meters (4x2), ranging from 2 to 6 hours. If it is painted with acrylic paint as fine as this, it is not surprising to paint it for two days and two nights.
There are many matters needing attention, and the following points are mentioned:
1, and most importantly, don't scribble. If you are caught painting in the street, you will be fined, ranging from 100 to 10000 yuan, and you have to clean it yourself. Be sure to pay attention to this one. Also protect our city clean and tidy.
2. As the guy above said, take protective measures. Spray paint and acrylic paint are toxic, of course, graffiti with more serious spray paint must find a ventilated place.
It is recommended that you wear a gas mask at all times when painting. The sprayed oil mist and gas are easily inhaled, which is very irritating and toxic to human mucosa and lungs. If you don't wear a mask, spray a small half bottle and you will feel uncomfortable in the next few days. In severe cases, you may have a dry cough and chest tightness. If you don't have a gas mask, you can also use a mask, preferably with water.
Wear a mask if you use acrylic paint.
In addition, it is best to cover the exposed parts of the body, because paint and acrylic paint are not easy to clean when they contact the skin, and they are irritating and toxic.
The best way: wear a raincoat and a mask. Ha ha.
Give two suggestions:
1. It is best to choose a good venue and take your own cloth paintings. Hang up the canvas in the suburbs and start. You can also look for unfinished buildings, damaged factories, or temporary external walls on the site. Of course, make sure it's safe.
2. As far as graffiti is concerned, make a sketch first, draw it out and then decide which one to draw first and which one is the background color.
Finally, don't let graffiti become urban garbage.
