Spring is the transition season between winter and summer
Q1 What are the precautions for using imitation stone paint on exterior walls in spring?

Q2 When applying imitation stone paint for exterior walls, should the top oil be "rolled" or "sprayed"?
First of all, let's understand the coating construction method, the effect after "rolling" and "spraying": the roller coating film is relatively thick, and the tactile feeling formed by spraying is relatively good
It is recommended to use the roller coating method for the application of the face oil
Of course, whether the face oil is rolled or sprayed, two constructions are required
At present, there is a more stable surface oil construction method on the market: that is, two people cooperate with the construction, one person sprays the material, and one person performs the roller finishing
Q3 Is it better to spray the rough stone-like paint (sand in water) to break the particles, or is it better to spray out particles the size of soybeans?
At present, the market requirement of the stone-like paint (sand-in-water) for the burnt surface is that the final decorative effect needs to have grain points
.
If the particles are broken, the final result will be that the color of the particles is blurred and broken, and the texture is flat, which is not the traditional fire-faced stone-like paint (sand in water)
.
At present, the spraying methods of more rough stone-like paint (sand-in-water) on the market are as follows: the first intermediate coat is constructed by adjusting the atmospheric pressure to form the basic color, and the second intermediate coat is constructed by reducing the air pressure, granulating, and spraying
.
The texture and graininess of the entire color finally formed are relatively good, which is one of the more current spraying methods
.
This construction method can not only affect the spraying effect but also improve the coating rate of the middle coat
.
If the particle points are broken, the final effect is not the sand-in-water effect that the public wants
.
Q4 What are the requirements for the air pump and air pipe?
Both the air pump and the air pipe are necessary tools in the spraying operation
.
Regarding the air pump, we need to determine the site conditions first to determine the electricity consumption mode (two-phase or three-phase)
.
a.
When the electricity is used for three-phase electricity, the requirements for the air pump will not be too high
.
Three-phase electricity basically has a motor of more than 3500W to provide power, which can basically meet the needs of two spray guns for simultaneous construction
.
b.
If there is no three-phase electricity, we can also operate in two ways: one is the air pump with two-phase electricity, the power configuration is at least 2200W or more, which can only meet the construction of one spray gun, and the oil-free silent air pump is not recommended.
It is used in the construction of the outer wall; the second is the diesel air pump, but the diesel air pump must be transported by vehicles at any time before it can be used;
Regarding the trachea, it is required that the diameter of the trachea should not be too small, otherwise the air volume required by the overall spraying will not be enough
.
On the market, more trachea with a diameter of 1.
2cm are used, and the wall thickness of the trachea cannot be low, especially in summer, it is easy to burst
.
The length should not be too long, and it is generally recommended to control it at about 50m
.
Usually self-built villas are basically 3~4.
5 floors, and the demand does not exceed 20m
.
So no matter how we pull, 50m of air pipe is enough for the job
.
Too long air tubes will result in substandard spray air flow requirements
