Why are some Stone Garden Statues products prone to paint peeling?

I believe everyone is familiar with Stone Garden Statuess. They play a pivotal role in the aesthetic construction of the city, but we also see many surface paints peeling off outdoors, and even some surfaces are rusty. The overall look is particularly old.

Let's discuss the reasons why the paint of Stone Garden Statuess falls off. First of all, there is a layer of wax on the surface of the stone statue model sculpture that has just been made. In order to make the Stone Garden Statues paint easier to paint, the wax on the surface needs to be polished off, and the surface is polished with sandpaper until the product does not reflect light. Secondly, fill up the unevenness or potholes on the surface of the sculpture with putty, and polish it. Repeat this several times to treat the surface of the product well. Only when the bottom is prepared can it have better adhesion and leveling when spraying paint later.
1. When only spraying Stone Garden Statues paint, the environment should not be too humid. Try to postpone the construction in rainy weather. If the moisture contained in the base of the sculpture is too high, the moisture in the paint layer will diffuse outwards and the paint film will bulge, thus making the surface of paint falling off.
2. When processing the surface of the product, wait until it is completely in time to start spraying the primer and topcoat, and leave the flash-drying time of the previous gun for the next spraying.
3. If the primer and topcoat of the Stone Garden Statues paint used are the same matching product, the chemical reaction of the unmatched product will also cause the paint to fall off during use.
4. Outdoor model Stone Garden Statuess should also pay attention to maintenance. If the products are in flowerbeds and grass, you can add a cushion on the ground to prevent direct contact with the ground to reduce the growth of water vapor, and it is not suitable to move frequently.
5. When exposed to the sun, properly spray some water on the surface to keep the surface temperature from being too high, so as to prevent hollowing.
