Now that people want to have a better decoration effect on the decoration, then let's understand the crack paint . Now the crack paint to be introduced to you by Xiaobian is a new decoration paint, which is not only useful but also has a crack. How to use the paint, we also introduced to us the detailed steps of the construction of the crack paint floor. I hope that we can learn more about the crack paint after reading it.

First, the advantages of crack paint

1. Crack paint is made of nitrocellulose, pigments, extender pigments, organic solvents, adjuvants, etc. It can form nitro crack cracks of various colors. It is also such that crack paint also has some fundamentals of nitrocellulose lacquer. Characteristics, it is a volatile self-drying paint, no need to add curing agent, and the drying speed is fast.

2. Therefore, the cracked paint must be in the form of one or more layers of nitrocellulose varnish of the same characteristics to fully fuse and exhibit another crack characteristic of the cracked paint. Due to the high content of crack paint powder and the high volatility of the solvent, it has large shrinkage, low flexibility, high tensile strength after spraying, and forms an outstanding and uniform crack picture, which enhances the appearance of the coating. , progress and decoration.

3. Crack paint is an art paint with special decoration effect. After the painting, a beautiful crack picture can be formed, the crack of the crack paint is impermanent, the patchwork is accurate, and the artistic three-dimensional beauty is obtained. Crack paint is commonly used in toys, crafts, building decoration and home decoration, especially for antique simulation decoration.

Second, crack paint construction method

1. The crack paint is a one-component paint. It is not necessary to use other curing agents when the paint is applied. The construction viscosity can be adjusted with a suitable amount of special cracked water produced by the same factory for construction. After the well-conditioned cracked paint is thoroughly mixed, it can be applied by filtering with a 100-200 mesh filter. The paint is now ready for use. Once prepared, do not use it within 2 hours for more than 4 hours. After the paint is opened, it must be sealed immediately to avoid evaporation, moisture absorption and tampering, which will affect the application.

2. The construction crack paint is generally better in spraying construction, and the crack pattern is round and natural and uniform. If the brush is applied, the crack will be affected by the gesture and uneven direction of the paint, and the crack pattern will be uneven and rough. a feeling of. Before the construction crack cracking, the primer should be applied first. The primer can be used with the matching crack primer produced by the same factory. It can also use the aluminum powder, pearl powder, gold powder and other colored primer. Generally, the color contrast between the primer and the topcoat. The larger the stereoscopic effect, the better the effect.

Third, crack paint precautions

1. Pay attention to the temperature and humidity of the construction environment during construction. The humidity should not be too large. The temperature is about 25 degrees Celsius, and the paint film is dry faster and more complete.

2, crack paint needs to use the spraying process, must be kept even when spraying, the film thickness remains the same. The thickness of the primer must not be too thin, otherwise the strength is too low. If the paint film of the topcoat is too thick, the crack attack speed will be slow, and the cracked texture will be too large; while the topcoat paint film is too thin, the crack speed will be too fast, and the texture is very fine.

3, the polishing process of the primer, and the process of painting the cover, are to increase the durability of the cracked paint, or because the paint surface is dry and shrink, it is easy to form the paint surface to fall. Therefore, it is necessary to do the details in the construction to avoid the situation of rework.
