Crack Paint Note: Share the spray and construction techniques of crack paint

 
Many people have begun to know and use crack paint, but they have not mastered the method. How to make the paint consumption not waste and crack evenly, share and discuss together below.
 
 
1: First, spray the primer on the workpiece in advance,
 
Crack paint: cracked paint water [solvent] open at a ratio of 1:0.8 specified by the supplier and stir well, filter,
 
Spray the dry sprayed primer on the workpiece. When spraying, the gun will be even and stable. Do not spray the spray separately. Otherwise, the crack paint effect will vary depending on the thickness of the paint film. After baking for 65 minutes after 65 degrees. .
 
 
The crack effect can be generated by the shrinkage action of the cracking agent, and the color of the base paint is exposed under the crack effect. If the crack lacquer is coordinated with the primer, a good pattern and color can be obtained. When the cracked topcoat is sprayed, it must be applied after the primer is dried, otherwise the crack will be affected. Crack cracking is a matte effect, and the resistance is generally not good. Finally, use semi-matt, matte clear topcoat or two-component PU varnish\uv varnish\plastic varnish\self-drying paint in crack Paint surface finish. Before the large-area construction, the sample must be sprayed on the small sample plate of the sprayed primer. According to the effect of the crack size, select the construction viscosity of the crack top coat, the thickness of the paint film, and adjust the shape, air pressure and paint amount of the spray gun. (Fixed).
 
Precautions:
 
The construction of cracked paint requires certain skills. The size of the crack, the uniformity and the viscosity of the paint, the amount of gas sprayed, the amount of oil, and the thickness are all related. The paint viscosity of the paint with the same crack effect should be uniform, and the color ratio of the paint with the same crack effect should be uniform. The air pressure of the air compressor should be consistent when spraying, and should not be large or small. The diameter of the spray gun is 1.5; 2.0mm, and the oil outlet should be smooth. The speed and distance of the gun should be consistent, and the amount of exhaust and oil should be well controlled.
