How exactly does the real stone paint construction process work?

When it comes to the construction process of real stone paint, many friends may not be familiar with, or even have not heard of. In fact, this process mainly refers to the wall painting process, and specifically, mainly these steps, that is, substrate treatment, primer construction, spraying with color paint, stone paint construction, and finally the masking paint spraying, basically as long as the completion of these specific parts, stone paint construction process will be able to be accomplished. So, how to operate these steps? Here we come together to learn.

1. Base surface treatment.

Before the base surface treatment, the wall needs a certain amount of time for maintenance. Before scraping putty, the loose, skinned, hollowed and chalked grass-roots level should be thoroughly removed, and then dust, oil and other pollutants should be removed. Repair the wall with exterior putty, the first partial leveling, fill large holes and gaps with putty or fill逢胶, wait for the putty to dry, partial sanding, and then full batch of putty to make the grassroots level. After the putty is completely dry, sand to make the grass-roots leveling. Because the real stone paint has a certain thickness, the level of grass-roots requirements are not as high as the thin flat coating.

2. Paint closed primer.

After the putty is dry, paint a closed primer. Closed primer generally do not need to add another diluent to dilute. Its purpose is to clean up the grass-roots level, increase the strength of the grass-roots level and the adhesive strength of the coating film. Generally used roller coating construction, can also be sprayed construction.

3. Spray solid color primer.

The purpose of spraying color primer is to make the color of the substrate consistent. Can effectively avoid the real stone paint coating film through the bottom of the phenomenon caused by the hair flower, but also can reduce the amount of real stone paint to achieve uniform color and good decorative effect. Substrate coloring treatment materials mainly with adhesion, durability, water resistance of good external thin coating latex paint. According to the color of the identified natural stone or the color of the sample for color mixing ingredients, as far as possible to make the color of the paint close to the color of the real stone paint itself. The paint must be painted evenly, there must be no leakage of paint, through the bottom part, generally painted twice. In order to achieve the decorative effect of imitation stone, but also to facilitate the construction operation, can be divided into compartments of the real stone paint coating spray, and in the compartment on the coloring coating of the grass-roots level of the selection of coating, in the large surface spraying on the compartment should be completely blocked or scraping parts of the treatment.

4. Spraying real stone paint.

Real stone paint generally do not need to add water, if necessary, a small amount of water can be adjusted, but the spraying should pay attention to the control of the product construction viscosity is consistent, the air pressure, the size of the nozzle, the distance should be strictly consistent. In case of windy weather, construction should be stopped. The construction of real stone paint is difficult, if the control is not good, the coating film is easy to produce local phenomenon of blossom. Therefore, when spraying real stone paint, pay attention to the gun and the gun should not be sprayed on the wall to complete; and the speed of the gun to move evenly; each spraying amplitude of the edge, to be in front of the amplitude of the edge of the spraying has been good to repeat the 1/3, and the width of the overlap should be consistent; to keep the film thin and thick uniform. The key to the construction of real stone paint in the consistency of the paint to be appropriate, the first spraying slightly thinner paint, to be uniform, dry and then spray the second coat. When spraying the second coat, the paint is slightly thicker and sprayed thicker. When the spray hopper material after spraying, with the airflow will spray a good finish blowing again, so that the ripple pattern closer to the stone effect. If you want to achieve the marble pattern decorative effect, you can use a double nozzle spray bucket construction, sprayed at the same time the two colors, or a single nozzle spray bucket were sprayed in two colors, to achieve the color overlap, seemingly hidden decorative effect.

5. Spray varnish.

In order to protect the finish, increase the gloss, improve pollution resistance, enhance the overall decorative effect, in the paint spraying is completed, masking treatment, spraying masking varnish. To be completely dry after the real stone paint (generally sunny days at least 3 days), before spraying varnish, construction can be added to the appropriate amount of thinner, pay attention to keep the viscosity, air pressure, nozzle size consistent, pay attention to prevent the phenomenon of hanging.

After reading the contents of the above introduction about the construction process of real stone paint, I believe we are very clear about this process, right? In this process, we need to pay attention to is our operation must be more standardized, and it is best to ensure that the substrate can be flat, careful operation to avoid cracks. In fact, this process is relatively speaking, may be more complex, many friends will find it more difficult, but, as long as we remain patient, using the correct method can be, I believe that can be successfully done.
