With the development of the construction industry, a variety of new building materials have come into being, among which real stone paint, as a coating with high degree, strong decoration and good weather resistance, has received extensive attention and application. Real stone paint can not only imitate the texture and color of various stones, but also effectively protect the building and extend its service life. So, how to carry out the construction of spraying real stone paint?This article will give you a detailed introduction to the construction method of spraying real stone paint.
1. Preparation before construction.
1.Grassroots treatment: First of all, the base layer of the building should be treated to ensure that the base layer is clean, smooth, free of oil stains, floating dust and other debris. For cracks, uneven places, it is necessary to repair and level.
2.Primer coating: After the base treatment is completed, a special primer needs to be applied to enhance the adhesion between the real stone paint and the base layer and improve the durability of the coating. The primer should be evenly painted, and there should be no omission, sagging, etc.
3.Shielding and protection: Before construction, the surrounding environment should be shielded and protected to prevent the real stone paint from splashing on other parts and affecting the appearance. At the same time, doors, windows, pipelines and other facilities should also be protected to avoid pollution.
Second, the construction method of spraying real stone paint.
1.Preparation of spraying equipment: Choose the appropriate spraying equipment, such as air compressor, spray gun, etc., and check whether the equipment is operating normally to ensure the spraying effect.
2.Real stone paint stirring: Pour the real stone paint into the mixer, add an appropriate amount of water and stir until the real stone paint is fully stirred and there is no granular matter. When stirring, attention should be paid to controlling the stirring speed to avoid splashing real stone paint.
3.Spraying operation: pour the stirred real stone paint into the spray gun, adjust the pressure and discharge amount of the spray gun, and then spray evenly from top to bottom and from left to right. When spraying, a certain distance should be kept to avoid excessive accumulation of real stone paint, which will affect the thickness and texture of the coating.
4.Spraying skills: In the spraying process, the speed and distance of spraying should be mastered according to the characteristics and design requirements of the building, so that the real stone paint presents a rich sense of hierarchy and three-dimensionality. At the same time, attention should also be paid to the direction of spraying to avoid missing spraying, repeated spraying and other phenomena.
5.Spraying seam treatment: During the spraying process, the appearance of seams should be avoided as much as possible. If seams are unavoidable, multiple sprays should be applied to the seams so that the real stone paint at the seams will naturally transition from the surrounding coating without affecting the overall effect.
6.Finishing the spraying: After the spraying is completed, the spray gun and the surrounding stains should be cleaned in time to ensure that the construction site is clean and tidy. At the same time, the thickness and texture of the coating should also be checked, and if there are deficiencies, they should be repaired in time.
3. Maintenance work after construction.
1.Coating curing: After the construction of real stone paint is completed, it should be cured for a certain period of time to ensure the hardness and weather resistance of the coating. During curing, direct sunlight and rain should be avoided so as not to affect the quality of the coating.
2.Cleaning work: After the construction is completed, the garbage and stains on the construction site should be cleaned up in time to keep the environment clean and tidy.
Fourth, precautions in construction.
1.The ratio of real stone paint: when stirring the real stone paint, it must be proportioned according to the proportion provided by the manufacturer, and do not increase or decrease the proportion of water and real stone paint at will, otherwise it will affect the quality and effect of the coating.
2.Spraying distance and speed: Maintain the appropriate distance and speed when spraying, too close will cause real stone paint to build, too far away will make the coating uneven. At the same time, the spraying speed should be moderate, too fast may lead to uneven coating thickness, too slow may affect the application efficiency.
3.Spraying coating: In order to achieve a better three-dimensional effect, the real stone paint should be sprayed multiple times, and after each spraying, it is necessary to wait for the previous coating to dry before the next spraying.
4.Temperature and humidity: Attention should be paid to the temperature and humidity of the environment during construction, and it is best to carry out construction when the temperature is moderate and the humidity is low to ensure the drying and curing effect of the coating.
5. Common problems and solutions.
1.Coating cracking: If the coating cracks, it may be caused by improper treatment of the base layer or an inappropriate ratio of real stone paint. The solution is to re-apply the base treatment and ensure that the ratio of real stone paint is correct.
2.Coating peeling: If the coating is peeling off, it may be caused by uneven primer application or insufficient adhesion of the real stone paint to the substrate. The solution is to reapply the primer and ensure the adhesion of the real stone paint to the base layer.
3.Uneven coating color: If the coating color is uneven, it may be caused by uneven spraying or uneven mixing of real stone paint. The solution is to adjust the spraying method and the mixing method of the real stone paint.
Although the construction method of spraying real stone paint is relatively complex, as long as you master the construction skills and precautions, you can ensure the quality and effect of the coating. During the construction process, the operation should be carried out in strict accordance with the construction steps, and the state of the coating should be paid attention to at any time, and if there are deficiencies, it should be adjusted and repaired in time. Only in this way can the real stone paint exert its maximum decorative effect and protective effect.
