In the field of exterior wall decoration, imitation stone coating It is very popular Lacquer It is also the favorite of exterior wall decoration. Because of its energy-saving and environmental protection, lifelike stone imitation effect and relative cost Marble Cheap features have captured the favor of many consumers. However, no matter how good the product is, "three materials, seven construction", only perfect construction can show the superiority of the product. The following is a brief introduction to the precautions of stone like paint in construction.
one If necessary, please select a professional stone like paint construction team.
two Due to the heavy weight and large amount of stone like paint, large packaging specifications are commonly used（ 75KG/ Barrels), sedimentation may occur during long-distance transportation or when the storage time is too long. Before opening the barrel, the whole barrel shall be filled upside down and stirred evenly. The construction viscosity has been adjusted before leaving the factory. It is not recommended to add water to dilute the viscosity.
three Recommended hanging basket Spraying real stone paint will leave scaffold Connector It cannot be seen without dismantling the scaffold, which is obvious after dismantling.
four Temperature: usually five º c above thirty-five º c Construction under the following temperature conditions; Humidity: the air humidity suitable for construction is 60%--70% ， 85% No construction is allowed in rainy days; Ensure that after spraying twenty-four No rain inside; Wind force greater than four Stone like paint shall not be sprayed above Grade II.
five Air pressure of air compressor shall reach 8kg As mentioned above, the actual amount of coating will vary depending on the roughness of the base surface or different construction processes. Before construction, the coating rate shall be tested according to the site conditions.
six As for the sand loss during spraying: no matter any spraying, there will be loss. The sand loss during spraying should be judged according to the viscosity of construction products, construction air pressure, construction personnel's methods, etc. It is recommended that the coating rate be tested before the commencement of the project.
seven . About the phenomenon of spray paint blooming: stone like paint blooming is more common, which is caused by uneven spraying, especially on dark paint. The color of the thick sprayed area is inconsistent with that of the thin sprayed area. It is recommended to spray thin paint for many times , Multiple molding can avoid blooming.
eight Color difference: since stone like paint is basically made of natural colored sand, there will be slight color difference between batches, which is normal. It is recommended that the same batch of materials be used on the same wall by the same batch of people during construction. The whole wall should be built from top to bottom in one go to avoid new and old colors caused by intermittent construction. The plane effect and the rough effect will produce sensory differences. Pay attention to the color differences of some colors under the conditions of backlight and positive light, direct sunlight and refraction. Repair of color difference: after the construction of a wall, try to leave several barrels of products of the same batch to repair the defective wall in the final stage of the project to avoid color difference caused by the final repair.
nine , Whitening: Whitening Yes two One is the phenomenon of alkali returning on the concrete wall, and white powder will appear when you touch it with your fingers. Second, there is no such phenomenon when the roll coating of the finish coat is not applied. After the roll coating, it turns white, as if fog is falling on it. This is because the surface of the stone like paint is rough and uneven, and the roll coating of the finish coat is not evenly applied, resulting in the accumulation of the finish coat in the groove.
