Water bag colorful coating construction should pay attention to what issues?

More and more nowadays, exterior wall coating, water bag water coating arises at the historic moment. The technology development of modified resin and stability good pigment is made. This is a one-time spraying water full color granite coating. The color is more vivid and durable. Water bag color stone paint colorful. It can provide the required special color and has a very high emulsification. Secondly, this paper introduces the water bag colorful coating construction of some of the problems should be paid attention to. 1. Grassroots use special putty, the best is gray putty mortar, do not recommend using white putty. Gray putty is mainly composed of gray Portland cement and acrylic polymer, has a good adhesion, filling performance ( Little shrinkage) , crack resistance and workability, have a certain strength and hardness, the drying time is moderate, The surface dry and hard work) , easy to scratch and polishing. In many upscale community water package during the construction of the colorful coating, gray putty mortar obviously more advantages than white putty. Putty polishing is a key link. Polishing putty can during the day in a special sand box done bit by bit. After polishing, metope will remain flat. In the evening, the metope of oblique sunlight can observe segmentation. If it is found that the uneven place, can continue to polish. If the grinding is not good, use marker pen marks, use putty repair, dry again after polishing, require each flatness to level off. Spraying and maintenance will need about 24 hours to the next construction. 2. Water bag need to put on colorful coating colour sand really stone paint, then sprayed multi-color, sensory effect is obvious, but the texture or color sand really stone paint more or less will be exposed. These two kinds of material is mainly composed of gravel, uneven surface, the product surface have innumerable the pore. Due to the air back to glue phenomenon, dust and dirt will stick on the wall, cause local pollution. Of course, under the aegis of the surface oil, the rains washed out can restore the original appearance. Special elastic intermediate coating is used to increase the thickness of the coating, used for waterproof and crack resistance of metope, The main purpose of this procedure is to increase the thickness of the coating, to increase the crack resistance, water proofing property, and the main color reflective) 。 3. When using neoprene alkali resistant seal primer, must be in place, don't leave out dead Angle, especially the side of the door hole, line and waist line is an internal Angle ( During the color jump) 。 Otherwise, when spraying main ingredient, protective film was torn off or masking paper is torn off, this part of the water bag color coating is easy to stick side, causing the flannelette. 5. When metope need because of the uneven construction repair to repair the same work area at the same time, such as several square or a facade, repair and see the flowers, because flowers may be more and more. In construction of water bag colorful coating, please pay attention to the weather forecast. Spraying multicolor coating, only after the first drying can spray for the second time. General interval for 12 hours. After spraying multicolor paint, for at least 24 hours after can cover surface. At the same time, pay attention to ensure the construction within one week after the rain and heavy rain. 6. Do not force stirring water bag colorful coating, water don't, don't be mixed with other substances, as far as possible on the colorful coating after use. Making plane water bag multicolor coating, surface texture coating, really stone paint color sand back or elastic medium coating back more smooth, so the multicolor coating for the first time, the gun should be moving faster, in order to prevent sagging. 7. Water bag must have a new colorful coating and a better finish. No paint color paint film is not dense, anti-aging, weather resistance, resistance to pulverization and color preserving effect will be greatly reduced. In order to cover during the period of construction of uneven thickness, it is recommended to use matte varnish. In addition, in order to avoid the frosting phenomenon caused by roller, suggest building european-style components coating finish. 8. Eaves Angle should be paid attention to the construction of Yin and Yang. Yang Angle should be covered in the spraying department. Don't be afraid of the material
