Paint knowledge: how to solve the problem of art paint color whitening in rainy season

Core tip: as a new type of exterior wall paint with excellent performance, it pays attention to the construction requirements According to different texture varieties, quality and coating base, construction personnel will make corresponding texture paint construction plan However, if affected by rainy season weather, the construction personnel may not grasp it very well sometimes, which may also lead to the phenomenon that the color of artistic coating texture paint turns white In view of this situation, we can analyze the following aspects: 1 Construction temperature at the construction site: for example, the local construction temperature is too low to close to 0 ℃, after the construction of materials, when the paint film is not dry, there will be rainy weather again, in this case, the surface color of the wall will be washed after the rain washing Paint knowledge how about Akzo Nobel Powder Coating Recommended introduction: powder coating is a kind of coating with different form from general coating, which is in powder form It is a new type of coating, because of its own advantages and more and more known by people Let's introduce Akzo Nobel Powder coating Akzo Nobel Powder coating is a cost-effective coating solution, which can be applied to different kinds of products After the treatment of static electricity and fire baking, a tough and durable coating surface will be formed, with the least impact on the environment Since the introduction of this technology, powder coating has been able to continue to maintain the Home of coatings news: as a new type of exterior wall paint with excellent performance, there is a certain stress on the construction requirements According to different texture varieties, quality and coating base, construction personnel will make corresponding texture paint construction plan However, if affected by rainy season weather, the construction personnel may not grasp it very well sometimes, which may also lead to the phenomenon that the color of artistic coating texture paint turns white In view of this situation, we can analyze it through the following aspects: 1、 Construction temperature on site: if the local construction temperature is too low close to 0 ℃, and the paint film is not dry completely after the material construction, there will be rainy weather again In this case, the surface color of the wall will be washed away by rainwater, and the serious wall paint film has completely fallen off, so the color will appear light and white 2 Improper construction: in the process of construction, some people often spray with spray gun, mix too much water, or omit to paint There is uneven painting of the top coat In addition, in wet rainy season, the wall surface absorbs uneven water The wall surface with more water absorption is affected by water and dust in the atmosphere, resulting in inconsistent wall color 3 In order to reduce costs and cut down on materials, the construction company does not apply putty before making artistic coating texture paint, but directly applies artistic texture paint on anti crack mortar There may be excessive alkalinity on the wall surface, which will be washed by rainy season after the construction of texture paint After long-term water absorption, the wall surface will also appear alkaline phenomenon In the face of the above situations, the solutions are as follows: 1 In rainy season, if construction can be avoided, construction shall not be carried out until good weather 2, if the problem has occurred, the art coating paint has been used on the wall, and the roller coating can be used to make the wall color consistent 3 The construction company shall pay attention to the control of the mixing rate of latex 4 During roll coating, it is necessary to keep the paint film even and flat, and it is not allowed to spray the top coat again Art coating texture paint is widely used on the exterior wall, and some problems will occur due to the influence of the weather and the technology of the constructor in the construction The problems shall be fed back to the paint manufacturer in time to work out the best solution, so as to avoid delaying the construction progress and painting effect Home of coatings is specialized in coatings, diatom mud, paint coating, coating technology, fire retardant coating news and coating, diatom mud, paint coating, coating technology, fire retardant coating decoration knowledge and decoration renderings,
