Coating knowledge: five characteristics of qualified stone paint base

Core tip: the construction of real stone paint is composed of different coating systems The quality of the system directly determines the quality and service life of real stone paint in the actual construction The coating system is divided into four parts: base layer, sub coating, main coating and surface coating As the basis of the whole coating system, the maintenance of base layer is very important Qualified base layer needs to meet the following five characteristics: firm The qualified base course must reach a certain degree of firmness The hollowing, layer lifting, cracking and peeling of the wall will affect the construction When judging whether the base course is firm or not, various detection methods such as knocking, visual inspection and scraping can be combined to ensure that the base course is firm and meets the construction standards 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 Paint Home News: the construction of real stone paint is composed of different coating systems, the quality of the system directly determines the quality and service life of real stone paint, in the actual construction The coating system is divided into four parts: base layer, sub coating, main coating and surface coating As the basis of the whole coating system, the maintenance of base layer is very important Qualified base layer needs to meet the following five characteristics: firm The qualified base course must reach a certain degree of firmness The hollowing, layer lifting, cracking and peeling of the wall will affect the construction When judging whether the base course is firm, various detection methods such as knocking, visual inspection and scraping can be combined to ensure that the base course is firm and meets the construction standards Smooth Leveling is an important step to ensure the decorative effect of paint Uneven base will affect the final decorative effect of paint, such as blooming If the flatness of the base course is poor, it will also increase the workload and material consumption of filling and finishing Attention should be paid to the details: the internal and external corners are vertical, square and vertical Dry From the technical point of view, the moisture content of the base course should be less than 10%, which can be tested by professional instruments If the moisture content of the base course is too high, it will cause the coating to pan alkali and slow film-forming, and it is easy to produce the phenomenon of sagging and bulging The suggestions for morninguang coating are as follows: generally for cement For mortar, under the condition of good ventilation, the moisture content of mortar can meet the requirements only after 14 days in summer and 28 days in winter It is not allowed to neglect the base maintenance in order to catch up with the construction period Neutral: generally, the cement mortar under construction has a strong alkaline, and the excessive alkaline of the base course will cause the coating to be alkaline and discolored, and even affect the adhesion of the coating Therefore, in order to prevent the phenomenon of alkali flashing, the pH value of the base course should tend to neutral, generally speaking, pH < 9 Clean The clean surface of the base course is conducive to increasing the adhesion of the coating and ensuring the construction quality Therefore, before the construction, the rust, sundries, grease, silica gel, film remover, etc on the surface of the base course should be cleaned to ensure the cleanness of the base course If the quality of base course is unqualified, the quality of coating will not be ensured Warm reminder: as the basis of coating engineering, base treatment is the most important link in coating construction Unqualified base treatment will lead to serious coating problems, such as coating falling off, coating hollowing and coating blooming Therefore, it is recommended that you follow the standard construction process to ensure the realization of the five basic characteristics of the base 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,
