Core tip: high temperature, high humidity or drying alternately appear, which brings a lot of inconvenience to the citizens who carry out home decoration in summer Many details should be paid attention to if construction is needed in time Among them, paint is the most affected link If the treatment is not good or the construction is not standardized, the paint film will fall off, long hair, blister and other "sequelae", which will have a great impact on future life Decoration experts will explain the precautions for summer construction The first lesson Wall decoration Waterproof putty for wall "In the process of wall base treatment, puttying can Shenyang steel structure fireproof coating construction expert punde Building Fire Engineering Co., Ltd Recommended introduction: since its establishment, Shenyang punde Construction Fire Engineering Co., Ltd has cultivated a group of professional construction teams with excellent equipment, rich experience and serious responsibility with advanced and scientific management methods and strict engineering quality assurance and after-sales service system It has undertaken a number of fire system installation projects, which has been praised by customers Every idea and special requirement of you will be fully considered by us and fully realized in the construction technology, which will become the cornerstone of our successful long-term development We are looking forward to your invitation, to provide you with quality services and high-quality technical support! All construction coatings have passed ISO9001 Paint Home News: high temperature, high humidity or drying alternately appear, which brings a lot of inconvenience to the citizens who carry out home decoration in summer Many details should be paid attention to if construction is needed in time Among them, paint is the most affected link If the treatment is not good or the construction is not standardized, the paint film will fall off, long hair, blister and other "sequelae", which will have a great impact on future life Decoration experts will explain the precautions for summer construction Lesson 1 wall decoration wall can use waterproof putty "in the treatment of wall base, putty can play a waterproof, moisture-proof, anti powdering and anti mildew role." Jiang Liansheng, manager of the Engineering Department of Shanxi Branch of Beijing decoration (Group) Co., Ltd., a field expert, said that during the construction in summer, ordinary putty can be changed into waterproof putty to make the adhesion between the coating and the base more firm, not easy to fall off, and at the same time to avoid the yellowing of the wall caused by moisture When scraping putty in summer, pay special attention to the times of scraping and drying time Generally speaking, puttying needs 1-3 times, and the normal drying time is 1-2 days However, when putty is applied in rainy days, dry cloth shall be used to clean the water vapor on the wall and keep the wall dry as much as possible At the same time, the drying time of putty shall be extended as much as possible according to the weather conditions, generally 2-3 days "The putty needs enough time to dry If the putty does not dry completely, it will directly affect the coating in the future." According to the introduction, "when arranging the construction period, we also need to pay attention to the fact that this project should not be arranged too late In order to rush to the construction period and make this project proceed hastily, there will be endless troubles." How to choose latex paint "because latex paint requires strong adhesion, fine texture, good resistance to differentiation and permeability, so in home decoration, it is widely used by the walls of bedrooms and living rooms." Jiang Liansheng said, "the function of latex paint is very important It should be selected according to different parts of the paint For example, the latex paint in kitchen and bathroom should be waterproof, mildew proof and easy to wash." So, how to choose high quality emulsion paint? The inferior paint not only affects the construction quality, but also the unqualified chemical materials contained in it will harm human health We should try our best to buy the brand paint in the exclusive shop or special distribution shop "When you buy, you should carefully check the packaging, appearance and internal quality of the product." Jiang Liansheng said, after opening the lid, the truly environment-friendly latex paint should be waterborne nontoxic and tasteless, so if it smells of pungent smell or industrial flavor, then it is not genuine latex paint After a period of time, the surface of the genuine latex paint will form a very thick elastic oxide film, which is not easy to crack, while the defective paint will only form a very thin film, which is fragile and has a pungent smell Mix the emulsion paint with a wooden stick, and then pick it up from the last root The high-quality emulsion paint will flow down into a fan shape Touch with your fingers, the genuine latex paint feels smooth and delicate Jiang Liansheng told us that when the emulsion paint is applied to the wall and wiped with a wet cloth, the color of the genuine product is as bright as new, while the inferior product will fade with a light wipe due to poor connection and water resistance In addition, we must look at the ingredients when purchasing The ingredients of high-quality coating should be copolymerized resin into pure acrylic resin It should be noted that the impact of the rainy season on the wall painting of emulsion paint is not too great, but it should also be noted that the drying time of the wall after the first painting is properly extended Generally speaking, the normal interval is about two hours, and rainy days can be appropriately extended according to the weather conditions Lesson 2 the painting details of wood furniture should not be moved in rainy days In summer, the paint on the wall is easy to turn yellow or fall off Sometimes, there will be a piece of misty, white or bubbles These phenomena are caused by the alternation of drying and high humidity in summer Therefore, in summer, oil industry requires more work on the basis of construction details In particular, he said, it should be noted that oil projects must not be carried out in rainy days Because the paint is not easy to dry in such weather, which affects the construction quality When wood products are in rainy days, a layer of water vapor will condense on the surface At this time, if the paint is brushed, the water vapor will be wrapped in the paint film, making the surface of wood products muddy When painting nitrocellulose paint in rainy days, the color will be uneven; when painting, the phenomenon of whitening will appear If it is necessary to catch up with the construction period, a certain amount of white powder can be added to the paint Because the white powder can absorb the moisture in the air and accelerate the drying speed, but it will also affect the project quality So, try not to paint on rainy days In addition, before painting, it is necessary to ensure that the wood surface is dry and free of mildew and long hair Before painting for each time, it is necessary to ensure that the previous paint is dry and free of mildew and long hair After polishing, the next construction can be carried out Otherwise, the paint will fall off in pieces or cause the separation of paint film and wood surface Otherwise, after entering the autumn and winter season in the hot summer, tap the paint surface with the fingernail tip, and you will hear the sound of empty shells, which is basically caused by such problems What's the matter of mixed oil painting? Jiangliansheng said that mixed oil painting wood is one of the decorative means often used in home decoration Oil mixing refers to the use of ready mixed paint, enamel and other paint coatings to brush and decorate the surface of wood, so that the original wood color and wood grain pattern are lost on the surface of wood It is especially suitable for the use under the condition that the veneer of poor tree species materials is defective but does not affect the use, so as to achieve a more perfect decoration effect In the modern style of decoration, because the oil mixture can change the natural color of wood, the color is more abundant, and the material cost can be saved, it is favored by many decorators Special attention shall be paid to the bottom treatment of oil mixing process, and high hardness mud shall be used for batch scraping and priming Slight mould spots and improper mud scraping will cause the later paint film to peel off The wood production of oil mixing process must be closed properly to avoid moisture or moisture intrusion into the wood inner layer, causing wood production deformation or paint cracking, and special treatment must be carried out at the junction of line, line and panel, and painting can only be carried out after the special mud is patched Oil mixed painting is a high-tech construction project, which costs a lot of time Generally, it takes about 10 days to paint all the wood in three rooms and two halls According to the quality level requirements of paint, the number of wooden furniture, and the drying time of materials used, the construction period will change Then, what should the owner pay attention to when accepting the oil mixed painting? The type of paint used shall meet the design requirements, the color of the painted surface shall be the same, there shall be no brush marks, no peeling, missing brush, anti rust, whitening, bottom penetration, sagging, wrinkled skin, edge wrapping and uneven color and other defects, and the decoration line and color separation line shall be checked by pulling line, and the error shall be less than 1mm Lesson 3 don't put oil workers at the end of the project For projects that need to have a drying process, such as scraping wall putty on the wall and ceiling, it is difficult to dry quickly in summer After a layer of putty is scraped, the phenomenon of not drying out for a week is also common And putty is not dry will directly affect the coating in the future, and the most common problem is that the wall will "drum up" Therefore, in summer construction, puttying should not be carried out near the end of the project It is better to have a longer time interval, or to carry out construction on a sunny day The construction period in summer must be slightly longer than that in other seasons, and the construction period shall be extended appropriately according to the weather conditions and the suggestions of professionals, so as to avoid giving up the quality requirements due to the construction period guarantee In case of continuous rainy days or extremely humid weather, stop work properly with doors and windows closed If the paint surface appears white or blooming during painting, it shall be stopped immediately, polished and cleaned, and the construction can only be carried out when the air humidity is reduced Lesson 4 the national standard of ventilation volatile harmful substances is more detailed, the environmental protection test is more strict, there are more or less harmful substances in the decoration materials, in the normal construction, these harmful substances will be released to a large part of the outdoor quickly In the wet season, the air circulation is relatively slow, many harmful substances will remain in the interior or decoration materials Therefore, in order to release more harmful substances in this season, first, we need to increase indoor and outdoor ventilation Second, we need to keep the indoor as dry as possible Summer decoration, if the rainy weather is too much, latex paint will dry slowly, there are moldy taste and other problems Therefore, in the process of decoration, good ventilation should be kept indoors, and doors and windows should not be closed as much as possible After decoration, you can put more green plants in the room, let them play photosynthesis, remove peculiar smell, and put some fruits in the room, such as lemon, apple, pineapple, etc., which can also achieve the effect of removing peculiar smell 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,
