Core tips: diatom mud construction process: wall cleaning → bottom putty → base putty polishing → first diatom mud → second diatom mud → diatom mud pattern production → finished product protection → acceptance 1、 Base putty construction 1 Clean the wall First, clean up the dust and slurry particles on the wall, level the bumps and potholes with gypsum, grind off the protruding parts with sandpaper after drying, and clean up the floating dust For the wall of calcium silicate board, the joint of calcium silicate board shall be caulked first Paint agent, top 10 Chinese wall paint brands Recommended introduction: interior wall paint and exterior wall paint can achieve beautiful, clean and pleasant effects, but the effects in different environments are different, so the color of the paint will be different There are ten brands of Chinese paint, ten brands of global paint, ten brands of Chinese wall paint, and ten brands of Chinese paint, Famous trademark of Chinese paint and coating In private rooms, most of us choose according to our own personality, personal hobbies and living habits The younger generation will choose the interior wall paint with rich colors and bright colors, while the older ones will have some working experience Coating House News: diatom mud construction process: wall cleaning → bottom putty → base putty polishing → first diatom mud → second diatom mud → diatom mud pattern production → finished product protection → acceptance I base putty construction 1 Clean the wall dust and slurry particles first, and use gypsum Level the bumps and potholes on the wall, grind off the protruding parts with sandpaper after drying, and clean the floating dust For the wall of calcium silicate board, the joint of calcium silicate board shall be caulked first Dacron cloth shall be used at the junction of different materials, and the width shall not be less than 100mm For the parts with large structural deviation, the bottom layer + surface layer shall be used for plastering, the thickness of each layer shall not exceed 4mm, and the next layer shall be carried out after drying After the flatness meets the requirements, putty construction shall be carried out 2 The water-resistant putty is prepared to be mixed according to the proportion of water-resistant putty powder: water = 1:0.4-0.5 After 10-30 minutes, it can be used after fully mixing again 3 The number of times of applying water-resistant putty on the wall can be determined by the flatness of the wall, generally three times For the first time, the rubber scraper shall be used for full horizontal scraping, one scraper shall be followed by another, and the joint shall not be stubble left, and the end of each scraper shall be clean After drying, sanding paper shall be used to polish the floating putty and spots, and then the wall shall be cleaned For the second time, the rubber scraper shall be used for vertical full scraping, and the materials and methods used shall be the same as for the first time of putty After drying, the sandpaper shall be ground and cleaned For the third time, use rubber scraper to repair the putty or steel scraper to fully scrape the putty, scrape the wall flat and polish it with fine sandpaper after drying, and do not omit or grind the putty through The thickness of each time of putty shall not be too large The first time of scraping putty shall be leveled, and the thickness of putty shall be 0.5-0.8mm and even The thickness shall not be more than 2mm, generally 1-2mm Putty is mainly scraped, pressed and polished It is even and has smooth effect For knots and unevenness, sandpaper is used to polish 2、 The construction of diatom mud surface layer 1 First, prepare clear water according to the construction amount, add 90% of the construction water in the mixing container, then pour in the diatom mud dry powder to soak, after soaking, use the electric mixer to mix for about 20 minutes, and add another 10% of the water at the same time of mixing, fully mix and evenly before use It is better to use the product after mixing with water on the same day The professional and technical personnel shall formulate the diatomite formula according to the site climate conditions, add water in proportion to the raw materials according to the method provided by the manufacturer, and mix for a certain period of time on site to make the mixture fully dissolved and fully reacted On site mixing method: A pour 90% clear water into a large container, and then pour diatom mud powder b Mix well with a small high-speed mixer c The remaining water (10%) shall be used for adjustment during mixing 2 Diatom mud shall be applied in two times The first time (about 1.5mm thick) shall be applied for about 50 minutes (depending on the weather conditions on site, it is better not to stick hands on the surface, and the material shall be used for leveling in case of exposed bottom) The second time (about 1.5mm thick) shall be applied After daubing, use a spatula to polish, and then use a tool to make a pattern The pattern takes a long time to make, and some patterns need to be polished again after completion 3、 The environmental requirements of diatom mud construction are as follows: 1 The relative humidity must be less than 80% and the water content of the base surface must be less than 10% 2 The construction temperature of the fabric is - 5 ~ 40 ℃, avoid construction in direct sunlight in summer 3 In the process of construction, pay attention not to use air conditioner, fan or window ventilation Too fast drying increases the difficulty of texture construction 4 It is not suitable to construct under 5 ℃ 5 Outdoor construction is prohibited in severe weather such as rain, snow and hail 6 In case of other technical problems, please ask professional technical personnel to deal with them 4、 Precautions for diatom mud Construction: 1 The base with hollowing or cracks shall be treated in advance, and the base shall be coated with putty twice after cleaning 2 In the construction process, direct wind and direct sunlight exposure shall be avoided, and natural drying shall be preferred 3 Diatom mud is a kind of water-soluble facing material, which can't be used in the place directly soaked by water 4 It is normal that the physical properties of natural raw materials, including their color differences, do not affect the product quality 5 Diatom mud should not be constructed under 5 ℃ Do not eat diatom mud, avoid entering eyes 6 Keep a safe storage distance with children and strengthen labor protection when using 7 Before the construction, the protection of the existing finished products shall be done well, and the places outside the construction surface shall be protected in advance with curing materials 8 The base with hollowing or cracks shall be treated in advance, and the base shall be coated with full oil or pre scraped down if necessary 9 Add clean water in strict accordance with the specified proportion, and fully mix with electric mixer 10 Avoid direct sunlight exposure during construction 11 Due to the need for skilled technology to make a wonderful shape, special technicians must be employed for construction 12 It should be used as early as possible after opening 13 Special materials for indoor use, not for outdoor use 14 Do not add other ingredients 15 Clean water must be used 16 Add clean water in strict accordance with standard quantity to avoid color difference of finish 17 At the beginning of mixing, it may be sticky and laborious, so you only need to continue mixing to brush 18 Waterproof and moisture-proof during storage and transportation Avoid placing directly on wet ground 5、 Finished product protection 1 The process of putty coating engineering and other processes shall be reasonably arranged to avoid repair work in other processes after coating process 2 When painting, the indoor doors and windows, glass, plumbing lines, electrical switch boxes, sockets, lamp holders and other parts that are not brushed shall be covered with waste newspaper or plastic film in time 3 It is forbidden to drag on the ground when moving construction tools such as slurry barrel and shotcrete machine to prevent damage to the ground 4 Before drying, the pulp film shall be protected from dirt and hot air 5 When removing the shelf or moving the high stool, pay attention to protect the painted wall 6 It usually takes 48 hours for diatom mud to dry completely Do not touch it within 48 hours After 48 hours, you can spray a small amount of water with a watering pot After drying, dry clean towel or sponge foam is used to remove surface floats Home of coatings is specialized in coatings, diatom mud, paint
