Coating process: construction process of water-based granite like coating

Core tips: first, the specific process of water-based granite like coating is as follows: 1 Process flow: For the treatment of wall base course, one time of anti crack mortar shall be applied by scraper (plastering) and the alkali resistant glass fiber mesh shall be compounded at the same time → two to three times of water-resistant putty shall be applied → one time of alkali resistant sealing primer shall be applied → line snapping, grid dividing and tape pasting → one to two times of intermediate coating of water-based granite paint → one time of main coating of water-based granite paint (spray to the required number of layers according to the pattern) → one time of smooth coating 2 Paint knowledge | precautions for wall paint color selection Recommended introduction: when painting the wall, the owner sometimes has difficulty in choosing what color of the wall paint to paint In fact, there is no ugly color in the wall paint, only the disharmonious color matching The use of wall color contains the knowledge of health Too strong color will stimulate people's perception, make people have a sense of fidgety, affect people's mental health Grasp the basic principles of wall color and paint a colorful space 1、 Wall paint color selection notice 1 Light color is generally used for the top surface Light colors make people feel light, dark colors make people feel heavy Usually, the treatment of rooms is from top to bottom, from shallow to deep For example, the ceiling and walls of rooms are white and Paint Home News: 1 The specific operation process of water-based granite like paint is as follows: 1 Process flow: wall base treatment bucket scraping (plastering) anti crack mortar 1 time and composite alkali resistant glass fiber mesh → scraping and applying water-resistant putty 2 to 3 times → brushing alkali resistant sealing primer 1 time → snapping line, dividing grid and sticking tape → 1-2 times of intermediate coating of water-based granite paint → spraying main coating of water-based granite paint (spray to the required number of layers according to the pattern) → spraying one time of gloss paint 2 Base surface treatment: before base treatment, the wall needs to be cured for a certain time Generally, the curing time of new cement wall is 28 days in winter and 14 days in summer After curing to the base, the pH value is less than 10 and the moisture content is less than 10%, the base surface treatment shall be carried out Before the base treatment, the loose, peeling, hollowing and powdered base shall be completely removed, and then the dust, oil and other pollutants shall be removed 3 Scratch and apply anti crack mortar with alkali resistant mesh: after cleaning the base course, prepare 2-3mm anti crack mortar according to the use requirements, at the same time, timely lay the mesh on the anti crack mortar, and press it into the anti crack mortar with a trowel Use anti crack mortar to level the part The total thickness of mortar shall be controlled at 2.5-3mm The scraping construction shall reduce the number of joints as much as possible, and the flatness shall be checked at any time with a guiding rule to ensure that the final vertical flatness is less than 2mm (2m guiding rule) 4 Scrape and apply the flexible water-resistant putty on the external wall: repair the wall with the flexible water-resistant putty on the external wall, level the first part, fill the large holes and gaps with the putty or joint sealant, polish the part after the putty is dry, and then apply the putty to make the base level The thickness of a scraping coating shall not exceed 0.5mm, and the construction shall be divided into two or more layers: the interval time of each layer shall not be less than 5 hours After each layer of putty is applied, it shall be polished and trimmed in time (generally 4-6 hours) The total thickness of flexible putty shall be controlled at 0.5-lmm 5 Brush the sealing primer: (1) tools and materials ① rough roller ② primer (2) after the putty meets the requirements, polish the base course and clean the floating dust before painting, keep the rough roller clean, brush the water-based sealing primer once, and brush evenly, without missing brush It is forbidden to mix water during the construction of water-based sealing primer 6 Brush the middle coat of water-based granite paint: (1) tools and materials ① rough roller ② middle coat of water-based granite paint (2) after the primer is dry, brush the main coat of water-based granite paint twice (3) after the middle coat is dry, check whether the lower paint surface is smooth and polish slightly with sandpaper if there are particles (this is not required for sand wall like midcoat) 7 Main coating of water-borne granite paint: (1) tools and materials ① spray gun ② air compressor ③ color spots of water-borne granite paint (2) construction of main coating of water-borne granite paint before spraying color spots of water-borne granite paint, the main coating of water-borne granite paint shall be fully dry, and the construction temperature must be above 5 ℃ When spraying granite paint, it is generally divided into two spraying The first time about 4-5 hours after the surface dry, spray the second time to achieve satisfactory results The coating amount will vary with the coating effect, climate, base condition and construction method The special spray gun for water-based granite paint shall be used for spraying The first construction shall be guided by professional personnel The products stored for a long time can be slightly stirred before opening the cover for use Mechanical mixing is not allowed, and water dilution is not required 8 Spray and roll coat the water-based granite varnish: (1) tools and materials ① spray gun ② air compressor ⑧ water-based granite varnish (2) pay attention to spray the varnish after the water-based granite like paint is completely dry (generally 2 days in sunny days) Pay attention to maintain viscosity, air pressure, nozzle size, and prevent sagging during construction Clean the floating dust before covering The spraying shall be uniform and comprehensive without leakage Generally, the spraying shall be at least twice to achieve good effect 2、 Precautions during construction: 1 After spraying the water-based granite paint color spot layer and before covering the light, make rainproof protection to avoid heavy rain washing, and cover the light as soon as possible after the water-based granite paint is dry 2 Construction environment: ensure that the ambient temperature shall be greater than 5 ℃ and the relative humidity shall be less than 70% Construction shall not be carried out in rainy days without strong wind or in rainy days Pay more attention to weather forecast during construction 3 Pay attention to construction safety and do not operate in violation of regulations Home of coatings is specialized in
