Coating technology: water based pure acrylic thick paste pattern modeling elastic exterior wall coating construction technology

Core tips: 1 Water based coating, pure acrylic thick paste pattern, elastic exterior wall coating base treatment: (1) When painting the original building, the bond strength test shall be carried out for the external facing, and the bond strength shall be ≥ 1.0MPa In case of hollowing, delamination and other phenomena on the base surface, the original external wall facing layer shall be removed, and the exposed base wall shall be plastered again If it is polluted by oil or floating ash, it shall be removed, and the interface agent shall be fully applied (2) The moisture content of the base course is less than 10%, and the pH value is less than 9.5 2 Construction conditions of water-based pure acrylic thick paste pattern elastic exterior wall coating: (1) External wall coating application 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 Coating home news: 1 Water based coating pure acrylic thick paste pattern elastic exterior wall coating base treatment: (1) when coating the original building, the external facing shall be tested for bond strength, with bond strength ≥ 1.0MPa In case of hollowing, delamination and other phenomena on the base surface, the original external wall facing layer shall be removed, and the exposed base wall shall be plastered again If it is polluted by oil or floating ash, it shall be removed, and the interface agent shall be fully applied (2) The moisture content of the base course is less than 10%, and the pH value is less than 9.5 2 Construction conditions of water-based pure acrylic thick paste pattern elastic exterior wall coating: (1) the construction of exterior wall coating shall be carried out after the acceptance of the basic wall works (2) Before the construction of exterior wall coating, the exterior wall door and window frames must be installed and accepted (3) The construction site shall be electrified and watered and the working environment shall be kept clean (4) The ambient temperature and the surface temperature of the base wall shall not be lower than 0 ℃; the wind force shall not be greater than grade 5 The most suitable construction temperature is 15 ℃ - 35 ℃ (5) In summer, it is not suitable to construct under direct sunlight Construction is not allowed in rainy days (6) Artificial scaffolds should be used for exterior wall coating construction, and holes and other sundries that hinder the construction should not be reserved on the wall 3 Construction method of water-based pure acrylic thick paste pattern elastic exterior wall coating: (1) conduct a comprehensive inspection on the base surface, such as spatula traces, rough corners and edges, exposed nets and other phenomena, and repair them; if the wall surface is uneven, the putty shall be scraped and leveled (2) The construction can only be carried out after the putty is completely dry (3) Construction method: roll coating, brush coating and spraying (4) The tools used in the construction shall be kept clean and dry After the construction, they shall be cleaned in time and immersed in water for reuse the next day (5) Before using the paint, use the electric hand-held mixer to properly mix to a stable and even state, and do not over mix (6) Use wall corner, deformation joint, dividing joint, back of downpipe or independent decorative line to divide the area The wall or independent wall in one area is painted at one time (7) The same batch of paint shall be applied to the same wall Each coat shall not be too thick, and the coating shall be uniform with the same color (8) Before the construction of main materials, the base surface shall be painted with a layer of colorless primer The dosage is 0.1-0.15kg/m 2 (9) After the primer is dry, a layer of thick paste pattern molding material shall be brushed with a special roller brush, and the second layer of molding material shall be partially brushed after drying Mix the main material evenly before painting, and the dosage is 0.6-1.0 kg / M 2 (10) After drying for 24 hours, apply kl-tws-6 elastic coating twice 5% - 10% water shall be added to dilute the main material for the first time, and no dilution is required for the second time The interval between two times of main material is more than 24 hours In case of exposed bottom, it shall be repaired within 2 hours Dosage: 0.3-0.4 kg / M 2 (11) 24 hours after the completion of coating construction, spray a layer of finishing coat The dosage is 0.1-0.15kg/m 2 4 Precautions for construction of water-based pure acrylic thick paste pattern elastic exterior wall coating: (1) water is drinking water (2) According to the wall humidity, air temperature, the main material consistency and wind speed, the water can be adjusted appropriately (3) The same painting tools shall be used, and the lines applied shall be the same before and after, and the color shall be the same The wall surface of the construction coating shall be provided with rainproof and pollution prevention measures (4) A set of painting tools shall be used for a kind of color coating The interface shall be horizontal and vertical, and the two main materials shall not be interpenetrated together (5) After rain, the moisture content of the base course shall be checked The moisture content shall be less than 10% The test method is to stick a square plastic cloth on the wall with tape around the plastic cloth, and observe whether there is any water drop on the plastic cloth when the sun shines for about 1 hour If there is no water drop, the construction can be carried out, otherwise the construction cannot be carried out 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,
