Coating technology: medium (high) level (with) light exterior wall coating construction technology

Core tips: 1 Base treatment of medium (high) level (with) light exterior wall coating (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 10 2 Construction conditions of medium (high) level (with) light exterior wall coating (1) The construction of exterior wall coating should be accepted in the basic wall engineering 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 Paint Home News: 1 Base treatment of medium (high) level (with) gloss exterior wall paint (1) when painting the original building, the bonding strength test shall be carried out for the external facing, and the bonding 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 10 2 Construction conditions of medium (high) level (with) light exterior wall coating (1) the construction of exterior wall coating shall be carried out after the acceptance of 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 medium (high) level (existing) light exterior wall coating (1) conduct comprehensive inspection on the base surface, such as spatula traces, rough corners and edges, exposed nets and other phenomena, and repair; if the wall surface is uneven, apply leveling putty The construction can only be carried out after the putty is completely dry (2) Construction method: roll coating, brush coating and spraying (3) 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 (4) Before using the paint, use the electric hand-held mixer to properly mix to a stable and even state, and do not over mix (5) 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) The construction is usually completed twice, adding 10% - 15% water for the first time and 5% - 10% water for the second time The interval between two times of main material is more than 4 hours In case of exposed bottom, it shall be repaired within 2 hours (9) According to the wall humidity, air temperature, the main material consistency and wind speed, the water can be adjusted appropriately (10) 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 (11) 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 (12) Main material consumption per square meter: flat light: 0.3-0.4 kg / m2; Light: check the moisture content of the base course after the construction of 0.25-0.30 kg / m2 (13) rain, and the moisture content should be less than 10% The inspection method is to stick a square plastic cloth on the wall with tape around the plastic cloth, and observe whether there are water drops on the plastic cloth after the sunshine for about 1 hour If there are no water drops, 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,
