There are many kinds of exterior wall paints. Different types of exterior wall paints require different construction process requirements. Today, let's take a look at the water-based exterior wall paint construction process and the water-based exterior wall paint construction precautions. I hope to be helpful.
Waterborne exterior wall paint construction process
Step process:
Base surface treatment → acceptance After the outer wall base is qualified, start the construction → apply the brush and seal the primer → apply the brush to the middle coat of latex paint → apply the brush to the top coat of latex paint → clean up and maintain → check and accept the exterior wall effect.
Construction method:
1. Prior to construction, the external wall should be treated with foundation. The loose, peeled, empty drum, and powdered grassroots should be thoroughly removed. Then the dust, oil, and other pollutants should be removed. The wall surface should be uneven and should be filled with flat putty. Do not dry before construction.
2. Perform a thorough inspection of the base surface, such as the traces of spatula, rough corners and edges, and the appearance of the exposed net, etc., and perform a thorough secondary repair. After the acceptance, pass the construction.
3. Make sure that the tools, amount of paint, and the wall surface of the paint are ready. The tools used during construction should be kept clean and dry. The construction should be cleaned and immersed in water to ensure the secondary use effect. The same wall should be used for the same batch of paint. .
4, first brushing the sealing primer, adding 10% -15% of water in the exterior primer to dilute, fully stir evenly after brushing, require uniform coating, can use wall corners, deformation joints, sub-grid Sewage, behind the downspout, or separate decorative lines to partition, the walls in a partition need to be applied once. The interval between the construction and the next construction shall be no less than 12 hours. If there is any exposed floor, it shall be repaired within 2 hours.
5, followed by brushing paint latex paint, generally in the external wall paint plus 5 ~ 10% water dilution, after the full mixing of the construction, roller coating together can be. Also require uniform coating, no sagging, no leakage. After the construction, the interval between the construction and the next process shall not be less than 4 hours. The appearance of the exposed bottom shall be repaired within 2 hours. Otherwise, uneven distribution of the paint may occur.
6, then brushing the top coat of latex paint, generally add 5 to 10% water dilution (or undiluted), after the full mixing of the construction, roll coating can be. Require uniform coating, no sagging, no leakage.
7. The next step is to clean and maintain the external walls. After completion, the walls should be protected against rain and pollution, so as to avoid damage to the dry exterior wall coating, thus affecting the decorative effect.
8, the final is the acceptance of the external wall, according to the specific construction requirements and specification acceptance.
Precautions:
Pay attention to the temperature and humidity of the construction environment when performing the exterior wall paint spraying process. The construction temperature should be 5~35°C, the ambient humidity should be less than 75%, and construction in rain, snow, fog, and windy weather should be avoided. Twelve hours before the rain, construction should not be carried out 24 hours after the rain, and rain or external damage should be avoided within 8 hours after the completion of construction.
The data and content mentioned above will have certain deviations in practical application and should be determined according to the specific circumstances. The waterborne exterior paint construction process and precautions are briefly introduced here and I hope to help you. For more information, please visit this website. Stay tuned.
