Some houses are in the wind, the sun, the rain, the outer wall looks good, but some houses seem to be worn out, this is mainly the effect of exterior paint, the exterior paint can protect the house. It has good enough water resistance, weather resistance, stain resistance and freeze-thaw resistance to ensure good decorative effect and durability. Therefore, the construction of exterior wall paint of the house is very important. Let's take a look at the exterior wall. Paint construction plan situation: Exterior wall coating construction plan: First, painting detailed construction specifications After inspection of walls that have met the construction conditions, the attachments, such as cement mortar particles, should be removed first. Before the construction, the wall surface is measured by professional instruments, the water content is less than 10c/o, and the pH value is less than 10, which ensures the best effect of the paint. If the ph value does not reach the construction conditions, use 1 kg of oxalic acid with 50 kg of water to rinse to meet the construction requirements. Small cracks and large unevenness should be filled by corresponding measures to make the surface of the wall smooth, firm and clean. Second, the pre-processing of different bases 1. New cement mortar wall (1) There is a mortar, which is smoothed with an angle grinder. (2) If there is a hole, fill it with cement mortar. (3) If there is an empty drum, knock it out with cement mortar. (4) If there is a pan-alkali phenomenon, it is treated with oxalic acid to achieve neutrality. 2, mosaic surface or tile surface (1) Remove the empty drum and loose parts. (2) Cleaning surface dust and oil. (3) Fill the surface holes and brick joints with cement mortar or leveling putty. (4) A batch of interfaces to level the putty together. 3, the old coating base (1) Remove the powder, the shell and the soft parts, and clean them. (2) Fill the holes with putty. 4, clean the base of the brick wall (1) Remove the weathered surface and clean it. (2) Fill the brick joint with the leveling putty first, and then level the putty. 5. The base layer where cracking has occurred First fill the seam with elastic putty, and apply a piece of elastic putty around the crack and compact it with a batch of knives. After drying, the second elastic putty is scraped off, and after the elastic putty is dried, the next process can be carried out. Third, the special scraping of the external wall putty In order to ensure the integrity of the topcoat, the special screed putty for the external wall is used, which has good adhesion, high strength, crack prevention and foaming. Use the special screed putty for the external wall to carry out the overall scraping of the wall. It is required to scrape less than 3mm per batch. It is recommended to apply multiple layers of thin layers. After the batch is scraped, the uneven parts will be repaired and repaired, and the unevenness will be scratched. The place is smoothed and thoroughly dried and cured. 1. Description of construction process Use a batch knife to fill a piece of putty in the horizontal direction on the divided plate, and use a scraper to scrape horizontally in the horizontal direction. The recessed place is filled with putty and then flattened. After the surface is dry, fill the putty together in the vertical direction, then use the other scraper to scrape vertically in the vertical direction. If there is a depression, fill it with a special putty on the outer wall and then shave it vertically. If the flatness still does not meet the requirements, repeat the above steps until the requirements are met. 2. Construction process requirements (1) The thickness of each batch scraping should be less than 3mm. (2) Flatness requirement after completion: 2 meters by foot inspection, flatness error is less than 3mm. After drying for 24 hours after construction, it is smoothed with 400# sandpaper. After completion, the surface should be smooth and fine, without scratches and sand marks. 3, process flow chart (putty and exterior wall paint) (1) Construction process of screed putty for exterior wall paint (2) Exterior wall paint construction process Fourth, repair, clean up, acceptance After all the processes are completed, the final inspection shall be carried out. If there are imperfect, contaminated or damaged places, repair immediately, clean the protected area, clean up the site; continue to do the protection work; prepare for acceptance. The construction of exterior wall paint is related to the service life and decoration effect of the house. It is an important project, so we should not ignore it. The construction plan of the exterior wall paint will be introduced to you here. I hope to help everyone.
