How to deal with the exterior wall decoration?

Basic steps of external wall renovation

Wall cleaning: the old wall surface must be treated with wall foundation before decoration, and the wall surface with serious pulverization should be completely removed, and then a layer of white cement should be applied after removal. For those that are too smooth and painted, it is necessary to polish and remove the skin that is not firmly bonded, so as to facilitate the bonding between the new paint and the wall.

Primer coating: The function of wall primer is to resist alkali and moisture, seal the substrate, protect the topcoat, and improve the texture and hiding power of the topcoat. In the renovation of old houses, the walls must be primed. If you don't apply the primer and directly apply the topcoat, the wall will be prone to foaming and mildew after a long time, and it will also change color after being exposed to the sun for a long time.

Large-scale repair: It will be more troublesome to repair the wall with a good topcoat, which is easy to produce color difference. It is difficult to guarantee the quality of materials with different use time, and it is difficult to achieve the ideal effect. Therefore, the repair of the wall is the whole wall, or try to choose a larger area for repair, so as to avoid color difference as much as possible and the quality after repair is better.

Anti-chromatic aberration: When repairing the wall, it is necessary to avoid chromatic aberration of the wall as much as possible. So pay attention to the proportion and paint according to the instructions of the paint bucket, so as to estimate the dosage. Prepare enough at one time, so as to ensure the consistency of the wall color, and also avoid the difference of the rearranged colors due to insufficient dosage.

Matters needing attention in exterior wall decoration construction:

2. When the doors and windows of the facade are removed, the permission of the residential property or housing management department must be obtained in advance, and it is a residence facing the main street.

If the wall is demolished or new doors and windows are opened due to the need to adjust the indoor layout, remember not to dismantle the load-bearing wall, because the load-bearing wall is related to the safety of the overall structure of the house. The demolition of ordinary walls should also obtain the consent of the property right or the housing management department in advance.

4. Understand the laying direction, location and diameter of water and electricity pipelines in the community, and communicate with the home improvement company about the decoration scheme. If there is any requirement to change the gas system, it should be changed through the gas department. For some intelligent systems and preventive systems installed in houses, it is necessary to contact professional manufacturers or properties in advance to take protective measures.
