Wall renovation is a complex project, which needs different treatment according to different building structures and materials. Here are some common wall renovation methods.
1. Surface cleaning and painting. For long-term weathering, pollution and degradation of old walls, surface cleaning and painting can be used for renovation. In the cleaning process, you can use water, high-pressure water pipes and other tools to clean up the dirt, oil stains, dust, etc. on the wall, and then coat the surface with suitable waterproof and pollution-proof materials for protection.
2. Replace bricks and stones. Bricks or stones that are seriously aged or damaged need to be replaced. In this case, it is necessary to remove the aged or damaged parts and then rebuild the new masonry wall.
3. Strengthen the wall structure. For some old walls, there may be loose structures or components falling off, which need to be strengthened. Strengthening work includes re-fixing the wall structure and replacing loose or damaged building components.
4. New external wall insulation layer. When building or rebuilding some high-rise buildings, we can consider adding insulation layer outside the wall to ensure the comfort and energy-saving effect of indoor temperature.
In short, the wall decoration needs to be handled according to the specific situation, and the appropriate treatment method can be selected according to the materials, conditions, safety and other factors of the wall to ensure the long service life, beauty and practicality of the wall.
