With the improvement of living standards, everyone has also greatly improved the comfort of the building. The pace of winter is approaching and the temperature has dropped. Has the external thermal insulation wall started to protect your home against cold and warming? After a long time of use, the external thermal insulation wall will have problems for various reasons. The original building exterior lacks insulation, but now the external walls of the building are already The insulation layer, but everyone's requirements for insulation are constantly changing. Then how to do the insulation of home exterior wall can meet the requirements of everyone? What about home furnishing decoration ?

Exterior wall painting
1. At present, there are two main methods for the painting of exterior walls: hanging plates and baskets.
2. The way of hanging board is to lift the person to work position with hanging ropes and hanging board. General buildings can be cleaned in this way. However, this type of operation must ensure that safety measures are in place. Otherwise, the dangers are very high. All accidents and injuries are caused by failure of safety measures.
Exterior painting conditions
1, climatic conditions
The painting of exterior walls must be carried out under good weather conditions. The wind power should be less than 4 and the work above level 4 should be stopped. Therefore, wind power should be measured before work, especially high-altitude wind power. In addition, it is not suitable for exterior wall painting under conditions of rain, fog, and poor visibility of snow, high temperatures (above 35°C) and low temperatures (below 0°C).
2, personnel conditions
High-altitude operators must be male citizens who have reached the age of 18 years. After undergoing physical examination and safety technical training, they will be allowed to work after passing the examinations. Workers must not drink alcohol before taking up jobs, and suspended high-altitude operations if they have symptoms such as colds.
3, equipment conditions
The external wall painting equipment must be in a good working condition, where new ropes should be replaced immediately when the hanging board has hairs and some strands gradually crack.
Basic construction plan
1. The surface of the new cement mortar and concrete needs to be ventilated and dried for a period of time to allow the walls to be fully dried, so that the wall moisture content is less than 10%, and the PH value is less than 10 to be used for construction. Usually at 25 degrees and 65% relative humidity, the cement mortar wall surface should be dried for more than 7 days, and the concrete wall surface should be dried for more than 21 days.
2. Cast-in-place or prefabricated cement concrete substrates require a longer curing period and thoroughly remove the surface release agent.
3, for the weathered concrete base, highly absorbent and rough sanding cement plaster layer, should be applied through the wet brushing process primer treatment.
4. The base layer of white pantolite is whitened out. Remove the crystals with a steel brush and wash it repeatedly with 5% aqueous oxalic acid solution. Then rinse with clean water.
5. For the old coating with no load-bearing capacity, looseness, and peeling, it should be completely removed together with the putty, washed and dried, then leveled with putty. For a lightly pulverized but solid old coating, smooth it with a primer. The heavily powdered old coating should be thoroughly cleaned in advance and the old oil paint should be completely removed.
6. The grassroots with serious pollution should be clean. The wall that has been eroded by molds and algae is mechanically removed. It can also be treated with an aqueous bleach solution, rinsed with water, and leveled after drying.
7. Locally deep grooves should be filled with cement mortar first, and local protrusions should be flattened first. The primary wall must be solid and firm before scraping the putty, and there should be no defects such as sanding, cracks, and looseness.
8, wall damage, cracks, uneven and other parts in the primer before the use of external wall repair putty waterproof. The thickness of each batch of putty is controlled within 2mm, and the total thickness of batch putty is no more than 5mm. The putty should be solid and firm, and should not be powdered, peeled or cracked.
9, after the child is dry, use sandpaper to polish formation, and then wipe the putty on the putty with a damp cloth, and paint as soon as possible to avoid falling again.
10. The surface to be coated must be solid and firm, and there should be no defects such as sand removal, cracks, loosening, and spalling. The coated surface must be clean and free from dust, dirt, oil, mold, and other attachments.
Home exterior wall insulation how to do
The wall insulation performance of the house is good, mainly depends on the insulation layer of the wall. Room walls are divided into exterior walls and interior walls. The exterior wall refers to the external maintenance structure of the building, and the interior wall refers to the partition wall between the interior room and the room of the building. Currently, the wall insulation of the building is for the exterior wall. The interior wall does not require insulation because it takes into account that the temperature difference between adjacent rooms is not large. The wall insulation layer has two kinds of outer insulation layer and inner insulation layer. The construction methods and insulation effects of the two insulation layers are different.
First, external wall insulation
External insulation, as the name suggests, is a kind of insulation practice that places the insulation layer on the outside of the main wall material, because it can reduce the impact of the cold bridge, and protect the main wall material from much temperature deformation stress, and is the most widely used insulation practice at present. It is also the current practice of national warming advocated.
Second, the outer wall insulation
Exterior wall insulation is also a traditional way of insulation, which is to put the insulation layer inside the main wall material insulation practices. The internal insulation itself is simple and the construction cost is low, but it is easy to deal with the thermal bridge. In recent years, due to the rapid development of the external insulation and the application of the national policy guidance in China has been reduced. However, in the hot summer and cold winter and summer hot and winter areas in China, there is still a lot of application space and potential.
Third, external insulation PK insulation
The wall insulation layer is built by the house construction unit and generally does not require the residents to do it by themselves. However, if the house built by the developer does not have insulation or thermal insulation, it will require the residents to find a solution. Therefore, it is always good to understand some of the relevant knowledge about wall insulation. There are generally two types of insulation on the walls of a house to compare the two types of insulation.
Fourth, wall insulation
The current housing construction generally adopts the practice of adding outer insulation layers, but if some old buildings are old due to their age, no insulation layer is added, and a professional construction company can be invited to do the exterior wall insulation layer. Adding the outer insulation layer is troublesome. It is necessary to coordinate and communicate with the property in advance. And if you want to keep warm, you can add inner insulation. Because the construction of the inner thermal insulation layer is relatively simple, it can be done by the decoration company or on its own.
Editor's summary: The related information about how to decorate the home wall and how to do it in the insulation of the home's exterior wall is introduced here for everyone. I hope this article will help everyone. If you still have something you don't understand, you can leave a message to Xiaobian at the bottom. We will answer your questions as soon as possible.
