is a big project. Due to the complexity of the wall substrate and the different materials and techniques used, it is more troublesome to carry out wall treatment. So, does all the putty have to be removed?
Wall Finishing
And what are the
What are the precautions
What are the precautions? I will take you to understand what problems need to pay attention to secondary decoration walls.
Wall paint full “five years old” must be eradicated
Removal of the old wall surface attachment is the second renovation must be carried out in a job, generally including the eradication of the original wall emulsion paint and putty layer, the original wood decoration, the original other surface decorations such as wallpaper and other removal.
The removal of the original emulsion paint and putty layer is the basic construction that all secondary renovations must be carried out. In the 1990’s and beyond, water-resistant putty was gradually promoted and used on interior walls. This water-resistant putty is both time-consuming and labor-intensive, and it is easy for the construction team to cut corners in this area. If the room has only been renovated for one or two years, the water-resistant putty can be completely removed and the wall can be repainted with emulsion paint after sanding with steel brushes and sandpaper. It is important to note that water-resistant putty over five years old must be removed to the bottom of the wall during the second renovation due to aging of the material, otherwise it will affect the construction quality of future wall emulsion paint and the long-term use effect after renovation.
Demolition and alteration of walls to ensure safety
Reasonable demolition is beautifying and toning. The wall can expand the living room or bedroom space, the original wall demolition into a new window and door openings, etc., but the premise of demolition is to consider the overall structural safety of the residence.
According to the relevant regulations, “non-load-bearing walls can be considered for demolition.” In the current residential building, residential in the original design and construction for reasons of cost, structure and technology will be a large number of lightweight walls as a supplement to the main structure outside the material, including aerated concrete wall panels, ceramic block walls, light steel keel gypsum board walls, hollow cement prefabricated panels, magnesia cement prefabricated panels, etc.. In addition, depending on the age of the building, there are also some red machine brick, light masonry block and other masonry walls can also be demolished, but must be done carefully.
In the demolition of the wall, the power should be cut off in advance to avoid accidents. The original power lines and weak lines to be retained, it is best to mark and record in advance, construction cut off the line dump must leave enough surplus to facilitate future wiring. Owners should advise workers that it is best not to cut off video lines and broadband lines to prevent signal failure after renovation. Certain walls adjacent to kitchens and bathrooms are best not to be demolished, as demolition will damage the integrity of the waterproof layer and affect future residential safety.
Wall renovation should pay attention to 5 points
1, the wall to clean
Old walls must be done before renovation of wall substrate treatment, chalking serious to all eradication, eradication with white cement on once. The original wall is too smooth, painted after eradication, but also to do sanding treatment, the bond is not firm to remove the skin, to facilitate the new paint and wall bonding.
2、Primer is indispensable
The role of wall primer is to resist alkali and moisture, seal the substrate, protect the top coat, and improve the texture and coverage of the top coat. For the old room renovation, the wall must be primer, directly on the paint, the future wall is easy to blister mold, sun exposure over time is also easy to discoloration.
3, repair to be comprehensive
For the repair of painted walls, it is relatively difficult to achieve the desired effect. So for the wall has been injured its best to repair the whole wall or as far as possible to choose a larger area for repair, so that you can constantly try to avoid color differences, the quality of the repair is also better.
4, repair anti-color difference
Wall color difference, which is to try to avoid when repairing the wall. For this reason, you should pay attention to the ratio and painting according to the instructions of the paint bucket, and it is best to estimate the amount. It is quite important to prepare enough amount at one time, so as to ensure the color of the wall is consistent. Although the paint factory provides the color card, the effect may deviate due to the strong alkalinity of the old wall itself.
5、Pay attention to ventilation
The ventilation of old houses is poor, and the xylene component in the thinner will react chemically with the components in the latex paint, leading to yellowing of the walls. So to strengthen the ventilation, really can not, have to place a few electric fans to strengthen the ventilation effect.
