Walking on the street, we can see that the exterior walls of ancient buildings are generally painted, but after years of destruction, they have gradually become dull and have seriously affected the overall aesthetics. Therefore, in order to make these buildings a new look, you can refurbish the exterior walls. Then, what are the steps for refurbishing the exterior wall paint ? What are the precautions for refurbishing the exterior wall paint? Let's take a closer look!
First, what are the steps for the exterior wall paint renovation?
1. Clean the original wall surface
To make the walls look new and radiant, we first need to remove the previous paint. Then remove the severe skin and then apply a layer of white cement. However, if the wall surface is too smooth, it must be polished. Its main purpose is to facilitate the adhesion of new coatings and walls.
2. Apply primer and topcoat
After the base surface is disposed of, the next thing we need to do is paint on the bottom surface. The main purpose is: to resist the compound, resist moisture, close the base surface, make the topcoat free from damage, improve the texture and hiding power of the topcoat. Therefore, the primer on the old house is essential, otherwise there will be wall blistering, mildew, discoloration and other conditions. After the paint dries out, it can be brushed. Generally, it can be brushed twice.
3. Large area repair
After the primer has been brushed, if you are only partially refurbishing, the color difference is likely to occur. Because the materials have different use times, it is difficult to achieve the desired effect, and the repair is also troublesome. Therefore, it is advisable to renovate the exterior wall paints to renovate the whole wall surface or to repair it as large as possible. This will prevent chromatic aberrations and improve the quality of repairs.
Second, the external wall latex paint construction precautions what?
1. Influence of construction temperature
We all know that the outdoor temperature is high and low, but generally outside the wall when the paint temperature should be controlled at 5 degrees Celsius above, so if it is in the cold winter, only at noon maximum temperature can be construction. In addition, due to the lower temperature in the morning and evening, construction workers must adjust the construction time in time, otherwise there will be poor film formation on the part of the wall coating.
2. Influence of construction humidity
In fact, outdoor moisture will also have a certain impact on the wall construction. In general, the wall will be wet when it is finished, so it is not possible to paint.
3. The impact of the underlying processing
Many people do not attach importance to exterior decoration during the renovation process. Therefore, the use of low-strength putty on the base surface treatment is actually wrong. Because the quality of putty will directly affect the overall appearance.
