If you are familiar with putty scraping at home, you will know that there are two most difficult positions to handle when scraping putty at home. The first position is the external corner of the wall, and the second position is the internal corner of the wall. If these corners of the wall, if not handled properly, curves will appear in the later stage, which is very unsightly. At present, PVC corner protectors are commonly used to treat male corners. So, how to use PVC corner protectors? For example, a friend now asks a question: How do PVC corner protectors stick when applying putty?
What is a PVC corner protector?
PVC corner protector is a material made of PVC plastic material, used to protect the construction of wall corners. PVC corner protectors appear as L-shaped lines in appearance. The two sides of this corner guard are perforated, and the faces are perpendicular to each other, forming a 90 degree right angle. The PVC corner protector is used for the external corners of the wall. For example, for the corners of walls, columns, and so on, the function of corner protectors is to protect these corners and facilitate the final shaping of putty, which can achieve a perfect 90 degree right angle. This looks very beautiful from the outside and is very conducive to shaping.
How to paste PVC corner strips?
The first step is to apply a thin layer of putty on the exposed corners of the corner protector strip. The function of putty is to facilitate us to stick the corner protector to the external corner. After scraping the bottom layer of putty, we can then fasten the corner protector to the external corner, so that the corner protector can be stuck to the external corner. The second step is to apply putty. After fixing the corner guard strip, we can apply putty. At this point, it is usually the first layer of putty scraped, which is the bottom layer of putty. When scraping the bottom putty, it is necessary to cover the entire corner protector strip, to achieve the specific function of the corner protector strip. The third step is to apply the second coat of putty. After the first layer of putty reaches its strength, it usually takes more than seven days. At this time, we can apply the second layer of putty. Using putty here can roughly level and seal the entire wall, ultimately creating a beautiful corner.
Why can the corner protector stick to the male corner?
The first point is to understand the specific structure of the corner guard strip. The PVC corner guard is made of plastic material, and this corner guard has two faces in total, which are perpendicular to each other. The most important thing is that it has holes on both sides, with a diameter of about 10mm and a spacing of about 5mm between holes. Let's take a look at why corner protectors can be attached to the corners. As introduced above, when pasting corner protectors, we first apply a layer of putty on the wall, and the specific location is where we paste the corner protectors. Then, we can press the corner protectors to the position where we apply the putty. At this point, everyone can notice that these putty will return to the top through the holes of the corner guard, thus achieving the adhesion between the corner guard and the putty we scraped, without the corner guard falling off.
Which parts need to use corner protectors during decoration?
Firstly, let's take a look at the areas where corner protectors are needed for interior decoration. The areas where corner protectors are needed for indoor decoration are as follows: the first position is the corner of the indoor column; The second position is the edge of the indoor return beam; The third location is the edge of the pass where putty needs to be applied. Secondly, let's take a look at which parts need to use PVC corner protectors during outdoor decoration. For outdoor walls or areas that require a right angle shape, PVC corner protectors are required. For example, outside of window openings, outside of pillars, and so on.
