For these corners of the wall, if they are not handled well, curves will appear later, which is very ugly. At the present stage, the most commonly used treatment for positive corners is PVC corner protectors, so how to use PVC corner protectors?

What is PVC corner bead
PVC corner bead is made of PVC plastic material, a kind of material used to protect the wall corner construction. From the appearance, the PVC corner protector is an L-shaped line. The sides of the corner strip are perforated, and the faces are perpendicular to each other, forming a right angle of 90 degrees.
The part where the PVC corner protector acts is the positive corner on the wall. For example, the corner of the wall, the corner of the pillar, etc. The function of the corner protector is to protect these corners and facilitate the shaping of the last batch of these corners by scraping putty, which can achieve a perfect 90-degree right angle. This is very beautiful from the appearance, and very conducive to stereotypes.
How to paste PVC corner bead
The first step is to put a thin layer of putty on the positive corner of the corner protector. The role of the putty is to facilitate us to paste the corner protector on the male corner. After scraping the bottom layer of putty, you can then buckle the corner protector on the male corner, so that the corner protector sticks to the male corner. .
The second step is to batch putty. After fixing the corner bead, we can scrape the putty. At this time, generally speaking, it is the first putty scraped, that is, the bottom putty. When the bottom putty is scraped, the entire corner protection strip must be covered, so that the specific function of the corner protection strip is realized.
The third step is to scrape the putty a second time. After the first putty has reached its full strength, it is basically more than seven days. We can now scrape the second putty. Here putty can roughly level and close the entire wall, and finally make a beautiful sunny corner.
Why can the corner bead stick to the sun angle

This corner strip has a total of two faces, and the faces are perpendicular to each other. The most important point is that both sides of the hole are punched. The diameter of the hole is about 10mmmm, and the distance between the hole and the hole is about 5mm.
The second point we look at why the corner bead can be pasted on the sun angle. The above introduced to everyone that when we paste the corner protector, we first scrape a layer of putty on the wall. The specific position is the position where the corner protector is pasted, and then we can press the corner protector to scrape the putty. position. At this time, you can find that these putty will return to the top through the hole of the corner protector, so that the corner protector sticks to the putty we scraped, and the corner protector will not fall off.
