What are the “hot spots” for ceramic tile laying construction accidents? Tile sun corners are definitely one of them. In this area, improper construction often affects the beauty of the entire wall, and even directly causes the brick corners to break and collapse.
The positive angle of ceramic tiles refers to the outward protruding angle formed by the ceramic tiles during decoration. The outward protruding angle at the joint is a positive angle, and the inward concave angle at the joint is a negative angle. Simply put, the positive angle of a tile is generally the edge formed by the wall tiles.
01 Don’t let the closed corners of ceramic tiles ruin your decoration< /span>
If you have not considered the problem of closing the external corners of the tiles, and have not told the tiling master how to do it, then the tiling master will most likely handle it in the most trouble-free way for the sake of convenience - exposing the bricks on the sides of the tiles. This will look ugly. What's worse is that if the external corner of the ceramic tile is not closed properly, the ceramic tile may collapse or cause the entire ceramic tile to fall off, which poses a serious safety hazard.
Two days ago, Mr. Zhongtao visited a friend's home and saw with his own eyes the "negative teaching material" on how to deal with the problem of closing the external corners of ceramic tiles.
As shown in the picture below, the junction between ceramic tiles is closed in a straight way, and the side tiles are directly exposed, which affects the overall aesthetics of the decoration.
In addition, on the bathroom wall, there are obviously severe chipping and porcelain chipping at the outer corners of several ceramic tiles. These problems are obviously caused by the failure to close the outer corners of the ceramic tiles. Whoever looked at this shook his head and sighed. . This friend told Zhongtaojun: "I usually feel uncomfortable seeing the wall in the bathroom at home. I have to worry about being hit by falling tiles when I go to the toilet. But there is no way. This house is temporarily rented, not by me. I don’t want to spend money to repair my house.”
The way to deal with the external corners of ceramic tiles is relatively complicated. When closing the edges, it is easy to expose the 90-degree angle. If the gaps are not treated well when laying the ceramic tiles, it is easy to trap dirt and inhale water vapor, which will directly affect the mortar layer inside. , resulting in the phenomenon of thermal expansion and contraction, eventually causing the tiles to fall off or collapse. Therefore, during the decoration process, do not ignore the problem of closing the outer corners of ceramic tiles in bathrooms or kitchens.
It can be seen that if the external corners of ceramic tiles are not closed properly, it will not only affect the decorative effect, but also endanger the safety of home life.
In order to avoid the above-mentioned problems in the external corner closing of ceramic tiles and achieve the best decorative effect of ceramic tiles, the two commonly used methods of closing the external corners of ceramic tiles in decoration are Haitang angle and Yang angle.
Now, let’s discuss the definitions, advantages and disadvantages of these two ceramic tile sun corner closing methods.
02 Haitang Point: good decorative effect, difficult construction
Begonia angle is also called "internal chamfering" in the industry, which usually refers to a method of blunting the external angle in architectural decoration or furniture manufacturing. This method of closing the external corners of ceramic tiles is to cut the corners of two perpendicularly intersecting ceramic tiles to 45 degrees, leaving the outermost 2-3mm uncut. After they are put together, they can form a perfect right angle. What I need to remind everyone here is that "Begonia angle" and "45-degree full impact angle" are different. They must be distinguished. Many people easily confuse them.
Through the comparison chart below, everyone will know at a glance.
As can be seen from the cross-sectional structure diagram, after the Begonia angle is processed, there is an extra obtuse angle compared to the 45-degree full impact angle, which makes the corners thicker by 2mm, making it difficult to process, transport and install the tiles. If the porcelain is chipped or the edge is broken, after the seams are processed, the corners will form a rounded arc, which can further prevent collisions.
Because the bump corners are too sharp, not only are they prone to chipping and chipping during processing, but they are also prone to bumps and chipping when moving in later. If there are elderly or children at home who accidentally bump into them, it is even more likely to cause injuries. Compared with the traditional 45-degree full angle, Haitang Angle looks much more beautiful overall. Haitang Angle is more popular in the home decoration industry, but there are still people who insist on using sun angle strips.
The advantages and disadvantages of Haitang Point:
Its advantage is that it has a good decorative effect. Compared with the sun corner strips, the Haitang corner can make the entire sun corner transition more harmonious and beautiful, and the design sense is stronger; if the beautiful seams are selected correctly in the later stage, the overall decoration will be better.The effect will be much better, and there will be no visual sense of abrupt matching.
It has two disadvantages. First, it is difficult to construct. In terms of construction, before the construction of Haitangjiao technology, the tiles need to be cut into a 45-degree angle before being laid. This process is quite troublesome, and inexperienced workers can easily break the edges, and the result may be messy. The gnawing crabapple corners are difficult to align when laying tiles. It is worth mentioning that the Haitangjiao process has certain requirements for ceramic tiles. It is more suitable for all-ceramic tiles and is not suitable for soaked tiles (tiles) because soaked tiles have a low density and are more brittle, and the porcelain will collapse during processing. The probability increases; there are no restrictions on the style and specifications of ceramic tiles, but there are higher requirements for the skill of the tiler.
Second, the cost is relatively high. Using the Haitangjiao process requires processing the tiles in advance before laying them, so it will involve an increase in processing fees. There are generally two channels for ceramic tile processing in Haitangjiao: (1) Machine processing by the ceramic tile seller (manufacturer) factory. (2) Processed on-site by the tiling master. It should be noted that only some ceramic tile merchants on the market currently provide factory processing services. However, if you do not buy enough ceramic tiles, merchants may be unwilling to provide processing services. You should ask this question clearly before buying ceramic tiles. If it is processed by a tiling master, a lump sum price will usually be given based on the different prices in different regions of the country, such as 30-50 yuan/meter (the price here is for reference only).
03 Sun corner strip: low construction difficulty, slightly less beautiful
The so-called sun corner strip, also known as the sun corner closing strip, is a decorative line used to treat the 90-degree convex angle of ceramic tiles, that is, adding a sun corner strip at the intersection of the two bricks at the sun corner of the tile. In this way, the bricks of the two ceramic tiles will not be exposed, and the external corners will have a rounded feel, and the closing effect will be better. On the market, the materials of external corner strips include PVC, aluminum-magnesium alloy, resin, etc.
Advantages and disadvantages of external angle strips:
It has two advantages. First, the construction difficulty is low. The construction operation of the sun angle strip is much easier than the Haitang angle process. On the basis of the sun angleIt can be directly inserted into the closing opening, and there are no big requirements for ceramic tiles. It can be installed with all-ceramic tiles or soaked tiles (ceramic tiles), but the premise is to ensure that the tiles are flat and shapeless. If it is shaped bricks or special-shaped bricks, it is not suitable. The installation of ordinary sun angle strips does not have high requirements on the skills of the tiling master.
Second, the cost is low. There is basically no additional labor cost for tile closing of the corner strips. As for the material cost of the insole strips, the price of a regular insole strip ranges from a few yuan to more than ten yuan depending on the material, which is relatively affordable. Some ceramic tile merchants will even give away the insole strips directly with the tiles to buyers.
The disadvantage is that it is less beautiful. If you use insole strips for decoration, because insole strips are purchased separately, they are generally from different manufacturers than ceramic tiles, and their colors are quite different from the color or material of ceramic tiles. Install the insole strips. When the ceramic tiles are placed at the sun corners, an obvious difference will be formed and the matching will be very abrupt. Of course, you can also choose the material and color of the sun corner strips, and the overall effect will not be too bad after the closing. However, since it cannot be completely integrated, it still feels abrupt when viewed up close, and the overall effect is still worse than that of Haitang Corner.
It is worth noting that there are different opinions in the industry about which one is more durable, Haitang angle or Sun angle strip. Some people think that if the seams of Haitang Jiao are done well and epoxy colored sand with relatively high bonding strength is used, it will be very solid. Compared with the insole strips that will face cracking in the later stage, Haitang Jiao is still more durable.
Some people believe that the most fragile part of ceramic tiles is the corners. If you want to make a crabapple corner, the corners of the ceramic tiles need to be polished. Therefore, the ceramic tiles at the sun corners are even more fragile. If they are slightly bumped, they will easily collapse. situation, and you don’t need to worry about this problem when using external corner strips. The external corner strips can protect the fragile corners of the tiles from being exposed, and they are less likely to fall off. They are much more durable than Haitang corners.
There is also a view that there is not much difference between the two. People who hold this view believe that no matter which method is used, the purpose is to protect the ceramic tiles in the sun corner area, enhance stability, and avoid porcelain collapse. Therefore, there is not much difference in the service life between the two. In addition, they believe that the cleaning difficulty of Haitang Point and Yang Point is actually about the same. If you use a caulking agent for the Haitang corner, it will be easy to clean, but if you use epoxy colored sand, it will bleed, turn yellow and be difficult to clean; while the sun corner strip requires almost no cleaning in the early stage, but it is easy to leave dirt in the gap later, and it is very difficult to clean. Difficult to clean.

To sum up, the two porcelains Haitangjiao and YangjiaoBrick closing methods have their own advantages, and there is no absolute good or bad method. The final choice depends on personal aesthetics and budget. As the saying goes, "What suits you is the best."
