Tips for buying ceramic tiles

Glazed tiles

The so-called glazed tiles are fired with a layer of glazed surface on the surface of the tiles, but because the firing materials are different, they are divided into clay firing and porcelain clay firing. Generally speaking, this smooth glazed brick is easy to clean and maintain, and it is used more frequently on the walls of general kitchens and bathrooms.

1. Which brick is better? Is the lower the water absorption, the better the quality?

Many netizens told me that they choose tiles based on the water absorption rate, because everyone says that the lower the water absorption rate, the better the quality. Is it really Jiangzi? Doubtful, Lao Xie said that strictly speaking, this statement is correct but not comprehensive enough.

Because depending on the location of the tiles, the requirements for the water absorption of the tiles are different. Like floor tiles, the national standard water absorption rate is E≤0.5%. The larger the value, the smaller the density, and the easier it is to penetrate. If it is a wall tile, then the water absorption rate between 10%≤E≤16% is considered to meet the national standard. Because wall tiles need to be laid vertically, a certain degree of adhesion must be required. If the water absorption rate is too low, the pasting is unstable, and the wall tiles are prone to cracking and peeling in the later stage.

2. The price of ceramic tiles is so different, what is the difference? Good or bad are the same, but the cheap ones are not the same and usable!

Lao Xie said that now the ceramic tile store will prepare a variety of model rooms, and the effect will look the same after the paving is completed! (Of course I mean tiles with similar prices. If you have to compare ordinary tiles with big brands like M, fools know the expensive ones!) So Lao Xie taught simple tricks to distinguish good tiles from bad ones. .

One touch, two knock, three look to easily identify good and bad tiles. Lao Xie said that because the back of the hand is a more sensitive part of the body, it is more intuitive to feel the surface of the tile with the back of the hand. The better the quality of the tile, the better the surface finish, not rough at all, and feels as slippery as an egg~ But if you are to identify the following type of climbing wall tiles, you will not use the back of your hand, but use your little finger to feel the middle The gap, the better the quality, the smoother the hand feel, without any sense of blocking. (Of course this is for floor climbing bricks imitating small square bricks. This method is not suitable for old tiles.)

Full body brick

Full body brick is actually a A kind of porcelain tiles that do not need to be glazed. The non-slip and wear-resistant tiles we often say refer to the whole body tiles. Polished tiles and vitrified tiles are all types of bricks. The impact resistance of vitrified tiles is quite good, and there is no need to worry about a pit when a hard object falls and cuts. The disadvantage is that the pattern is too limited.


oh, I forgot to mention the mosaic. This kind of brick is quite small, hard, wear-resistant, acid-resistant, and not easy to break. And because of its rich colors, it creates a strong sense of hierarchy. Generally used in small kitchens and bathrooms. The purchase aspect is much simpler than the previous two bricks, which is simply to look at the style and the flatness of the cutting surface.

After touching the surface, I will knock again, not directly with a hard object, but knocking on the knuckles. If the sound you hear is quite crisp and the echo is particularly loud, this is definitely a good brick. If you hear a muffled noise, it means that the low-density tiles have a poor firing effect and are prone to back leakage, which is a poor quality tile.

One step is to see, this step is not common to all bricks, mainly for bright bricks.

Look at the reflective mirroring of the surface, the higher the finish, the clearer the lines on the surface of the tile, the clearer the mirroring, and the less likely to be deformed. (If it is an imitation version, then the image of the shadow on the tile will be blurred, and the lines will be deformed. Because the imitation version is just a starting version and cannot be reproduced.)

Look at the ceramic tile body. On the side of the tile, the more muddy the color of the embryo body, the worse the quality, indicating that there is a lot of muck in the middle. A good brick body is fired from natural ore, and the color is close to white. Look at whether there are black spots in the middle. The more black spots, it means that the firing time or temperature is not enough, and it is caused by insufficient oxidation. This kind of brick is equivalent to sandwiching raw rice, which is unripe. Once on the wall, it is easy to crack and fall off.

Look at the back of the tile. When choosing a tile, you should pay special attention to whether the pattern on the back is the same. This will directly affect the post-collage. It is recommended to choose the original batch of production. Or buy it in a store.

3. How to do the water test? Can you judge the permeability of the tiles?

Everyone knows that ceramic tiles have a certain water absorption rate, so to judge its permeability, the first thing that comes to mind is the water test. But in fact, this experiment is not completely scientific. If the wax drops on the back of the tile, it will still not penetrate. So what we observed in this experiment is not whether the back of the tiles can absorb water, but that there is no watermark on the front of the tiles.

4. How to choose the earth tiles? Any recommendations?

For working-class people who don’t have time to clean at ordinary times, bleed tiles are a good choice. They are cheap and easy to clean.

This kind of whole body brick with one color and no grading layer is the cheapest of the vitrified bricks, which belongs to the obsolete brick (but all babies born in 80 know that this is the old house in the past. A kind of brick that I love to use for decoration) Now I buy this kind of bricks for old or rented houses. I usually don't choose this kind of brick for my own home.

For those who have requirements for quality life, if you choose vitrified tiles, it is recommended to choose full polished glaze, microcrystalline stone, and imitation jade texture, which has more room for pattern selection. (Although these patterns are hard to see where they can be cut, at least the price/performance ratio is relatively high.)
