Is the tile on the waterproof layer firm or not, what is the key point?

After the renovation of our home, we are probably afraid that this tile will fall off. This also shows that the water absorption rate of many tiles is getting lower and lower, resulting in more and more difficult to paste. So it's really necessary to pay attention to this tile sticking problem.

Now a friend asks such a question: how to stick tiles on the waterproof layer to be reliable? There are many kinds of materials used in the decoration of new houses, how to paste tiles on the waterproof layer to be reliable?

It is the main concern of the decoration owners. The toilet consumes a lot of water, is in a humid state every day, and is also the place where it is used most frequently.

<> then put the back of the tile side up and brush the back of the tile with a layer of adhesive. After mixing the cement slurry, scrape a layer of cement slurry on the adhesive on the back of the tile, and you can stick the tile on the waterproof layer, which will not fall off and will not be hollow. Because the waterproofing layer and the back of the tile are brushed with adhesive.

Many owners are worried that the wall tiles will fall off when they are decorating the bathroom and sticking wall tiles, which is not unreasonable. Because the waterproof layer does not absorb water, the ability to absorb tile adhesive is reduced. In order to prevent the occurrence of wall tiles falling off, we generally take the following ways to solve the problem.

Reserve enough expansion joints when tile paving should reserve two expansion joints. If there is not enough expansion joint, under the action of thermal shock expansion or moisture expansion, stress may occur between adjacent tiles and squeeze each other, resulting in the phenomenon of hollow drum falling off. In order to enhance the bonding strength and prevent the hollowing of the wall tiles for a long time, it is usually done brushing on the waterproof layer or a layer of tile adhesive is applied to the waterproof layer first (Note:

without waiting for the tile glue to solidify), immediately in the paving with sand plaster. (Note that the all-ceramic wall tiles are all paved with tile glue, which is better).

The waterproof layer is also called water avoidance, to prevent water leakage, the general ground flooding height is also particular, the common size on the market is three hundred, what does it mean, that is, the height of waterproof is three hundred mm higher than the ground. Unless it's a wet area, a wet shower may need to be 1.8 or 2 meters, and the rest don't.

The key is to look at the master's craftsmanship, if the master's craftsmanship is good, the tile can be pasted very firmly.

First of all, the most critical place is to see whether there is air in the tile when pasting, and in this case to ensure firmness, the most important thing is to pay attention to the quality and badness of the cement tiled, which is also a very important factor.

The key point is to see whether you have poured some water on the tile and wall when tiling, and when you are tiling, you should paste some adhesive on the back of the tile, so that the sticky tile will be particularly firm.

This mainly depends on whether the empty spots of the tile will be particularly large, and secondly, it also depends on the stability of the tile and whether the edge is carefully fitted.

Whether the tiles on the waterproof layer are firm or not, the most important thing is to see the craftsmanship of the workers, as well as the quality of the cement and the quality of the glue.

How to put tiles on the waterproof layer is reliable? What should I pay attention to? Choose the right waterproof coating; In the decoration of moisture-proof, we have been advocating the matching skills of "wall rigidity and softness".

The pavement is horizontal, like the sunny angle line (the intersection of the wall and pavement), the pipe root and other positions often store water, and it is very easy to have gaps, so it is suitable to choose rigid waterproof raw materials, its tensile strength is stronger, not easy to crack, and the actual effect of moisture-proof is more reliable. However, the wall is not suitable for rigid waterproof raw materials, due to the excessive smoothness of the moisture-proof coating, coupled with the force hazards, it is very easy to cause the floor tile bonding is not strong, and the wall is vertical, the water will take the opportunity to flow down, the hoarding is not large, the moisture-proof regulations are slightly lower, and the flexible waterproof raw materials can completely exceed the regulations.

What to do if a rigid waterproofing layer is carried out; Use raw materials to make a layer of calendering on the moisture-proof layer to improve the roughness level of the waterproof surface of the ground, improve the adhesion, and then reduce the risk of tile hollowing and falling. There are many ways to calender the aqueductor, and the following is a brief introduction to the categories. Choose a plain mortar mixed with appropriate quicklime powder or a cement mortar mixed with appropriate sand, and calender with a brown brush (hard brush).

There is also a way to apply waterproof putty mixed with 425 type fly ash cement, so that calendering can also ensure high compressive strength. Immediately calender the ground waterproofing, that is, brush thicker in the second layer, and then use a hard brush to calender the ground when the waterproofing is not dry.

Note: The calender layer should be delicate, symmetrical, effective in length, generally fluctuating to 3-5mm, and relatively hard, according to the eye observation, the surface of the calender layer will not be cracked, no delamination, so the calendering is excellent. In the end, there is no contradiction between the floor tile parquet and the ground waterproofing itself, just choose the right waterproof membrane and operation method to avoid the problem of tile hollowing down.

The most expensive and effective way is to use tile adhesive. The so-called "tile adhesive" is a finished product that mixes glue and cement in a certain proportion. When using, first wipe the tile glue on the wall, and use a special tool to brush out stripes on the surface.

Finally, place the tiles on the wall and you're done.

First, to prevent the water absorption rate of ceramic tiles from exceeding ** When buying ceramic tiles, you need to focus on checking the water absorption rate of ceramic tiles. Second, to prevent the tile from being too shallow, in order to fit closely with the wall, the tile will be designed with a pattern. 3. The coarser the sand, the higher the strength of the cement mortar, but if the strong is too high, it will also lead to some bad results, such as the ground that is leveled with it will show cracking.

Fourth, the base layer of the tiles needs to be dealt with in order to prevent the hollowing of the tiles, first of all, the wall and ground base of the tile paving must be cleaned. Fifth, the cement mortar needs to be plump and even, and when the prepared cement mortar scrapes the tile against the surface, it should be noted that the cement mortar needs to be plump and even, and no corners can be cut.

The waterproof layer should be pasted with tiles to find a good base, followed by looking for tiles with good water absorption, the quality should be good, and very good paste materials should be used, and ordinary cement mortar should not be used.

You can mix it with water, or you can apply water to the back of the tile, or use water to soak it in advance, so that the tile on the waterproof layer will be more reliable; It should be noted that if the water absorption is relatively low or the waterproof performance is relatively strong to the tile, you can choose tile adhesive sticker.

The wall tiles are not firm, which has a lot to do with the adhesive material. Now there are more vitrified bricks for decoration tiling, but because of its low water absorption, ordinary cement mortar is not enough to bond firmly, and tile adhesive with stronger adhesion must be used to ensure that the vitrified tiles are pasted firmly.

In addition, tile adhesive paste tiles, should be based on different decoration scenes, different materials of tiles, different sizes, different water absorption to choose the right products.

I recommend Meichao Zhan Porcelain Treasure, their products are of good quality, high environmental protection, all products have passed the world's four environmental protection certification of the highest standards, and for different materials (vitrified tiles, glazed tiles), different sizes, different water absorption of ceramic tiles have professional product solutions, perfect adaptation from floor tiles to wall tiles, from the living room to the kitchen and bathroom balcony various decoration scenes, greatly saving time and energy.

If the wall is waterproof, the tile can not be pasted, first of all, the waterproof surface must be scraped off the outer layer of smooth surface, and then the surface is roughened. In this way, when cutting tiles, they can be more firmly pasted.
