With the changes in people’s requirements for tile decoration, the types of tiles are increasing, and the requirements for tile laying are also constantly updated. At present, ceramic tile materials such as vitrified tiles and polished tiles have appeared on the market, and their water absorption capacity is low. Strong tile adhesives (adhesive) are used to paste these materials, which can effectively prevent bricks from falling off and hollowing out. How to use strong tile adhesive (adhesive) correctly?

First, the correct use of strong tile adhesive (adhesive)

1. Clean the tiles. Remove all substances, dust, sand, release agents and other substances on the back of the tiles.
2. Brush the back glue. Use a roller or a brush to apply the tile adhesive, and apply the adhesive evenly on the back of the tile, brush evenly, and control the thickness to about 0.5mm. The tile back glue should not be thickly applied, which may easily cause the tiles to fall off.
3. Paste the tiles with tile glue. After the tile adhesive is completely dry, apply the evenly stirred tile adhesive to the back of the tile. The first step of cleaning the back of the tiles is to prepare for the tiles to be laid on the wall in this step.
4. It should be noted that there are substances such as paraffin or white powder on the back of individual tiles, which are the protective layer on the surface of the tiles, and must be cleaned before laying tiles.
5. During the construction process of the tile back glue, try to use a roller to brush, brush from top to bottom, and roll it several times, which can effectively make the tile back glue and the back of the tile fully bond together.
6. When the wall surface or the weather is too dry, you can wet the base surface with water in advance. For the base surface with strong water absorption, you can sprinkle more water. There should be no clear water before laying tiles.

2. The main points of applying strong tile adhesive (adhesive)

1. Before painting and construction, fully stir the tile adhesive, use a roller or a brush to evenly brush the tile adhesive on the back of the tile, paint evenly, and then dry naturally, the general dosage is 8-10㎡/Kg.
2. After the back glue is painted and constructed, it needs to be dried naturally for 1 to 3 hours. In low temperature or humid weather, it is necessary to increase the drying time. Press the adhesive layer with your hands to observe whether the adhesive sticks to your hands. After the adhesive is completely dry, you can proceed to the next process of construction.
3. After the tile adhesive is dry to transparent, then use tile adhesive to lay the tiles. The tiles coated with tile adhesive can effectively bond the base surface.
4. The old base surface needs to remove the dust or putty layer to expose the cement surface or concrete base surface, and then scrape and apply a thin layer of tile adhesive.
5. The tile adhesive is evenly scraped on the base surface, and it can be pasted before the tile adhesive is dry.
6. The tile back glue has strong bonding ability, which is suitable for wet paste base surface, and also suitable for the back treatment of tiles with low water absorption rate, which can effectively improve the bonding strength between tiles and base surface, and effectively solve the problem of hollowing, The phenomenon of shedding.

Question (1): What are the characteristics of tile adhesive?

The so-called tile back glue refers to a layer of emulsion-like glue that we first paint on the back of the tiles before pasting the tiles. Applying adhesive on the back of the tile is mainly to solve the problem of weak bonding of the backboard. Therefore, the back glue of the tile must have the following two characteristics.

Features ①: Tile adhesive should have a high adhesion to the back of the tile. That is to say, the back glue we paint on the back of the tiles must be able to stick tightly to the back of the tiles, and it is not allowed to separate the back glue of the tiles from the back of the tiles. In this way, the proper function of the tile adhesive will be lost.

Feature ②: The tile adhesive should be able to be reliably combined with the pasting material. The so-called tile adhesive should be able to be reliably combined with the tile paste material, which means that after the adhesive we apply is solidified, we can paste it on the adhesive whether we use cement mortar or tile adhesive. In this way, the combination of adhesive backing materials is realized.

Correct use: ①. Before we apply adhesive on the back of the tile, we must clean the back of the tile, and there should be no clear water, and then apply the adhesive on the back. ②. If there is a release agent on the back of the tile, we must also polish the release agent, then clean it, and finally brush the back glue.

Question (2): Why can’t the wall tiles be pasted directly after brushing the back glue?

It is not acceptable to paste directly after the back of the tile is painted with adhesive. Why can’t tiles be pasted directly? This depends on the characteristics of the tile adhesive. Because if we paste the undried tile back glue directly, the following two problems will appear.

Problem ①: The tile adhesive cannot be combined with the back of the tile. Since our tile back glue needs a certain amount of time to solidify, if it is not solidified, it will be directly coated with cement slurry or tile glue, then these painted tile back glue will be separated from the tiles and lost. The meaning of tile adhesive.

Problem ②: The tile adhesive and pasting materials will be mixed together. This is because the tile back glue we painted is not completely dry, and then we directly apply cement slurry or tile adhesive on it. During the application process, the tile tape will be moved and then stirred into the pasting material. On the tiles that cause the tile back glue to stick.

The correct way: ① We use tile back glue, and we must put the tiles painted with back glue aside to dry in advance, and then paste them. ②. Tile adhesive is only an auxiliary measure to paste tiles, so we also need to control the problems of pasting materials and tiles. ③. We also need to pay attention to another point. The reason why the tiles fall off is the base layer of the wall. If the base surface is loose, the base surface must be reinforced first, and the wall or sand-fixing treasure must be applied first. If the base surface is not firm, any material can be used to tile the tile no. Because although the tile adhesive solves the bonding between the tile and the pasting material, it cannot solve the cause of the base layer of the wall.

Note: It is forbidden to paint tile adhesive (adhesive) on the exterior wall and ground, and it is forbidden to paint tile adhesive (adhesive) on water-absorbing bricks
