Why do floor tiles leak?

First of all, there are four reasons for floor tile seepage:

1. First, waterproof is not in place.

2. Secondly, the water pipe in the wall is damaged, causing water leakage.

3. Also, in rainy days, due to the humid air, water appeared on the surface of ceramic tiles.

4. Finally, the cracks in the tiles are not good and water seepage occurs.

Second, the solution:

1, if there is a problem with the waterproof layer, be sure to remove the tiles, hit the wall to the waterproof layer, and it is best to see the inner wall, then scrape putty, re-do the waterproof layer on the wall, and then lay the tiles. Generally, this method is complicated, so it is recommended to check it.

Secondly, the water pipe is broken, which leads to water seepage. In this case, it is necessary to suppress the water pipe during inspection to see if there is water leakage. If it is really caused by water pipe damage, it is necessary to find out the water leakage immediately and open the wall to replace the water pipe.

3. If it is only the wall seepage caused by moisture, you only need to pay more attention to the ventilation and cleaning of the bathroom in your daily life.

4. If the gap between tiles is not good, water seepage will occur. First, you need to fill the cracks with cement or caulking agent, and then make a waterproof layer.

Tile laying:

1, dry paste method

Paving with tile adhesive is also called dry sticking method, which changes the wet sticking method of mortar cement, and tiles do not need to be soaked in water in advance. As long as the basic conditions of the pavement are good, the working conditions can be greatly improved. Its bonding effect is also better than traditional mortar cement, and it is especially suitable for small and medium-sized projects and home decoration with small working face and unsatisfactory working environment.

2, colorful sealant

Generally used for floors or walls with joints. It has the characteristics of strong color fixation, pressure resistance, wear resistance, non-alkalization, non-shrinkage and non-pulverization, which not only changes the defects of easy falling off and weak bonding of ceramic tiles, but also makes the color of ceramic tiles and the collocation of ceramic tiles appear unified, coordinated and complement each other.

3, a variety of specifications of the combined pavement

Choose a variety of floor tiles with different geometric sizes and lay them in groups according to certain combinations. Because the floor tiles are made up of different sizes and in various ways, the geometric lines of the ground change immediately, which shows changes and vividness in the order.

Problems and detection of empty drum

First of all, we should know how the hollowing is caused, because the moisture content of wall tiles is very high, so this characteristic must be taken into account when pasting. Before tiling, the base should be fully watered and wetted, and the tiles should be soaked in water for at least 20 minutes, and then fully dried in the shade before use. Otherwise, the moisture in the mortar will be quickly absorbed by the dry base and ceramic tile, which will affect its bonding fastness. Wall tiles will absorb water from cement, making cement unable to act as an adhesive, causing dehydration of cement mortar, affecting its setting and hardening, and causing problems such as hollowing and shelling.

After the ceramic tile is dry, tap the surface of the ceramic tile at will with a rubber hammer and tap it everywhere. It is easy to hear whether there is an empty drum below by listening to the sound. It is right to knock a few times.

Distinguish between good and bad:

(1) Ask the distributor for the quality inspection certificate and report of the product.

(2) Carry out visual inspection on site, and observe that the product has obvious quality defects, such as sleeveless, spots, cracks, axle bubbles, ripples, etc. Those with the above defects must not be selected.

(3) Listen to the sound: tap with a hard object, the clearer the sound, the higher the porcelain degree and the better the quality. You can also hold a corner of the tile with your left thumb, forefinger and middle finger and hang it down easily. Tap the middle and lower part of the tile with the index finger of your right hand. If the sound is crisp and pleasant, it is the top grade; if the sound is dull and stagnant, it is the inferior grade.

(4) Drop test: You can drop water on the back of the tile to see the seepage velocity after the water is dispersed. Generally speaking, the slower the water absorption, the greater the density of tiles; On the contrary, the faster the water absorption, the rarer the density and the better the internal quality.

(5) Manual inspection. Pinch two bricks with your fingers and hit each other. The products with crisp and loud voice are qualified products, and the products with low and dull voice must have inherent quality defects.

(6) Distinguish color difference: Because the one-time purchase of wall tiles is relatively large, if there is obvious color difference between multiple packages, the decoration effect will be greatly affected. All packaged products need to be sampled and compared to observe the change of color difference, and the ones with large color difference cannot be selected.

(7) Size: The higher the accuracy of the side length of the tile, the better the effect after paving. Buying high-quality tiles is not only convenient for construction, but also saves working hours and accessories. Measure each piece with a tape measure.

Whether there is a difference between the tile size and the surrounding area, the product with a size error greater than 0.5 mm and a flatness greater than 0. 1 mm not only increases the construction difficulty, but also has a poor effect after decoration, so it cannot be used in the project.
