What are the requirements when laying floor tiles wetly? How to plaster the back of the tile?

The floor tiles need to be soaked in water for a period of time, and the wet floor tiles are generally smoothed and pasted directly with ordinary cement mortar.

At this time, the biggest requirement is that the floor of the paving tile must be very flat, so that it can be paved very perfectly, there will be no gaps, and the back should be plastered very thick, so that the tiles can be paved very strong.

First of all, it is necessary to do a good job of corresponding protective measures, thermal expansion and cold contraction measures to prevent gaps after drying, and secondly, to add mud locally when paving, because of the consideration of the overall balance problem, it is necessary to pay attention to.

There are two ways to lay floor tiles, one is dry paving, and the other is wet paving, and when building self-built houses in rural areas, the method of wet paving is generally used, which is a more common decoration method. What is the difference between dry and wet floor tiles? If you want to know more, let's take a look.

First, the process of wet paving of floor tiles.

1. First of all, the ground needs to be treated, the surface should be cleaned, and the flatness should also reach a certain standard, so as to ensure that the ground does not have any debris or dirt, and is in a clean state. Moreover, it is necessary to soak the floor tiles in advance and dry them in the shade so that there are no water stains on the surface.

2. Stirring mortar as a binder material, wait until the ground is clean, lay the horizontal line according to the design requirements, and then stir the mortar according to a certain proportion. Generally speaking, cement and sand should be prepared, and the ratio is generally 1:3, and then add water and stir into a paste, remember to be even.

3. Check whether the texture and size of the floor tiles are correct, and then cut them according to the needs, and then water and moisten the ground, and then coat the back of the floor tiles with cement mortar, and directly pave them on the ground.

4. Gently tap with rubber glue to remove excess mortar and air. When laying the mat, you should also pay attention to keep it flat, and at the same time remove the mortar from the excess pants, wait for a day or two, and then treat the gap after it is dry, and maintain it, so that the effect is better.

Second, the difference between dry and wet floor tiles.

1. If you choose dry paving, the mortar and moisture used will be relatively small, and there will be no blistering problem and no hollowing. However, if the method of wet paving is adopted, because there is more moisture, it is easy to have the problem of hollowing in the later stage.

2. If dry paving is used, the effect will be better, because the flatness is better, but the wet paving has more moisture, and it is easy to appear that the tile slides, which is difficult to grasp.

3. If you choose dry paving, the ground needs to be treated before, and the requirements are relatively high, if you don't add water, the paste is not firm. If the method of wet paving is adopted, the requirements are relatively low.

Summary: If you need to lay floor tiles at home, you can choose dry or wet according to actual needs. If it is wet paved, it is necessary to follow certain steps to ensure that the effect of paving bricks can be idealized.

1. Check whether the base treatment of the ground is qualified, such as sanding, hollow drum delamination and other problems on the ground, and then pave the tiles after treatment;

2. Before the ground paving, the elevation line of the ground finishing layer construction should be elasticated on the wall to maintain the unity and coordination of the floor tile surface layer and the height of the finishing layer of other spaces;

3. Before using cement mortar to pave the floor tiles, the dry ground should be sprinkled with water to prevent the dry ground from absorbing the moisture in the cement mortar too quickly, resulting in the tile paving hollow drum delamination.

4. The selection of cement and sand should meet the requirements, and the ratio should meet the requirements, if the proportion of cement and sand is mixed is improper, the improper selection of cement and sand will have an impact on the construction quality, and the cement should be made of ordinary Portland cement with a strength of megapascals, and the sand is in the river sand.

5. Pay attention to the flatness of the paving at any time during the process of paving; Wipe off the cement mortar that overflows the brick joints in time;

6. The tile should not be stepped on on the brick surface before drying, and it should not be hooked before drying;

7. After the tile is paved, the paving quality inspection is carried out after it is dried and solidified, and the focus is on checking whether there is a problem of hollowing and delamination.

In fact, these things, just leave it to the decoration master to be responsible, you only need to be responsible for acceptance, usually the following problems will occur when paving floor tiles, just pay attention to it.

1. Plate hollowing: the base layer is not cleaned, the sprinkling is unevenly wet, the bricks are not encroached on, the area of the cement slurry combined with the brush is too large, and it plays an isolation role after air drying.

2. The surface of the plate is not clean: mainly after the layer is done, the protection of the finished product is not enough, the paint bucket is placed on the floor tile, the mortar is mixed on the floor tile, and the grout is not covered when brushing, etc., all cause layer pollution.

3. Inverted slope of the room with floor drain: when making the screed mortar, there is no elastic line slope according to the flooding slope required by the design. Therefore, it is necessary to find the elevation, find the slope when playing the line, and wipe out the flashing when plastering the cake and the standard bar.

There are two kinds of paving methods for paving tiles, one is wet ash paving, the other is dry ash paving, dry paving is more troublesome, wet paving is easier, but wet ash paving is easy to empty, and the adhesion is not as good as dry paving, wet paving is only suitable for relatively small floor tiles, paving 600x600 are reluctantly, and more than 600 are dry paving.

The paving method of wet paving is to mix sand cement into cement mortar, directly sticky, to see the quality of the floor tile paving is to see the flatness, knock to see whether the drum is empty, to see whether the wrong joint, to see the size of the gap is uniform, the paving method of dry paving is:

1. Mixing cement mortar: according to the ratio of 3:1 (3 parts of sand and 1 part of cement), mix the sand and cement evenly, mix it with water into a semi-dry state, that is, grab it into a ball by hand.

2. Remove the floating sand and debris on the ground, and water it to moisten, and do not have stagnant water.

The dry hard cement mortar that is evenly stirred is evenly spread on the damp base layer, paved according to the horizontal line, poured, and smeared with plain cement slurry, and the surface bricks can be placed solid and leveled.

3. Put the bricks on the mortar and press the line with a rubber hammer to vibrate, and after removing the bricks, smear a thin layer of pure cement plaster on the back of the bricks and smash it.

This kind of paving method is better, more strong, and the flatness is good to grasp the reason is that the semi-dry ash does not shrink, and the work is also beautiful, what kind of smashing is what, and the adhesion is relatively strong, and now the decoration mostly adopts the dry paving method.

Now the construction technology of dry paving is adopted, that is, more cement and yellow sand, the floor tiles are not easy to break, and the flatness is also good.

Wet paving is directly pasted with cement slurry to paste the floor tiles, and the cement composition will break the floor tiles, and this process will no longer be used to pave the floor tiles 10 years ago.

Dry paving is better, and dry paving is not easy to produce hollow drums.

You need to look at where this question is. Generally speaking, the wet paving method means that the ground is leveled with mortar or fine stone concrete according to the set horizontal height, and then the plain cement slurry is applied to the ground behind the tiles; Dry paving method refers to the use of a certain proportion of cement yellow sand, add a small amount of water after stirring to become dry material, according to a certain horizontal height of paving, ceramic tile on a batch of cement slurry, together with the dry material together to apply pressure down to flat.

The advantages of the wet paving method are high compactness and good adhesion to the ground. However, it is not easy to lay flat, and it is generally only used in the bathroom, or balcony and other sloped positions to use this method to pave; The advantages of the dry paving method are that the flatness is high, the speed of paving is relatively fast, and the firmness is also very good. Generally, the living room, kitchen and other parts are paved with this method, and the effect is very good.

The method of wet shop is good, and my family uses wet shop.

Dry paving methodIn short, the cement mortar used is relatively dry, generally using 1:3 dry cement mortar, according to the horizontal line to explore the smoothing, put the tiles on the mortar with a rubber hammer to vibrate, remove the ground tiles and pour the cement slurry, and then put the ground tiles on the ground to vibrate flat.

The dry paving method is mainly used in dry floors such as living rooms and bedrooms. Due to the unevenness of the ground base and the requirements of the thickness of the ground pavement, the general ground will use dry ash into the car blind cushion, and then wipe a layer of cement slurry on the back of the floor tiles.

Because the cement mortar laid on the ground by the dry paving method is relatively thick, the thickness that needs to be laid will be marked first, and the cement mortar of different thicknesses will be automatically leveled according to the corresponding error for uneven places, so there is no need to level the ground separately.

Ordinary cement yellow sand is cheaper than tile adhesive in the price closed space, but the dry paving method is more labor-intensive and has high technical content. However, the dry paving method cannot be applied to wall tiles.

Wet paving method: The cement mortar used is relatively wet, and the cement mortar is evenly smeared on the back of the floor tiles and the ground, and the tiles are directly pasted on the ground. This is now known as the thin pasting method.

The wet paving method is recommended to be used in kitchens, bathrooms and other areas that need to be waterproofed, and they need to be soaked in water in advance, so that the tiles with water absorption rate will not quickly absorb the moisture in the cement layer, so that the cement will lose its corresponding properties.

Theoretically, the tiles should be soaked for more than 2 years, but in practice, the owner only needs to see that the tiles soaked in water do not bubble. When paving, a thin layer is scraped on the ground and the back of the tile, and if the leveling is not carried out in advance, it cannot be automatically leveled when the tile is paved, so it needs to be leveled.

The ** of tile adhesive is higher than that of ordinary cement mortar, but the wet paving method is more time-saving and labor-saving, simple and convenient, and can be attached to wall tiles and floor tiles.

Wet-laid floor Zen liquid royal brick is a commonly used way to lay ground materials, compared with dry paving, can better ensure the paving effect, but also can effectively prevent ground cracks and hollowing. The following is a specific method for wet-laying floor tiles.

Step 1: Preparation.

1.Check the flatness and humidity of the ground: Before paving, you need to check the flatness and humidity of the ground. The ground must be flat and moderately humid, otherwise it will affect the paving effect.

2.Prepare tools and materials: The tools and materials that need to be prepared include tile cutters, levels, spatulas, tile glue, tile cross joints, rubber hammers, fine soft brushes, waterproofing agents, etc.

Step 2: Determine the direction of paving.

The paving direction can be determined according to the layout and functional requirements of the room. In general, the floor tiles should be paved in the direction of the main light, which can make the room look more spacious.

Step 3: Apply the glue.

Apply the tile glue to the ground, and the one-time application area should not be too large, so as not to cause the glue to dry out for too long. After applying the glue, you can use a tile cross joint to leave a gap to facilitate the circulation and exhaust between the tiles.

Step 4: Lay the tiles.

Lay the tiles one by one on top of the glue. Use a rubber hammer to hit the tiles to make sure they are flat. If adjustments are required, the paving position can be gently adjusted with a fine, soft brush or wooden stick. The tiles paved on the same line as He Yan should be kept stable, and the gaps should be consistent.

Step 5: Tile cutting.

When the tile that needs to be attached to the edge is not the right size, you can use a tile cutter to cut it to the right size.

Step 6: Caulking and waterproofing.

After the paving is completed, it needs to be treated with a waterproofing agent. After waiting for a while, the glue in the crevices will undergo a hydration reaction and turn into hard glue. The glue seam needs to be scraped flat with a spatula and filled.

When the caulk is completely dry, the surface can be wiped with a rag to make the floor tiles completely clean, smooth, and tidy.

In conclusion, wet floor tiles are an important and tedious task that requires meticulous paving planning and practical skills. Only the professional cement brick paving method can provide a good foundation for the house to meet people's pursuit of a better life.
