Why do tiles have to be paved with seams?

Ceramic tiles must be treated when paving, regardless of whether the tiles belong to "seamless bricks" or "round-edged bricks" when paving, they need to be left joints! The main reasons are as follows:

Causes of thermal expansion and contraction. Without this expansion joint, it may be jacked up when it expands and contracts coldly.

When paving construction, find the slope of the gap.

The maximum size of tiles cannot be adapted to the size of a room.

Paving tiles must be treated with seams.

There are three main reasons for this:

1. There is an error in the size of the tile itselfIn the process of ceramic tiles, there will be a certain deviation, the deviation within the allowable range of the national standard is called the error, if there is no seam when paving, some small deviations are superimposed and accumulated, which may affect the straightness of the tile paving, which affects the appearance.

2. There are errors in the craftsmanship of construction workersThe tiles are all manually paved, and even if the same worker is constructing, in the morning and afternoon, in good condition and bad condition, the effect of paving tiles is also different.

3. There is thermal expansion and cold contraction of ceramic tilesWith the change of temperature and humidity, the cement mortar of the tile and the bottom layer will cause a small expansion and expansion, if there is no gap, it will artificially cause the tile to crack or warp and loosen, thereby reducing the service life of the tile.

Floor tiles are not a finished product, so their edges cannot be very precise to ensure that they are smooth and straight. When paving, it is always hoped that the gap left on the whole body is a relatively accurate straight line. Therefore, if there are no gaps when paving, it is very likely that some protrusions do not have room to accommodate, resulting in the overall gap not remaining straight.

Therefore, people always leave a narrow gap when paving, which can accommodate the unevenness of the edge of each brick and ensure the neatness of the whole.

When tiling is laid, a 2-5mm expansion joint should be reserved. 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 addition, the tile also has the phenomenon of thermal expansion and contraction, especially in the north when the temperature difference is larger, it is more likely to appear, if the weather is cold without leaving a seam paving, then it is easy to expand when the weather is hot to cause the tile arching, cracking and other phenomena, in fact, this is not a quality problem, is caused by non-standard paving. Therefore, when tiling and paving, it is necessary to leave enough gaps to allow it to have a certain space for shrinkage and expansion.

Yes, it is needed. Because the tile is relatively fragile, it is inevitable that there will be damage during transportation, so although the decoration is recuted, if there is no seam, it is easy to have uneven joints. In addition, tiles and cement mortar may bulge or crack to a certain extent when they encounter temperature changes.

1.Consequences of leaving no gaps.

The tiles we bought back, the same batch of the same model may have a gap between the angle and the size of the tile, we must have more or less errors in the installation process, and the tile has the phenomenon of thermal expansion and contraction, especially in our north, the temperature difference is relatively large, so the tile will crack and bulge the problem, so we must leave enough gaps when laying the tile, because the tile will have a certain shrinkage space, will not cause the phenomenon of cracking.

2.Gap size.

Many people like to leave no gaps when laying floor tiles, and there will be great misunderstandings without leaving gaps, for example, many people will think that the tiles posted without gaps are relatively beautiful, and the overall look is very smooth and flat, and the visual effect can be called perfect, and there is a lack of very professional knowledge, many people will think that the quality of the tiles is not good, and even think that seamless tiles can completely leave no gaps, and it is easy to leave dust, mold, and difficult to clean up after leaving gaps.

3.How to deal with the gaps in the floor tiles.

After laying the floor tiles, many people will have the same problem, that is, how to deal with the gaps that flow out? Therefore, the gaps we leave must be filled, so that it will look beautiful and atmospheric, and there are currently three kinds of gaps:

1.Cement and putty powder, this method of caulking is not popular at present, because after a period of use, the gap will turn black, and there will be mold in the afternoon for a long time, so it is not recommended for everyone to use. 2.

Caulk is better than the former, because the caulk is added with polymers, as well as trace amounts of antiseptic agents and other main ingredients, this filler can be used on the kitchen balcony because it has a strong stain resistance. 3.The types and colors of the sewing agent are very diverse, we can choose according to the style of our home decoration, and the sewing agent has the effect of anti-corrosion and beautiful appearance, but the price is relatively slightly more expensive.

Hello, tiles must be seamed! In addition to the cold shrinkage and heat expansion of the tile itself, the cement mortar pasted with the tile will also have a certain expansion and contraction with the change of temperature and humidity. If there are no seams, it may cause large areas to arch, fall off, and hollow over time.

Moreover, the ceramic tile is fired from the clay embryo and then paved by the worker, and it is impossible to achieve complete consistency in the specifications of the product, and there will always be errors in the process treatment. If there are no gaps left in the tile, these deviations will be magnified and the tile will not be neat.

Since seam retention is unavoidable, caulking after the fact must be on the agenda. At this stage, the caulking treatment of ceramic tiles is generally divided into two types:

1. Traditional cement caulking.

The traditional method of caulking consists of two materials: white cement and grout.

White cement is white Portland cement, but because of its low adhesion, it cannot replace the role of ordinary cement, and is the earliest ceramic tile caulking material. However, it is easy to mold and turn black in the later stage, and few people are using it now, except for the construction team that only reduces costs.

The grout is equivalent to an upgraded version of white cement, with the addition of modified materials, which greatly improves the waterproofness. The color selection is also richer, and it is currently the most widely used ceramic tile caulking material.

2. New type of sewing agent caulking.

Even if the current grout is high-end, the main material is still cement. Affected by the composition of the cement itself, its waterproof and anti-fouling performance has been very saturated, but mildew is still unavoidable. That's when the sewing agent appeared.

In the early days, the market was a one-component sewing agent, unlike the grout, which is a dry powder mixed with water, it is itself water-based, because it is easy to shrink and collapse to form a V-shaped groove after solidification, and it is basically about to be eliminated.

Now they are upgraded to two-component sewing agents, which are oily, and most of the materials are resin + curing agent, which are formed at one time after solidification, no longer collapsing, with high surface hardness, and waterproof and antifouling characteristics are much better than traditional grouts.

Later, epoxy resin + curing agent material is used, the hardness is particularly high, and the surface is as smooth as porcelain, so the epoxy resin sewing agent on the market is also called porcelain agent, ceramic glue, ceramic clay, real porcelain glue, porcelain seam treasure and so on. Although the names are different, they actually refer to the same thing.

In the sewing agent market, in general, there are no good goods that are cheap, and the truly environmentally friendly, beautiful and durable sewing agents are not cheap. Therefore, when choosing a sewing agent, we must pay attention to choosing a new generation of products, and do not be deceived by the low price of the business.

It is worth noting that the distance between the joints of ceramic tile paving should be the joints of traditional caulk; The beauty sewing agent caulking is required. Therefore, you should choose the caulking method in advance before tile paving.

Our family in Lesman tile purchase, the master is also their recommendation is very professional, he said that the tile should be left joints to avoid due to thermal expansion and contraction, resulting in the formation of bulging or peeling between products. , usually polished tiles are about 3mm, porcelain tiles are 2-5mm, and antique bricks are 5-8mm.

The reason why the owner is reluctant to leave gaps in the tiles.

1.Many owners pave the tile out of the integrity of the good, no gaps can better reflect the aesthetics of the tile, and there is no gap and do not need to do gap treatment;

2.The owner believes that the tile gaps are easy to become black and moldy after caulking, which affects the overall beauty of the tile;

3.The tiling master is paving in order to promote his craftsmanship and recommend the owner to use seamless paving.

Tile laying without leaving a seam can lead to the consequences.

1.Because the ceramic tile and the cement mortar paved have the characteristics of thermal expansion and cold contraction in the later use, the tile paving does not leave a gap, and the later stage will lead to the hollowing of the tile after the expansion between the tiles, and even the phenomenon of tile bulging;

2.The cement mortar layer of tile paving and the expansion of ceramic tiles will cause some tiles to burst;

3.After the tile expands and falls off due to the tile paving without leaving gaps, especially in the bathroom space, once there is sewage and water infiltrating, it is easy to lead to moldy odor;

4.The wall tiles are paved without leaving gaps, which will lead to the risk of the front wall tiles falling off and falling due to the expansion of the tiles.

Specifications for tile paving to leave gaps.

In fact, there is no standard specification for the size of the gap left by the tiles, which is generally determined according to the decoration style of the home and the size of the tiles selected. Reserved 1-3mm gap for general antique style; Small-sized tiles, especially cultural tiles or exterior wall tiles, can also increase the gaps. What's more, the current popularity of caulk has further replaced the use of traditional caulk, and there are no too strict requirements on the specifications of tile joints, generally as long as it is not less than 2mm; For some antique brick series with special three-dimensional patterns on the surface, the gap should not be too small, generally more than 3mm.

1. Ceramic tiles and cement have the characteristics of large thermal expansion and cold contraction, if there is no seam, the ceramic tile will be destroyed with the thermal expansion and cold contraction of cement in use;

2. Because the newly built house will have certain physical changes in the process of use, if there is no joint, it will cause pressure between bricks and bricks, resulting in tile tasting, cracking, and bulging;

3. There is a slight difference in the size of the tile itself. Even if the machine is produced, even if the error has been reduced to the minimum, but there is still more or less error, which is inevitable, only when paving there is a certain gap, can make up for this mistake, to ensure the flatness of the tile.

4. In the process of paving, the error of manual construction is unavoidable, and the effect will be different at different times and under different circumstances, and the seam can ensure the consistency of tile paving.

5. When paving, due to the uneven mixing of the mud, the uneven tensile force generated by the condensation of the mud after construction will also lead to the unevenness of the tile, and the joints can avoid such problems.

6. In the process of paving, leaving joints can avoid the collision between tiles and cause rotten edges.

7. The wall and floor tiles are paved with joints to form regular lines, which can improve the aesthetic effect of the paving, increase the level and texture.

8. Tile joints are convenient for future maintenance and maintenance, such as a tile is accidentally damaged, and it will not affect other tiles when replacing tiles.

9. There will still be very small gaps in seamless paving, and the dirt will be more difficult to clean, so it is the easiest to clean properly and use the sewing agent, and there will be no black stains in the gaps, which will affect the beauty and health.

10. Now the caulk has a variety of varieties, rich colors, good performance, and many selectivity, which is easy to clean and beautiful.

11. Antique bricks must be left with seams, because in order to create an antique effect, the flatness of antique bricks is relatively poor, and the seams can make up for this defect, and can pave the overall effect.

12. Finally, the key point is that if the tile is chipped, cracked, arched, hollowed, falling off and other problems caused by no seams, manufacturers and merchants will not accept it. If the construction party ignores the problem of leaving joints, the construction party bears the losses caused by it. If the owner insists on leaving no seams, the resulting losses will be borne by the owner.

I hope what is written above can help you as a reference suggestion.

x0d x0a due to the production process of ceramic tiles determines that the size of most ceramic tiles has a certain error, if the size of the positive error of the tile does not leave a seam pasted together, next to the tile that encounters a negative size error either left a seam, or is not neat. Therefore, in order to align the masonry joints, it is necessary to leave a joint. There are also some tiles that are actually completely close together, but there are still gaps on the surface.

This type of tile can be paved without seams at all. However, there will be special requirements for the flatness of the masonry surface, the paving process, the characteristics of the adhesive, etc., and the slight deviation can be seen that the masonry surface is uneven, and there will be other problems in the later stage. It is a great test of the technical level of the paving personnel.

The main function is to resist the expansion and contraction requirements caused by the thermal expansion and contraction of ceramic tiles; Prevent the cement mortar of the tile from "anti-alkali" alkali outflow and corrode the tile surface.

1 Thermal expansion and cold contraction, leaving expansion joints!

2 To fill the caulk!

Thermal expansion and cold contraction, of course, you have to leave a little gap.
