What are you most annoyed about after buying ceramic tiles to decorate your house? First of all, it can't be the price of ceramic tiles, so what will it be? Mr. Tao Zhong said that the most annoying thing is that the ceramic tiles are unevenly laid. Many people will say that even though the ceramic tiles are expensive, they are not evenly laid, so many people will be very angry, which will lead to What are the reasons why ceramic tiles are unevenly laid Do you know? Then let’s follow Zhongtao Jun to find out more!
When it comes to who caused it, many people will say that there are only two answers: either the quality of the ceramic tiles is not good, or it is caused by the lack of skills of the decoration master. So who should be blamed? In fact, there are quite a few such factors, mainly caused by two major factors, namely paving factors and environmental factors.
1. Paving factors
1. The paving direction is wrong
Under normal circumstances, there will be a special brand logo and direction mark on the bottom of the ceramic tile. The direction mark can indicate the direction of the ceramic tile when the plasterer is laying it. Paving according to the direction marks can make the surface texture of the ceramic tiles more smoothly connected and ensure that the edges of each tile have a similar degree of warping and the paving will be relatively smooth.
Many home improvement bricklayers ignore the direction signs and do not lay in the direction indicated by the arrows, which easily results in uneven seams at the corners.
2. The brick joints are too thin
Almost every tile has slight deviations in length, squareness, edge straightness, etc. If no seams are left, when the height difference between the edges of the tiles is slightly larger, the seams will appear visually uneven.
Seamless paving can also easily cause the tiles to bulge and arch when they expand due to thermal expansion and contraction, and even crack in severe cases.
3. The tiles were not hammered down after laying them
After the tiles are attached to the ground, since the cement mortar is still in a semi-dry state, it is necessary to tap the mortar and press it down to make the cement mortar evenly distributed under the tiles. This can avoid uneven stress on the tiles when the cement solidifies, affecting the flatness. Many times the paving workers ignore this step and fail to knock the bricks firmly.
4. The proportion of cement mortar is wrong
Traditional paving generally uses cement and sand mixed on site as an adhesive, and the proportion of cement and sand is very important. The ratio is wrong, the proportion of sand is too high, or no adhesive is added to the mortar, the cement mortar will not stick to the tiles and the floor tiles will become warped.
5. The cement mortar is not evenly applied
When laying ceramic tiles, the cement mortar on the back needs to be applied evenly and fully. In order to save time, some bricklayers only apply mortar around the tiles, resulting in only 3 to 5 centimeters of mortar on the edge of the tiles sticking to the wall. Ceramics with uneven stress may also appear uneven later.
6. No need for levels and vertical cones
The workers' laying process of tiles was not standardized, and they did not use a level and a vertical cone for positioning, resulting in an uneven paving effect.
2. Environmental factors
1. The temperature difference is too large
If the temperature in the north is too low, the moisture in the cement mortar binder will freeze, causing volume expansion and stress, thereby destroying the structure and strength of the cement mortar. If this happens, the tiles will not be well combined with the floor, and the cement hydration heat will be concentrated under the tiles, causing the tiles to bulge.
High temperatures can also cause ceramic tiles to deform. Floor tiles that use geothermal heating are prone to deformation when exposed to high temperatures for a long time.
2. House lifting
The building itself will undergo a certain degree of settlement due to geological problems. The degree of settlement is different at different locations, and the ground will also be uneven.
3. Do the following when laying bricks
1. Test the flatness when purchasing ceramic tiles
Generally, the flatness of ceramic tiles is mainly measured with vernier calipers, but in daily life, we can put two bricks together and stand them up to see if there are any gaps between the two bricks. If there are obvious gaps, it means that the flatness of the brick is not very good.
2. On-site supervision
Since the flatness of the tiles cannot be guaranteed, it is necessary to supervise the work in real time and raise questions in time if something is wrong. You need to be more cautious when choosing guerrillas for decoration. Some bricklayers are not responsible enough. In order to keep up with the progress, they will not remind the owner or pick bricks specifically.
It is best to understand some basic paving knowledge yourself or find a professional supervisor, so that if problems are found, they can be dealt with in a timely mannersolve. During acceptance, pay attention to check the flatness of the hollow drum and the joints.
So, after reading the above content, you have a certain understanding of The reasons why the ceramic tiles are unevenly laid. So for what I said before, should you blame the ceramic tiles or the decorator? I believe that Mr. Zhongtao doesn’t need to say the answer. You already know it in your heart. You can’t blame them for this. Okay, that’s what Zhongtaojun shared with you today, go ahead!
