Home improvement construction manual brickwork quality problems

The quality defects often found in Mason's corners:
In the masonry project, there will certainly be a tile touch location, and it is very much, very important. He can directly reflect the masonry master's construction level. Some people think that if you look at the skill of the mason's master, it depends on his touch angle craft. In the home wear, there are many places where the confrontation angles are encountered: the upright corners of the tube, the four corners of the window, the corner of the wall, the entrance position,,,,,,,
What are the quality problems that are easily encountered in the touch angle process, so many masters have not handled it well?
The contact angle is not tight, some gaps are wide, and one can reach into a finger.
The impact angle quickly becomes a pressing brick (not a touch angle, one brick presses another brick).
The touch angle is not a straight line. It is a bit like a dog's leg and it is very curved. The reason for the imperfection:

The vertical position of the woodworkers was not vertical. Workers cut several bricks together, causing the bricks to be of an inappropriate size.
The bricks themselves are not even and the two sides are tight and the middle is not tight.
The cutting of the workers is not in place. In some places, there are many cuts. In some places, the cuts are relatively shallow. When the bricks come together, they cannot be tight.
When laying, there is too much cement mortar and there is too much mortar in the corner to make the two bricks not come together. The reason why the touch angle did not make a straight line:
1. The pillars made by carpenters did not do well, or the original grass roots were too skewed.
2. The magnetic film was too thin to meet the rules of the column. After walking along the column, the tube collapsed.
3, the cutting of the brick is not suitable, it may cause the impact angle is not straight.
The surface of the magnetic sheet is uneven and not vertical:
Why are they uneven and not vertical? The area of ​​the bricks is very small, and the area of ​​a wall is very large. Blocks of bricks are grouped together and checked with a two-meter ruler. It is inevitable that there will be many uneven places. With the vertical detection ruler to detect the verticality within it, but also more or less error. Especially the flatness and verticality of small bricks (small bricks of 10*10) are difficult to control. It is unavoidable to have errors, but the degree of error cannot be too large, and too large an error is a quality defect.
The specific allowable error size is: Surface flatness: 3mm Verticality of facade: 3mm Square of yin and yang Square angle: 3mm What are the consequences of unevenness and non-perpendicularity?
The problem of flatness of the wall: there is a gap in the ceiling. The line of the ceiling is straight, the wall of the magnetic tile is uneven, and there is a gap between the ceiling and the wall. If the ceiling line follows the wall, the ceiling may be flawed.
The facade of the wall is not vertical: at the inside corner of the wall, the size of the bricks above and below the corners of the wall will certainly be different. If the wall is facing outwards: the width of the brick above the inside corner of the wall is narrow and the brick below it is narrow. If the brick next to the wall is a whole brick, then the gap between the top brick and the wall is large; the wall is inclined inward: adjacent to the wall The brick above the inside corner is narrow and the bottom brick is wide.
The wall surface is uneven: there will be irregular gaps between the fixtures, bathroom cabinets, and the countertops and walls of the kitchen cabinets. There will also be gaps between the side panels and the walls.
Preventive measures: Before construction, carefully inspect the wall to see the flatness and verticality of the original grass-roots level. If the error is too great, handle it first and perform a simple leveling. When tiling, fine sand can be blended to thicken the mortar. The thicker layer can be laid, and the flatness and verticality can be adjusted. Walls stretch horizontal and vertical lines. According to the line construction, it will be more orderly. Constantly check with the ruler, found that there is an error, and solve it in time. Can avoid greater quality problems.
The wall tiles are not in one circle, and the joints are staggered:
The four walls of a room form a circle, and the affixed magnetic pieces have the same height and the gap is the same, and the seams can be connected in a circle. Wall tiles are a wall of a wall, posted to the end, should have been a circle, sewing seams to live. However, if the worker’s craft is not well controlled and the bricks are not leveled (the horizontal seams of the tiles are not horizontal) as a whole is slanted to one side, then when they are affixed in a circle, it is not found that they are not joined together and are not in one circle. If there is a position on the wall that is not affixed to the magnetic sheet and the top is connected together, the walls on both sides are only kept horizontal, but the height is inconsistent, and the same cannot be attached.
Solution: When tiling, do a good job horizontally. All four walls are constructed according to the horizontal line, and you can ensure that each wall is horizontal and naturally connect together. If there is no tile in the middle, the first brick on both sides should measure a horizontal line, keeping the height of the first row of bricks the same. Bricks leave a certain gap, there is room for adjustment.
Waist line, tile position is unreasonable, affect the appearance:
The location of the waist line should be: Before tiling, determine the height of the ceiling, the location of the tiles in the end, a wall can not be left and a small, it is difficult to see, to determine the ceiling and the ground, we must determine the waist line The height of the waist line may be in two positions, either the waist line is on the plane with the window sill, or the waist line side is in a plane with the window sill. If the waist line is above or below the window sill and not in a plane with the sill, there is a certain distance from the sill, which is also unsightly. The specific rules for rowing bricks are: to measure the height of the ceiling and the ground, to arrange a few bricks, and then to row down the bricks from the window sill position to where it is, and then stick it up from the height of the second brick. Remember to row down from the slightly higher position of the window sill, because the window sill will also have to be affixed with bricks and a brick, and the window sill will be higher.
The location of the tile: The location of the tile, to consider the specific location of the wall shape, furniture, sanitary ware. That is, after installing a sanitary ware or cabinet, it is obvious that the tiles are affixed to the back of the cabinet or behind the cabinet or in a very inconspicuous position, equal to 100%, which is equivalent to wasting a tile (the tile is expensive). Some people like to place a tile in the bathroom, and many toilets are in a narrow position. This requires the tiles to be as far apart as possible. Tiles are a point of view. If they are not centered, people feel uncomfortable. Therefore: You can't arrange bricks by the ordinary method, and you can't put bricks from one side. You should first determine the location of the tiles and then arrange bricks on both sides.
Mistakes caused by improper bricks:
One of the most important tasks in a mason is to arrange bricks. If the bricks can be lined up, they are half successful.
There are no rows of bricks, and the unsightly projects that result are all the following:
Corridor floor tiles, seams are not centered, bricks are not centered, two bricks, one large, one small, very beautiful.
Paving to a key position, the more prominent place has become a cutting tile, and the cut tile is definitely not a rule. For example, the two types of tiles have different types of tiles, such as a tile or a flower line, and it is a half brick that is connected to this, which is certainly not beautiful.
The bricks were not lined up, no Founder was found, followed by an unimportant and non-straight wall. The result was an important position and the joints of the bricks were found not to be horizontal or vertical. For example, they arrived at the restaurant and connected to the kitchen's door stone. The width of the bricks on both sides of the kitchen door was found to be different, because the large area was not square, and it was too late to catch up. If you wanted to catch it, you would need to relax the gap in some places.
The sill of the kitchen and bathroom was laid straight up from the bottom to the ledge, leaving a small strip, or a small strip on the top.
The bricks below the window sill are not lined up, and the sunken corners on both sides of the window sill are cut into tiles, which is equally difficult to see.
There is also a diagonal paving method. Bricks are not lined up. In the position of the sun corner, it is not a whole brick. It is also very difficult to see.
The height of the bricks is not ranked, resulting in a large gap between the combined areas of the regions. For example: the corridor tiles are higher than the toilet stone; the height of the brick shop is not enough, and the gap between the door and the ground is large; and the ground is higher than the entrance door. The lower threshold of the security door should be low, leaking a gap,,,,,, and the seaming agent is not smooth, full, real:
Grafting agent advantages:
A variety of colors enhance the decorative effect of the tiles and can be consistent with the color of the tiles.
Crack resistance, penetration resistance. Keep the gap clean for a long time.
More sturdy, not easy to drop, not fall off. Frequently occurring quality problems with trochanter:
The jointing time is too early, and the later construction will stain the brick seam again, and it will have to be re-stitched. Waste of work.
Stitching is not true, hollow, with a knife to tie, is a large pit, a little longer, the surface of the grout agent will fall. Therefore, before starting work, the debris in the crevice should be picked up and then scraped with a putty knife.

The joints are not full, and some places are full and some are stuck, which seriously affects the appearance.
Stitching is not smooth, when the seam is wiped, the grout is very rough. Grafting agent construction process:
After the construction is completed, even after cleaning, the surface of the tiles is cleaned and then jointed.
According to the instructions of the jointing agent, watering and mixing are performed.
Clean the brick seams.
Use a spatula to apply the grout to the brick joints. Apply a full, smooth finish.
Wipe the gap with a towel and wipe off the excess caulking agent. (time is within 1 to 2 hours)
After the gap has been wiped, check it again and repair the unqualified area.
Tiles pan out of white things:
After affixing the tiles, after some time, a lot of white things emerged from the cracks in the bricks, a bit like wool. What are these white substances in the tiles?
Answer: Cement Alkaline: Alkali is a common disease on the surface of buildings. According to its different causes and modes of expression, there are various types of flooding, whitening, whitening, blooming, wall and decorative surface erosion. The method is the internal soluble salt and alkali of building materials such as soil, adobe, brick, cement, mortar, concrete, masonry, tiles, and paint that changes with the external environment such as temperature, humidity, etc., and absorbs moisture, moisture migration, moisture evaporation process With the occurrence of physical and chemical changes, a disease phenomenon that destroys the original building materials, the degree of erosion and destruction is also very different. Commonly there are dampness, blistering, pulverization, drumming, emptying, cracking, Flaking, moldy, and crystallization. There may be some reasons why cement basalt may be associated with cement quality, sand, water, air, temperature, and humidity. It is a common problem in buildings. Pebble shapes made of cement are also prone to the above problems: a layer of white surface. If it's a long time, it's okay again.
Solution: Scrape the brick sew and re-strip. Use special grouts that are more resistant to corrosion and less alkaline.
Large area of ​​hollow tiles:
Reasons why bricks are empty:
The newly paved tiles were stepped on and stepped on empty drums.
Some workers have forgotten to get rid of the primordial ash. They just pre-paid it. Such bricks are definitely empty.
Meet false cement, do not freeze, or set too long.
There is dirt on the base and it does not combine with cement mortar.
The base layer or glazed tile is not soaked in water, and the moisture in the cement mortar is quickly absorbed, causing the tile to empty.
Empty drums, the ground has been empty; ground floor heating or water pipes; in fact, no empty drums, but knocked empty.
Empty brick damage:
Touched by hard objects, it is easy to break.
Wall tiles hollow easily fall off.
The floor is hollow, walking easily breaks the bricks, and the furniture may break the bricks.
Empty brick remedies:
The cement slurry is poured, and the cement is leaner. It is poured from the gap in the brick to the empty place under the brick. When the slurry is solidified, the bricks are sticky.
Knock it out and spread it again.
Note: If you change floor tiles, you can use glass suction cups. If you do not use suction cups, it is easy to warp the next brick.
After the construction of the mason, a lot of brick seams are uneven:
Ordinary polished tile paving, if put square, each brick seam will be uniform. If the bricks in the first row of bricks are not squared, the bricks in the back will catch back and cause brick seams to be wide and some bricks will be narrow. Most anti-stalling tiles need to be left. Some need to stay 3mm, big or even 5mm, brick seam is more important. Take care of bricks in both directions. Use the "locator", but you can't rely entirely on the "locator," and make appropriate adjustments based on the size of the bricks. Brick seams are the most prone to errors. Seamless bricks: horizontally seamless, vertical seams. The gaps between the left-hand-sealed ancient bricks and the left and right seams are not uniform. In addition: Paving the wall tiles must also ensure that the facade is vertical. If it is not vertical, the corner tiles of the corner must be of different sizes; either the corners of the corners are approaching, and the vertical seams are widened. The inside corners are beautiful, but the seams are uneven.
Special attention: The seamless brick paving should leave a slight gap out of it, and then the jointing, the effect will come out. Its advantage is: to leave the gap, there is room for the thermal expansion and contraction of the brick; even if the brick is not the rules, the size is inconsistent, there is room for adjustment; horizontal and vertical width of the gap can be consistent.
The worker used a level ruler, but the ground is still uneven:
Tiles, surface level is very important, not only the height of each brick is the same, the four corners are flat, and the level of the entire room should also be the same. There are many workers who are only responsible for the level of bricks and bricks but have neglected the level of the entire room. Seriously, the height of a room can be about 2 cm, which can be seen with the naked eye.
Correct construction: Prior to construction, the horizontal line should be popped up on the wall and paved according to the horizontal line.
Two reference lines:

The developer pops up the horizontal line, and the decoration company's woodwork enters the field also to bomb the wall. To use their line, you should first check it.
Eject your own horizontal line, pop up the horizontal line at a certain height on the wall, or directly pop up the horizontal line at the height of the tiling. Optical line can not guarantee the absolute flatness of the large surface, it is best to stretch a nylon line. There are wall horizontal lines and stretched lines to control, that is, can paste the bricks horizontally, and can also be squared.
Toilet floor water:
Reasons for water retention:
1. When the bathroom floor is tiled, the slope left is small, and the area is still uneven, causing local water in the toilet.
2. The slope of the toilet is sufficient, but due to the installation of the sanitary ware, the water stored due to the blocking of the water flow.
3, floor drain installation location is not suitable, resulting in water leakage near the floor drain. Make up measures:
Partially caused by the ground water, local treatment, the brick-for-brick, raise the bottom of the place, try not to affect the flatness of the ground.
The base of some sanitary fixtures is a concave arc, and water is present inside the concave arc. This is the problem of sanitary fixtures.
The floor drain was installed in the center of a whole brick, and the lowest floor of the floor was on the side of the whole brick, so the water was stored. The whole brick can be divided: According to the four corners of the floor drain to the four corners of the brick, so that the floor drain can be installed at the lowest point. Construction Precautions: Before paving bricks, you should consult with the owner on the slope requirements of the ground: whether the slope to be left is larger (some owners like large slopes and some owners prefer small slopes). Recommended slope: 1 meter low 0.5cm to 1cm. The slope of the ground does not affect the smoothness of the joints between bricks and bricks, that is to say: the entire ground is inclined but the seams of bricks and bricks are flat.
Bad angles, color differences, scratches, and other poor quality projects:
Bad angles: Some bricks would have bad angles, and the bricklayers would not be careful. When they were plastered on the wall, they found out that at this time he was too lazy to change one brick to another. When workers put tiles, they leave no gaps. A few bricks are squeezed together. When another brick is stuck, the brick is squeezed out of the corner. When workers cut bricks, they did not handle the cut surface cleanly and looked like they were fangs. When the worker demolished this brick during maintenance, another brick was knocked off the corner. After construction, no attention was paid to the protection of the finished product. The magnetic piece was caught by a hard object. The brick surface was smashed in a pit or a corner smashed. The bricks are hollow and heavy bricks or pieces of furniture crush the corners. Including the riser, contraction, and deformation of the riser, etc., in the woodworking process, the magnetic plate hits the glazed surface at the location of the impact.
Chromatic aberration: Some bricks are of poor quality and there is a color difference. When the brick was later filled, it was not the same lot and there was a certain color difference. Some bricks, after absorbing water, change color and take a long time to change back. There is also a situation in which the worker's rough construction does not pay attention to the protection of the finished product and causes the glazed tile surface to be contaminated, for example: the oil of the air compressor, the rust of the iron drum,,,,,,,
After the construction, the brick surface was scratched: The shelf leg used by the workers did not provide any protection. The tiles were pulled back and forth to scratch the tile surface. There are some hard objects on the ground (eg, nails, etc.), and the top of the nail is covered with a plate or protective film. When the plate is moved on the top, the bottom nails are also shaken and the surface of the tile is scratched.
The water in the bathroom drains out and soaks the wooden floor:
Reasons: The slope of the bathroom is not very large, the usual bath water is not large, and pay attention, so the water will not flow out. However, sometimes, when the water is turned off at home, the faucet is turned on, and suddenly the water comes again, and the drain is blocked by the hair of the bath or blocked by the washing machine's sewer. No one in the home, the water flow is large. It is easy to go outside and flood the house. After the renovation of the bathroom, the floor drain has been running poorly, or after a period of time, the water flow is not good, and it will easily generate water to drain.
Preventive measures: The gradient of running water should be slightly larger. In this way, even if the water flow is large, it will not flood out. The toilet's passstone is 0.5 to 1 cm higher than the floor tiles inside. This will also not flow out.
Completion inspection: After the mason is completed, use a large bowl of water to splash on the bathroom floor to see if the water flow is slow and see if the toilet floor has water.
Solution: Change the door stone one centimeter higher than the bathroom floor. Make a cofferdam in the shower position and the shower will not allow water to flow outside.
Ground leveling is easy to produce:
Hollowing: The ground is not cloudy, causing the cement mortar moisture to be absorbed quickly. Excessive dirt and dust on the ground. Cement mortar is not connected to the ground. The thickness is not enough: only to level the floor is to match the height of the bedroom with the floor tiles after the wooden floor is laid. Therefore, be sure to determine the thickness of the wood floor before leveling, if there is a height difference of about two centimeters from the floor tile after laying the wooden floor, that is equal to no leveling.
Partial unevenness: In the leveling process, use a long ruler to continuously level off, then use a wooden trowel to smooth out, and finally use an iron trowel to polish. If you do not use a ruler, it is difficult for workers to grasp the flatness of the ground, causing the floor to buzz when it is laid on a wooden floor. Reduce the life of wooden floors. It should also be checked with a long ruler when checking. The flatness should not exceed 3 mm.
The overall level is not: Before leveling, you should make a horizontal line on the wall and level it according to the horizontal line so that you can find a level. Some workers did not make any horizontal lines. Although the grounds looked for were flat, they may be high in one bedroom and low in the other. In the process of leveling it can also be seen that the water flows down, where the water is high, and where it is low.
Destruction of the ground line tube: The ground leveling was only performed after the circuit was modified. Since the electrician did not fix the conduits, and the mason did not care too much, just poured the mortar to the ground. The possible situation was: the ground conduit was moved and was torn open. If you hit solid wood flooring nails on the leveling ground, it is very likely that the pipe will be damaged due to the displacement of the line pipe.
