1. Q: I'm preparing to decorate the kitchen living room floor with black Chinese furniture. The furniture cabinets are black and white. The whole house feels a strong contrasting black and white tone. I don't know what, what about China's black radiation?

Answer: Chinese black is a granite stone and can be used as a cooktop.
3, Q:
My toilet pipes are buried in dark pipes. Now the construction unit says that the aluminum pipes made of Rifeng are good, green and non-toxic, and the service life is longer than that of galvanized pipes. Because there is no rust, there will be no secondary pollution of water quality. Now There is a tendency to completely replace galvanized pipes; supervisors say that the wall strength of aluminum-plastic pipes is not as good as that of galvanized pipes, so a joint must be provided every 1.2 meters, and normal galvanized pipes should be used. Who is right in the end? Whose program should I use? In addition, the price of construction materials for construction contractors is 40 yuan per meter for galvanized pipe buried pipes, and 80 yuan per meter for sunburst aluminum plastic pipe buried pipes, a price difference of two times. It is because aluminum plastic pipes are much more expensive. However, the supervisor said that the prices of aluminum-plastic pipes and galvanized pipes are almost the same. Who is this right? Or, I should use Nisshin aluminum plastic pipe, but asked myself to buy water pipes, so as not to be cheated in price and quality?
answer:
1) The strength of the pipe wall of the aluminum plastic pipe has already met the need, and it does not need to care about who is weak or weak.
2) The galvanized iron pipes often contain trachoma, and there are hidden dangers of burst pipes. Therefore, builders basically do not dare to cover dark pipes with galvanized iron pipes. If you use a dark pipe and use galvanized iron pipe, it is a risky behavior.
3) The practice of installing a joint every 1.2 meters is an act of idiot. You asked if your supervisor did any work. The more connectors, the higher the hidden danger! Therefore, unless the director is not enough to connect or turn, there is no need to add more joints.
4) The price difference between aluminum-plastic pipes and galvanized steel pipes is very large. It is possible to double the price of the pipe part, and the single connector is 5 times worse. However, the price of aluminum plastic pipe can be appropriately reduced.
In simple terms, your supervisor is basically a layman, suggesting that you immediately fire him.

Answer: After installing the light steel gypsum structure, the ash will be directly applied.
After the installation of the benzene board, one more batch of cement is required to be approved for hot, and then the ash shall be approved. The surface of the light steel gypsum structure is gypsum board, and cracks may be cracked when the joints are handled improperly. It is generally difficult for the benzene board to crack with cement. Light steel gypsum construction is quick and ready to use. The benzene board needs a certain process and time. The middle of light steel gypsum is soundproofed cotton, and the middle of benzene board is foam. Both are light materials. The former is better than the latter if it is equipped with soundproof cotton, and the latter is the latter if there is no soundproof cotton in the former.

10, I need to make two partitions in the room, the requirements are better sound insulation, do not know how to do, is the use of cement board or plasterboard, is it necessary to add noise barriers?
A: You can use light steel keel gypsum board, add noise insulation cotton.
11. Yesterday, I met with the decorating company again. I saw a large list of their lists. The scalp was a bit numb. First pick the skirtings, doors and windows sets that you think are more important. They are made of MDF with three plywood and solid wood lines. Why not use solid wood to kick the feet and solid wood lines? They say it is easy to deform! Is this true?
Answer: The installation of solid wood is not easy to handle because it does not have a bottom plate and is not well fixed to the wall surface. It is easily deformed. The practice of using plywood is relatively firm and not easily deformed. 12. How can I make the upstairs waterproof layer in the kitchen and balcony?
A: First of all, through friendly consultations, we will explain the principle of waterproofing. This is good for everyone. If it does not work, look for the management office again. If you can't do it again, you can only complain to each other.

A: White.
14. Can I spray white paint on the wooden door I bought? If you spray white it will not turn yellow...

15. The gas company requires that the gas pipeline be closed. Is there any good solution?
A: If you are in Shenzhen, you can use blinds to close the door as long as you can ensure that the gas leaks out in time. Because the accumulation of gas power in the event of an open flame can cause an explosion.
16. In the past few days, my house was renovated and it was a little troublesome. The original plan was to use plastic steel doors. Who knows good materials should be worth more than one thousand yuan/party, a total of about 3,000 yuan, which is too extravagant. Some local companies do 300 yuan / party, hardware accessories are poor, get I do not know what to do? Can you recommend good quality and affordable products in Guangzhou? In addition, the decoration team then suggested that I change the wooden door. He said that as long as 1100 yuan, I will use the best imported materials. I would like to ask you, if the bathroom door with wooden doors, how to do a good moisture, the door of the rails, pulleys with which The imported branded products can be muted and durable.
Answer: In fact, it is entirely possible to use thick PVC doors, and as many as 300 yuan each time. As long as it is a thick PVC, it is generally difficult to deform. Of course, there is a thin PVC door on the market, only more than 100 yuan, it is easy to deformation and damage.
17. Visited the shop today and seriously watched the Nobel, the champion, and some less famous brands of tiles, and found that the price gap was too great. Such as Nobel's at least 90,100, and less well-known brand offer only 30,40. I took a close look at the level of color and peace and I felt that it was good. I really do not understand why the price difference is so far away?
Can it be cheap? Ha ha.
A: The composition of prices is various. Including the manufacturing costs, administrative expenses, advertising expenses, sales profits, distributors and other aspects of the division. Price is a performance factor than reference, but not an absolute factor in performance. 18. Will the bathroom and kitchen cover wooden door covers? Will it be deformed by moisture?

19. I heard that the solvent of the nitrocellulose lacquer evaporates quickly. The wooden lacquer coated with the nitrocellulose lacquer seldom produces harmful gases after being left for a while, but the nitrocellulose lacquer is prone to produce small cracks when exposed to ultraviolet rays (sunshine). Is it this way?
A: No. Generally speaking, as long as the construction is conducted according to the specifications, nitrocellulose paint is a good choice because it will not turn yellow. Of course, if you use the sun for a long time, no matter what paint may be cracked.
20. Is the quality of seamless tiles very good?
In the past, we may have heard about seamless steel pipes. Nowadays, the hype of some seamless tiles is purely tricky, and consumers need to pay attention. Aside from the decoration, we do not know from the physical point of view. This is theoretically unacceptable:
The expansion of the seamless steel pipe is overall 360 degrees outward, so no cracks will appear. Most of the tiles are constructed in a relatively closed space. Taking the wall as an example, generally, the left and right sides and the lower part must be closed with a fixed wall and the floor. If the tiles are processed seamlessly during construction, they expand there when they are expanded. What?
Obviously, one of the prerequisites for the realization of a seamless tile is that the thermal expansion and contraction rate of the tile is zero. We know that this possibility is zero.
What are the consequences of forced seamless processing? It is impossible for a tile to expand or contract due to thermal expansion or contraction, because the adhesive strength on the back cannot be greater than the force pushing the wall. The result is only the same: the tiles arch.
31. Will the 60*60 polished tiles be used in the living room?
Answer: At least 3cm.
32. The owner’s balcony has been sealed with aluminum alloy. Now I would like to install a double window. What material should I use? How to construct it?

34. I purchased the top-of-the-building housing, sent top roof rooftops (the so-called sky gardens), and shared a 90-square-meter long square roof with a door to the door. Because my head and the head of the house were good colleagues, the two decided to jointly develop the Hanging Garden. Imagine the following: plant a row of spring flowers on the west side and let the leaves grow long enough to block the sun from the room in the west. Dongtou builds a grape rack. Spread some turf in the middle, plant some flowers and plants, use pebbles to lay out some trails, and put a cast iron hanging chair. problem:
1) Is this solution feasible?
2) Next to the spring flowers of Xitou, I wanted to get a row of white wooden fences, but I don't know if the wood could survive the storm. What should I do?
3) How thick soil should be under the turf to ensure turf survival? I heard that the turf is very expensive. Which kind of turf is easy to survive and easy to care for?
4) Can a cast iron chair be weathered (no rust)? Do you need a shelter?
Answer: 1) The grass should be replaced with a turf carpet, otherwise it is easy to breed insects or overload the floor. Others are feasible.
2) The white wooden fence can only be painted regularly. Or use stainless steel to spray the white metal paint and make it durable.
3) Same as 1)
4) Cast iron generally needs to be treated with rust prevention first, and the sitting part can be made of wood, which is generally not easy to rust. As for the pavilion, it was decided on its own.

37, had a small building can be a big smile, but the kitchen fumes issue scratching their heads. It is good to use a fan or a range hood. Or what smokeless stove is good. If the smokeless stove is good, what kind of structure is it? Thank you A: As the name suggests, of course, you have to use a range hood. The exhaust fans are used for ventilation and can also be installed, but they cannot replace the hood.
38. Many security doors are now framed by two doors, plus wooden doors are very wordy. Even if you open three doors, isn't it annoying? Say that the security door is also warm.
A: There are two doors or two doors. In fact, there are two doors, and only the outer door is called a security door. In a renovation, the outside door is called a security door and the inside door is called a fire door. Because it is not a frame and two doors, the inside door is also called a security door.
39. Painters (Dulux and Nippon dealers) said that the primer should be brushed again, and the foreman who gave me the construction said that it was not necessary! Who am I listening to? I am in Zhengzhou!
A: The multifunctional paint requires a special primer, and ordinary paint does not. Depending on which paint you use, you generally do not need primers.
40. My house has hot water in the community. Please refer to the following questions:
1) I heard that it takes 5 minutes to turn on the faucet before it can go out of hot water. Is that really the case? If this is the case, I will simply use the water heater to seal the district's hot water. 2) I think the current hot water pipe is the same general metal pipe as the cold water pipe. Is there any problem?
A: 1. This is theoretically true. Because the original water pipe contains cooled water. 2. No problem.
60. I would like to ask: In the renovation, if I want to change the area of ​​the original room, can I pass through the Land Bureau? I have heard that under normal circumstances it is not allowed to change, but many decoration companies say that small houses can be converted into large rooms, and three rooms can be changed into four rooms. I wonder if they are not in compliance with relevant laws and regulations?
A: The Land and Resources Bureau only manages the building area. It is generally difficult to change the building area of ​​your house. It's just a big deal to increase the area of ​​the balcony. If you change the structure of the house, it can only be the structure of the plane layout. It cannot be the physical structure of the building. This is managed by the Construction Bureau. Please consult with your building management office.
61, I would like to ask: After polishing the wooden floor, how much is normal?
A: No specific measures have been taken. General grinding a total of three, it is also about 2-3mm wear it. The thickness of the wooden floor is 18mm.

For example, I do not pack door frames, do not include heating, do not hang ceilings, and do not use shelf corners and even kickboards. However, the floor cannot be unpaved. Always have to, how to do?
A: The problem is this: Formaldehyde is mainly found in splints. To minimize this effect, the main ones are:

A: Yes, but professional waterproof materials are used.
64. Hello, when you are doing cabinetry, your suggestion is to step up 10 cm above the floor. I would like to ask, can cabinets not be used as bases for kicks and sit directly on the podium? If the cabinets are purchased separately during the renovation, is the cabinet company responsible for installing the water intake and drainage system?
Another problem is: Now that the rooms are often closed, the air inside is not in circulation. How can we solve this problem? In the past, some renovations had opened a window on the door. I felt very old-fashioned.
Answer: 1) If you have a platform, you really can't kick it. However, you can also buy the plastic or stainless steel baseboard provided by the kitchen cabinet company, but it is not as durable as the platform. Kitchen cabinet companies generally do not provide drainage, but they are not absolute. You can consult them. Problems with the door leaf You can leave gaps or blinds under the door leaf. Of course, this will sacrifice sound insulation.
65. I would like to ask: The water in the toilet of my home has been displaced by about 70cm. Will the siphon type or direct flush type be used to make the water more open?
A: It does not seem to have much to do with siphon or flush. The main thing is how you shift.
66, old fire, hello!
My house has two bedrooms, the master bedroom wants to buy dark furniture (black walnut color, Shenzhen Dahao or Zhuhai Hengli brand, the style is relatively simple and elegant), the second bedroom let the decoration company to do the actual size, want to use teak wood surface . At the same time, all the doors, frames, sills, and skirtings also use teak, walls of white latex paint, ceilings with white. Want to ask a few questions:
1) According to this situation, what kind of materials and colors are selected for solid wood flooring? After reading the old fire post, the colors of the walls, floors, and furniture were well taught in order. Therefore, they wanted to select maple. However, the old fire also said that the material of maple wood is general and the color is light, which easily creates a top-heavy situation. Your experience, which materials and colors to choose the floor is good, the price of 150-250 can be? What is the effect of muskwood flooring? But do not like the golden colors.
2) Is teak placket suitable? From the master bedroom, black walnut furniture, teak placket doors, a certain color floor (would you recommend for me), OK? Or you can help me recommend what kind of surface, do not want to make the master bedroom looks too dark, but also think of the living room, bedroom all the same surface.
3) The white wall, white ceiling, do not want to ceiling, but also need to use dark shade?
4) Is it right? The bedroom and the living room should use the same type of solid wood flooring. Will someone use two different materials?
Thank you for the fire. I will wait for your answer.
Answer: 1) The floor is available with teak.
2) No problem.
3) Your plan has a darker color. It is a poorly-designed design. If you don't have a good balance, it will easily become a 60-year-old owner's home. If you are 60 years old, you're right.
4) It is best to use the same kind of floor. This problem of less convergence.
67, I intend to buy Haier 29-inch landing TV, so as to save the TV cabinet money. But how do you deal with the back wall? Can you get it with a simple bricklayer? The wall of my TV wall is connected to the restaurant on the left. I do not plan to cut off. The wall of the dining room is to be divided into two sets of cabinets. The right side of the TV wall is the entrance of the living room (the entrance is behind the entrance). I do not plan to make a door nor need to be cut off.
A: Then don't do a video wall, because the cost of TV back wall is much more than that of TV cabinet.
68, to ask you a question, I want to shop ceramic wear-resistant floor tiles, the use of dry shop method, shop floor tiles need to be flooded? How to dip?
Answer: The polished tiles and waved tiles do not need to be soaked, and ordinary ceramic tiles need to be soaked.
69. It was a solid wood floor for a while, and a solid wood floor for a while. The former said that the latter had a poor foot feeling. The latter said that the former is easy to deform and it is difficult to maintain. What I want is to have both a sense of foot and environmental protection. Grandmaster.
Answer: Solid wood flooring is natural, there is no backwardness.
I personally prefer solid wood flooring. However, it is recognized that solid wood flooring does not have the properties of solid wood flooring.
However, when it comes to the deformation of solid wood flooring, I think it is purely a technical problem, not a product quality issue.
70, old fire: Hello! My new house developer has installed PVC water pipes. I want to replace them with copper pipes. I wonder if it is necessary.
A: Are you sure you are a pvc pipe? I guess what you said should be a compound aluminum tube? Generally can not be replaced. However, if the use of harsh conditions, such as for hot water pipes, then consider replacing copper water pipes. Because of thermal expansion and contraction, it may cause the separation of water in the inner and outer layers of the composite aluminum tube.
However, if it is really just a PVC pipe, it must be replaced.
81. There is a wall between my restaurant and the kitchen. What should I pay attention to if I remove it for use as an open kitchen? I would like to draw Fang Zheng’s hall out of the dining room and paving the floor tiles, so what mix of kitchen tiles and restaurant floor tiles will be more harmonious and brighter? I make food is oily. Will it be contaminated in the living room? Thank you!
A: You have to cook the oil you want to use the open kitchen design, which is contrary to the design of the first principle: the first function, the second form. It is inevitable that this will cause pollution in other similar areas.
Remember, the above principle is a heaven-sent by designers all over the world.
82. The sound of the toilet plumbing of my toilet PVC is extremely loud. Every room is heard. How can we deal with noise?
A: Wrap up the tube. (You can use bricks or plywood, asbestos in the middle. Do not forget to use a plywood waterproof moisture treatment) (This article by the dragon reply)

84. Can anyone tell me what kind of interior decoration software is best to use now? The little girl here thanks!
A: The construction drawing uses autocad and the rendering is 3dmax. Process pictures using photoshop. These three major items belong to the standard equipment of the indoor industry.
After the above three software skills, you can play the enemy. Other software can learn after learning the above.
85, 1) If the hot-water pipe is made of aluminum-plastic pipe, I heard that after a period of time due to heat expansion and shrinkage, it will cause gap leakage at the interface. How can this be solved?
2) Ask the old fire to lay a layer of asphalt directly after leveling on the ground, and then spread the laminate flooring on the asphalt. Will the asphalt be flat? Will it be a bit soft? If I fear that asphalt will taste, can I put a layer of moisture-proof plastic film on the asphalt? However, I was worried that after 7 or 8 years, the film would dissolve or become sticky with the asphalt. This question has been asked before, but it's not very specific, the details are still not clear, plus I'm so stupid, so I'm sorry to trouble you again. Thank you! !
3) Once someone downstairs asked if I could paint the asphalt again, I would also like to know if that DX helped answer it.
A: 1) Hot water pipes suggest that you use copper pipes.
2) What kind of composite wood flooring do you mean? If it is a laminate flooring, you can use a moisture-proof membrane instead of asphalt.
3) Bitumen above the need to re-apply hot brush can paint latex paint.
86. A few days ago TV did not remember to use these days to remember where to buy. Thank you.
A: There are many kinds of wireless switches: radio, voice-activated, infrared...you know exactly which one, and it's not difficult to buy it. You can consult the lamps.
87, I seem to hear that there are gold xx dual-mouth floor from wax-free glue, do not have frame keel, this matter?
A: The design of the dual gear outlets certainly helps strengthen the firmness of the wooden flooring, but I have reservations about whether or not I am strong enough to use the backboard. In theory, most floors are free of wax and glue, and they don't know why they regard this universal thing as a feature.
88,1) What should be paid attention to when choosing shower room?
2) Which of the electricity and gas water heaters are worth buying?
3) Does the copper pipe need to be coated? A: 1) Pay attention to the material. Some surface-painted substrates may be poor materials such as stainless iron.
2) It is recommended to use gas (natural gas) because it is safer than electricity.
3) The copper pipe can not be plasticized.
89, What kind of brand does the sanitary ware cost-effective have? Is it necessarily imported? What is good in domestic brands?
A: To distinguish between different types. The toilet is best imported, otherwise you will be dizzy with the domestic poor quality flushing equipment.
Other sanitary wares, domestic or imported, are technically insignificant, mainly design/textured
90. Now that the house is ready to be renovated, there are several problems:
1) How to effectively prevent ants? The ants here are not the ants that eat wood, but the brown ants that are common on the ground and under the trees. Last year my parents' house was renovated. The ants often appear in kitchens and restaurants.
2) When paving a wood floor, when does the ground brush better (relative to the overall renovation project)? Is it time to lay the floor before Mason? Does asphalt need to dry out? How long does it take to dry? Does the asphalt surface need to be kept clean?
3) Is artificial stone easily scratched? Leave a scratch? Is it waterproof? Is it easy to seep for a long time? (compared with natural)
4) How do the partitions between the rooms make a good sound? The woodworking master said that there is no need to build a wall, what kind of board can be used, and space is saved. The mason said that it must build walls. The above questions are bothered by the fire or the masters.
A: 1. Go to the market to find a name called "XX chalk", I also forgot the specific name. The appearance is the same as our ordinary chalk, but it contains medicinal powder and it is used to draw a few lines on the path the ant passes. If there are several places, then there are several lines on the road where the ants of different nests pass.
Then you can ignore it. In a few days, this nest of ants will be completely extinct.
2. The timing of asphalt is before it is laid on the floor. Generally, it takes about 3 days to dry. Keep the original ground clean before brushing. After brushing, it is best to be clean. In fact, it is not technically harmful.
3. Both artificial stone and natural stone are less likely to seep, but natural stone has pores on the surface that can seep through the oil and make it look more oily. Of course, artificial stones are easy to scratch, but imports are easy to recover with sandpaper, and domestically produced artificial stones are not very good.
4. The effect of the red brick partition is certainly best, but now it is forbidden to use red bricks if you are high level. The woodworker should say light steel keel gypsum board. This board is also OK, but it must be filled with sound-absorbing cotton. Both occupy almost the same space.
91. Nowadays, there are many collective purchasing activities on the Internet. Can you join us?
A: Online collective procurement only emerged in 2002. The early launch was one of the decoration forums I managed, but I did not agree with this approach. On the one hand is the difference in shopping. On the other hand, the sponsor's motivation is not clear. And the price of collective procurement may not be very high. In the course of the operation, there have also been many unpleasant things. Even after the participation in the collective procurement, he is dissatisfied with the price and causes distrust to the sponsor. Of course, it does not rule out the existence of a trade-off problem. Therefore, this issue is hard to be quasi-problematic. I think it is a personal issue and one should think twice before proceeding.
92. Will the raw materials be used to seal the gas pipes?
A: In the south, we usually use raw material belts. In Beijing, I saw that the workers authorized by the Pipeline Gas Company used a tape.
93. The decoration of my home was shortly afterwards. A heavy rain fell some time ago and termites flocked. How do we do pest control?
A: This question says that complexity is complicated and that it is simple. The pest control is mainly concentrated in several ways:
1) Spray pest control water as much as possible during the renovation or afterwards. 2) Pure wood furniture purchased must be protected against pests. 3) In the spring and summer, when opening windows, it is best to have mosquito nets.
2) The problem of pest control is now mainly concentrated in the potion sector. Some companies use fake potions or reduced-dose potions to kill insects, and this problem is generally difficult for users to check. Therefore, I suggest to find the local epidemic prevention station prevention center or the trustworthy community management office.
94. My family wants to install a home theater. The decoration stage is now in the process of preparing the wall and the installation of the floor. I heard that there are active speakers and passive speakers. I really do not understand how these technologies should be handled. And you heroes shot help A: The speaker with its own power amplifier belongs to the active speaker, its own speaker without power amplifier is a passive speaker, we generally use passive speakers, the computer is powered speakers. The audio cable should be laid before the floor is laid. The method is the same as that of the wire. You need to add the pipe, but do not run the pipe parallel to the wire.
95. The house is three bedrooms. When the developers handed over the floor, two network cable ports were left in the living room and the master bedroom. There are two problems:
First: The two mouths are said to be at the same time taking the network cable and the telephone line. So how do I separate the network cable from the phone line?
Second: The other two rooms also want to go online. How to take over? Is it from these two mouths? So how do you connect? Connect each color line together? Still want to come in from the outside?
A: The blue line is the telephone line, and the yellow and green line is the network line. For other rooms to access the Internet, you need to install hub and cable extensions.
96. Everyone, Master! Hello everyone! What is the difference between the construction process of the younger brother who sincerely consults tatami and the solid wood floor? What are the special requirements for the plates used? Please enlighten me, thank you very much. Thank you. Answer: The real tatami is purchased from Japan. . Of course, I think what you said is not the kind of tatami, but a platform. The method is very simple, using wood or 15 PCT boards made into a shelf, and then a layer of 15 centimeters above the heart. The material above is up to you, but you cannot use materials that require cement, such as ceramic tiles.
97, paint primer curing agent can be added? Main agent: Curing agent: Thinner indicated 2:1:2 Is it reasonable for workers to add only a small amount of curing agent? Thank you very much.
A: Curing agents and thinners should generally be used in accordance with the instructions for use. They may change slightly with seasons. Different brands, types of paint, the required proportion is different. If the proportion is too much, it will affect the paint finish.
Answer: After the curing agent is added, the general paint should be stirred and set aside for a certain period of time. However, if it is left for a long time, it is prone to problems. Curing agents and diluents should generally be used in accordance with the instructions for use, and may change slightly with seasons.
