    : when the decoration season, many lack of decoration knowledge owners are distressed: workers know more, do not listen to the command. But the whole letter workers, but also afraid of stealing work to reduce materials. This issue, we start from the wall problem, one by one analysis of the site spread of the saying, so that you decorate clearly.
    1, I found a decoration company to do waterproof, and then let the tile dealer paste the wall tiles. After staying for more than a month, found that the tile large area empty drum, some tiles appear misplaced, the phenomenon of collapse. After removing some of the tiles, it was found that the cement layer was separated from the waterproof layer, which was glued off by the cement. Renovation company said that this is waterproof layer of paint film was glued off, is the tile laying process is not correct. Tile sellers believe that this is waterproof coating there is a quality problem. What's the whole responsibility now?
    experts answer: 3 space network decoration company technical director Sun Peidu introduced, such disputes if you want to technically divide responsibility, you need to find a testing station can issue a test report to field testing. However, the cost of testing will be thousands of yuan, ordinary consumers will think that the burden is too heavy. At present, he suggested that, in the absence of testing, the parties could be invited to negotiate joint liability or to be held proportionately liable for the costs they had collected.
    special reminder that the two construction responsibilities are difficult to
    many consumers are now more willing to allocate part of the project to different contractors. For example, the above owners will be waterproof and tile paving separately, there is a more typical is the hydropower renovation project and the rest of the home improvement company and home improvement company, respectively, think that this saves money. In fact, the home installation project needs the continuous cooperation of various types of work, so that once the subcontract problems on both sides are prone to the phenomenon of ripping.
    To hydropower transformation as an example, if the owners are required to do hydropower alone, decoration company in order to clear the responsibility, first of all, will do a delay in the duration, hydropower completely do a good job before the decoration team absolutely do not enter, originally some can cross-do the work can not be carried out. At the same time, hydropower companies are also required to do strict construction protection. The water pipe requires cement mortar to seal the groove, the circuit should also be protected in place, otherwise it is still not possible to enter. Problems, water and electricity transformation company said is the decoration company broke down, home improvement company said is not done well, in order to pull clearly, the industry mainly consumes double the energy. In addition, generally to the project node, home improvement company construction team workers if found that the previous work problems, will be internal communication correction, in the construction quality of mutual supervision. But if you do water and electricity alone, we all "sweep the snow in front of the door", even if the site has quality inspectors, will not say more about the work of others. So something went wrong and it was difficult to correct. In summary, it is recommended that you consider the subcontracted works before you do so.
    2, my home is being renovated, workers said the wall does not need special treatment, directly brush the wall solid on the line. Does this make sense? What is the main role of wall solidification?
    : Engineering experts explain that if the original wall substrate is very flat without empty drums, cracking situation, this is feasible. On the other hand, there will be problems. Owners can shovel their own original wall paint with a knife, if it is easy to shovel off, or splash water soon after wetting the wall, it is best to eliminate all redo the wall.
    as far as wall fixation is about, it's actually an interface agent that strengthens the substrate and allows other substances to cover it. If the owner's wall cement mortar ratio is appropriate, or used to find flat gypsum quality also pass, each step is in accordance with the construction standards, in fact, there is no need to wall solid. And the poor quality of the wall solids used may also result in layering of the walls.
    3, my wall has a lot of slender cracks, the wall construction workers said to belong to the crack, do not need to repair, scrape all over the putty cover. Is there any risk of this?
    experts answer: Sun Peidu said, this mainly depends on the degree of cracks in the wall, if the cracks are more obvious, there are 10-20 cm long, then need to be dealt with. At present, the general use of hanging anti-cracking net and scraping putty process to repair. And he cautions that such cracks appear in walls or light walls with insulation panels, and if left unprocessed, they will certainly appear in the future. Fine lines on the load-bearing wall are usually covered with putty.
    In addition, there are some small cracks in the home wall paint need to be partially repaired, experts said, if the original wall is large area intact, some areas have small cracks first for local repair and treatment, polishing after the primer, and then directly brush two paint can be. If the original wall has been powdered, the performance of a large area of skin needs to be the original wall skin shoveled off, re-scraped putty, brush the primer and paint twice. In addition, some wall paint labels have the function of making up small cracks, experts remind that this function is only temporary, some small gaps will be filled, but a long time will appear.
    4, my foremen told me that I had to use primer, so that I could save a lot of paint, after the wall paint is not easy to fall off. Is that right, please?
    : In fact, the biggest function of primers is anti-alkali. As a result, experts say, if the walls don't scrape putty again, you won't have to use primers. But if you scrape the putty, it's best to paint it again. And the primer only brush thin layer, for saving paint, enhance adhesion has no obvious effect.
    5, now the workers are painting the wall, according to the wall paint barrels on the instructions, should be 30% of the water, but the workers do not agree, must be 50%. 'It's too thick to brush,' he said. 'There will be stripes on the wall after brushing, and it's too hard to paint.' I don't agree, the workers have said they want to stop work. Should I listen to him, please?
    : Sun Peidu explained that the wall paint should be in accordance with its instructions to water. General good quality paint, need to be into 25%-35% of the water for reconcilicing. A bucket of white 5-litre
    latex paint
    theoretically brush 40 square meters of wall. And for color latex paint, in order not to affect the color of too much water, the same 5 liters can be brushed 30-40 square meters of wall (after water, brush twice). Based on the above data owners can infer for themselves that if there is more paint left over the area, it is thin brush;
    workers asked for 50% of the water, because if the paint in accordance with the normal proportion of water will be relatively thick, so that the process of painting requirements are relatively high, brush is not good obvious can be seen. Once in accordance with the ratio of 50% to water, workers are better to operate, but the paint effect is not full, even good paint will not appear texture, poor texture.
    , experts warned of other situations. For example, some paint quality is relatively poor, itself is very thin, then the water should be reduced. There are also workers who will put too much water in the primer, which will wet the otherwise dry putty. Construction is best in accordance with the primer instructions plus 30% of the water, so that you can brush again, according to the ratio of 1 to 1 water, it is best to paint twice.
    6, my home in the wall construction, the workers only polished with coarse sandpaper once, I insist on sandpaper again, but the workers refused, saying that only once is enough. Is that all right?
    : This is a construction specification, the general basic process requires must be coarse sandpaper, fine sandpaper polishing twice. For advanced craftsmanship, three sandpapers are required. Sun Peidu introduced, if only with coarse sandpaper polishing, wall paint will feel not smooth enough, the appearance of hemp noodles. Moreover, there is a direct link between the number of grindings made by workers and the cost of construction. "Premium processes are more affordable." It is estimated that the cost of work paid by the owners is not high, and the workers deliberately steal and cut materials.
    addition, if the wall stains need local paint, Sun Pei are reminded, be sure to use fine sandpaper to polish the wall, increase the adhesion of the paint. And this kind of polishing is not "which dirty grinding which", but requires the wall to be polished into a certain width, length and shed height equivalent to the rule shape. "It's natural and beautiful, and if the color difference is obvious, it looks like a map."
