Do you have to use it? "Wall fixing is actually a kind of interface agent, which plays a role of connecting the preceding and the following, consolidating the base and allowing other materials to cover it If there is some dusting on the interface to be processed, the back cover can be used But he said that if the owner's wall cement mortar ratio is appropriate, or the quality of gypsum used for leveling is also qualified, every step is in accordance with the construction standards, in fact, there is no need to fix the wall Nowadays, many people use the wall with color, but they think that the interface agent with color powder may affect the adhesion "It should be colorless and transparent." Industry insiders said that many home decoration companies use wall fixing with color to facilitate management, "for example, the interface agent is yellow, so that workers can be tested to see if the putty and wall paint are up to standard, which can cover the yellow color." It has also been pointed out that if the quality of the wall reinforcement itself is not up to standard, the interface is too smooth or the sundries at the base are not cleaned, it may also cause the situation of wall stratification Question 2: "the worker said that the original paint of my old wall doesn't need to be shoveled, and the paint can be refreshed by directly brushing the wall Is this feasible? "Experts said that if the original wall base is very flat without hollowing and cracking, it is completely possible to do so But if the substrate is not very good, there will be problems The owner can also shovel the original wall paint with a knife during construction If it's easy to shovel off or wet the wall quickly after splashing water, it's better to completely remove and redo the wall (DI Gu's question: "my home is an old house in the last century There is a problem of sanding on the ground The workers say that only one floor of Di Gu can solve the problem Is this the case? In addition, I saw a kind of ground ash handling agent called floor companion on the Internet, saying that as long as it is applied to the ground, it can completely solve the problem of sand, is this reliable? "The ground solid simply means a layer of sticky material, which can seal the dust on the ground Painting it can make the ground in the whole process of home decoration construction without dust, its main role is to make the whole construction environment cleaner, and has no impact on the specific construction quality of the ground Ground consolidation does not solve the problem of ground sanding "In the current newly-built housing, there is generally no ground sanding phenomenon In the old house, if the ground sand is not serious, in fact, the impact on the tiling and flooring is relatively small However, sand raising is particularly serious, which needs to be solved by a new cement mortar layer, and ground consolidation is not feasible " The floor companion mentioned by the owner has not been contacted by him at present, but it can be confirmed that this is a remedial measure for ground sanding "To cure the symptoms is not to cure the root cause." He introduced that the ground sanding is due to the insufficient cement ratio, which should be fundamentally solved, at least a new cement mortar layer should be made □ primer question: "many shopping guides have introduced that primer can save the top coat, make the top coat Fuller, and increase the adhesion Is primer required? "Primer is not required for all walls The most effective primer is alkali resistance If the walls in the home are not re puttied, the primer may not be applied But when the putty is newly applied, it's better to brush it once A lot of shopping guides introduce that primer can make the top coat fuller In fact, the primer is only applied with a thin layer, which has no effect on saving the top coat and fullness Now many workers will mix too much water in the primer when they are working, which may backfire "There is too much water in the primer, and the putty that was dry has been wet again." During the construction, it is better to add 30% water according to the primer instruction, so it can be brushed once If water is added according to the proportion of 1:1, it is better to brush twice If the workers add too much water to the primer, the function of the primer will be greatly reduced After the primer dries completely, mix the water according to the normal proportion to brush once again Home of coatings is specialized in coatings, diatom mud, paint coating, coating technology, fire retardant coating news and coating, diatom mud, paint coating, coating technology, fire retardant coating decoration knowledge and decoration renderings,
