Wall ground base treatment problem collection
In the minds of many consumers, wall and floor decoration is the work of painting, wallpapering, tiling and flooring. However, in addition to the above-mentioned several items, there are also a lot of items on the quotations of home-improvement companies, such as wall leveling, yin and yang angle finding, and equality on the ground. So many people think that these may be the legendary “increasing items.†In fact, many wall and floor treatment projects are necessary. In this issue, we will make a special arrangement on the typical problems of wall and ground floor treatment. , let you spend money to understand. 1, only the walls of the old house need shovel shovel wall it This depends on the condition of the grass-roots level of the wall. It is not only the walls of old houses that need to be shoveled. For the new house, it is necessary to check whether the original wall surface is scratched by water-resistant putty. If not, the putty strength of the putty will be insufficient. At this time, it is necessary to scrape off the putty and re-scrape; while the old house needs to check whether the original wall surface is a sand wall because The wall of sand-gray wall is poor in paste ability, and the strength of water-proof putty is large. If the putty is scraped on it, the sand-gray wall must be removed to the original wall surface (red brick wall) and then the grassroots layer is processed. In addition, check whether the original wall surface is water-resistant putty, you can touch the first hand, non-water-resistant putty feel rough, rowing, and then water directly to the wall, if you use a knife or fingernails you can scrape putty, this It means that it is not water-resistant putty and it needs to be scraped out and redone. 2, door leveling processing In the new house, the doorway left by the developer was supported by the template of timber expenditure. When the template was removed, the cement mortar would fall. After the natural fall back, the cement mortar would be used to level the place. At present, about 50% of the door openings require searching. Whether or not you need to find a party is mainly whether the lengths of the two diagonal lines of the door opening are the same. 3, all the ground should be leveling it No matter whether the new house or the old house, there may be architectural errors on the wall. If the error is too large, it will affect the smoothness and appearance of the wall, especially when placing furniture such as wardrobes. If the previous measurement of the wall surface error exceeds 1cm, it is impossible to repair it with a putty, and there is a shadow in the backlight. At this time, it is recommended to level the wall. 4. Is it a concept that walls and walls and floor tiles are empty? If the wall base, putty and wall have been detached, a hollow sound will be heard with a pencil and a mallet, but if it does not fall, it indicates that there is an empty drum on the wall and it needs to be reprocessed. Empty walls are not allowed on the wall. The same method can also be used to check if tiles have empty drums, and the emptying rate of floor tiles and wall tiles cannot exceed 2%. Otherwise, it will have to be re-paved. This 2% emptying rate does not mean that two blocks of 100 bricks are empty, but refers to dividing the bricks into 100 copies, of which no more than 2 empty drums can be used. 5, old house repainting, can you directly refresh the paint on the original wall? The old house is repainted, and it is generally not recommended to refresh the paint directly without a base treatment. Interior wall brush latex paint is not waterproof, and the new paint contains water, if you directly brush, may cause some wall paint off, and the new and old paint formulations, containing materials are different, the two paints may be in direct contact Produce a chemical reaction. The old wall will usually produce cracks. If it is repaired with a construction bandage, it will be followed by scraping and sanding to cover the bandage. In addition, after several years of use, the primer will fail and need to be re-brushed. 6. What is the role of patches and stickers? What's the difference Cracks on walls, corners, light walls (differing in the degree of subsidence of main and light walls, light walls consist of multiple pieces, easy to crack), joints between lightweight walls and load-bearing walls, construction holes, etc. Where it is easy to crack, it is recommended to add strength and crack resistance by sticking the building bandage and attaching it to the fabric. Adhesive bandages are usually free, and kraft paper is not necessary for large areas. This cost can be saved. If it is a light sticker and putty, the wall color of the sticker part will be extremely heavy, so it is necessary to reapply the kraft paper. If the wall cracking degree is general, you can use grid cloth, if you need a large area of ​​the patch, it is recommended to use good cloth, because of its large cloth density, strong tensile strength, cracks are difficult to reveal. If the non-woven fabric is painted directly, it will appear ripples, and the cost is higher. This method is generally used for tooling, and the wall surface needs to be used for corrugation modeling. 7. Can you brush the finish directly after scraping it? Putty usually need to scrape 2-3 times. When scraping putty the first time, the putty may vary in thickness, flatness can not meet the requirements, in normal weather, need to scrape the first time putty after two days, until the putty is dry (drying time is long, you can avoid the wall The surface is damp and the paint is blistering. Then scrape it again the second time. After scraping putty, sandpaper will be used to flatten the putty flats, leaving trowels and seals, which need to be polished with sandpaper. This will also serve to clean the dust on the walls. After grinding, the primer is brushed again to function as an anti-mildew, anti-alkali, moisture-resistant, and increase the ability to connect, and the top coat is painted on the second day of the primer. The topcoat also needs to be brushed twice, while the dark paint is best brushed three times, because the first time the topcoat may appear uneven. 8, what is the yin and yang angle straight look The inside corner refers to the recessed corner, such as the angle between the top surface and the surrounding walls; the outside corner refers to the protruding corner, such as the angle between the window opening and the wall. The yin and yang angle is squarely beautiful. If the yin and yang angle errors are too large, it may cause problems such as cabinets and other furniture not being put in. If the measurement results show that the yin and yang angle error exceeds 0.6 mm, it is recommended that the yin and yang angle be straightened. 9, why the kitchen and bathroom before the wall tile to pull hair processing it Plastering the walls prior to tiling can increase adhesion and reduce emptying. Because if the wall surface is smooth, the wall brick and the wall surface have poor adhesion, and the wall brick can easily fall off. The kitchen and bathroom are to be inspected against the original wall before the wall is tiled. If the wall is a smooth cement wall, it is recommended to pull the hair. If there is a layer of hair, but with a hammer, the pull-off will have to be dealt with again. If the error of the wall surface does not exceed 1.5 cm, the cement mortar must be mixed directly with the wall lining without adding water, so that the burrs do not break and are more flexible. 10. At present, there are several wall leveling methods According to the original situation of the wall, there are generally three ways to level: 1. The sand wall of the old house must be shoveled to the red brick wall. At this time, the error of the wall will be relatively large. If it exceeds 2.5 centimeters, it needs to be leveled with cement mortar. The price is between 24 yuan and 28 yuan. Yuanpingmi; 2. Wall base is better, and the wall error exceeds 1cm, need to use gypsum leveling, the price is 14 yuan to 18 yuan / square meter; 3. Putty itself has a leveling effect, but the level of the leveling is limited to less than 3mm. If you simply use a putty to level out more than 3mm, drumming and cracking will occur. The problem may appear within six months. Basic wall surface cracking special treatment according to different base After the completion of the hydropower reform, the foundation wall treatment will be carried out. First of all, we must put the yin and yang angles (the corner of the wall refers to the angle of the recessed corner, such as the angle between the top surface and the surrounding walls; the surface angle refers to the protruding corner, such as the angle between the window opening and the wall). Leveling, first wall solidification, and then began to crack cloth. The location of the patch is generally the non-bearing wall, the junction of the load-bearing wall and the non-bearing wall, and the opening position of the construction hole. The purpose is to prevent cracks. Especially in the surrounding area of ​​heating, many people do not have a patch when constructing, and sometimes the walls are cracked for half a year. Bearing wall: In the places where there are cracks, light walls are best to be patched. There are cracks in the stickers. If you paste kraft paper, the effect will be better. After the cloth is finished, it must be puttyed. Before painting the wall, it is necessary to scrape the putty. Usually it takes 1-3 times, during which the normal dry time is 1-2 days. However, when scraping putty on rainy days, use a dry cloth to wipe off the wall vapour to keep the wall dry as much as possible. At the same time, according to the actual conditions of the weather, the time for putty drying should be as long as possible, generally 2-3 days is appropriate. After the wall putty is smoothed and polished, a varnish or base film is applied to the wall, and then the paint can be applied. Special wall: Mainly based on different grass-roots level to do a good job of crack prevention, of course, can not ignore the harmony with the overall home environment. Wallpaper combined with paint: The combination of wallpaper and latex paint solves the problem of easy cracking at the corners and creates a certain impact on the space visually. It is necessary to brush the paint first, then press the wallpaper on it again, and pay attention to the professional construction team when it is not possible to stick the wallpaper, otherwise it is prone to flaws and impetuousness. Hollow wall with artificial panel finishes: Generally used in the entrance or in the large space that needs to be divided. If you want the wall to hang objects, you cannot use plasterboard as the substrate, but use artificial boards. Putty putter on the artificial board, but the putty is thin without the wall effect, the putty is thick and easy to peel off, so it should be just right in the base layer. It is best to fight crack bandage before scraping. Wall insulation paint construction: Because the heat-insulating wall is hollow, it is easy to crack, so before the brushing is done, first line a layer of kraft paper that can resist cracking. Do not apply too much glue to prevent cracking when doing the substrate, which is not good for the health of the body. Children's room high paint wall: In order to ensure the effect of high-gloss paint, it is possible to add less water to the paint, even without water, and use a special spray gun for direct spraying, which will achieve a high brightness. It is easy to leave traces when using a high-grade latex paint roller, which may cause uneven color. Therefore, the paint concentration must be ensured.
