Everything, every day, can be seen in the "wall surface". If the wall is not well done, it will not only affect the overall environment of the home, but also make the mood of the occupants very poor . So what is the interior wall renovation step ? How do you trim the wall step by step? The details are described below.
The first step of wall decoration: inspection and treatment of the current status of the wall
Case 1: Cement wall. This is a common situation when new homes are delivered. The cement wall that needs to be painted should be thoroughly checked for solidness and flatness. If the wall is not strong enough or there are large cracks and holes, it is recommended to complain to the developer or property and ask them to redo or repair it.
Case 2: White wall. Nowadays, many commercial houses are already white walls when they are working. It seems that the cleanliness may actually be more dangerous. First of all, you should check the degree of solidity of the current wall and see if the existing white material is water resistant. If it is not resistant to water or water, it should be removed from the long-term use. For short-term use, it can be retained, but it is best to do it again and then perform other steps. At the same time, it should be checked as a whole whether there is an empty drum on the wall surface. In the place where there is an empty drum, it must be shoveled off. Other inspection items are the same as in case 1.
Situation 3: The wall has been decorated. Wall surface has been decorated with wallpaper or latex paint, which is common in second-hand houses. In general, the original surface decoration should be cleaned up when performing this secondary decoration. If it is a wallpaper, you should first remove the wallpaper. If it is a latex paint, you should first polish the latex paint. After the surface decoration is removed, you can refer to Case 2 to determine whether to shovel the wall.
Step 4: Thick screed processing. Professional leveling repair mortar is required.
If it is a cement blank wall with good flatness and flat yin and yang angle, basically no need to use leveling repair mortar for large-area thickness leveling, you can directly use the functional leveling material ecological type putty, and the scraper can be used for fine leveling. . If it is uneven, the yin and yang angle is not straight or the wall of the shovel wall, it is necessary to use the leveling repair mortar to make the thickness leveling with the trowel, and the gypsum board ceiling needs to be leveled with the caulking plaster putty. It effectively avoids the problems of poor adhesion, cracking, hollowing and formaldehyde pollution caused by 801 glue + double fly powder + gypsum powder + talcum powder mixed putty base.
Step 5: Fine leveling. Water-resistant putty and functional ecological putty are required in wet areas.
After the thick leveling is finished, the functional ecological putty can be used for leveling with a scraper. It is necessary to pay attention to full uniform stirring, single batch scraping thickness and grinding timing, etc., to avoid quality problems caused by human factors. The flatness after fine leveling should be controlled to ±1 mm.
Step 6: Polish the putty.
After the water-resistant putty is stabilized and hardened (usually 5-7 days), it will become very solid, and it will be extremely difficult to polish it at this time. Therefore, it is very important to choose the timing of grinding. It is recommended that the general water-resistant putty should be sanded when it is semi-dry, that is, it is not deformed by light pressure, and there is no watermark on the side. It is polished with 360# sandpaper. Grinding can be done at night, with a light bulb of more than 200 watts close to the wall lighting (the light bulb needs to be leveled during the day), while polishing to check the level of flatness.
Step 7: Brush the primer or brush the base film.
If the decorative layer is brushed, polish the putty and clean the surface of the floating dust, then you can apply the alkali-resistant primer. The primer roller can be applied once, and it must be even. After it is dry (usually 2-4 hours), the next step of the roller coating can be carried out. If you choose to wallpaper, you need to brush a base film first.
Step 8: Brush the topcoat or wallpaper.
The wall paint is usually applied twice by roller, and each time should be separated by 2-4 hours or more (depending on the dry condition of the surface) until it is substantially dry. After the second coat is finished, it takes 1-2 days to completely dry out. Before the paint is completely dry, it should be waterproof, drought-proof, dust-proof, ventilated, and sun-proof to avoid problems with the paint film. If the wallpaper is applied and the base film is dry, it can be wallpapered.
Step 9: Acceptance.
The wall should be solid, flat, vertical yin and yang, no cracks, no holes, uniform color, full of paint film, wallpaper texture stitching, no trace, no bubbles, but also pay attention to check the protection of the finished product.
