Eight steps to teach you to paint the walls yourself

Preparation of materials for the steps of painting the walls yourself: cement mortar, interface agent, putty powder, wall paint, etc. First prepare the materials you need, and then according to the product description, according to the different proportions of the preparation. Tool preparation: The commonly used tools for wall painting include color separation paper, kraft paper, wall paiting rollers, brushes, putty knives, sandpaper, etc. Steps and methods of operation: 1. Basic treatment: Clean up the peeling and loose parts of the wall, and repair it with cement mortar. Where there are cracks, kraft paper tape and white latex are generally used to stick to the cracks. Generally, non-load-bearing walls such as light-weight walls and thermal insulation walls need to be pasted. Try to choose better wall cloth and white latex or grid cloth. The grid cloth will have a better anti-cracking effect. 2. The interface agent can be brushed. Enhance the adhesion to the base layer, avoid the hollowing and shelling of the plaster layer, thereby replacing the manual chiseling process, saving time and effort. When brushing the interface agent, it must be brushed evenly. 3. Wall leveling The uneven wall needs to be leveled, and the uneven wall should be leveled with plaster, so that the error of the wall does not exceed 3 mm. If the yin and yang angles are not straight, plaster plaster should be used, and a ruler should be used to make it straight. 4. Putty with higher particle fineness and harder texture is better, and the putty should be batched three times. The first pass is generally thicker because it involves levelling. The second and third passes are thinner, mainly for lightening, so that the wall looks smoother and flatter. After three batches, the thickness of the putty should not exceed 3mm, otherwise it will be easy to crack. 5. Polishing is a very critical step in the painter's steps. After polishing, the final paint effect can be good. Try to use finer sandpaper. If the sandpaper is too thick, it will leave deep marks. After polishing, be sure to clean the wall thoroughly to avoid too much dust and affect the adhesion of the paint. The unevenness is no more than 3 mm. 6. The primer must be evenly painted to ensure that every part of the wall is painted. If the wall has a large amount of paint, it is best to add a little more water to the primer to ensure that it can be used. Apply evenly. 7. After the putty is polished, there will be some blemishes. Under normal circumstances, it is difficult to see clearly. It will be obvious only after brushing the paint once. At this time, it is necessary to find repairs. Pay attention that you must polish it evenly, and then use a primer with a little more water to avoid color difference when you paint the top paint because of the difference in draft from other walls. 8. Do not add too much water to the top paint, which will affect it. The thickness, feel and hardness of the paint film. Try to choose better tools. When painting, pay attention to the corners of the walls, the indirect stubble part of each roll, and the direction of the paint collection. The surface paint is generally painted twice and the wall paint construction process has eight main steps, followed by basic treatment, brushing interface agent, wall leveling, scraping putty, sanding the wall, brushing the primer, repairing the wall, and brushing the surface. paint. Each step has its own operation method and construction requirements. When painting the wall, you need to do each step well in accordance with the specific requirements.
