1. Direct repainting If the wavy line on the wall is not obvious, repainting can be used for treatment. Before repainting, clean the wall, then polish the holes and dents on the wall and fill them with polished paper. Before repainting, please make sure that the wall is completely dry, otherwise there will be wavy lines after painting.
2. Use the wall leveling agent If the wave pattern on the wall is deep and still exists after repainting, you can choose to use the wall leveling agent. Leveling agent can fill the depressions and defects in the wall surface and flatten the surface. Pay attention to the quality of the mixture when using leveling agent, otherwise it may lead to unsmooth surface or cracks.
3. Strengthening the wall structure In some cases, the wavy lines on the wall are caused by the instability of the wall structure. In this case, the wall structure can be changed or strengthened. This method may need the help of some professional builders, but it can ensure a long-term solution to the problem of wall corrugation.
4. Replace the wall If the above methods can't solve the problem of wavy lines on the wall, the last choice is to replace the wall. This decision may cost some money, but it is a powerful solution for severely damaged walls. Replacing the wall can restore the smooth lines of the wall, and you can choose to change the color and decoration of the wall if you want.
In short, the wavy lines on the wall make the wall look ugly, but there are many ways to deal with it. Whether you choose to repaint, use leveling agent, strengthen the wall structure or replace the wall, you need to pay attention to the seriousness and feasibility of the problem. I hope everyone can find a suitable way to restore smooth and beautiful lines on the wall.
