After a long period of use, the paint on the wall will gradually turn yellow due to exposure to ultraviolet rays and pollutants in the air. This not only affects the aesthetics of the wall, but also gives people an unclean feeling. Therefore, measures should be taken in time to deal with yellowed wall paints to restore the finish of the wall.
1.Clean the wall: Start by cleaning the wall of dust and stains, which can be removed with a vacuum cleaner or a soft brush. If you have stubborn stains, you can use a professional cleaner, but be careful to choose a cleaning product that won't cause damage to the paint.
2.Bleaching the wall: If there are still yellow marks after cleaning, consider using bleach to treat it. Before handling, protective measures should be taken, such as wearing gloves and masks, to avoid contact with ** and respiratory tract. After diluting the bleach, dip a brush into an appropriate amount of bleach and evenly apply it to the yellowed wall. After treatment, wash thoroughly with clean water to prevent residues left behind by bleach from damaging the paint.
3.Repaint: If the above methods do not solve the yellowing problem, then the best option is to repaint the wall. Repainting not only solves the yellowing problem, but also brings a new color and finish to the wall. Cracks and dents in the wall should be treated before repainting, and they should be filled with a patch. Then select the appropriate wall paint and apply it according to the instructions for use.
4.Use paint additives: In the process of painting the wall, you can consider adding some anti-oxidation and anti-yellowing paint additives. These additives help to extend the life of wall coatings and reduce the occurrence of yellowing and fading. According to the wall area and the amount of paint required, add the appropriate amount according to the instructions.
5.Regular maintenance: In order to maintain the beauty of the wall and avoid yellowing again, the wall should be maintained regularly. Wash the walls regularly to remove dust and stains, which can be gently wiped with a soft, damp cloth. In addition, avoiding prolonged exposure to walls in direct sunlight and humid environments also helps to extend the life of the coating.
Summary: Yellowing of the wall paint includes cleaning the wall, bleaching the wall, repainting, using paint additives, and regular maintenance. Through these measures, the finish and aesthetics of the wall can be restored, so that the wall can be restored to a new look.
