Question: “Why are there marks on my bathroom walls that look like streaks or drips?”
Surfactant leaching is a common problem on bathroom walls, particularly in areas with high humidity, such as near showers and baths. Surfactants are chemicals that are often present in paint and can migrate to the surface of the paint film when exposed to moisture or humidity. When this happens, the surfactants can form a visible residue on the surface of the paint, which can make it look streaky or discolored.
Surfactant leaching can be caused by a number of factors, including the type of paint used, the application method, the climate, and the ventilation in the bathroom. To prevent surfactant leaching, it is important to choose a high-quality paint that is specifically designed for use in high-humidity environments. In addition, proper surface preparation and application techniques can help ensure that the paint adheres properly and is less likely to experience surfactant leaching.
If surfactant leaching does occur, it can usually be cleaned off with a mild detergent and warm water. However, if the problem persists, it may be necessary to repaint the affected area with a high-quality, moisture-resistant paint. It is also important to address any underlying humidity or ventilation issues in the bathroom to prevent surfactant leaching from reoccurring in the future.
