Painting is a great way to improve the look of your home, but if the paint isn’t sticking to the walls, it can be a frustrating experience.
When pain doesn’t adhere to the surface, it can cause peeling and flaking, which looks bad and can also lead to expensive repairs.
Many people assume that the problem is with the paint itself, but there are several other factors that can contribute to the painting not sticking to the wall.
Here, we will go over some of the most common reasons for this problem;
1. Incorrect Surface Preparation
If the surface is not properly prepared before painting, the paint will not have a good foundation to adhere to and will eventually peel. It’s important to clean the surface of any dirt, grease, or other contaminants before painting.
If you’re painting over a glossy finish, sanding the surface to provide a good key for the paint is also necessary.
If you’re unsure of how to prepare the surface, consult a professional painter or contractor. They will be able to assess the situation and recommend the best course of action.
2. Poor Quality Paint
Another common reason for paint not sticking to the wall is using poor quality paint. If you’re using low-quality paint, it’s more likely to peel and flake off the surface.
It’s important to use high-quality paint that is designed for the specific type of surface you’re painting. For example, if you’re painting a bathroom, you should use a specifically designed paint for bathrooms.
These paints are usually mildew-resistant and can withstand high humidity levels. Many hardware stores will have employees who can help you choose the right type of paint for your project.
3. Incorrect Painting Technique
Even if you’re using high-quality paint, if you don’t apply it correctly, it will not adhere to the surface properly.
When painting, it’s important to use even strokes and avoid going over the same area multiple times. If you do need to go over an area multiple times, make sure to allow the first coat of paint to dry completely before adding another.
Also, be sure to use a primer before painting if the surface is porous or has never been painted before. Applying a primer will help the paint to better adhere to the surface.
4. Extreme Temperature and Humidity
Extreme temperature and humidity can also cause paint to peel. If it’s too hot or humid outside, it’s best to wait to paint. The ideal temperature for painting is between 50 and 90 degrees Fahrenheit.
If the humidity is too high, the paint will take longer to dry and could start to blister. If you do paint in high humidity, be sure to use fast-drying paint and keep the area well-ventilated.
Research done by the Department of Energy has shown that proper ventilation can reduce paint drying time by up to 50%.
5. Poor Quality Paintbrush
Another common cause of paint not sticking to the wall is using a poor-quality paintbrush. If the bristles are loose or falling out, they will not be able to properly apply the paint to the surface.
Also, if the brush is too stiff, it can leave streaks in the paint. It’s important to use a high-quality brush that is designed for the type of paint you’re using.
Many hardware stores will have employees who can help you choose the right brush for your project.
6. Improper Cleanup
If you don’t clean up your equipment properly after painting, it can cause the paint to not stick to the wall. Be sure to clean your brush thoroughly with soap and water after each use.
If you’re using a roller, be sure to remove any excess paint from the roller before storing it. Also, be sure to clean up any paint drips or spills immediately.
If the paint is allowed to dry, it will be more difficult to remove and could cause the paint to peel.
7. Not Letting the Paint Dry
One of the most common reasons for the paint to peel is not letting it dry completely before adding a second coat.
It’s important to follow the manufacturer’s instructions and allow the first coat of paint to dry completely before adding another.
If you’re painting in a high humidity environment, it’s especially important to be patient and let the paint dry completely between coats. This will help to prevent the paint from blistering or peeling.
There are several common reasons why paint may not be sticking to the wall especially if it’s plaster. Always consider the above factors before painting to ensure a successful project.
If you have any questions, be sure to consult with a professional painter or the staff at your local hardware store. They will be able to help you choose the right supplies and give you tips on how to achieve the best results.
