How To Fix Paint Blocking - The Issues

The Issue

Paint Blocking

Paint blocking is a common problem among painters and builders. It occurs when fresh paint is painted over another area that has been freshly painted. When the paint of both pieces dry, they adhere together. If one piece is removed, the other paint either peels away or paint from one piece adheres to the other surface.

Typically, paint blocking occurs when two adjoining walls are painted different colors. Paint blocking can also occur when painted surfaces are exposed to areas that have a lot of moisture. The moisture is able to weaken the hardened paint and allow the paint from two surfaces to adhere to each other.

Low Moisture Areas

Latex Paints

For low-moisture areas or an area that is currently humid but won't contain a lot of moisture in a few days, then using latex paints is the better option.

Latex paints have better initial block resistance because they dry very fast. However, latex creates an emulsion with water which will cause paint blocking over long periods of exposure to water or moisture.

If you are painting in an area that is constantly humid and full of moisture, then alkyd paints are the best option.

For High Humidity Areas

Alkyd Paints

Alkyd paints are better for high-moisture areas. They have long-term block resistance because they are made with hydrophobic materials that resist water.

If you are unsure of the moisture level in your specific area, you can check your windows or glass surfaces for condensation. As the water vapor in the air comes into contact with cool glass, it condenses from a vapor to a liquid and forms water droplets on glass surfaces. If this test is unhelpful or unreliable, then you may have to purchase or borrow a hygrometer to measure the relative humidity in the air.

Once you have identified the humidity level in your area and have decided to use an alkyd paint, then you should allow sufficient time for the paint to dry. You may also want to use talcum powder to help alleviate sticking.
