When medium-sized bubbles are found under the paint, these are called blisters. This is often found in trim or sidings made of wood. Sunlight sometimes causes the surface being painted to heat up. Vapor that rises becomes trapped during the painting process and results in these blisters. This is often the case when wood is being painted on because it absorbs moisture easily.

To solve this, the paint has to be scraped away. The wood or surface to be painted on should be allowed to dry so that no moisture remains. Painting is then done in non-direct sunlight, so choosing when to paint is important. The air should also be non-humid.


Fungus that feeds and grows on paint is called mildew. It can be seen as spots that are black, green, brown, or grey in color. They are found under eaves and soffits. These are areas that have lesser ventilation. There is also little or no direct sunlight, so growth of this fungus becomes possible. It may also be caused by not priming the wood prior to painting it.

The mildewed areas should be cleaned using trisodium sulphate solution. A bleach and water solution may also be used instead. The ration is three parts water to one part bleach. It is important to wear rubber gloves and proper eye protection when doing this. After removing the mildew, the solution should be left for 10 to 15 minutes. Rinse the area then wash again with a detergent solution.


When a powdery substance is found on the paint’s surface, this is called chalking. This normally occurs when paint is exposed to sunlight. If this occurs in the exterior of the house, the rain usually washes it away. Chalking may get out of hand at times. It then constitutes a problem if it affects the surrounding construction or people.

Excessive chalking is often caused by having too much thinner in the paint mix, using interior paint on the exterior, or not sealing porous surfaces before painting. Chalking can be removed easily, however, by power washing. Using the right paint and painting procedures is also important to prevent excessive chalking.
