• Alligatoring – The formation of cracks on the surface of paint layers.

• Peeling – A very common paint problem caused either by moisture or poor adhesion. It is characterized by the paint peeling and separating from an earlier paint layer (intercoat peeling) or from the substrate leaving some paint behind. Sometimes portions of earlier paint layers are visible under the curling, peeling paint layer.

• Blistering and Bubbling – Blistering occurs when the upper layer of paint loses adhesion and separates from older layers. Typically, this happens after the paint has dried completely, and there are no good guidelines for determining if or when it will occur. The problem can crop up within a day, or not until a year later.

The most common cause of blistering is applying paint to a damp or wet surface. Allow the substrate to dry completely before priming and painting. If there is a continual moisture problem (in a leaky basement, for example), it must be corrected before painting.

It’s also important to let the paint dry before exposing it to wet conditions. The weather channel is your friend! Avoid painting within four hours of a rainstorm; high humidity often causes blisters (sometimes water-filled) to form. If the surface dries out quickly, sometimes these will disappear. If a bubble remains after the surface dries, however, you’ll need to scrape it off and repaint.

In other cases, blistering is caused by applying paint to a dirty or incompatibly finished surface. As he paint dries, it shrinks slightly, pulling up poorly adhered sections of old paint. It’s important to thoroughly clean walls (both interior and exterior) before painting. Never apply oil-based paint over a latex base. It is possible to use latex paint over oil based primers and paints. But it’s better to stick with one type of formula. If your siding has been treated with linseed oil in the past, prime and paint with oil-based products.

Bubbles form as the result of a chemical reaction. This problem is far more common when paint is applied to a hot surface. Essentially, the top layer of paint dries, forming a barrier that prevents the solvents from escaping easily. At the same time, the hot surface causes the solvents to vaporize. These expanding gases put enough pressure on the paint to force it away from the substrate, creating a bubble. This occurs early on, during the initial drying phase.

• Wrinkling - occurs under three conditions - applying a coat of paint when the outside temperature is too low, when paint is applied too heavily on a hot surface or in the hot sun, or when not enough time. Has been allowed for the undercoats to dry properly. In either condition, the only solution to the problem is to sand the wrinkled finish, re-prime the area, and repaint. Wrinkling can be avoided by brushing all coats out thoroughly and painting in temperatures above 55 degrees and below 90 degrees Fahrenheit


• Efflorescence - a paint defect that is identifiable by crusty white salt deposits that bubble through the paint film from a masonry structure. Salts in the brick of concrete become dissolved with water and then leach to the surface as the water evaporates.

• Chalking - The formation of chalk (fine, white powder) on the surface of a painted surface is primarily due to weathering, which can give the appearance of color fading. While some degree of chalking is normal and can be a desirable way for paint to wear, excessive paint film erosion may result in unsightly heavy calk. Excessive chalking is caused by the disintegration of the paint film during weathering. Some common causes of heavy chalking include application to an unsealed surface, overspreading the paint, or poor quality paint.
