Why Paint Cracks and Peels

Picture this: You suddenly find the paint job of your dream house suddenly cracking, peeling and falling off. It must be a nightmare to see your paint job in such a state. Luckily for you we have compiled some of the most common reasons of cracking and peeling of paint.

There are many reasons why paint will crack and peel but we will only write the most common explanations. Hopefully this will help you in identifying the cause for your cracking paint and in solving these problems.

Moisture
Moisture is a great enemy of paint. If you find your paint cracking and peeling, moisture may be seeping in from the outside damaging your interiors. Check to see if the cracking and peeling of paint on your walls is due to moisture. If the location of the cracking and peeling paint is at your ceilings, your roof might be leaking. Locate and fix the source of the leak before you apply a new coat of paint.

Sometimes, condensation may also cause paint to crack and peel. Some areas prone to condensation are the edges of metal casement windows. In order to solve this, you should install storm windows and apply caulking to the frame.

Unprepared Surface
Washing and cleaning the surface to be painted on is an important step in paint jobs. If a recently painted surface begins to crack and peel, an unprepared surface may be the reason. Before applying paint, ensure that the surface to be painted on is clean and free from moisture. Following this simple step may save you from frequent repainting and increase the life and durability of your paint jobs.

Brittle Coats
Paint naturally deteriorates over time. Painting on a surface multiple times may ultimately cause cracking and peeling. The older coats will have become brittle over time. This decreases the ability of the new coat to bond with the old coat. This might cause the outermost layer of paint to crack and peel off. To solve this predicament, the old layers of paint need to be removed before applying the new paint. The previous paint may be removed with the use of paint remover to the surface. Starting from the initial coat also gives new life to a surface and increasing the durability of the new paint.

Alligatoring
The development of numerous fine cracks along a painted surface is usually called “Alligatoring”. It is called alligatoring because in the most advanced cases the paint will look like the cracked skin of an alligator.

A paint job wherein paint is applied to a surface too quickly and not allowing it to dry and expand properly will most likely result in alligatoring. In order to remedy this problem, again, all the coats of paint should be removed using paint remover. Then the surface must be painted again. Make sure to leave adequate time in between application of coats to allow the paint to properly dry and expand.
