Many homeowners try to cut costs by conducting home improvement projects, such as painting exterior walls, on their own. However, some inexperienced homeowners may make some mistakes that will affect the quality of the work that they have just done. This article discusses some common exterior paint issues and explains what you can do to prevent those problems.

Temperature Blisters

Temperature blisters refer to the air-filled swellings on the surface of newly painted walls. Rapid temperature changes make air bubbles to form within the inner layers of the paint. However, that air cannot escape to the surface because the top layer of the paint has hardened due to the heat to which it has been exposed. Temperature blisters usually form when you paint your walls in the morning. The rising sun causes the temperature to rise rapidly until bubbles form in the paint. Affected areas have to be scraped and repainted.

You can prevent temperature blisters by painting the walls when the heat from the sun is waning, such as late in the afternoon. The low temperatures that follow will allow the paint to dry or set evenly without creating an opportunity for blisters to form.

Inter-Coat Peeling

Inter-coat peeling refers to the separation of one coat of paint from the one below it. For instance, the primer coat may separate from the top coat. Several factors can cause this problem. For example, taking too long to apply a top coat may cause it to peel from the primer. Additionally, painting products may peel from each other if they aren't compatible with one another. Improper surface preparation can also cause inter-coat peeling.

Prevent this problem by being meticulous about surface preparation by cleaning the walls thoroughly and fixing any defects. You should also buy painting products (primers and top coats) from the same source so that you avoid product incompatibility. Apply different paint layers at the recommended intervals.


Newly painted exterior walls may exhibit signs of staining. This usually happens because metals, such as nails, rusted due to moisture exposure. Staining can be prevented from affecting your newly applied paint by applying rust inhibitors on all nails before you paint the walls. You should also make sure that the walls are completely dry before you start painting.

Many more defects can mar the quality of the newly painted walls. Talk to a provider of exterior painting surfaces for tips on how to prevent your handiwork from succumbing to defects. Alternatively, hire experts to handle the painting job so that they use their experience to forestall all the problems that can make that exterior paint to fail prematurely.
