Nowadays, exterior paint is a lot stronger in the face of extreme elements than it was in the past; your paint job may last for a decade before it needs to be updated. But that doesn’t mean that you won’t ever face problems. Over time, exterior paint can begin to deteriorate, causing chalking, peeling, blistering, and more. Use the guide below to learn more about some of the most common exterior paint issues and what you can do to repair them.
As the name implies, chalking is when a chalky powder appears on a painted surface. A small amount of chalking is normal; it’s how paint cleans itself after it’s exposed to excessive rain or sun. However, if you notice a lot of chalking, it could indicate that your paint is beginning to break down. Chalking occurs more frequently with light-colored flat paints and low-quality oil paints.
When chalking appears, the only remedy is hiring a home painting service in Gilbert to repaint your home. Before painting your home, the chalking must first be removed. The painters will power wash your home and let it dry completely. Then, they will repaint your home using a high-quality latex paint.
One of the most common exterior paint problems is peeling. This can be caused by either poor adhesion or an excess of moisture. If bad adhesion is to blame, the new coat of paint separates from an earlier coat. You may notice a layer of paint left behind underneath the peeling layer. If the peeling is caused by moisture, you’ll see large sections peel off to reveal the wood underneath. Peeling spots are usually located around gutters, windows, and doors.
If the peeling was caused by moisture, the first step in fixing i t is mitigating the effects of the water. Start by ensuring the gutters are working properly to direct water away from your home. Additionally, you should install exhaust fans, vents, and dehumidifiers to help remove some of the excess moisture. Then you can begin to tackle the paint. Scrape off the old, peeling paint and sand down the areas. Remove any damaged caulk and replace it. Then, spot prime the affected areas and repaint them with a high-quality acrylic latex paint.
Blistering most often affects wood trim and siding. Small- or medium-sized bubbles, known as blisters, can appear underneath the paint. This can happen for a number of reasons. The color may have been applied when the wood surface was still wet, trapping moisture underneath the paint. Blistering also can occur when rain or humidity penetrates a dried layer of latex paint.
To remedy this common issue, you’ll first need to scrape away the blistered paint. Then, sand it down to the bare wood beneath. Allow the surface to dry completely before you prime and paint the spots. Be sure to use a top-quality latex paint. Additionally, you should avoid doing the work in direct sunlight or humid conditions. Otherwise, you will experience the same problem with blistering again.
