Common Exterior Paint Problems Encountered by a Las Vegas Painter

Painting projects may seem easy to complete. Some people even prefer doing it on their own. However, it is not as easy as people think, and experts don’t encourage it. You need the right products and a qualified Las Vegas painter to handle the task.

This is a Henderson painter focused on bringing the best commercial and residential painting services. The company has witnessed many people engaging them for solutions on a failed painting project. They always provide the same solutions. Here are some of the painting problems and how you can avoid them.

Blistering Paints

These tiny bubbles form under the paint. They are commonly found in wood and edges.


• The bubbles occur when dew or high humidity forms under the paint after dries. If the paint is exposed to direct sunlight, it may dry quickly, forming blisters.
• It could be due to poor ventilation, and the moisture in the house escapes through the walls.

Remedy and Prevention

You can remove the blisters using a scraper before you move on to apply any paint. Scrape the area and wait for it to dry before applying high-quality latex paint away from direct sunlight. You can also conduct repairs in your home to facilitate proper ventilation on the walls, roof and bathrooms. Checking for loose seals around the windows and doors can also help.

Alligators and Checking

This is where the paint film cracks and turns to a reptile-like skin. Checking also occurs similar to alligators, whereby the cracks formed are deep and severe in some places.

Causes of Alligatoring

• This occurs when the last coat is applied on a wet surface after the first coat.
• Applying the second paint over a glossy surface or a hard enamel causes alligatoring.
• The fluctuation of temperatures may lead to cracks and loss of elasticity for the paint.

Causes of Checking

• When a painted material ages over time, it expands and forces the paint to move, hence, losing elasticity.
• The aging of wood could also cause several layers of oil-based paint to be formed, leading to checking.

Remedy and Prevention

• Remove the previous paint and rub the surface to clear any paint particles, let it dry and apply latex paint.
• Using high-quality paint prevents the problem from reoccurring.

Efflorescence and Its Causes

These are salt-like deposits that appear on a painted construction. Efflorescence is caused by a lack of proper preparation of bricks and concrete during construction before the paint was applied. If no adequate waterproofing was done on the basement walls, the water from the ground could penetrate easily, leading to efflorescence. Moisture coming from inside the home could also be another cause. When you paint the walls before the concrete and bricks dry up completely, efflorescence occurs.

How Can You Prevent and Solve Efflorescence?

• Apply waterproofing to the walls of the basement if it is where the moisture is penetrating through.
• Scrape the walls and clean the area with a cleaning solution and clean water, let the place dry, and prepare and paint with high-quality house paint.
• Repair any cracks between the mortars and bricks where moisture may pass through and clean the window joints and gutters with a caulk.

Sagging and Running

This is paint that appears to be drooping. The sagging is caused by applying too much paint simultaneously or during the mixture; the paint gets too thin. Also, a droopy appearance is inevitable when you don’t use a primer or apply paint on a dirty surface. The weather may also be too cold when the painting is done, making the paint thick.

How to Avoid Sagging

• A brush or roller helps to spread the sagging paint to other places when it is still wet. This prevents sagging after the paint is dried up.
• When painting, use two light coats instead of one thick coat to prevent sagging.
• If you notice sagging after the area is dry, scrape the area and apply light paint evenly on the affected surface.
• If the painted surface is glossy, scrape the area and apply a primer, then repaint.
• Avoid overloading the roller or brush and use proper painting techniques.


Chalking appears as powdery chalk that forms on the painted surface. In many cases, chalking seems normal, but it can be a disaster in arid places. Exposure to extreme weather on a painted surface leads to the breaking down of paint binders. Excessive chalking leads to staining of the surroundings and is familiar with light-colored paints of poor quality.

It is caused by house painters using cheap paint that has high pigment additives. When interior paint is used for exterior purposes and a permeable surface is not sealed before painting, chalky particles start falling. The paint may also be overly thinned during the mixture.

Prevention and Remedies

• Scrub the chalky surface with a high-quality cleaner and rinse with water.
• Once the prime surface is dry, use the right latex paint for the whole area.
• If the problem persists after using a high-quality cleaning solution, you may need to engage a professional Las Vegas painter.
• Buy high-quality paint from a reputable painting company in Las Vegas.


This problem is seen as brown or green speckles and feeds on the paint film since it is a type of fungus. It is caused by moisture and thrives in poorly ventilated and wet areas. Applying paint on a surface without primer gives space for mildew to grow. When a lower quality paint is used without the use of a mildewcide, then the fungus starts growing.

Prevention and Remedy

• Wear protective gear, such as gloves, scrape the surface using household bleach or a high-quality cleaning solution and give it about 15 minutes.
• Rinse the area with clean water and wash again with a detergent and clean water for rinsing.
• Leave the surface for some time to completely dry, and apply high-quality latex paint.

Rust and Staining Encountered by a Las Vegas Painter

This is identified as reddish-brown stains on the paint film that tends to turn black. It is caused by using the wrong nails to attach siding or steel nails coming into contact with air. Steel nails may also pop outside the painted surface. When there is excessive weather, the nail head coating tends to wear out, leading to rust.

Prevention and Repair

• Identify the damaged nails and replace them with galvanized nails.
• If the nails are irreplaceable, scrape the head and drill them on the surface.
• Use a primer that has stain blocking ability and sand the surface smooth
• Paint over the surface using good quality latex paint.


This is the most common problem that house painters in Las Vegas encounter during painting projects. Paint usually peels from a previous layer and the concrete underneath. It is usually caused by poor adhesion and moisture. Also, when low-quality paint is used, or an unqualified residential painter does the job, the results are peeling.

Remedy and Prevention

• Scrape the affected area and add primer to the area you scraped.
• Completely caulk and repaint after the area is ready.
• Ensure that you use quality paint.
• Find a commercial painter to handle the project if it is a commercial building.
