The Most Common Exterior Paint Problems

There are a variety of exterior paint problems that you can run into, and at Home Painters Toronto, we’ve probably seen them all. Luckily, most of these exterior paint problems are completely fixable. Whether it’s a case of wear and tear. Or the paint not being properly applied or maintained. There are a lot of problems that can wreak havoc on your home’s exterior. Here are the top 3 problems you could face when it comes to painting your exterior. And how to identify, avoid, and fix them.

Top 3 Exterior Paint Problems and Solutions

1. Mildew and Mold

Mould or mildew is a fungus that appears as dark green, brown, grey, or black spots on the surface of the paint. This phenomenon often occurs in shaded, poorly ventilated, or damp areas.

If your house’s exterior has mildew or mould, be sure to clean it thoroughly. Scrub the affected areas with proper cleaners before applying a fresh coat of paint.

Painting over mildew may be tempting, but it will only make the problem worse. Using a primer and high-quality paint can help protect your home’s exterior from this common problem.

2. Blistering

Blistering or bubbling looks just like its namesake: like bubbles or blisters that form underneath the surface of the paint. This is one of the waterborne paint problems that can be caused by moisture penetrating the paint. Even though the water evaporates, the paint film will stretch and stay blistered. This can also be due to temperature changes, painting when it is too warm. To fix this common exterior paint problem, scrape away the blistering paint. Sand the surface, prime, and paint. If the cause is improper house ventilation, be sure to fix the problem so that your house’s exterior paint job doesn’t end up blistering again.

3. Chalking

This will look like a fine powder, or chalk-like substance, on the surface of your paint, and is actually the deterioration of the paint resin. It usually comes from age or using low-quality paint, and is common in places with dry and arid weather conditions. Be sure to remove any paint chalk, clean the surface thoroughly and allow the exterior to dry completely before adding a coat of primer and applying a new coat of paint.

What are the Factors Responsible for the Deterioration of Paint?

While the most common cause of paint deterioration is age, there are other factors that can contribute to it. These include:

  • The type of paint used. There are different types of paints for different purposes. If you have used a low-quality paint product on your home’s exterior, for example, this could be a contributing factor to its deterioration over time.
  • How well it was applied. This can also prevent or slow down the deterioration process because an uneven coating will not last as long as one that is applied properly and evenly.
  • How well it was maintained. If you do not maintain your home’s exterior, including its paint job, then the deterioration process will be more rapid than if you did.
  • The environment in which it is used. Exposure to heat, cold, moisture, and sunlight can all contribute to the deterioration of paints.

TIP: The biggest mistake that people make when painting their home’s exterior is simply painting over old exterior paint. This can cause more damage than good because the new paint will not adhere properly to a surface that has accumulated years’ worth of dirt and grime.

It is always best to scrape off any loose paint and start fresh with a clean surface. This will ensure that your new paint job lasts as long as possible. It’s also a good idea to add a waterproof sealant when painting your home’s exterior, especially if it is located in an area prone to rain or high winds.
