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


Mold 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 mold, be sure to clean thoroughly, scrubbing the effected 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 from 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, cleaning the surface thoroughly and allowing the exterior to dry completely before adding a coat of primer and applying a new coat of paint.
