Exterior wall painting mistakes to avoid

Painting your exterior walls might seem like an easy task. However, it requires patience, attention to detail, and some experience. Most homeowners make the mistake of thinking that they can handle the job themselves, only to end up with unsatisfactory results. Here are some common mistakes you should avoid when painting your exterior walls.

Choosing the Wrong Paint

Choosing the wrong type of paint is a common mistake homeowners make. When it comes to painting your exterior walls, not all paints are created equal. You need to consider the climate, the type of surface you are painting, and the overall aesthetic of your home.

Oil-based paints are best suited for wood surfaces as they penetrate the wood better and provide a more durable finish. On the other hand, latex paints work well on concrete, stucco and brick surfaces, providing greater elasticity. Furthermore, the colour of the paint should complement the style of your home.

Failing to Prepare the Surface

Another common mistake that homeowners make is failing to prepare the surface properly. Before painting, you need to ensure that the surface is clean, dry and free of debris. This can be done by using a pressure Washer or a scrub brush. Once the surface is clean, you need to prime it, especially if it is a new surface.

Priming ensures that the paint will adhere properly and provides a smooth surface for the paint. Failure to prime can lead to chipping, peeling, and flaking of the paint.

Ignoring the Weather

Exterior painting requires the right conditions. The ideal weather conditions for painting are between 50-90°F with low humidity. Painting during extreme weather conditions can lead to cracking, bubbling and peeling of the paint.

It’s also important to avoid painting in direct sunlight, as this can cause the paint to dry too quickly, leading to unevenness and unsightly brush marks.

Rushing the Job

Rushing through the job can lead to costly mistakes such as missed spots, overuse of paint, and hairline cracks. It’s important to take your time and be patient when painting your exterior walls.

Not Using the Right Tools

Using the right tools is crucial for a successful exterior painting job. Avoid using low-quality paintbrushes or rollers, as they can leave streaks or marks on the surface.

Using a good quality paintbrush will ensure that you can paint in tight spaces, while a high-quality roller will prevent drips and smudges.
