A Must-Read for Those Who Want to DIY Exterior Painting! What Are the Advantages and Disadvantages of Using Spray Cans for Painting?

Hello everyone!KakeruKoumuten Co., Ltd. is here!

Many people may be considering painting minor color fading or unevenness on their exterior walls with a spray can.

That said, “Is it really possible to paint exterior walls with a spray can?”

I believe many of you might have this question.

In this article, we will explain in detail whether it is possible to paint exterior walls using spray cans.

DIY exterior wall painting with spray cans is not impossible

To put it simply, DIY exterior wall painting using spray cans is not impossible.

By purchasing a spray can suitable for the exterior wall and applying it correctly, you can achieve a satisfactory finish.

However, while there are advantages to painting exterior walls with spray cans, there are also disadvantages and precautions that must be considered, so it is essential to have the correct knowledge before proceeding.

If you start without any knowledge, there is a high possibility that you will not achieve a satisfactory finish or make irreversible mistakes, so caution is necessary.

What are the benefits of painting exterior walls yourself with spray cans?

Next, let’s take a closer look at the benefits of painting exterior walls yourself using spray cans.

Cost savings

By painting exterior walls with spray cans, you can significantly reduce costs.

If you hire a contractor, various expenses such as paint costs and labor fees will arise, and it is not uncommon for the total to exceed 1 million yen.

However, by using spray cans, even including other tools necessary for exterior wall painting, it is highly likely that you can keep costs down to a few thousand or tens of thousands of yen.

Ability to paint only noticeable areas

Many people may want to paint only the areas of concern rather than the entire exterior wall.

By utilizing spray cans, it becomes possible to perform painting and repairs in limited areas, increasing the likelihood of resolving your concerns.

Additionally, if the area is limited, the working time will be significantly shorter, and the area that needs to be protected will also be smaller, making it possible for beginners to carry out the painting.

Simple Method

When you hire a contractor for exterior wall painting, skilled craftsmen use specialized equipment and tools to carry out the work carefully.

It is quite difficult for someone with no knowledge or experience to handle the equipment and tools used by craftsmen.

However, with spray cans, as long as you don’t make mistakes with the distance to the object or the color, anyone can use them, making it easy to carry out painting.

What are the disadvantages of doing exterior wall painting yourself with spray cans?

Next, let’s take a closer look at the disadvantages of doing exterior wall painting yourself with spray cans.

Since the disadvantages are more important than the advantages, if you are considering using spray cans for exterior wall painting, I recommend reading through to the end.

High likelihood of peeling

When painting exterior walls with spray cans, there is a high possibility that it will peel off quickly.

This is because when you hire a contractor, they often use paints that are less likely to peel, which increases costs but makes subsequent care easier.

However, commercially available spray cans, even if labeled “for exterior walls,” tend to peel more easily compared to the paints used by professionals.

For this reason, even if you use spray cans for exterior wall painting, there is a possibility that you will have to repaint soon, which can be inefficient.

High likelihood of color unevenness

While exterior wall painting may seem simple, it is quite challenging.

The most difficult part is avoiding color unevenness.

If someone with little knowledge or experience tries to paint by imitation, there is a possibility that it will turn out a different color from other areas, resulting in a very unsightly appearance.

Painting large areas is difficult

Spray cans are suitable for painting limited areas.

Therefore, if the diameter is a few dozen centimeters, it may be possible to repair it yourself.

However, for large area painting, using spray cans becomes quite inefficient, and there is a possibility of unevenness, leading to disappointment when seeing the finished exterior wall.

If the exterior wall becomes too unsightly, you may have to hire a contractor again, resulting in double the work.

Risk of injury

If you are painting within reach, it can be done relatively safely, but when it comes to painting high areas, the risk of injury increases significantly.

Typically, when performing exterior wall painting, scaffolding is first set up before painting the higher areas.

However, in many cases where exterior wall painting is done with spray cans, scaffolding may not be available, so ladders will likely be used for painting.

That said, for those who are not accustomed to working at heights, the risk of falling increases significantly.

Many people underestimate this kind of danger, but depending on the situation, it could lead to life-threatening accidents, so it is recommended that those who lack confidence do not push themselves.

Reasons to Strongly Recommend Hiring Professionals Instead of Using Spray Cans

It is not impossible to paint exterior walls with spray cans.

However, considering quality, safety, cost, and efficiency, it is better to hire a professional contractor than to do it yourself.

Now, let’s take a closer look at the reasons why hiring a contractor is advisable.

Painting Exterior Walls with Spray Cans is Not Practical

Painting exterior walls with spray cans is not very practical.

As mentioned earlier, it is not a problem if you are just doing minor repairs in a limited area, but attempting to paint a large area solely with spray cans is extremely inefficient.

Moreover, if you are doing the painting yourself, you will inevitably be working alone, which can lead to a significant amount of time being taken to complete the job.

By hiring a contractor, several craftsmen can work together, allowing for quicker and cleaner results.

Knowledgeable and Experienced Staff Will Handle the Job

If you hire a contractor that specializes in exterior wall painting, knowledgeable and experienced staff will come to assist you.

Exterior wall painting is a task that tests the skills of the craftsmen, so if you want a more beautiful finish, it is highly recommended to hire a contractor.

Your Burden Will Be Reduced

By hiring a contractor for exterior wall painting, you can significantly reduce your burden.

By having a pre-meeting with the contractor and conveying your preferences to some extent, the contractor will handle the work itself, so you won’t expend energy or risk injury.

While this will incur some costs,

・Finish Quality
・Risk of Injury
・Your Effort

Considering various factors, it can be said that it is better to hire a contractor even if it means paying for the service.

Summary

It is possible to perform exterior wall painting using a spray can.

However, if someone without knowledge and experience attempts to paint on their own, there may be color inconsistencies, or paint may end up on areas that should not be painted.

Additionally, the risk of injury increases, so considering these disadvantages and risks, it can be said that hiring a contractor is more efficient even if it incurs a cost.

Especially for those who want to achieve a beautiful paint job over a large area, I strongly recommend hiring an exterior wall painting contractor instead of doing it yourself.
