Finally, use a pressure washer and strong solution to clean your exterior walls thoroughly. Remember, it is important that you do not rush into things because you need to ensure that the surface gets enough time to dry.
Before embarking on the painting job, select the best spray tip for the surface that you intend to spray paint. The size of the tip should not exceed your sprayer’s maximum capacity. In case you want to combine paint from multiple containers, mix it well in large, empty gallon-containers. This will enable you to maintain good color consistency, especially if there exists color differences between individuals paint cans.
Practice Using the Paint Sprayer
If you have no experience when it comes to spray painting exterior walls, it is important first to practice using the paint sprayer against a disposable surface such as a plank of wood. This will enable you to become familiar with the rate of the spray as well as familiarizing your self with how the trigger operates because it will help you to achieve optimum consistency and also save a bit of time with the paint sprayer. You can also practice spray painting on a flat surface that nobody can see, maybe a side of your house that nobody can see. Start by spraying the caves, undersides or overhangs. This will give you a good idea of how the rest of the spraying will occur.
The Spraying Process
The spray paint process goes initially in sections and do not move too far in one go. It is best to spray paint at a length of 12-inches from the surface. A tip extension can also be used to get to all the areas that are hard to reach.
Next, work on the outer edges and then move onto the inner corners. This will allow you to cover all surfaces accordingly. Once the heaves are already sprayed, work on the exterior walls, themselves. It is advisable to start at the top of the wall and move downward in smooth motions. Otherwise, if you start at the bottom, you will be obliged to move upwards using a ladder. This may result in a sloppy spray paint job
Then, spray paint with a steady stream by keeping the sprayer about 30cm away from the wall. Always keep the sprayer at a 90-degree angle from the wall. Take special care not to add any additional paint to the corners which the sprayer passes constantly.
Lastly, you need to finish the coat of paint at the bottom of the wall. The best way to do this is by keeping the paint sprayer several inches from the wall.
Things to Consider
While spray painting may only require a few basic rules, there are other factors that you need to take into account as well.
Never stop moving the gun whenever you pull the trigger while the paint is blasting out. The minute you stop spraying, a pile of glop will appear on your exterior walls and this will affect the coating by causing an uneven surface that will force you to start painting allover again.
For best results, you should use long, sweeping strokes with your arm regardless of the direction that you are painting.
Do not keep the spray paint on the surface as you switch directions. Otherwise, this will cause a buildup of paint.
Use enough paint because the number one cause of a poor paint job is the lack of paint.
While using a paintbrush or roller is much easier and more predictable than spray painting, it is always best to embrace new painting techniques that will make an impact on your results. There is a lot to learn about spray painting, but with the right technique, you can achieve professional results. That way you will save a lot of money because you won’t have to call an expert to do the painting job.
Take all the right precautions because it is easy to spread paint to unwanted surfaces if you are not careful enough. The steps mentioned above will ensure that you master the art of spray painting exterior walls. After use, remember to clean it accordingly because proper maintenance is a crucial factor if you want the sprayer to last.
