Why is it important to clean your home before doing a residential house painting Wacol? Well, simply because if you paint your home right away, you may have to do it again the second time since the paint will not last a long time.
While your walls can live without you cleaning it, but this just means you have wasted money from buying the paint and all the effort may just be a waste because the result will not be as what you expect. By painting on a dirty surface, you will just shorten the lifespan of the paint which you may have to paint again if that happens. Consider how difficult and expensive exterior house painting, which is why you have to get it right the first time.
So how should you properly prepare the exterior walls? One simple way is to use a pressure washer. While you can still clean your house exterior by using a soap wash and wiping all areas by hand, but this will really take a lot of time. Just like when you go to a car wash and they use a pressure washer for your car, the same effect of removing dirt and grime will happen to your exterior walls and you do not have to wipe all corners with your hand. A pressure washer will just simply make your life easier and the process will be faster.
However, the use of a pressure washer can also cause problems if used incorrectly. You can damage the sidings and create cracks too if you are not careful. With that in mind, you can ask your painter if they also include power washing the exterior walls as they know the right pressure to use for exterior walls without damaging your property.
