Pressure washing your siding can be an excellent way to make it seem like it is brand new rather than being something that you have owned for several years by this point. However, sometimes this process can result in outcomes that are downright unexpected, such as the siding turning chalky once you are done with the job you had been focusing on. At the end of the day, this chalkiness is a very unfavorable thing to witness in your siding because of the fact that it can detract from its quality and reduce its life expectancy by a rather large extent.
Hence, you need to get to the bottom of why pressure washing Dickinson made your siding chalky to begin with. Suffice it to say that it is not the pressure washing itself that is causing this. Rather, it is the clean nature of the post pressure wash siding that reveals that chalky texture underneath. You see, when vinyl is exposed to oxygen, it can turn chalky because of natural chemical reactions that start to occur. This means that you need to seal it again after washing it, since this can help it to settle once again thereby giving it the appropriate level of hardness without making it overly brittle.
Another thing that can make your siding a bit soft and crumbly is the dirt that it had on it. If you left the dirt on the siding for a long time, it will break the structure of the material down which is what gives you the chalky feel that you so despise. Being proactive about cleaning it can keep this textural shift at bay in lots of ways.
