Cardiff Pressure Washing
These days many people own an electric pressure washer for use at home.
So is it worth getting a professional pressure washing company to clean your driveway, patios or house?
What’s the difference between a professional set up and a domestic set up?
Electric pressure washers are great for washing cars. But when it comes to pressure washing hard surfaces they are not fit for the job. Entry level electric pressure washers start at around 100bar of pressure. When it comes to power washing driveways and patios you need to be using 200 bar plus.
But the main problem with domestic pressure washers is the volume of water they can produce(lpm). For around £39.99 you can find a small Karcher pressure washer that produces 5 lpm (liters per minute) and 105 bar. A professional pressure washing company should be using pressure washers running at around 21 liters per minute.
Of course, there are larger pressure washers needed for other avenues of cleaning, such as concrete cutting where pressure up to 2500 bar is used!
So what does the bar rating of a pressure washer have to do with the volume of water it pumps out?
If a bird is flies into your house wall at 30 miles per hour it will hurt itself, but the wall will be unaffected.
However, if a passenger plane flies into your house at 30 miles per hour you’re going to have to find somewhere else to live!
So if you were to use a jet washer with a relatively high bar rating, but a low amount of volume(liters per minute) it will not have as much impact, and cleaning power, as a pressure washer with a higher volume(liters per minute).
What else can a professional jet washing company do that you can’t do with a small pressure washer?
Professional pressure washing companies should always have a range of tools to use depending on the job at hand. By using telescopic lances, various fan nozzles, turbo nozzles, flat surface cleaners, to mention a few, it means the surface that needs to be cleaned can be cleaned in the right way. This means the wall, driveway, etc, will be cleaned to the best possible standard, without damaging the surface. Using the wrong attachment can cause a lot of damage if not done so correctly.
But is pressure washing just about jet washing?
Having the right equipment is vital to a pro pressure washing company. But the knowledge of what chemical to use, how to use it safely and effectively and when to use it, separates a decent power washing company from truly professional jet washing company.
