Pressure Washing: A Guide
To clean your pavement effectively, then you should consider using a power washer that has a pressure rating of not less than 400 psi with a flow rate not exceeding 5 gallons each minute. It is good to wash away stains that may seem hard to remove or may end up consuming time when washing them, hence it is advisable that you increase your pressure rating to make your work simpler.
300 psi is the perfect rating that most cleaning contractors use hence they advise others to also use the same ratings as them. Majority of the cleaning contractors use this low rate even when washing the tough stains that may seem hard to remove and difficult for any other cleaner.
The main thing for the cleaner to do is establishing the best water pressure for them to use since the water flow rate determines the time you will consume cleaning. If the floor has some contaminants, then the water flow rate is the one to determine how one will easily clean them away quickly or slowly.
Many cleaning contractors advice cleaners to use a power washer that has a volume output of 6 or 5 gpm. When one is doing cleaning to surfaces that are vertical, then there is no need of using higher water flow rates since the gravity will help the contaminants to flow from the surface faster than expected.
You can increase your cleaning speed by increasing the nozzles of the rotary instead of using the standard nozzle. To create a fan pattern; the standard nozzles swerve the water at an angle which makes the water to slow down. Rotary nozzles twist an un-deflected water jet in a path that is circular so that when the water will be leaving the nozzle at a greater speed.
There are washers that have been manufactured similar to lawn mower with a wheel mounted shapes enabling cleaners to do cleaning on larger areas and at a quicker speed. This power machine has got its nozzles mounted on the spinning bars that are located on the area that is made of metal.
The price of power washers that uses cold water for cleaning is less in amount. Introducing the use of hot water use power machine may not be appropriate for people who are doing the cleaning with the power machine for the first time since it is expensive to buy, it is heavy and hard for them to use.
The cold water power machine uses less aped in cleaning when compared to hot water power machine. The hot water machine is cost-effective since one uses less time in cleaning.
