Pressure Washing: A Guide
For pavement cleaners it is advisable that they should use a power machine that has a pressure rate of 400 psi or more and has a flow rate of 5 gallons and bellow every 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.
It is the idea of most pavement cleaning contractors to use 300 psi since they argue that for them this will be perfect for all cleaning. 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. The water flow rate has the role of determining how the contaminants that might be found on the floor can be removed either at a slower rate or quicker than expected and easily.
It is the advice from many cleaning contractors that when cleaning one should use a power washer with the volume of 6 or one with 5 gpm. Gravity helps in removing the contaminants on the pavement when one is doing some cleaning to a pavement that is vertical, hence there is no need of using water flow rates that are high.
increasing the nozzles on the rotary instead of using nozzles that are standard so as to increase your cleaning speed. The nozzles that are at their standard position tend to deviate the water at an angle that does not make the water to flow faster. Water is twisted in an un-deflected water jet creating a circular path that enables the water to leave the nozzles at a faster speed when you are using the rotary nozzles.
So as to improve your speed of cleaning on the larger areas, there are wheel mounted powerful washers that look like the lawn mower. This power machine has got its nozzles mounted on the spinning bars that are located on the area that is made of metal.
Power washers that use cold water for cleaning are cheaper when buying them. The hot water power washers tend to be more expensive than the cold water ones and much heavier and hard to use for someone who is not used to do cleaning with the help of a power washer.
With all these variations the machine is faster when doing your cleaning than the cold water power machine. It also reduces labor cost since you don’t have to spend much time cleaning.
