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.
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. 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.
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. 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.
Wheel mounted power washers that resemble lawn mower have been made to make cleaning interesting for cleaners who do cleaning on larger areas. Nozzles have been made on the spinning bars that are found on the area that is metallic on this type of power machine.
The price of power washers that uses cold water for cleaning is less in amount. 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.
Despite these differences the hot water power washer cleans faster when compared to a cold water washer. The hot water machine is cost-effective since one uses less time in cleaning.
