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. Higher pressure rates can be used to remove stains that may take time to be washed away on normal pressure ratting.
300 psi is the perfect rating that most cleaning contractors use hence they advise others to also use the same ratings as them. It is surprising to see most cleaning contractors using such low pressure rates even on tough stains that may seem difficult for you to clean.
The flow rate is the one that determines the time to consume while cleaning, hence the one who is cleaning should set the best pressure rate for the water. The contaminants on the pavement are also determined by the rate of water pressure how they will be quickly or easily washed away.
For those who do cleaning, they are advised by cleaning contractors to use a power machine that has a volume of 6 gpm or one that has a lesser volume of 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.
If you want to increase your cleaning speed then you should not use the standard nozzles but instead increase the nozzles of your rotary then you will have a positive results. 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. 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. For people who are using the power washer for the first time, the hot water power machine may not be the best type for them since it is expensive to buy it, it is heavy while using it and may seem hard to use for them.
The cold water power machine uses less aped in cleaning when compared to hot water power machine. It also reduces labor cost since you don’t have to spend much time cleaning.
