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.
Most contractors advise other pavement cleaners to use a rate of 300 psi while cleaning since for them it is the best in their work of cleaning. 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.
Once the cleaner has established the adequate water pressure to use while cleaning, then the flow rate is the one that determines the cleaning speed. 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. Higher water flow rates are not recommended to use when one is cleaning surfaces that are vertical, since there is some presence of You can consider using gravity that assists to remove contaminants from the floor.
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. If you decide to use the rotary nozzles then be assured of having a faster cleaning since the water will be twisted in an un-deflected jet hence creating a circular path that makes the water to leave the nozzles faster.
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.
Power washers that use cold water for cleaning are cheaper when buying them. 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.
Despite these differences the hot water power washer cleans faster when compared to a cold water washer. Little time is consumed while cleaning thus making the hot water power machine to be cost effective.
