High pressure water cleaning is a great way to get dirt, grime and peeling paint off your home’s exterior. Done incorrectly or with the wrong pressure washing equipment, it is also a good way of taking off stucco, siding and brickwork.
Understanding Pressure Washing Equipment…
Ultimate Washer outlines that there are four ingredients to pressure washing that affect the outcome of the process: 1) cleaning solution, 2) heat, 3) pressure and 4) water flow rate. Pressure washing equipment that accommodates the use of hot water makes it possible to go a bit easier on the chemicals. Playing around with all four variables is as much an art as it is a science.
Not surprisingly, professionals in the home cleaning industry frequently offer to add a high pressure washer service to other exterior jobs. When inexperienced, these professionals have the potential of causing a lot of damage to a home. Marler’s Pressure Washing likens this experience to being someone’s “guinea pig” who might be working with self-mixed chemicals that can do quite a number on painted stucco and siding.
In addition, inexperienced handlers of the pressure wand may attempt to wash the exterior siding from the bottom up, which can actually result in a collapse of the siding setup. Aiming for a window possibly breaks the glass or forces water into the home via small holes or deteriorated caulking.
High Pressure Washer Pros and Cons
There are various nozzle tips used in pressure washing. Seasoned professionals — and well stocked rental services — offer a number of them for use during the procedure. Newbies and bargain basement outfits may only provide one or two nozzles. When used correctly, a zero degree nozzle can make quick work of any stain. If used improperly, it will take off loose stucco.
Not all chemicals are created equal. Some high pressure water cleaning solutions are made specifically for use on wood; others are made for use on bricks. Mixing and matching leads to undesirable results; examples include sticky wood or still-dirty bricks. Changing the chemicals during the procedure can make a huge difference and actually get the entire structure clean.
There is no advantage to pressure washing if the home is surrounded by valuable landscaping. Flora does not take kindly to the high pressure water, cleaning solution and amount of time it takes to do the job correctly. For less valuable — and not quite as closely planted — shrubs and flowers, it is possible to protect them with tarps that keep the spray and chemicals off.
