Pressure cleaning or pressure washing is basically used to clean surfaces and materials. Concrete is one such surface that is perennially exposed to debris and several kinds of stains. Using a pressure washer on concrete is ideal especially when stains are tough and challenging. Although making use of a power washer can simplify most of your domestic cleaning chores, it is imperative that the user is well equipped with the knowledge of usage and possible harm it is likely to cause when mishandled. Also, there are several techniques that you can employ to make cleaning effective and hassle free.
This article deals with certain tips you can follow while pressure cleaning so that you can get rid of any kind of stains with relative ease.
(1) Preparation of the surface before using a pressure washer on the affected area is the first and foremost step in a typical cleaning operation. This is to primarily make your job easier and also to ensure safety. You need to remove any obstacles that are lying on the area meant for cleaning. Make sure to wet vegetation that is in close proximity and also cover for protection against damage. Cover all exposed electrical outlets and wires and finally remove all loose debris or objects. Such specific and miniscule aspects may miss your mind but are significant so as to ensure efficiency of operations and safety of person and property.
(2) Nozzle distances matter a lot when it comes to effective cleaning. When you need to clean concrete surfaces, you may have to make use of a 40" spray pattern. The nozzle distance varies according to the cleaning power of your power washer. When your equipment runs lower than 2000 psi, you should keep your nozzle distance at least a foot or even closer to the surface. For those models that run between 2000 psi and 3000 psi, about one or two feet is optimal. For more powerful models that run above 3000 psi, at least two feet distance should be maintained.
(3) When you are cleaning a large flat concrete area, moving the equipment wand all over the entire area is extremely time consuming. You may consider using a flat wheel mounted pressure washer. These models are easy to use, inexpensive and save time enormously. These work ideal for tennis courts, warehouses, parking lots and similar large stretches of area.
(4) Cleaning higher surfaces, on the contrary, demands meticulous attention especially when you get on to a ladder or a scaffold platform. Safety is of paramount importance. If you are using a power washer for the first time or are inexperienced, you may not be aware of the pressure the equipment is likely to exert on you when you use the gun. Gather complete information before use.
(5) Detergents or cleaners are an absolute necessity if you intend to do a neat cleaning job. However, the choice of product is completely dependent upon the kind of stain.
There are many tips you can follow for effective pressure cleaning operations. Knowledge of usage and safety precautions are however, mandatory.
