Article Body
If you are serious about cleaning the surfaces of your house, you can select any one between pressure washing and water blasting techniques. But to pick one, you need to clarify what surfaces you are planning to clean, where will you be cleaning and how long will you take to clean them?
Mentioned below are the key differences between pressure washing and water blasting that will help you answer the above questions with ease and will also help you make the correct choice between the two, based upon your requirement.

Pressure Washing
Pressure washing typically comprises of a pump, usually driven by a gas or electric motor. It comprises of a series of wands, hoses and various nozzles that are used to transfer the pressure boosted water.
The water spray nozzles are generally supplied with varying degrees of the fan patterns. The narrower the fan, the higher would be the water pressure. It consists of a jet nozzle, which is a straight stream and in fact it is the highest pressure stream that your unit will be capable of delivering.
In order to clean out the regular surfaces, make use of the broader fan nozzles. These nozzles are utilized to simply amplify the existing water line pressure to the point where the force of the blast is sufficient to displace the dirt. The type of nozzle you select and the power of your washer are used to determine the exact distance you should hold your wand and nozzle from the surface to be cleaned in order to have an aggressive and powerful spray.

Water Blasting
When you want some serious surface treatment via high pressure, it is here that water blasting comes in. The technique of water blasting involves the removal of a thin layer of a material along with the dirt. You can achieve outstanding results by selecting a suitable nozzle and rightly directing the altitude of the water fan towards a selected spot. But in case you fail to adhere to the correct technique, then you would have to face certain unwanted results.
Water blasting requires you to precisely follow the technique in order to avoid the undesirable results. If you dwell for too long into a single place, then there are chances that you’ll need to replace the divots. Plus, you also need to make sure that the broad face of the fan is always kept perpendicular to the direction of the surface being cleaned. Maintain a constant distance from the surface while maintaining a uniform motion moving from left to right and taper the starts and stops of the spray as it comes in contact with the surface.

You need to concentrate a lot on the technique because if you start or stop over the surface or hold the wand at the wrong angle, you can face unwanted and unsightly scars on your surface. Therefore you should always prefer hiring water blasting professional in Auckland, who’ll make the process much simpler for you.

As both the methods of pressure cleaning and water blasting require special attention and correct technique therefore you can hire professional. Many service providers involved with residential painting in Auckland offer such services, make sure to contact experts only.
