Pressure jet washing is done at pressures varying from 1200 psi to about 3000 psi. Ultra high jet pressures of up to 25,000 psi are also used for industrial applications. You really wouldn’t want to blast off the surface of the material. Pressure jet washing in London would tell you that one would only be interested in getting the dust, grime and dirt etc. removed away from the surface and not blasting away the surfaces. Materials like wood and aluminium are to be worked with lower pressure jetting water, close to about 1200-1300 psi. High pressures of say 3000 psi can actually cut holes through the woodwork. Older bricks and mortar were relatively softer and high-pressure water could very well chip off pieces of brick and mortar. Pressure jet washers are classified into 3 or 4 basic categories.
For residential purposes pressure jet washing is mostly used to clean driveways, pathways, and patios. Sometimes these are also used for exterior house cleaning on surfaces where the paint is not applied. Due to weather effects that is not unusual to find the exterior paint slightly chipped off on many concrete walls in houses. By blasting such surfaces with a water jet would tend to chip off more paint from the walls. Pressure jet applications are better suited externally for unpainted concrete, brickwork, flagstones, synthetic material wall coverings, and floor surfaces. Exterior pathways, driveways, and patios are very effectively cleaned with this method. Moss, weeds, grime, sandy grit, dirt, and residue are adequately removed. Some cleaning companies use brick cleaning devices that will route hot water downwards to a spinning water delivery device and will not damage the pavement, concrete or flagstone. With these machines, a vast water spray back is avoided and the cleaning is very potent. Pressure jet washing in London applications is used in industrial as well as commercial applications. When working with materials that tend to chemically react with liquids, eco-friendly water is one of the safest choices causing the least amounts of fumes and vapor to rise. Some typical commercial and industrial uses being
In choosing a professional water jet company, research on a number of companies should be done. Customer reviews should be carefully read before selecting a company, with the aim of finding a company that delivers a quality service at economical prices.
