Water blasting requires a powerful compressor, proper technique, and correct equipment setup. Regional water supplies should be considered, and bystanders should be cleared. Adjusting the pressure valve and nozzle is essential. Drought conditions may require alternative blasting mediums. Safety is crucial.
The best tips for water blasting are choosing a powerful compressor, proper blasting technique, and setting up the equipment correctly. Regional water supplies should also be considered; areas experiencing drought conditions may require a different blasting technique, such as using silica sand. Additionally, all surrounding bystanders should be cleared of the area to avoid accidental injury.
Water blasting requires a powerful compressor to force the water droplets out quickly enough to loosen paint or other surface coating. Accordingly, the consumer must check the specifications of the air compressor; the owner’s manual should list the maximum pressure the supercharger outputs and its application for each pressure level. Both electric and gas powered air compressors can be used for outdoor sandblasting.
Proper technique is imperative to remove paint and other substances when water blasting. The sandblaster should not be aimed directly at an area for a long time; rather, it should be moved from side to side in a steady motion. It is often good practice to choose a test area on the surface that is on the perimeter so that the pressure from the blaster can be tested for the correct resistance. Once the desired pressure has been achieved to achieve the required results, the user must then initiate a sweeping action to cover the remaining surface area.
Every water blasting process requires a good adjustment of the machine parts. The pressure valve must be set during the test area procedure; however, the blaster’s water nozzle should also be adjusted. A fan shaped water outlet will not produce the blasting power needed to treat the surface. Water blasting requires a narrow stream of liquid to have any effect on the finish. Slowly adjusting the nozzle will ensure a strong flow without damaging surfaces.
It may not be possible to use water for sandblasting if an area suffers from drought. Blasting requires many gallons of water to move through the system; this water is typically discharged into municipal sewer lines as waste. Before choosing a water blasting procedure, consider the water situation in your area. You may need to use an alternative blasting medium, such as sand or glass beads, to achieve the desired look. Safety should be the most important consideration when wet blasting and both people and animals should be kept away from the surrounding area as the force of the stream can easily injure someone.
