Pressure washer sandblasting is a technique that uses a mix of abrasive media and high pressured water to wear down a surface. It is becoming popular to minimize the dust a user deals with while sandblasting, and this type of washer is part of that movement. The water prevents dust from forming, which makes the process safer for your lungs.

In pressure washer sandblasting, a probe draws the abrasive media into the power washer extension wand, where water will propel it toward the surface at high speeds. The combination of water and abrasive media blasts away paint, rust, dirt, and other surface coating on the surface you want cleaned or smoothed. Different media are used for pressure washer sandblasting and each one provides a distinctive finish on the surface being cleaned.

Before starting a job, you want to consider the equipment and materials needed. Professional equipment comes

in many different varieties, as does the abrasive media. The particular task at hand will determine the appropriate equipment and materials needed.

Round Media types include glass bead, ceramic, and metal shot. These media clean, smooth, brighten, and descale surfaces. When heated, parts can be cleaned of light oils while leaving a bright or matte cosmetic finish.

Angular Grit Media includes aluminum oxide, crushed glass, and steel grit. These slurries are used for tough and aggressive projects. Coarse slurry is useful in engine rebuilding, descaling, removing rust, and degreasing parts.

Fine Angular Aluminum Oxide slurry can really deep clean and get into the pores of surfaces. This slurry leaves an even, clean, and abraded finish. As a result, less resin is needed to fill the voids.

Plastic Angular Media slurry deflashes plastic parts, and is also used for paint stripping.

Pressure washer sandblasting is a messy process. As the media shoots out of the hose and against the surface, it bounces off the surface and then settles somewhere in your work space. Any delicate surfaces in the immediate area should be removed or placed under protective covering. At the end of the project, there will be plenty of area to clean.

Remember to never point the nozzle toward anyone. The nozzle should always point downward when in use and the media supply line should be above the water line so the water doesn’t enter the media supply. The media hose should always be dry with the media covered throughout the project to prevent any contact with water.

At the start of your sandblasting project, hold the wand several feet away from the surface. If you get too close the object can get damaged. As you gain experience, you’ll find the right distance to maintain as you watch the results.

Pressure water sandblasting takes practice to perform properly. Before you begin an important project, practice and improve upon your skills on a comparable surface that isn’t of value to you. Practicing on something that doesn’t hold much significance allows you to perfect your technique without ruining the surface of what you ultimately need to work on.
