To Sandblast Glass, you have to carefully clean the glass to be sandblasted to make sure there is no dust or dirt on the surface. You need to use choice of etch-resistant material firmly to the glass surface. After that, secure the glass inside the blasting cabinet. If the project is large-scale, you must use a blasting cabinet that has adjustable stands and securing mechanisms to hold the glass firmly in place during the blasting process. Then, Put on your protective eye wear and dust mask or respirator.
You should load your sandblasting media into the media hopper portion of your sandblasting cabinet. Next, attach an air compressor to your sandblasting cabinet and turn it on. If you are working with a large sandblasting cabinet, you can place your hands in the attached glove compartments of the cabinet. You have to grasp the blasting hose and pen. In slow even spray strokes; you need to apply the blasting material to your glass.
You must work from the upper left corner and moving from side to side. Once you have completely sandblasted your glass piece, you should turn off your air compressor. You can insert a shop vac to suck up all blasting media and return it to the hopper. Once the dust is settled, you have to gently pull a small section of blast resist material away from the glass surface to gauge the depth of the sandblasting. If the blast is not deep enough, you need to replace the resist and repeat the sandblasting process until desired effect is achieved.
Then, Remove all resist. You must clean glass with a commercial glass cleaner and let it to air dry.
