You've got your sandblaster attachment set up on your pressure washer and your abrasive ready to go. Now what? To get good results, keep your wand slanted at a low angle to the surface that you'll be blasting. Test a small area of the surface to get a feel for the results you're looking to achieve. Once you're ready to cover the remaining area, move at a steady and quick pace until you find the appropriate speed that works. Keep your nozzle about 18"-24" away from the sandblast surface as an ideal distance.
