Top tips for sandblasting wood

  1. 1. Sandblasting is used on wood for resurfacing, smoothing, or shaping. It is also used to remove unwanted finishes, such as paint, shellac, or varnish. Wood surfaces should be clean and smooth before repurposing, and sandblasting is the quickest and most efficient way to achieve an ideal surface to work on.
  2. 2. When sandblasting wood, considerations include safety precautions, abrasive material used, and type of equipment used. The process takes practice and a steady hand with cautious movements to prevent damage. Following the appropriate steps will lead to a successful sandblasting experience.
  3. 3. Wear protective clothing that covers all bare skin for safety. This includes an abrasive blast hood and gloves. When sandblasting, work in a well-ventilated area. The ideal working location is outside.
  4. 4. Fill the pressure tank with a suitable media for wood. Appropriate sandblasting media include: Soda A softer medium Walnut shells or corn cob A more abrasive medium Pumice A very abrasive medium for wood
  5. 5. Make sure to use the right size ceramic nozzle. The type of media used drives the size of the nozzle. For example: If you're using soda, use a 3/32” nozzle. If you're using pumice, use a 1/8” nozzle.
  6. 6. Test your skill with the media of your choice on scrap wood first. Holding the gun approximately 8 inches from the wood surface, hold down the trigger. You’ll want to move the gun from side to side over the wood surface. Each pass should only slightly overlap an already blasted surface.
  7. 7. Reviewing the test piece, you’ll want to look for defects, such as an irregular surface or pits. Test another section if there are issues, but move the wand at a quicker pace. If this isn’t successful, use a more aggressive media and retest. If this doesn’t work either, you’ll want to increase the output pressure in small increments and continue testing.
  8. 8. Once the test is successful with the final media and pressure selected, begin working. Always continuously move the gun in a thoughtful pattern, never concentrating the media stream on one spot. Frequently gauge your progress, and if more surface material than you want is being removed, you’ll want to work faster. However, if you’re not seeing as much surface material being removed as you want, then you’ll want to slow down.
