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.
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.
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.
Fill the pressure tank with a suitable media for wood.
Appropriate sandblasting media include:
or corn cob
A more abrasive
A very abrasive
medium for wood
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.
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.
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.
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.

Sandblasting quickly and efficiently resurfaces
wood. Working outside is ideal and protective
clothing should always be worn for safety.
Finding the right abrasive media, pressure, and
speed with which to move the wand will result
in a smooth wood surface.
