Air gumming is a commonly used term that is used for a form of fine blasting. The term comes from the French aerogommeuse.
The term air gumming is often used in conjunction with wood stripping. Paint, varnish and wax layers are removed from wood without any damage.
In practice, air gumming is carried out with very fine abrasives such as Garnet 200/350 mesh. Practice shows that when blasting granules are pressed through a thin nozzle, a more aggressive impact is created on the substrate. Air gums use a very low pressure in combination with a large nozzle. The jet grain then gets a different flow, which creates a “gumming” effect without impact. Below are some other tips that positively influence the result.
