Aerogumming

Functions on the principles of sandblasting, with the following differences :

1. The nature of the abrasive is adapted to the substrate to be treated. Different types of abrasive will be used depending on whether wood, metal or stone, for example, is being treated.
2. The size of the abrasive (also called grain) must be adapted to the surface to be treated. On old wooden furniture, don't attack with 80 grit, as this will dig into the wood too much and disfigure the furniture.
3. The quantity of abrasive to be propelled is adjusted according to the thickness and hardness of the surface to be stripped or cleaned.
4. The air flow rate (pressure at which the abrasive is propelled) is adjusted according to the substrate. On an airbrush the pressure ranges from 0.5 to 8 bars.

All this with the sole aim of not damaging (denaturing) the treated substrate and satisfying the customer's expectations.
Furthermore, all the abrasives used, whether Garnet, walnut shell, Sodium bicarbonate, Calcium or glass granulate, are :

• NATURAL,
• ECOLOGICAL,
• HEALTH-FRIENDLY.

The right choice of abrasive is paramount to achieving the final treatment result desired by the customer.

Cryogenic cleaning

In the dry ice blasting technique, the solid abrasive used in Aerogommage is replaced by small pellets of " dry ice " also known as " dry ice ".

The principle remains the same in that dry ice (-79°) is propelled by compressed air onto the surface to be cleaned. Ice pressure and flow rate are adapted to the substrate, depending on its consistency, hardness, state of soiling or fragility.
Under the effect of compressed air, dry ice pellets (up to 3 mm in diameter) are accelerated to a speed of 150 m/s. At a temperature of -79°C, the pellets freeze impurities and crack on impact. Thanks to their high speed, dry ice pellets can then easily loosen dirt. This is a particularly effective method for removing virtually all impurities with the utmost respect for materials.
