What is the process of wet and dry sanding techniques?

Wet and dry sanding techniques are two common methods of surface finishing, especially used in the DIY sector.

The wet sanding technique uses water or special water-soluble coolants to cool and lubricate the surface being worked on during the sanding process. The advantage is that the water dissipates the heat generated and prevents the abrasive from burning out or damaging the surface. In addition, the dust created by sanding is bound by the water.

• In wet sanding, the workpiece is moistened with water or another suitable coolant.
• The abrasive unit (sandpaper, stone, etc.) is also moistened.
• With a steady, sweeping motion, the abrasive is moved over the surface of the workpiece.

Dry sanding, on the other hand, uses no liquids. It is particularly helpful when the use of water or coolants is not practical or desired.

• In dry sanding, the abrasive is pressed dry against the workpiece.
• The abrasive is moved over the workpiece with pressure and often in circular motions.
• After dry sanding, it is important to remove the resulting dust to achieve a clean finish.
