How To Use Sandpaper Correctly?

1. Choose sandpaper

For hard materials, such as metal parts, coarser grit sandpaper can quickly remove surface defects; for softer materials such as wood, or surfaces that require fine sanding, such as the paint on furniture, lower grit is more suitable.

2. Auxiliary tools

When using sandpaper, it's important to maintain steady pressure. Too much pressure will not only damage the sandpaper but also cause excessive wear on the surface. Too little pressure won't produce the desired sanding effect. Therefore, we can use some tools.

01 Use tools

Use the sanding tool to ensure that the sandpaper is applied evenly to avoid excessive pressure that may cause damage or excessive wear on the material surface.

02 Hand Control

Use both hands to control the direction of the sandpaper's movement, keep your hands steady, and maintain steady pressure on the surface of the product being sanded.

3. Preparation for polishing

Before use, be sure to clean the surface of the object to be sanded. Dust and impurities are like stumbling blocks and will affect the sanding effect. Simply rinsing with clean water or using detergent can create a good environment for the sandpaper to work.

4. Polishing techniques

To ensure uniform sanding, cut the sandpaper into appropriate sizes and apply it manually or on a sandpaper rack. During the sanding process, ensure full contact with the surface, leaving no gaps.

For example, when sanding a wall, begin with a rough sanding followed by a fine sanding to achieve a smooth, even surface. For mirror-polishing molds, polishing should be done step by step according to the grit level, ensuring each step is uniform and meticulous.
