As a specialist in the field of lacquer finishing, I can provide you with a comprehensive answer regarding whether you need to sand lacquer and how to go about it properly.
Lacquer is a versatile and durable finish that can add a high-gloss sheen to various surfaces, such as wood, metal, or even plastic. It is known for its resistance to water, heat, and wear. However, achieving a professional and flawless finish requires careful consideration of the sanding process.
Do You Need to Sand Lacquer?
Yes, sanding is an essential step in the lacquer finishing process. Sanding lacquer serves several purposes:
1. Smoothing: It helps to remove any imperfections, such as brush strokes or bubbles, that may have formed during the application of the lacquer.
2. Preparation: Sanding prepares the surface for the next coat of lacquer, ensuring better adhesion and a smoother finish.
3. Polishing: It can help to achieve a smoother and more polished look before the final buffing process.
When to Sand Lacquer
The best time to sand lacquer is after the final coat has fully cured. Curing times can vary depending on the type of lacquer and environmental conditions, but it's generally recommended to wait at least 24 hours before sanding.
How to Sand Lacquer
1. Wet-Sanding: This is the preferred method for sanding lacquer. Wet-sanding uses fine-grit finishing papers (typically starting with 800-grit and moving up to 1500-grit or higher) and water to smooth the surface. The water helps to reduce friction and prevent the paper from clogging with lacquer dust.
2. Avoid Dry-Sanding: Dry-sanding lacquer is not recommended. As you mentioned, dry sanding can quickly ruin your fine finishing paper due to the lacquer dust. Moreover, it can lead to scratches and an uneven surface.
3. Removing Orange Peel Texture: One of the primary goals of wet-sanding is to remove the "orange peel" texture that can form on the surface of the lacquer. This texture resembles the skin of an orange and can be unsightly. Wet-sanding with fine-grit papers will help to achieve a flatter and smoother surface.
4. Buffing: After wet-sanding, the surface should be thoroughly cleaned and dried. The next step is to apply a buffing compound and use a buffing machine or pad to bring out the high-gloss shine. This process will also remove any remaining fine scratches left by the sanding process.
5. Protect Your Tools: It's important to keep your sanding tools clean and in good condition. Rinse your sanding papers frequently during wet-sanding to prevent clogging and maintain their effectiveness.
6. Safety Precautions: Always wear appropriate safety gear when sanding lacquer, including gloves, eye protection, and a dust mask to prevent inhalation of dust particles.
In conclusion, sanding is a crucial step in achieving a professional-quality lacquer finish. By following the proper techniques and taking the necessary precautions, you can ensure a smooth, polished, and durable surface that will stand the test of time.

Once the final lacquer coats have cured, most finishers begin wet-sanding with fine-grit finishing papers. You want to remove the "orange peel" texture before buffing (see picture). 2. If you dry sand, you ruin your fine finishing paper in 10 seconds.
