Japan emery paper

Types of Japan emery paper

Japan emery paper has several types depending on the granulation, flexibility, and purpose. For example, there are general-purpose, water-resistant types, and those specifically made for detailing. They include the following:

• Flocking type emery paper

  The flocking type of Japan emery paper is a special abrasive sheet designed primarily for flocking finishing. Flocking is a surface treatment where tiny fibers are adhered to a substrate to create a textured, soft-touch surface. Flocking type emery paper is preferred because it is highly flexible and durable. It can conform to complex shapes and contours, making it suitable for applying flocked finishes on uneven surfaces or intricate objects.

• Water resistant Japan Emery paper

  This type of Japan emery paper is designed to be used with water or other wetting agents. It helps in minimizing the clogging of the abrasive particles. The distinguishing factor of this emery paper is that while other abrasive papers disintegrate or lose their cutting ability when wet, the Japan water-resistant emery paper utilizes silicon carbide grains. They are consequently very sharp and cut effectively even when wet. This characteristic also makes it useful for wet sanding, which helps achieve a finer surface finish and minimizes dust during sanding. It comes in various grit sizes, from coarse for material removal to fine for finishing surfaces.

• Flexible back emery papers

  These papers are distinguished by having a very flexible backing, which can easily conform to uneven surfaces and into finely detailed areas while still applying pressure to flat surfaces. The flexibility allows them to be used on different surfaces and still give a very smooth finish. It makes the Japan emery paper suitable even for intricate woodworking projects. The flexible back minimizes the risk of creating flat spots on raised surfaces.

• Single-sided flocking papers

  They have abrasive grains embedded on only one side of the backing material. Japan's single-sided flocking emery papers are typically used with flocking machines. They provide a uniform abrasive action on the designated side to prepare surfaces for flocking finishes. They are quite effective in surface treatment just before the application of the flocked material.

Commercial uses of Japan emery paper

How to choose Japan emery paper

To choose the right type of Japan emery paper, businesses should consider the following:

• Project requirements

  The kind of project influences the type of grit to use. Coarser grits should be used for initial sanding. Finer grits should be used for the finishing stage. If the project involves working with hardwoods or metals that require extremely smooth surfaces, start with emery paper of ultra-fine grit.

• Material type

  While Japan emery paper can suit many materials, each requires a different grit. Softer woods require finer grits to avoid excessive material removal and harming the wood surface. Hard materials such as metal need coarser grits for effective material removal but transition to finer grits as the project nears completion for a smooth, polished finish.

• Sanding method

  Hand sanding requires emery paper with large abrasive grains, as this allows greater control over the sanding process. Power sanders require emery paper with small grains, which is more aggressive toward material removal. Additionally, always efficiently stick the emery paper onto the sander to prevent it from moving or tearing.

• Finishing needs

  For a brushed finish on wood or metal, use different grits of Japan emery paper successively to achieve a uniform surface. For a polished finish, use ultra-fine grits that leave no scratches. Use them one after the other until the paper reaches the desired level of smoothness. It is also important to clean the surface as it is sanded. This ensures the final finish is free of debris.

• Natural lubricants

  Where possible, lubricants should be employed on the emery paper to improve the finishing. Because they are water-resistant, one of the advantages of Japan emery paper is that it can be used wet. Wetting the emery paper forms a lubricant that reduces friction, minimizes clogging, and enhances lifespan. The paper can also be used dry, especially within the ultra-fine grits. The emery paper has minute abrasive grains that do not jam easily, even without lubrication.
