Do You Know about Rough / Medium/ Fine Sanding?

Do you know the application you need to sand when you choose a coated abrasive product? It is critical to choose the proper grit/grit sequence if you know the sanding application, but also affects other factors, such as the different grits of sandpaper, backing and sanding method (machine or hand) and so on. Grit is sized by a gauge number, with lower numbers signifying larger, rougher grits. Next, we will tell you in detail sanding paper types, what is rough sanding applications, medium sanding applications and fine sanding applications.

Whats the Application of Rough Sanding

Rough sanding applications are those heavy stock removal, stripping down edges on furniture, deburring or removing rust from metal, etc., will generally require a more heavy-duty product with a more sturdy backing – such as cloth basing or a heavier weight paper. Film products also offer a durable backing option, but this will not be suitable if this process is happening in a belt sander. Rough sanding applications will typically require lower grits(80 or even lower), and more aggressive sanding action, such as in a belt sander.

Rough sanding is not recommended for fine details or for edges and corners that you want to keep sharp. Also, be very careful using this on veneer polywood since the thin face layers are easy to sand through.

Whats the Application of Medium Sanding

Medium sanding applications would include final shaping and removing of marks from previous sanding applications, as well as preparation for finish. Such as surfacing paint. These applications would typically range from about 80 grit sanding discs-150 grit. The most often-used gauge of grit is in the medium range. For most applications, it is hard to go wrong with sandpaper grits in this range. This grit is usually used for bare wood surfaces. For whatever type of projects you work on, it is always beneficial to have medium-grit sandpaper on hand.

Whats the Application of Fine Sanding

Fine sanding including applications such as sanding between coats of finish and polishing. Seldom used on the first run-through, unless the surface is already smooth to the touch, fine-grit sandpaper in this range is typically for second or third sanding. Bare wood that will be stained often should not be sanded with higher than 220-grit paper. This includes both wet and dry sanding applications. Generally, fine sanding is in high grit sandpaper like grits 180 and even higher. Both aluminum oxide and silicon carbide are used in finishing applications.

Grain options According to Application

  • As for thegrain options, choosing a product with Aluminium oxide sandpaper uses will be a nice option if sanding wood.
  • Though with raw wood, you might choose zirconia oxide sanding paper for woodfor milling applications.
  • For harder metal, choose zirconia oxidesandpaper for metal if you are removing burs or paint.
  • For stainless steel, zirconia or ceramic is the way to go.
  • Silicon carbide in coarser grits can be utilized for removing paint, burrs or rust, as well as in floor refinishing to remove the previous finish.

Conclusion

On many projects, we usually use different grits of sandpaper during work, like start with a coarse grit and then switch to a finer grit for a smooth finish. When you learn how to choose the right sandpaper, you will find that starting with various coarse-grained alumina papers for initial sanding, to fine-grained papers for fine sanding, a variety of works can be found in a very smooth surface is formed in your hands.
