In general, when sanding wood or other soft materials, it is recommended to use light pressure as heavy pressure can result in uneven sanding and may produce unwanted scratches on the surface. On the other hand, if you are sanding a harder material, such as metal or concrete, you may need to apply more pressure and use coarser grit sandpaper to effectively remove material from the surface.
Additionally, you should let the sandpaper do the work rather than applying excessive pressure, which can cause the sandpaper to wear out more quickly and result in an uneven surface. Therefore, the answer to whether you should apply pressure when sanding depends on the type of material and sandpaper you are using, and it is important to exercises caution and use the correct technique to produce the best results.
How much pressure do you use when sanding?
Applying too much pressure while sanding can lead to damage to the material, creating uneven surfaces, or even causing accidents such as sandpaper slips.
In general, it’s recommended to use a moderate amount of pressure while sanding, enough to keep the sandpaper in contact with the material but not too much to cause scratches or dents on the surface. A good technique is to apply light and consistent pressure, moving with the grain of the material if possible, and checking the surface regularly to avoid over-sanding.
Another factor to consider is the type of sanding tool being used. Different power tools such as angle grinders, sanding machines or orbital sanders, may require different amounts of pressure to be applied. It’s important to check the manufacturer’s instructions and adjust the pressure accordingly.
The amount of pressure used while sanding depends on various factors such as the material, the sandpaper grit, and the sanding tool used. It’s crucial to use a moderate amount of pressure, checking the surface regularly to avoid any damage, and following the manufacturer’s instructions when using power tools.
What air pressure for sanding?
The ideal air pressure for sanding depends on several factors such as the type of sanding tool you are using, the size of the sanding disc, the type of sandpaper, and the material being sanded. Generally, sanding tools such as random orbital sanders or belt sanders require a higher air pressure of around 90 PSI (pounds per square inch) to function properly, while smaller sanding tools such as palm sanders or finishing sanders require lower pressure.
When sanding with an air-powered tool, it is important to use the correct air pressure as it can impact the quality of your work and even your safety. Using too much pressure can cause the sandpaper to wear out quickly and produce uneven results, while using too little pressure may cause the sanding tool to stall or stop working altogether.
In addition to the tool and sandpaper, the material being sanded also plays a role in determining the appropriate air pressure. Soft materials such as wood, plastic or aluminum require lower pressure to prevent damaging the surface, while harder materials such as metal may require higher pressure to effectively remove the material.
It is recommended to consult the user manual of your sanding tool for specific air pressure recommendations, and to always test a small area before proceeding with larger sanding jobs. By properly adjusting the air pressure, you can achieve a smooth, even finish without damaging the material being sanded or the sanding tool itself.

What happens to sand under high pressure?
When sand is subjected to high pressure, it undergoes changes in its physical properties that can significantly affect both its structure and behavior. The impact of high pressure on sand depends on factors such as the type of sand, the composition of the sand grains, and the level of pressure applied.
One of the most visible changes that occur when sand is subjected to high pressure is its compaction. When grains of sand are subjected to pressure, they become more tightly packed together to form a denser material. This effect is caused by the pressure forcing grains closer to one another, reducing the air spaces between them.
As sand grains become more tightly packed, their volume also decreases, and their overall strength increases.
Another effect of high pressure on sand is the formation of new mineral phases. Under high pressure, sand can undergo a process called phase transformation, where its mineral components rearrange and form new mineral phases. This can result in the formation of new minerals that exhibit different physical and chemical properties from the original sand, making it more resistant to erosion, and changing its porosity and permeability.
High-pressure conditions can also cause significant changes in the internal frictional strength of sand. The frictional strength of sand is essential for stability and supporting structures, and under high pressure, changes in the frictional strength of the sand can lead to instabilities in structures or underground formations, such as landslides and sinkholes.
Sand subjected to high pressure undergoes compaction, phase transformation, and changes in its internal frictional strength. These changes can have significant impacts on the properties and behavior of the sand, affecting its stability and suitability for various applications. Understanding the effects of high pressure on sand is essential for engineers and geologists to design safe and sustainable structures and for geologists to understand geological phenomena.
