How to Sand Wood Like a Pro: Know the Different Ways
For DIY enthusiasts, sanding is necessary when it comes to deal with wood. Pretty much every DIYers know how to sand, but most of them don’t know how to do the task more efficiently.
It's even more critical for the beginners as well. The beginners might have seen the way wood is sand, but they lack practical knowledge regarding the matter.
This article will guide you to sand wood properly, and let you know pretty much everything you should know about sanding wood.
Ways of Sanding Wood
I’ll show you how to sand wood in different methods. But, first, let’s get familiar with the types of sanding. There are primarily two ways to sand wood:
Sanding by Hand
This provides the most control over the wood surface. By manual sanding, you can sand corners and recesses that are difficult for a sanding machine to reach.
Even if you use a sanding machine to sand a piece of wood, still you will need to sand by your hand for best results on areas that the machine cannot reach.

To get an even smoother surface, you can use a sanding block. It allows you to apply more pressure on the wood and doesn't let the sandpaper slip or bunch.
Besides, using a rubber or foam profile sander makes it easier to achieve a sharp and professional look on the surface.
If you must sand through curves and form around the edge, use your hands instead of sanding block to make a satisfying arc shape on the wood.
Sanding by Power Tools
Using power tools is the most comfortable option. It saves a lot of time and effort. However, there are various types of sanding tools available in the market. Orbit sander and palm sander are one of the most popular ones among them.

A sanding tool sands the wood quickly and makes the wood evenly smooth. One of the issues that you might come across is the sawdust that is produced while sanding. However, you can avoid facing it if you connect a shop vac to the sanding tool.
Now, let's get introduced with different types of sanding tools so that you can figure out which one is more appropriate for your DIY project.
Orbital Sander
This sanding machine is the most widely used one. You will find an orbital sander in every woodshop. One of the significant benefits of using this sander is that it can eliminate scratch marks that are created by hand sanding.
Sheet sanding
This sanding machine uses a repeating pattern to move the sanding pad. This tool is adequate for most initial sanding tasks. The machine uses ¼ or ½ sheet of regular sandpaper, which makes it more economical than orbital sanders as they require specific sanding disks.
How To Start Sanding Wood
Choosing the Right Sandpaper
The very first thing about sanding is to select the correct sandpaper or sand disk suitable for your project.
You might come across different types of sandpaper with a label of 80-grit, 120-grit, 200-grit, etc. The number and grit indicate the sanding granules per square inch of the paper. A higher number means the sandpaper is of more elegant grade and can perform finer and more delicate tasks.
On the other hand, lower grade sandpapers are coarser type.
For refinishing furniture and antiques,
People generally use a medium to an excellent grade of sandpaper. Under 100-grit sandpaper can damage the finish of beautiful wood. 120-grit and 150-grit sandpapers are ideal for removing scratches and old finish.
220-grit sandpaper is considered as finer grit, and it is used for light sanding right before applying the satin.
Sanding Wood Using an Orbital Sander
If you prefer sanding wood using a machine, for most circumstances, an orbital sander will do the trick. You need to choose the sandpaper depending on the condition of the wood surface. Use 80-grit sandpaper if the surface is very rough, use 120-150-grit sandpaper for a smooth surface, and use 220-grit sandpaper to make the surface even more seamless.
Now, attach 80-grit sandpaper to the orbital sander to sand the rough woody surface. Remove the sawdust from the wood using a cloth or compressed air.
Some roughness left
There will be some roughness left by the 80-grit sandpaper. Therefore, the next objective is to sand away that roughness by a 120-grit sandpaper. It will not take too long as the previous sandpaper. You will be able to feel the smoothness of the surface when it's done. Remove the sawdust when sanding is finished.
Again, attach a 180-grit sandpaper to the tool and start sanding. It will make the surface even smoother. You will feel the noticeable difference in the wood.
After achieving such a level of smoothness,
Your wood is ready to get some finish or stain on it. Although power sanders save time and effort, they have disadvantages as well. Power sander leaves curly marks on the surface, and you will not be able to notice the marks until it's time for applying the final finish.
Avoid Curly Marks Created from Power Sanders?
One drawback of using power sanders is, they can create curly marks on the surface which are nearly impossible to detect while sanding. This can cause you to re-sand the entire project and re-apply the finish on it.
Follow the instructions below to eliminate these curly marks:
How to Sand Wood by Hands?
Using hands to sand wood requires different equipment. You can sand using a flat sanding block, and a quarter sheet power sander. Both have a field of expertise with pros and cons.
If your wood surface has curves, softening corners and edges, you can go without using a sanding block. But when you deal with flat surfaces, make sure you use a sanding block, which is available in local hardware stores.
Be sure to attach a soft layer like the corkboard to the sanding block's face. It's not necessary, but helpful.
Now, onto the sanding.
Get a flat block and hold it against your sanding block. The flat block should be opposite to the wood surface. Sanding block needs to face the edge of the wood. Furthermore, sand back and forth to the direction of the wood grain.
Sanding across the grain will result in sanding marks at the end, and you will need to remove the marks using an 80-grit sandpaper and further sand using finer sandpaper to smoothen the surface.
How to Sand Rougher Wood?
When it’s about sanding more rough wood, it’s pretty much the same. But it’s worth talking about some tips regarding it to make the process efficient.
Rougher wood requires coarser grit to start the process. Wood that has not been sanded before is more uneven than wood that has been through a sanding process previously. Using an 80-grit sandpaper will bring good results in this case.
As the surface has not been sanded,
The sanding process will take a long time to finish. You must make the surface flat. Using a power sander will do the work much faster, but you can use your hands as well. If you sand the wood with a 120-grit sandpaper at first, there will be slight hills and uneven areas across the surface.
So, you will need to sand it further with an 80-grit sandpaper, which will be more time consuming and tiring. Therefore, you better start sanding by 80 grit sandpaper from the beginning even though it takes time.
When you are done sanding, you will find that the surface is flat and smooth to touch. You need to check whether there are still any uneven areas or hills on the surface.
To do that,
Use a flashlight and hold it at a low angle, then check across the wood in different directions. Uneven and hilly areas will be identified easily. To eliminate those uneven areas easily, take a pencil, and draw lines in those areas.
Further sand across the board until you erase pencil lines by sanding. When the lines are gone, the surface is adequately sanded without any high areas.
At this stage of sanding,
remove the sawdust to avoid subtle pitfalls. Using compressed air, or vacuum, or brush will do the trick here. To make the surface more appealing, be sure to remove dust using a tack cloth. Now, you can advance through various grits of sandpaper until you get the desired finish.
Depending on the application, some will end at 120 and some at 220-grit sandpaper. The process will not take long as before when you went through different grits. That's because you have already flattened the surface using an 80-grit and even smoothen it using the pencil method.
You can use the pencil method for each grit sandpaper to get a more delicate finish. The pencil marks will get lighter as you proceed to the higher grits.
Pro Tips for Sanding by Hand
