How To Sand Small Crevices?

Sanding is an integral part of woodworking. It is the process where the wood gets the polishing and the finishing using an abrasive like sandpaper. The purpose of sanding is to efface the nicks and scratches from the wood’s outer layer. This might sound fairly easy. Sanding is easy, but it requires a lot of patience and maneuvering skills.

If you are working on a project, you won’t be dealing with plain surfaces all the time. At times you might end up sliding towards crevices in the wood. If not taken care of the nooks, the outlook will not be as pristine, as simple as that. This is where things might get complicated and you must know how to sand small crevices

No worries, there are solutions to this problem. You can perform wonders by yourself. We are here to guide you with some necessary steps for untroubled sanding work.

To successfully work on small crevices, you must do the following things.

Step 1: Choose the Best Sanding Material

This is the most important phase. Getting the right sanding material is the key to unblemished woodwork. We prefer quality sandpapers. You must keep in mind that there are variations in sandpapers as well. 

Sanding Blocks

These are like bricks, but the whole body is a sanding material. Sand blocks can put sufficient pressure on the working surface and due to the flat surface, it is a good sanding material. You can customize the block on your own rather than buying one. Use a comfortable but heavy block. Paste sandpaper on the bottom, and make sure they stick firmly. There you go, you have a sanding block.


Certainly, the most commonly used material when it comes to smoothing a wood surface. You can also find foldable sandpapers which are more flexible and reach tighter spaces when affixed with external tools. Sandpapers come in different grits. You must always purchase a paper that has a higher grit number. 

60 to 80 grit sandpapers are used mostly to clear off the surface to a bare minimum. It is not suitable for shaping, carving, and stripping paints.

100-150 grit papers are best suited for general sanding tasks. It can be worked extensively to furbish the woods.

180-220 grit sandpapers are ideal for working on rough surfaces. They will give you a sleek and finer finish.

Then we have 300+ ultra-fine grits that are used for buffing.

Step 2: Handed Sanding Equipment

Get hold of a good-handed sanding device. This device is used for flattening the surface of the wood.

Step 3: You Need a Foam Pad

Here you will need flexible foams to line up a pad. Make sure you adjust the padding according to the shape of the sander. 

Step 4: Sanding Grips

Sanding materials are rough as well as sharp, they can scratch your fingers. To protect your fingers from accidents, use a contoured sanding grip for your safety.

Step 5: Stick the Sandpaper to a Knife

This is where you paste the sandpaper on a knife or long carrying tools. Why knife-like objects? Because such tools are likely to reach the small crevices and corners. We prefer you use folding sandpaper, this can be easily bent and attached to the object. 

The sandpaper you use on the knife is crucial. You might want to get a paper that can be used over time for about 4-5 rounds, rather than single-use. Clog-resistant papers are the best solution instead of the aluminum oxide ones. 

Step 6: Start Sanding With the Knife

Now it is about physical work. Reach the small crevices with the sandpaper-covered knife and keep working on it to get the desired outcome. Reach corners if needed. Keep on rubbing against the crevices until you get what you want. Easy peasy!

Step 7: Use the Sanding Block if You Prefer

You can use the sanding block or the sandpaper-coated foam over the molding if the knife technique is not necessary.

Are the Above Steps Really Useful?

Using your hand gives you better access to the crevices. More importantly, you are in control of the situation and you get to decide how much polishing and smoothing the surface needs. 

We feel the hand technique is more reliable than power sanders. It gives you better control while woodworking on small crevices. 

With technology, it gets easier to reach tighter spaces. You can use sanding blocks, sandpaper-coated knives, sanding sponges, and many other sanding materials other than expensive power tools. The options and steps mentioned above are all functional and best suited to woodworking. 

How do Sand Small Crevices with Power Tools?

If you are in a hurry and want to work faster than the manual steps. You can use a power sander. These are fast and viable tools for sanding. To reach crevices you can use different types of sanders. 

Detail sanders are designed in a triangular shape to reach intricate corners. File sanders are designed with narrow belts to get into tight spaces. Rotary tools can be used by putting the desired shape materials on the front part. The oscillations from this device are supposed to do the trick, reaching crevices. Spline slides can be used to reach complex grooves on the furniture. 

Power tools are good alternatives if you have the budget or simply if you feel lazy working with your hands manually.
