What Grit Sandpaper to Remove Varnish from Wood? – Guide
Grit sanding is great for getting rid of the protective finish on the wood. For best results, you should use medium or coarse sandpaper. However, this guide helps you to select the right grit sandpaper:
Understanding Grit Sandpaper
Grit sandpaper refers to the abrasive particles that are embedded in the sandpaper itself. These particles come in different sizes, which are measured in grits.
The higher the grit number, the finer the abrasive particles and the smoother the surface the sandpaper can create.5
Conversely, lower grit numbers have larger abrasive particles that are better suited for rougher surfaces and material removal.
Choosing the Right Grit
Sandpaper to Remove Varnish from Wood When it comes to removing varnish from wood, you’ll need to use a range of grits to achieve the desired result.
The ideal grit sandpaper to use depends on the condition of the wood and the thickness of the varnish.
For rough or thickly coated surfaces, you’ll need a lower grit sandpaper to start. We recommend starting with a 60-grit sandpaper, which is coarse enough to quickly remove the top layer of varnish, without being too aggressive and damaging the wood.
It is also important to note that using too high of grit sandpaper in this initial stage will cause the sandpaper to clog and reduce its effectiveness.
Once you have removed the top layer of varnish with the 60-grit sandpaper, move up to 100-grit sandpaper to remove any remaining varnish and smooth out the surface.
Finally, use 150-grit sandpaper to get a smooth, even finish that is ready for refinishing.

Sandpaper vs. Other Methods of Removing Varnish from Wood
While sandpaper is an effective way to remove varnish from wood, there are other methods to consider.
Chemical strippers, for example, can be used to dissolve the varnish, making it easier to scrape or wipe away.
However, chemical strippers can be messy and require careful handling, as they can be toxic if ingested or inhaled.
Heat guns can also be used to soften the varnish, making it easier to scrape away. However, heat guns can be dangerous if not used properly and can damage the wood if left on for too long.
Ultimately, the best method for removing varnish from wood depends on the condition of the wood, understanding sandpaper grit, the type of varnish, and your level of experience with different techniques.
If you are unsure, we recommend starting with sandpaper and gradually working your way up in grit size until the desired result is achieved.
Sandpaper Techniques for Removing Varnish from Wood
Using sandpaper to remove varnish from wood requires some skill and technique. Here are some tips to help you get the best results:
- Always sand in the direction of the grain. Sanding against the grain can create unsightly scratches and marks that will be difficult to remove later.
- Start with a lower grit sandpaper and gradually work your way up to a higher grit. This will help prevent damage to the wood and ensure a smooth, even finish.
- Use a sanding block or an orbital sander for larger surfaces. This will help distribute the pressure evenly and prevent uneven sanding.
- Be sure to wear eye protection and a dust mask when sanding. Varnish dust can be harmful if inhaled or ingested.
- Keep the sandpaper clean and free of debris. Wipe it down frequently with a rag or use a sandpaper cleaning tool.
