Furniture restoration is an art that combines patience, skill, and the right tools. One of the most essential tools in this process is Sandpaper. Whether you’re stripping old paint, varnishing, or preparing wood for refinishing, Sandpaper plays a crucial role. However, choosing the right grit sandpaper can be challenging, especially for beginners. If you’re wondering what grit sandpaper for stripping home furniture is best, this guide has all the answers.
Understanding Sandpaper Grits: What They Mean and Why They Matter
Sandpaper grit is a term that refers to the coarseness or fineness of the abrasive particles on the Sandpaper. These particles are responsible for smoothing or stripping surfaces. The grit number on the Sandpaper tells you the size of the particles: the lower the number, the coarser the Sandpaper, and the higher the number, the finer it is.
How Sandpaper Grit Works
- Coarse grits (40-60 grit): These are aggressive and great for removing thick layers of paint, varnish, or other finishes.
- Medium grits (80-120 grit): These are versatile and used to remove residue left by coarse grits or smooth rough surfaces.
- Fine grits (180-220 grit and above): These are designed for smoothing wood and preparing the surface for finishing.
Why Sandpaper Grit Matters
Using the wrong grit can lead to problems:
- Too coarse: It may damage the wood, leaving deep scratches.
- Too fine: It can clog quickly and make stripping paint or varnish inefficient. Understanding the grit scale ensures you choose the right Sandpaper for each stage of furniture restoration.

Best Grit Range for Stripping Furniture
- Coarse Grits (40-60):
- Ideal for heavy-duty stripping tasks.
- Removes thick layers of paint or varnish efficiently.
- Use with caution to avoid gouging the wood.
- Medium Grits (80-120):
- Perfect for tackling leftover residue after coarse sanding.
- Smooth rough spots and start to prepare the surface for refinishing.
- Fine Grits (180-220):
- Used for the final preparation of the wood surface.
- Ensures a smooth finish, ready for staining or painting.
Why Start Coarse and Transition to Fine
Starting with a coarse grit quickly removes most of the old finish. Transitioning to finer grits smooths out the scratches left by coarser Sandpaper, leaving the wood ready for a new coat of paint or stain. Skipping these steps can result in uneven surfaces or poor adhesion to the new finish.
