When it comes to refinishing painted wood surfaces, choosing the right grit sandpaper is crucial. The wrong grit can damage the surface or make it difficult to achieve the desired finish. In this article, we'll discuss the different grits of sandpaper and which one is best for sanding painted wood.
What is sandpaper grit?
Sandpaper grit refers to the number of abrasive particles per square inch of sandpaper. The higher the number, the finer the grit. For example, 80-grit sandpaper has fewer abrasive particles than 220-grit sandpaper.
What grit sandpaper for painted wood?
When sanding painted wood, it's best to start with a coarse grit sandpaper and work your way up to a finer grit. This will help to remove any existing finish and smooth out any imperfections. The grits you'll need will depend on the condition of the surface and the desired finish.
For initial sanding or removing paint drips and bumps, start with 80-grit sandpaper. This grit will remove the old paint or finish quickly but can leave behind noticeable scratches. After the initial sanding, move up to 120-grit sandpaper to smooth out any rough spots and scratches.
If the surface is already fairly smooth and just needs a light sanding before repainting, start with 120-grit sandpaper. This will create a smooth surface without damaging the existing finish. For a very smooth finish, move up to 220-grit sandpaper.
Choosing the right grit sandpaper for painted wood can make all the difference in achieving a smooth and professional finish. Starting with a coarse grit and working your way up to a finer grit will help to remove any existing finish and smooth out imperfections. Use 80-grit sandpaper for initial sanding, 120-grit sandpaper for smoothing out rough spots, and 220-grit sandpaper for a very smooth finish. With the right grit and technique, your painted wood project will look great for years to come.
