When it comes to painting with oil-based paint, proper surface preparation is essential to ensure a smooth and long-lasting finish. One crucial aspect of surface preparation is sanding. Sanding helps to create a smooth and even surface for the paint to adhere to.
But what grit sandpaper should you use for oil-based paint? The answer depends on the condition of the surface you are painting and the type of finish you are looking to achieve.
If you are starting with a relatively smooth and even surface, such as a previously painted wall, you can generally start with medium-grit sandpaper, around 120-150 grit. This will help to rough up the surface slightly, providing a better feeling for the paint to adhere to.
However, if you are working with a rough or uneven surface, such as a wooden fence or furniture, you may need to start with a coarser grit, such as 80 grit. This will help to remove any rough spots or imperfections on the surface, creating a smoother finish.

After you have completed the initial sanding with the coarser grit, you can move on to finer grit sandpaper, such as 220 grit. This will help to smooth out any rough areas left by the coarser grit and create a surface that is ready for painting.
Remember always to wear protective gear when sanding, such as a dust mask and safety glasses. Additionally, be sure to clean the surface thoroughly after sanding to remove any dust or debris before painting.
In conclusion, the grit sandpaper you should use for oil-based paint depends on the condition of the surface and the type of finish you are looking to achieve. Generally, a medium-grit sandpaper of around 120-150 grit is suitable for previously painted surfaces, while rough or uneven surfaces may require a coarser grit, such as 80 grit.
