When it comes to painting a surface, proper preparation is crucial to achieving a smooth and long-lasting finish. Sanding is one of the most important steps in the preparation process, but how much sanding is necessary before painting?
The answer depends on the condition of the surface you are painting. If the surface is in good condition, with no peeling or flaking paint, a light sanding with fine-grit sandpaper (220 grit or higher) is usually sufficient. This will help to smooth out any rough spots and provide a slightly rough surface for the paint to adhere to.
If the surface is in poor condition, with peeling or flaking paint, you will need to do more extensive sanding to remove the old paint and create a smooth surface for the new paint to adhere to. In this case, you may need to use coarser sandpaper (such as 80 grit) to remove the old paint, followed by finer sandpaper to smooth out the surface.

It's important to note that excessive sanding can also be problematic. Sanding too much can create a surface that is too smooth and glossy, making it difficult for the new paint to adhere properly. In addition, sanding too much can also damage the surface and create an uneven finish.
In general, a good rule of thumb is to sand enough to smooth out any rough spots and create a slightly rough surface for the paint to adhere to. If the surface is in good condition, a light sanding with fine-grit sandpaper should be sufficient. If the surface is in poor condition, you may need to do more extensive sanding to remove old paint and create a smooth surface for the new paint to adhere to.
So, how much should you sand before painting? The answer is: it depends. Assess the condition of the surface you are painting and use your best judgment to determine how much sanding is necessary for a smooth and long-lasting finish.
