How to Clean Wood After Sanding Before Painting – Proper Ways

Sanding is often considered the most important finishing touch for any wooden project. The reason is that it scrapes away the rough fiber by friction. It excellently smoothens out sharp edges and flat surfaces. The process is called sanding because the main element used for wearing out the fibers is sand.

Before staining or painting, sanding is very important; otherwise, they would not stick to the wood properly. If anything is more important, it is to clean the surface thoroughly after sanding as the process accumulates a lot of dust. The stain or paint would not last long if the surface is not cleansed.  Let’s take to look at how to clean wood after sanding.

Do I Need To Sand Wood Before Painting?

You should sand the surface before painting. Some might say it is not absolutely necessary. They are right in their own way. For some types of paint, only cleansing the surface is good enough. But if you want the best result, then you should definitely sand the wood before painting.

What basically happens is that sanded wood contains a minimum amount of dust. So, the paint gets into direct contact with the surface without getting a dust layer in between. Having a layer of dust in between, traps air bubble under the paint. As a result, it accelerates the paint’s deterioration.

What About The Only Cleaning Wood Before Painting?

If you decide to only clean the wood without sanding, then you will need to follow other means. You could use a pre-paint cleaner to thoroughly clean the surface. Because only brushing won’t be enough to clean the dust laying in between wood fiber.

Another way could be applying primer first, then apply paint on it. The primer will help to hide joints, holes, seams and etc. On top of that, the paint really sticks well on the primer.

Another easy option could be to use chalk paint. They require minimum prep work. It not only sticks well to all surfaces but also you could use it as a chalkboard. But it is understandable not to like the chalkboard feel on the wall.

Apparently, you have a few tricks up your sleeve if you want to avoid sanding furniture or wall. FYI, there will be a significant difference between the paint on sanded wood and not sanded wood.
