Sanding is often considered the most important finishing touch for any wooden project. Sanding is commonly considered to be the most important step in finishing a wooden project. This is because the rough fibers are scraped away by friction when sanded. Also, this is an effective way of smoothing out edges and flat surfaces. The process gets its name from the fact that 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. After sanding wood, it is important to clean the surface thoroughly. Sanding can be messy and can leave a lot of dust behind. Dust can scratch the wood’s surface, which is why it is important to clean the wood thoroughly after sanding. Let’s take a 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 bubbles under the paint. As a result, it accelerates the paint’s deterioration.
What About Only Cleaning the 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 applying 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.
