4 Methods to Sand Walls Quickly

The process of sand walls does take quite a long time and wastes a lot of energy. How could it not be, you have to sand all the corners of the room until it’s smooth so that the wall paint can stick perfectly. What’s more, sanding the wall also cannot be tried haphazardly. Using the wrong sanding method will actually make the wall surface continue to be aggressive and full of strokes.

If you are in the process of painting the walls in a house or individual building, you don’t really need to hire a handyman. You can do it yourself using the following 4 quick methods of sanding walls.

Sand Walls


Prepare supplies and equipment


If you want to use the fast wall sanding method, first you have to prepare all the various tools and equipment. For manual work, you need a sandpaper handle to make the process easier and faster. However, you can also use electric sandpaper so that sanding can be even faster.


Don’t forget to fill yourself with glasses, masks, and hats. The method of sanding walls quickly will, of course, create more dust and wall debris which can harm your health. Move all the various furniture in the room first, cover the floor with newspaper so that dust and debris can be easily cleaned. That way, sanding the walls doesn’t take much time either.


Selection of fine sandpaper


Many people think that aggressive sandpaper is better and faster. However, this assumption is wrong. Indeed, there is nothing wrong with using aggressive sandpaper, but this aggressive sandpaper can actually disturb the walls in your home. It is advisable to choose fine sandpaper with a grit of 120 to 150 as a method of sanding walls quickly. Especially if you are still a beginner, it will be easier to use fine sandpaper.


Avoid brushing the sandpaper in a vertical or horizontal motion because it can create aggressive streaks on the surface of the wall. Instead, use a circular motion when sanding. Don’t sand the same spot on the wall over and over again. Whether using manual sandpaper or electric sandpaper, you don’t need to squeeze the sandpaper with a lot of force. Just allow the mass of the handle of the sandpaper or electric sandpaper to work.


Don’t forget to change the sandpaper periodically. If the results of sanding the walls are felt to be less than optimal, it is a sign that the sandpaper has continued to thin out. Replace with a new one as soon as possible and continue sanding the walls again.


Use bright lights


Even if you use the fast sanding method, it doesn’t mean that the quality of the sanding results is reduced. To ensure that there are no spots in the room that are left behind, use a flashlight as a lighting bonus. That way, you can easily create spots on the wall that haven’t been sanded yet.

This method is effective for reducing the duration of wall sanding because you no longer need to re-check. Then, using a flashlight, you can also make small holes in the wall that need to be filled again with gypsum or plaster.

Plamir the wall and sandpaper again

Often what happens when repainting the walls of a house is that the walls still look aggressive and there are lumps of wall paint. Meanwhile, the walls had been sanded repeatedly before being painted. This happens because you don’t plaster the wall and sand it back down. As a result, the wall also does not look perfect and must be repainted. So work 2 times, wasteful time and energy.

Therefore, the method of quickly and correctly sanding the wall is by plastering the wall before sanding it again. First of all, you always have to sand the wall before plastering. After that, plaster the wall and sandpaper again to smooth the texture of the wall which is still visible due to plastering.


That way, the walls also appear smooth and free from clumps of paint. What’s more, the paint on the walls also becomes more durable, so you also save on home maintenance costs.
