Types of Sander Used for Stairs
Stairs are mostly rectangular in shape with an enclosed corner on one side. Some stairs have wide angles as well. Now, to sand a stair case, choosing a sander with square or triangular shaped pad is more logical than choosing one with circular pad. I can’t say, which one you must use and which one not. Rather, I will discuss all these types so that you will gen the pros and cons of each type sander.
Finishing sander/Palm Sander
These are square pad sander that moves on orbital motion. These are the best kind to sand a stair. These are small, compact and never leaves any corner untouched. Besides, these are powerful also, which is suitable for hardwood stairs.
This sander has a triangular pad and also moves on orbital motion. These are great to reach any spot easily and are more suitable for stairs with wide angles. Detail sander are less powerful and the pad is smaller than square ones. So, it may take longer to complete the project.
Random Orbital Sander
The last one option for sanding a stair case should be an orbital sander. The pad is circular, hence, the corners will be left to be polished manually. But these sanders are all-rounder and can be found in any homeowners tool box. So, you can use it on stair too, but remember to touch up the corners manually.
Paper attachment system are mostly two types for palm sanders. Clip system and loop system. The loop system is more secure but takes time to change paper in between your tasks. On the other hand, the clip system is easier for paper changing. There are sanders available that that takes both type of paper. Choose one based on your preference.
The power require for sanding the stair highly depends on the type of wood used for the stair. If it is a hard wood stair, then the more power full the sander is the better. Otherwise, a moderate one will do the job.
Take into account how the sander fits in your palm and how noisy of vibrating it is. All these matters when you have to work on a large project. These sanders are held by hand for a long time. A wrongly choose one can make you take break frequently and can lengthen the task.
If you have gone through all the top rated sanders I have chosen for you and the guideline to choose one for your project, then you already got the idea how to choose one for yourself. Sanding a stair is no big deal if you got the right tool in your hand.
