Best Sanders for Stair Sanding

Here I’ll show you the top 5 best sanders for stairs, each with an introduction to their type (sheet, orbital and detail).

Top 5 Best Sanders for Stairs

Sheet Sanders for Stairs

The classic choice. Offering you a square or rectangular sanding pad that perfectly fits most stairs coupled with a compact and easy to maneuver body, sheet sanders are the most popular option for this type of work – you can’t go wrong with these. They’re a great stand-alone choice for most cases but if your stairs have a corner angle that goes above or below 90 degrees, then you’ll need a detail sander as well to ensure you can sand them.

Orbital Sanders for Stairs

As versatile as can be, orbital sanders are the Swiss army knife of the sanding world and as you’d expect, they can take on stairs as well. While they can deliver excellent results, the shape of the stairs is crucial here because due to their circular pad they might not be able to reach the corners. If you’ve got a detail sander to accompany one of these though, you’re on your way to perfection.

  1. Hello, please could you recommend a block sheet sander that isn’t too heavy to sand the stair risers. I’m thinking of hiring something as only a few stairs to complete. Also which is best to purchase. Cord or cordless. The mouse sander used hasn’t been able to get into the corners of the treads and the large edger is to heavy to hold up to do the risers!!!! Thank you.

    • Hey Carole,
      For the risers, the Makita BO4556 would be a perfect fit – it’s small and lightweight while still being potent and highly effective. To get the corners the BLACK+DECKER BDEMS600 is the best choice as even if the regular shape can’t reach a tight corner, the tip expands into a precise sanding “finger” that can reach anywhere with ease. When it comes to cord vs cordless, it’s all about personal preference and type of work. I’d always go with corded tools for more demanding or long tasks but if it’s a more casual or quick ordeal then the cordless variety would be a great fit. Hope that helps Carole and good luck with the stair refinishing!

  2. Hi just came across your site and it has a lot of great information…thank you for sharing. I do have a question though. I have a staircase which consist of two open stringers and treads with carpet wrapped around them. The treads butt up to the wall on one side and are open on the other side all four sides of the tread are rounded. Could you advise best sander to tackle this I know at this point the edge against the wall will require hand sanding. Also could you advise proper sandpaper grades to use the stairs current have a clear stain. When finished I hope to paint the strings and do a dark stain on the treads.

    • Hey Mike, taking into consideration the details of your staircase, I’d go with a random orbital sander – they’re the most versatile type of machine and they’ll guarantee that everything gets smoothly sanded even if rounded, at an angle or hard to reach. In the end, just as you mentioned, I’d definitely give a manual finish to all the pesky edges to ensure I get a perfect result. Since they currently have a clear stain I’ll imagine the stairs are in pretty good shape – if this is the case, you can skip the rougher grits and go right to around 80 or 120. It’ll not only make the whole process faster but it also ensures that you eliminate the old clear stain without damaging the wood’s grain or integrity. After that, you can either go right to staining or, if you want a highly polished look, you can move on up to a very fine grit like 200+ and perform another pass.

      Hope that helps Mike and I wish you the best of luck with the renovation!

  3. I enjoy watching flipping shows like Stone House Revival, Rehab Addict and Home Town. I love old wood and enjoy watching them repair and rebuild trim, doors, floors and built-ins bringing them back to their former glory. Now I would like to stain and refresh my wooden stair railings. I found your site when researching electric sanders and wood finishes.
    I am thinking of using dutch oil for a finish and a palm sander. What would you recommend for my first project.

    • Hey Kathleen, you’re not the only one – it’s always satisfying to watch experts take an old piece of wood and breathe a new life into it. For your stair railing renovation, Dutch oil is a great choice as you can’t go wrong with it, it always looks beautiful. When it comes to the sanding machine, you’re also spot on – a palm sander is nimble, small enough to fit anywhere and produces great results without tiring your arms which is great when dealing with railings. I recommend that you go with a circular orbital palm sander due to their outstanding capability of producing an excellent, scratch-free finish, even if you’re an absolute beginner. The DEWALT D26453K shown above is great, and so is the Bosch ROS20VSC, you’ll be well armed with either one of them.
      Hope that helped and good luck with your very first project Kathleen, have fun!
