How to refinish stairs that were carpeted if the underlying wood is in bad shape
Supplies needed to refinish the wood treads
- wood filler (I love this one HERE or HERE)
- spatula (HERE)
- tinted stain (We will get to what I used in a bit but if you want to use something different than me then you could use this one HERE)
- Spar urethane or any other clear protective coat of choice (I used this one HERE and I prefer satin finishes)
- brush made for oil-based paints and stains (HERE)
- small roller, handle and tray (I love these HERE and this Roller HERE)
- sandpaper (HERE)
- numerous pieces of tack cloth HERE (To me the most important item in the project)
- facemask/respirator and filters HERE and HERE
- painters tape
- Paint of your choice for stair risers. I use one specific paint for that in my entire house for white kitchen cabinets, trim, molding and in this case the risers and sides. It is made by Benjamin Moore and is called INSL-X Pro Cabinet Coat (click HERE). You can read more about how I also used it on my kitchen cabinets HERE.
How I picked my stain color
I don’t know if you remembered that I had the problem of making the downstairs maple flooring somehow transition with the upstairs light gray bamboo flooring. And also hide the cheap and damaged wood on the stair treads (click HERE if you missed my first post). So I bought several sample cans of tinted stains to test out.
When I walked the aisle at the home improvement stores and browsed online I noticed the color limitations. There was nothing that resembled the light gray floors upstairs in any way. I had pondered going with a black stain and bought one to try out…PolyShades satin classic black & polyurethane (HERE) which is stain and protective coat all in one.
I also bought several other gray stain samples because I already knew that the black stain wouldn’t make me happy. Dirt, dust, and hair tend to show up more on dark finishes.
I bought from left to right: Behr Premium Waterproofing Stain & Sealer Semi Transparent (ST-125 Stonehedge), Varathane Wood Stain in Weathered Gray (HERE), Behr Premium Waterproofing Stain & Sealer Solid Color (SC-149 Light Lead and SC-365 Cape Cod Gray)
And yes outdoor wood/deck stain snuck into my cart because I just loved the color variety but that’s where the story gets interesting or should I say iffy! The options were so much better and closer to our gray floors upstairs. They were also either semi-transparent or solid. I wanted something that would hide the awful imperfections of the cheap wood and the damage the carpet staples had done to the treads.
Like you see in the above photo I applied the stain samples to pieces of wood so I could test them out. I liked Behr Premium Waterproofing Stain & Sealer Solid Color in SC-365 Cape Cod Gray the best and I was questioning if I could use the outdoor stain inside the house.
Did you see all the scuff marks and dirt above? my stairs were in bad shape again since my last post.
So I started to do some research on outdoor stain usage inside the house because of the fact that I liked the outdoor stain so much better.
Outdoor Deck Stain on Indoor Stairs
Now let me get into this controversial topic of using outdoor stain inside your home a little more and the reasoning why I chose to go this route even. I did my research and based my decision on that. I’m not a professional and will not be held accountable for anyone else’s decisions.
Main Concern: Toxicity of outdoor stain
Well, let me say that both indoor and outdoor wood stains have some level of toxicity due to fumes and chemicals added to protect the wood. Exterior deck stains often incorporate additional chemicals, such as fungicides, preservatives, and pesticides.
But indoor stains are also still toxic and also contain some amount of volatile organic compounds or VOCs. You should definitely always read the manufacturer’s labels.
Even if you use indoor stain, you should never inhale the fumes of the stain and should always use a protective respirator.
Benefits of Outdoor Stains:
A larger variety of colors and various levels of transparency of the stain to even being completely solid.
Outdoor stains are also made to be more durable since they have to withstand the elements to protect the wood.
Why I chose and justified to go with outdoor stain for staining stairs
- The area of the stair treads I needed the stain for is minimal (I only used two small sample cans, that’s it, which ended up being around $7)
- Great durability of the product.
- I used a mask while using the outdoor stain, opened all the windows and made sure my cats and children weren’t around.
- Nobody is ever concerned about walking around barefoot on decks that are stained with these types of stains, so I figured we’d be ok to occasionally walk on stair treads that are covered in the outdoor stain. I would have never used it on my entire indoor flooring!
- Another major reason is that I was just very curious to see how this stuff would work on my stairs.
- If it didn’t work out I could still use stair tread overlays to cover my failure (click HERE, I love them but they are super expensive)
- Possibly coating the stain with a protective sealer although it’s not required will seal everything whether it is indoor or outdoor stain.
- The color options were just right. I looked at everything they had at all our home improvement stores and there was nothing I liked that qualified as an indoor stain. None of the colors and finishes would have tied in our grey bamboo floor with the stair treads.
Staining Stairs Process
The most important part of how to refinish stairs that were carpeted is as always cleaning the stairs thoroughly before applying any product. To me, the most important little tool is the tack cloth because even after vacuuming and cleaning the stairs I still got a huge amount of lint on the cloth. Had I not used the tack cloth, all that lint and dirt would have ended up in my stain and paint.
Sorry for the blurry photo 😉
For painting the white risers I love using the small rollers that I mentioned in my supplies list. They work really well with my favorite white paint. I use the rollers on the risers and a little bit on the sides and I cut in and painted the rest with my good brush.
Just look at the bad shape the stairs were in:
I mentioned painters tape for people who like to tape before painting. I personally just cut in freehand with a good brush now when I paint certain projects. This one was one of those projects.
And before cutting in and painting in each stair tread, I made sure to use the tack cloth again.
And here is the view we have right now with the gray outdoor deck stain and the gray bamboo flooring.
Around that corner, it goes up another flight of stairs. So it would have been natural wood downstairs, gray wood on landing, natural wood again on another set of treads and gray wood again upstairs… which is why I wanted to make the transitions flow better somehow.
Before and after to show you how it ties in with the gray floor which is Pearl City Click Bamboo by Lumbar Liquidators by the way.
This is not where this story ends though. I would have loved for the stair treads to remain natural light wood like the downstairs flooring. It just didn’t look so good because of the quality of the wood and how damaged it was.
I did, however, figure out a way to incorporate some more natural light wood in this stair makeover. It will tie in with the gray floor when you look down from above. Also, if you look up from down below you will be able to see the light-colored wood. I’m just waiting for the materials to arrive and am hoping that the rest of the project will work out.
