Can I pour concrete on my main floor of my house?

You wouldn't want to pour the SLC tight against the new wood floor. So, you could use a foam sill seal laid up on edge that will later be removed after the SLC has had time to set. This will leave a small 1/8" gap to accommodate expansion and that gap can then be caulked with a latex caulk to match the wood floor color.

After the SLC is in place acid staining can be done but this will require some serious masking of the new wood floor and lower walls and anything that can be splashed during the process.

I would suggest you visit the Mapei International website and research their Self Levelling Compounds used for a wear-surface. Regular SLC's won't work. Then take a look at the website of Gaye Goodman to do a little research on acid staining.
I checked out their website. Their are a lot of floor leveling compounds, but they all appear to be underlayment specifically stating that they are only for underlayment. They have one specifically for wood substrates, but it is unclear if it can be used as a finished surface. Which did you use? Any thoughts.

I did find this.....

That is a long story, a lot of steps and a lot of work. This might get a little long, so be warned.

I cut a thin strip of 2x4 on edge (1/16" thick) to use as a flexible design tool to lay out the curve I wanted (this turned out to be the best way after numerous other ideas). I also used a string wrapped around the fresh air intake for part of that curve. I found the curve I like and put a few nails in to hold it in place to trace it.

After I had the curves I wanted, I scribed the curve onto 1/2" mdf to use as router guides the cut the curve. I cut out the router guides meticulously (band saw, oscillating sander).

I used double sided tape to tape them around the curve and used the router along it to cut the curve out with a spiral bit.

Once the curve was cut, I scribed the curve again in the other direction onto more 1/2" mdf so I could make router templates to make the curved cherry border pieces. This took forever and was a massive pain in the ass, but I couldn't come up with a better way. I fit them little at a time continually shaping them by hand (band saw for rough, oscillating sander for fine, and rasp for perfection fitting).

Once the templates fit perfectly, I traced them onto 3/4" cherry, roughly cut out the shapes within 1/16-1/8". Then I nailed the templates to the underside of the 3/4" cherry and used a flush cut bit with a bearing in the router table and cut the cherry exactly as the template pieces.

Yes, there's more.

Then to attach the border pieces to the floor, I used my biscuit jointer to cut biscuits into the floor and the border pieces. Glued those in place (I debating letting them float with no glue but decided on glue to minimize movement - I may regret this if there is movement between the species and something splits - time will tell here)

I then pre-drilled and countersunk trim head screws into the outside edge of the pieces to hold them down on that side (they are not on the faces of the border pieces but diagonally on the edge that will be covered by the poured floor)

And done. Very long project that I really enjoyed as it was a massive challenge for me from start to finish. Challenge being fun and good. It was solvable, just took a lot of thought and ideas - some worked, some didn't. I like that kind of project. I'm no pro, just a hobbyist. I just like working with wood and figuring out that kind of stuff.

All of those products are suitable for underlayments but when you look closely you find that some are suitable for foot traffic and light wheel traffic. Ultraplan M20 Plus is the product to look at closer. Mapei has more than one but I didn't spend a lot of time looking for them.

Never heard of that product but that doesn't mean it wouldn't be the one to use in your case.

There are also important highlights to preparing for installing Self Leveling Compounds and I have some additional information in a two-part Blog around here somewhere.
