For the application of OSMO flooring products you can either just apply the Polyx Oil for a natural finish or you can apply the colored OSMO Wood Wax first to work as a stain. We did two coats of the Wood Wax and then two coats of the Polyx Oil (which ultimately was probably overkill.)
We used the Pine color for the Wood Wax

Here is a link to the official OSMO instructions for applying the Wood Wax Finish. We purchased a gallon of the product for about $100 (which will likely do most of the house) and an 220mm OSMO applicator brush for about $44. We purchased all of our supplies from the Amicus Green Building Center in Kensington, MD.
The brush did not come with a handle and it is not a "screw in" model - rather it requires a wood handle that you then use a little screw to secure it. We had a broken rake so we just took the wood handle off of that - gotta work with what you've got!
Then we opened up our can and stirred well!
Poured the Wood Wax Finish into a clean paint try
Put up a "kitty gate" to keep out the furry hellions.
And began applying - to apply we dipped the brush in the wax and STRONGLY brushed it onto about 6 lines of flooring at a time. The idea is that you're brushing it into the wood, so really bear down. Then we used scotch pads to scrub those 6 boards (getting any last wax into the wood we could) and then wiped those down with a clean white cloth. In the picture below you can see that the back part of the floor (that is lighter) has all of these steps done. The closest part only has the first step done.
Apply Wood Wax Finish to floor. We let it set for about 5 minutes.
Scrub with Scotch Brite Pad
Then wipe ALL excess off with a clean cloth
Make sure to tilt your head at all funny angles to see if there are any shiny spots which would indicate wax left on top of the wood.
Then let it set for 8-12 hours before applying a second coat if you choose to do one. We think it darkened a little after doing a second coat. But not much.
We are SO excited about how this has been turning out.
Also, a fun part is that while it just has wax it's super slippery so you can go all "Risky Business" if you want!
