I just saw this, Itsoi. I left the mustard on there for 24 hours and then cleaned it off. It faded completely after a short time (maybe a couple of days, I can't remember). I never heard about conditioning it, that could be a good idea but we've been pretty harsh on ours for the past 3 months and it's holding up really well, so might do that after a year or if a specific room needs it before. I felt that the oil finish would be easier for me to do touch ups on if I needed to. Still have construction going on but we've been living here for the past 3 months. And we routinely throw balls and toys for our dog down the long runway of the living room/hall and I've yet to see her nails scratch up anything! It's been pretty impervious to our kids dripping water in the kitchen also. I don't know how it will look in 5/10 years but at the moment, I'm still really happy with our choice. It seems like a very low maintenance, easy to clean (doesn't show much dirt/dust!) floor. We paired the Rockwood Claystone with BM OC17 on our walls and like the color combo. If you're leaning towards buying it, just buy 1 box and pop it together somewhere you can look at it for a week or so. I think you'll get a pretty good idea then if you like it or not. And if you like it, you can reuse it, win win! Good luck!

appreciate @SJ McCarthy agreed wood is wood. I've had cork before from prior owner, several residences ago and it is warm underfoot but not for us. Not sure if cork was maintained well or not but it wasn't in great shape when we bought that house so we had the discolored cork floor professionally removed and replaced with HW. Fridge water line and later on Fridge leaked in the back, needed wood floor replacement, not planning on wood in our next home (no Laminant/Engineered either after trying Laminant in our next residence (moisture caused swelling of the Laminant planks)). Engineered planks had cupping due to moisture by kitchen appliances.

i have had nothing but issues with this product! i have had the company i purchased the product from come out, months with no answers, finally got a company rep out to review the product in my house....still no answers back from the manufacturer! my house humidity is around 32%-37% totally within canadian home builder standards, not to mention the product is sold as 100% water proof?? how is that possible when they are concerned about humidity that has been proven by the rep not to exceed industry specs??

There's a reason why you can't find much information on this. It's probably a bad idea. You should expect some unevenness and lapping on the stain. Wood will only absorb so much oil based stain. The depth of color is controlled by how much stain can penetrate and any excess is wiped off. In my experience, water based stains don't have the same limit and are almost certain to have imperfections. It soaks in quickly and applying more over the top generally makes it darker. The most successful one we did involved taping off runs so that it could be applied and worked from both sides, like a piece of furniture, trim, cabinet or door. Then we applied two coats of urethane, masked off the stained portion and stained and urethaned the remaining strips. Then we pulled all the tape and applied one last coat of finish. Here's the Varathane product page which doesn't mention floors. https://www.varathanemasters.com/en/products/water-based-stain "Great for furniture, cabinets, doors, trim and more" And it says it's sold only in quarts. It's easy to make a sample look good but much harder when you must do multiple runs and longer runs. If you're going to allow an attempt to do this, choose a separate room to do first. so the whole thing won't have to be done if/when it doesn't work.
