One other thing I thought about the other day that I forgot to mention is I used a method where you slightly dampen the floor with a sponge before applying the stain, it keeps the stain uniform and keeps it from grabbing to dark. You don't want to saturate it though, I'd take the sponge and do several boards then apply the stain, repeat the process as you go along. I did use the orbital, I rented it from Home Depot, they didn't have a drum sander handy when I took it back and that's how I ended up at Menards. I see why these places rent you equipment...they make a small fortune off selling you the supplies needed, the sandpaper cost are pricey. Yeah I had planned on doing a blog when I taught my son this last summer how to do underlayment and install vinyl flooring but they came up with that crazy RC bull crap which just wasn't sitting well with me, if I spend time doing something the last thing I want it some pop up telling me I have to wait I've run out of credits. I had that blog, one about new gentrification happening down the road and a blog composed of all our family outings we do during the summer to different parks and the versatility that each offered in activities. I just said to heck with it. Bad enough you spend time doing stuff for a couple pennies, if that, then be told sorry you are out of resources.
