I'm almost done removing the old flooring in my house and am having last minute second thoughts. Also not having much luck Googling anything that yields useful info I can put much confidence in... I am trying to become a DIYer rather late in the game, so any advice is appreciated! I am debating with going with a stained and polished concrete floor. My house is very "mod" and the look should work well. The slab is in good shape but covered with black "cutback" adhesive. I would need to somehow remove this layer of adhesive and possible polish the concrete underneath. I am envisioning some kind of rotary floor machine being involved. I don't know if that's a safe assumption, whether I can rent and use such a thing myself, or what to do about the many tight spots that a large machine would not reach. Other option I am about to proceed with is to lay slate tile. It is going to be a LOT of work, as I have planned a border, and a 45 degree angle for the main tile. Add that there is a lot of space that flows together with many odd angles involved, and it is going to be a pretty daunting task to tackle. Just wondering if I can strip, polish, groove and stain the concrete myself and save work and money. Thoughts? Thanks!
