Hi Pearl. I used a TEC premixed grout. I explained to the guys at the John Bridge Tile forum that I was tiling over 400 sq. ft. in my spare time, and it would take me weeks (actually months, but I took the summer off). I said that at times I might only get 25 sq ft done and would not be able to grout it all at once - and that there was the possibility of being interrupted to deal with the family:) One guy suggested a premixed grout, and specified a type which I could not find in my area. I know TEC is a pretty good brand so I used their's instead. I also was very tired of mixing up powders - I would mix the thinset in my garage and lug it down to the basement so the thought of a premixed grout was lovely - no mixing, snap the lid back on when interrupted and consistent color. I think it is twice the cost of powdered, but the perks outweighed the cost given the chore. I used the Pearl color. It takes 24 hours before you can use the floor. On a smaller job I would not mind the powdered, though the color can vary if you add more or less water - so be consistent with every batch you mix. This is what I used: https://www.menards.com/main/flooring-rugs/tile-stone/tile-installation-maintenance/tile-grout-caulk/tec-reg-ready-to-use-premixed-grout-647-1-2-gal/p-1444432148471.htm

I repriced the cost to finish the downstairs all in wood and it's more than double what I initially stated but at this point going with something other than hardwood would really look like a hack. I do have some wood leftover from my kitchen and a friend has a few cases from a leftover job also so I'll save a little there. The more I think about it the more it makes sense to complete this with hardwood. The only other choice is to just throw down carpet when I'm ready to sell but I hate doing something half-azzed. I'd rather do it right once and be done with it. I'd be wasting my time trying to cheap out on this. Thank you

Following. Would love more photos since my search is not turning up much.
