I said I would post a final cost for the project and here it is:
HTML:
| Versabond Thin Set Mortar | 13 50ib bags at $15 | 210 |
| Poleyblend sanded grout | 5 25ib bags at $15 | 90 |
| Miracle Grout Shield | 7 70oz at $27 | 200 |
| Red Guard Sealer | 1 Gallon | 50 |
| 12x12 Porcelain PEI 5 Tile | 900sf at $0.67/sf | 650 |
| Buffer and Dimabrush | 1 day rental (HD) | 150 |
| Labor | 850sf at $2/sf | 1700 |
|----------------------------+---------------------+-------|
| | Total | $3050 |
I probably could have done better on Labor. I hired a company which simply contracted out a guy, and offered very little otherwise. They probably pocketed 400 bucks. The arrangement is that I did the prep work and someone would just showed up start laying tile, so I should have worked it out with a private individual! Labor took 4 full days with one tile guy. On the third day a second tile guy also worked for the day helping to cut the edge pieces. I'd say ~40 hours labor.
I got a good price on the tile from Lowes. But, home depot and Lowes both routinely run deals on tile at less than 1$/sf that's got all the right stats, PEI 5, non-slip, etc...
At first I was hesitant about grinding the concrete, I had never done it before, and it seemed like a nasty job, but there was some type of a sealer down from a prior owner and it wasn't clear to me if it needed to be grinded or not. To remove doubt I decided to go ahead and grind it down since I was investing a few thousand on the floor. However, it turned out not to be a very big deal. I went down to Homedepot and rented a floor polisher and a dimabrush, they were helpful at rentals, explaining what I needed. I think I got it all done in the half day rental period, and it really wasn't bad at all!
Thank you to the very helpful people on this forum and this thread for advice, direction, encouragement. I would never have considered porcelain tile if I had not been lurking here. Now that it is done, and I've lived with it for a few months I know that I made a great choice, and I'm really happy with it. I know the real test is 5 years+, but until then...
