Oh my, oh no. Oh jeesh. Where to start? When I last left you I showed you a sneak peak of installed tile. This was apparently the DIY blogger version of counting ones chickens before they have hatched.
Let me back up: after the walls had been primed and painted Jason installed the concrete backerboard. Neither of us know much about tiling, but from what I have read it is 100% necessary for floors with a plywood subfloor as we have. When I selected it, I bought 1/4 inch backerboard as opposed to 1/2 inch to minimize the height difference in the transition between the laundry room and the hardwood hallway. Seems reasonable... To someone who has no idea what they're doing. Apparently you need a certain thickness of floor to use the 1/4 inch backerboard. I was up in the middle of the night worrying about it. Would my floor sag? Would the tiles pop off? How hard would it be to remove? I checked the subfloor in the morning and it appears we have the right thickness. Phew, dodged that bullet. Yours truly learnt how to screw in the backerboard and also did all the taping and mudding (exactly like playing with wet sand and as fun as I always imagined it to be - I'm weird, I know).
Time to lay the tile! Wait! Time to
pretend to lay tile! We tried a few different layouts with the goal being that we would have as many whole tiles / large cuts along the side of the room that is visible and with all the necessary tiny cuts against the side that will be hidden by the washer/dryer and sink. We also decided on a 1/3 offset brick pattern (i.e. The tile is 24" in length so we staggered the next row 8" in).

We opened the boxes of tile and checked them all for chips. They were in generally very good condition and very uniform so we didn't need to worry about mixing up the boxes too much.
As you can see in the pictures we used a QEP latch levelling system which, by the by, comes in two separate packages that you have to buy individually. I didn't realise that originally and only brought home the little yellow wedges. That will teach me to review a product before I bring it home! Back to Home Depot to get them. Oh speaking of reviewing the product, it also calls for a 3/8"notched trowel for thinset because it causes your tiles to sit a bit higher and therefore they won't pick up the thinset if you use a 1/4" notched trowel. I didn't read that ahead of time either. Whoopsie.
Jason spent all Sunday cutting and laying the tiles beautifully. Between that and his real job he was exhausted so after a full day he made one critical error. In the second to last row he laid a whole tile where he should have laid an 8" tile. That would have totally thrown off the pattern but we quickly realised we could hide the whole tile under the washer and cheat by putting an 8" tile beside it so the pattern would still look right in the visible areas.
Great. Job well done! Now on to grouting. I had the pleasure of donning steel toes boots and kicking out the lash system. It was a delight. Seriously. So satisfying to kick stuff and send it careening all over the room. Until I realised a tile was loose.
Darn it!
Then more loose tiles. Then this (cover your eyes, this isn't for the feint of heart):
More than 1/3 of our tiles didn't stick. What gives???
Well, after a small panic attack I went searching for answers and solutions. Here's the trifecta of blunders that I think caused the problem:
1. I traded in ceramic tiles for porcelain without considering if I needed different thinset. Porcelain is not as porous and does not absorb / allow water to evaporate like ceramic so the thinset I bought dries too quickly and didn't adhere completely (makes sense since when I lifted a loose tile it was literally dripping with water underneath)
2. Wrong sized notches trowel. We should have used a 3/8" not a 1/4.
3. Not enough back buttering of the tiles to help adhesion.
The solution? Carefully pull out the loose tiles, scrape the thinset off the backerboard and off the back of the tiles and redo it with modified thinset intended for porcelain tiles.
So we're back at it again today. That puts us two days behind the imaginary "if everything goes exactly according to plan" time line. The good news is that the tiles that were initially laid incorrectly did not adhere so we get a do-over at laying the pattern perfectly!
What can you and I both learn from this? Tiling is bloody complicated! Oh and you should always do your homework and make sure you have the right tools for the job - you can't just swap one material for another and forget that all the things you had previously bought might not work with what you want to do.

Keep fighting the good fight and happy DIYing!
