Back Butter?


Doing a 28 sq.ft half bath. The tile they chose for the floor is similar in size to subway tile but has a brick look to it and irregular sides/ends.

What size trowel do you like for this and would you back butter?

Thanks.

Re: Back Butter?


I would probably just use my 1/4" trowel as you can angle it to change depth, and always back butter if even lightly. Just feel like back buttering creates a better bond. If ceramic it gets a quick sponge to add water into the tile, before back buttering.

There are folks with far more experience tiling than myself though...like Angus.

Back buttered tile sucks when doing demo.

If it is ceramic quick wipe with a damp sponge, tight back butter.

Porcelain, dry wipe, back butter. Wet cuts, you need to dry porcelain tile.

1/4” trowel should be fine. Make sure the floor is flat.

What size tile? If they're 3x6 or something similar, forget the backbuttering and just get to it. Mix your thinset on the creamier side and work fast. Trowel size depends partly on how flat the floor is.

Porcelain per the TCNA requires back buttering no matter the size.

Sometimes I think they require it because so many folks can't mix or apply thinset worth a ch..

Skip to the 4:00 minute mark and it is clear back buttering is worth it.

Clips?

I have only tiled 10-12 times. Not sure I know what a clip is.

Re: Back Butter?


I always called them spacers. Yeah, have used them every time I've tiled...

Re: Back Butter?


Those aren't spacers, Rob. They're clips that grab the tile from both top and bottom so the faces are perfectly aligned with no "lippage". An Italian artisan might sneer at them, but they're a gift from heaven for us amateurs.

All the non bbed tile clearly had coverage issues.

So my takeaway from that vid is: If you use ditra bbing doesn’t do much.

My takeaway is if I anticipate having to demo my own tile job don't back butter.

I have a tile job coming up that has cracked grout and tiles. Chances are when I demo I will find there are coverage issues, and they are probably set on the plywood directly. I insist on using Ditra, and going below to shore up the flooring with blocking. Quality of work counts! For others there are hotel and chain restaurant tile jobs.
