Fusion Pro grout feedback request/input

Probably already discussed but cant find.
My Shower grout lines (1/4") have lots of hairline cracks, too intact easily take out.
If I use grind/thin out the damaged area with a grout saw, will Fusion Pro bond to old grout (at least as well as a normal powdered grout will)?

So I finished 1 shower wall with fusion pro yesterday, 3sq feet at a time, cleaning as I went. No haze.
But now 18hours later it has shrunk significantly over night there are spots where the edge of the tile is exposed again.

Do I apply a 2nd coat dig it out, or something else?

One huge advantage of this stuff - no need to dig any out. Just apply it over the top.

Quick Reply, thank you.

Reexamining 3 hours later, some of the dimples, are beginning to look like pinholes, any way I mucked up the install?
I only did the smallest shower wall yesterday 15sq' 1/4" x 3/8" deep grout lines, used almost a full quart. Applied for 3-4min, cleaned for 10-15min.

Should I wait a few more hours and do a 2nd coat?

That's a pretty good sized joint. You should plan on two applications. The first one will shrink up on a wide joint.

Should I wait the 3 days to reapply or do it now?

(consensus all over the internet is you cant grout over grout, otherwise I wouldn't have removed the old grout?)

IF you used old style cement based grout you cannot grout over it.

BUT since you used Fusion, you CAN grout over it.

The photos look like you're using too much water for clean up or while installing.

Welcome, Bob.

Moved your questions from that technical thread to a project thread of your own.

It'll help if you'll attach your photos from storage on your computer using the paper-clip icon above the Reply dialog box so they'll appear permanently in your thread.

Sorry for the novice questions. Going to make this a 2 parter:

1)A few spots thin set came out with the grout, exposing the cement board, I dont want to risk water getting between the board and thinset.
My sponge was thoroughly rung out, BUT droplets did still form, would those droplets soak through/compromise the grout?

2) Numbskull who put in the shower grouted with thin-set, I thought little cracks in grout line was grout failing, which is why I regrouted turned theyre just shrink cracks, no soft spots or crumbling joints.

Taking out 1/4" 25 y/o thinset using a multitool and 1/8" dremel grout blade tool 25min per foot cutting along either edge of the joint.

The blade is too narrow to evenly file the whole joint.

Can I file 1mm off the surface of the joints and gouge a 1/8" wide line down the middle (so the grout can "grip") and regrout?

Maybe just coat the other walls with grout renew call it a day?

Bob, I doubt you did anything wrong. Any grout that stays wet in the joint yet sets up on the face of the tile too fast will be hard not to wash the joints too low.
Steve says to remove the grout 1/8 below the tile surface. That's what I would do.

The point of my long drudgerous post was, between the width of the joint and the hardness, evenly filing it down would take weeks. Taking full joints out is faster but exposes the cement board.

I have a lot of bad options, no good ones. The only positive is its so hard and smooth, I can carve a joint inside the existing joint fill it up with grout, and know it will bond like its tile.

One of the worst spots... this is all thinset with some hard smooth material as waterrpoofing

Here is 5-10 passes with the multitool, 1/8 inch blade either side of the joint stuff so hard I shaved the tiles along with the "grout" without noticing...middle is still at the original height, wont crack off no matter how deep I go.

This was multiple steps of the process, chisel/rake/stanley knife/screwdriver couldnt take the center ridge off. needle pliers can bit off little bits but leaves cracks behind... you can see in the 3rd shot cement board exposed in places

I should have saved time/money stress and caulked over all the joints. Or jest left it alone. Mistake of a 1st time homeowner

p.s. thank you all so much for the tips, this has been an awful experience
