Changing tiles in the kitchen - how much can you spackle?

[DennisK]

We have tiles on double gypsum board and in some places the nearest gypsum comes off when I tear it down... It's about areas of approximately 10-15 cm square; would it work with filler (perhaps there's a stronger one?) or do I need to replace the gypsum/put on renovation gypsum?

What do you use to sand down old adhesive and grout?

Fill with husfix or a similar non-shrinking product. I believe there's some sort of gypsum-based product that also works.

In principle, you can fill holes of any size; it's more a matter of when it becomes too much, it's easier and cheaper to replace the drywall instead (so I've been told).

The only thing I would worry about is possibly the thickness. Since thick layers take a LONG time to dry with certain products, but it shouldn't be a major issue here.

OK. So far there are at least no damages deeper than 13 mm minus the paper on the back... so it should work.
By the way, it's significantly worse to remove the tiles (without causing major damage) on the small piece on the side of the kitchen counter - there it's enkelgips...

Plaster in use... dries in a jiffy

I think the easiest way is to try to break off large parts of the plaster with tiles on them and then put up new plaster.

Tiling over the old tiles is even easier, though.

If you're going to use filler with husfix etc, it involves a lot of filling and sanding, which you can avoid if you replace the plaster. Filling is probably the most tedious thing there is.

Sanding a lot is something you have to do if you can't fill...
Then it should be tiled, not painted... i.e., not the same finish... :

I can attest to that... I also took big chunks of the wall with me when I tore out the tiles in the apartment. The biggest piece was about 2 cm deep and about 10x10 in size. It worked fine to putty, but it took a hell of a long time and many fillings because it sinks in. But it worked out in the end anyway. And it turned out well!

As usual, I was unclear. The time I used the knock-down + house-fix method, I also had to sand down a lot of old tile adhesive that didn't come off everywhere. In other places, there were big holes in the drywall, so in the end, it was a lunar landscape. Not really boring to spackle, just to sand. Ugh.
