Remove tiles from the drywall?

Hello,

we want to remove the tiles in our bathroom. The tiles in the shower area are rather unproblematic, but the tiles on the [Vorwandkonstruktion] are more so (about 4.5 m2). I have read so much in forums that it is very difficult or even impossible to remove the existing tiles from the drywall (without damaging the gypsum boards).

Is it better to lay tile on tile in this area? Certainly, there will be problems with deep sockets, fittings, etc., but the tiles underneath will remain. I am not entirely sure about the adhesion.

Or should we try to remove them anyway and then fill the walls? We do not necessarily want to remove the entire gypsum board.

Thank you.

Presumably, it is faster to tear off the tiles and redo the drywall than to carefully try to separate tile adhesive and drywall without damage. I assume that in doing so, the green cardboard layer with the impregnation will be torn off and it will ultimately be redone anyway. But that's just a layman's opinion,

that it is very difficult or even impossible to remove the existing tiles from the drywall

If glued properly, I would consider "very difficult" too strong and argue for "impossible."

Is it better to lay tile on tile at this point? Certainly, there will be problems with deep sockets, fittings, etc., but the tiles underneath will remain intact. I'm not entirely sure about the adhesion.

If you can handle sockets etc., then that's no problem. If necessary, just apply concrete primer beforehand. At the latest then, it should hold like a bomb.

Thank you. I have found that the wall in the shower area (2.5 m high, 1 m wide) is also a drywall construction. I think it makes sense to remove all drywall panels with existing tiles, install new drywall panels on top including new tiles. The problem I see is not damaging the existing substructure (probably made of steel) during the process. I assume the screws are under tile adhesive and filler. How can these be removed without bending or somehow damaging the substructure?

Hello,

I just tried to remove the tiles from the drywall panels. It doesn’t look too bad, the adhesive is still on, but I was able to remove it with a grinder or fill in where there are damages.

In the shower area it’s worse, I found something like plaster there (green) and a hammer drill really makes holes in it. There must be a concrete wall behind it. Was something sealed with drywall back then?

How can it be repaired? It will be primed anyway afterward and resealed/re-tiled with new tiles.

In the end, the drywall panels were completely removed because holes had formed in many places. New panels and new tiles were installed on them.
