ᐅ Covering Old Tiles with a Membrane? Experiences!

The next chapter of my kitchen renovation.
My husband is strongly refusing to remove the old tile backsplash in the kitchen.
A glass splashback is not an option.
So now my idea is to use tile decals. The related pictures I found online look good.
They are also used in bathrooms, even directly in the shower.
In the kitchen, they are generally subjected to less wear than in a shower.
Has anyone here had experience with such decals? I have found a manufacturer who makes the decals from the same material as automotive vinyl wraps.
Those have to withstand quite a lot as well.
What do you think? A great or a bad alternative?
Thanks in advance for your eagerly awaited replies.

Unfortunately, I’m not experienced with this myself, but I have seen something like it on TV and the results looked really good. Alternatively, tiles can also be painted over (probably with a special type of paint, I suppose), maybe that could be an option for you?

Have you checked out IKEA wall panels?

I see fewer issues with the tiled backsplash than with your floor:
gluing, painting, cleaning... everything is involved.
And if it doesn’t hold, you can replace it with something new.
Panels are not only available from Ikea (after all, you don’t want a standard kitchen 😉 ), but come in all kinds of finishes like wood, solid colors, textured, smooth—any style can be realized.
I would base the choice of film/foil on the substrate: the more textured the tiles, the harder it is to glue and adhere.
For thin, rigid panels, you can use external construction adhesives.

Ikea panels are not glued but screwed into aluminum frames. This is a clean solution since the size is standardized, allowing you to easily get a new pattern and replace it if it no longer fits. Ikea panels are also unusually affordable for kitchen use. The nightmare of the TodayDishwasherontope consultant. Karsten

We once had some in our second-to-last rental apartment, including in the shower. They lasted without any issues for 2 years (until we moved out), and until then there were no signs of wear at all. We purchased them back then from a supplier called "Fliesen-King." I can recommend them!
